Supporting young people through the COVID-19 pandemic and beyond: a multi-site qualitative longitudinal study

BackgroundThroughout the COVID-19 pandemic, youth have experienced substantial stress due to abrupt changes in education, finances, and social life, compounding pre-existing stressors. With youth (ages 15–26) often at critical points in development, they are vulnerable to long-term mental health challenges brought on by pandemic trauma.MethodsTo identify youth experiences throughout the pandemic and examine changes over time, we conducted semi-structured interviews among n = 141 youth in two Canadian provinces (Ontario and British Columbia) and across the country of Ireland at three time points over the course of more than one year (August 2020-October 2021). We conducted a qualitative longitudinal analysis using an inductive content approach.ResultsCategories identified were (1) coping with hardship; (2) opportunities for growth; (3) adapting to new ways of accessing services; (4) mixed views on the pandemic: attitudes, behaviour, and perception of policy response; (5) navigating COVID-19 information; (6) transitioning to life after the pandemic; and (7) youth-led recommendations for government and service response. The findings also reveal trends in health and wellness in accordance with prolonged periods of lockdown, changes in weather, and return to normalcy after the availability of COVID-19 vaccines. Key recommendations from youth include incorporating youth voice into decision making, communicating public health information effectively to youth, enhancing service delivery post-pandemic, and planning for future pandemics.ConclusionsThese results provide insights into the extensive longitudinal impacts of the COVID-19 pandemic on young people across three geographical locations. Actively involving youth in decision making roles for future pandemics or public health emergencies is critical.

Drivers of COVID-19 Vaccination among Eligible Adults in Abuja, Nigeria: A Mixed-Methods Study Using the WHO Behavioral and Social Drivers of Vaccination Framework.

Despite the availability of COVID-19 vaccines, Nigeria still faces significant COVID-19 vaccine hesitancy, with only 60.7% of the eligible population fully vaccinated as of 20 March 2023. Our study, part of a community-based effort to improve knowledge and uptake of the COVID-19 vaccine in the Gwagwalada Area Council of Abuja, the Federal Capital Territory (FCT) of Nigeria, utilized the WHO's Behavioral and Social Drivers (BeSDs)-of-vaccination framework to examine the drivers of COVID-19 vaccination among eligible adults. This was a mixed-method study with focus group discussions (FGDs) and in-depth interviews (IDIs) involving 40 purposively sampled participants. We triangulate qualitative findings with data from a household survey of 1512 eligible adults identified using a two-stage systematic cluster sampling approach. All data were collected from the 1-18 November 2022. The household survey showed 46% COVID-19 vaccine uptake, with Pearson chi-square and Fisher's exact test showing significant associations between vaccine uptake and gender, religion, and education. Multivariate logistic regression showed that confidence in vaccine safety, knowing vaccination sites and family/friends' endorsement of COVID-19 vaccination were the strongest items associated with vaccine uptake in the thinking-and-feeling, practical-issue, and social-process domains, respectively. Multiple items measuring these domains aligned with BeSD priority question, demonstrating the robustness of the pared-down framework. Qualitative data corroborated these findings. To address vaccine hesitancy and increase uptake, community-driven approaches to improve trust in vaccine safety and benefits and promote positive vaccination norms are needed. In addition, service delivery strategies to make vaccination services easily accessible and identifiable should be developed and tailored to community needs.

Lessons from the COVID-19 pandemic to strengthen NCD care and policy in humanitarian settings: a mixed methods study exploring humanitarian actors’ experiences

BackgroundThe COVID-19 pandemic and response severely impacted people living with non-communicable diseases (PLWNCDs) globally. It exacerbated pre-existing health inequalities, severely disrupted access to care, and worsened clinical outcomes for PLWNCDs, who were at higher risk of morbidity and mortality from the virus. The pandemic’s effects were likely magnified in humanitarian settings, where there were pre-existing gaps in continuity of care for non-communicable diseases (NCDs). We sought to explore factors affecting implementation of NCD care in crisis settings during the COVID-19 pandemic and the adaptations made to support implementation.MethodsGuided by the Consolidated Framework for Implementation Research, we undertook an online survey of 98 humanitarian actors from multiple regions and organization types (March-July 2021), followed by in-depth interviews with 13 purposively selected survey respondents (October-December 2021). Survey data were analysed using descriptive statistics, while interview data were analysed thematically, using both deductive and inductive approaches.ResultsInitially, humanitarian actors faced challenges influenced by external actors’ priorities, such as de-prioritisation of NCD care by governments, travel restrictions and supply chain interruptions. With each infection wave and lockdown, humanitarian actors were better able to adapt and maintain NCD services. The availability of COVID-19 vaccines was a positive turning point, especially for the risk management of people with NCDs and protection of health workers. Key findings include that, despite pre-existing challenges, humanitarian actors largely continued NCD services during the crisis. Enabling factors that supported continuity of NCD services included the ability to quickly pivot to remote means of communication with PLWNCDs, flexibility in medicine dispensing, and successful advocacy to prioritize NCD management within health systems. Key lessons learned included the importance of partnerships and cooperation with other health actors, and the mobilisation or repurposing of community health workers/volunteer networks.ConclusionsThe COVID-19 experience should prompt national and global health stakeholders to strengthen inclusion of NCDs in emergency preparedness, response, and resilience planning. Key lessons were learned around remote care provision, including adapting to NCD severity, integrating community health workers, providing context-adapted patient information, combating misinformation, and strengthening cross-sectoral partnerships.

Healthcare Provider Experiences With Unvaccinated COVID-19 Patients: A Qualitative Study.

In the setting of an active pandemic the impact of public vaccine hesitancy on healthcare workers has not yet been explored. There is currently a paucity of literature that examines how patient resistance to disease prevention in general impacts practitioners. The COVID-19 pandemic created unprecedented healthcare challenges with impacts on healthcare workers' wellbeing. Vaccine hesitancy added complexity to providing care for unvaccinated patients. Our study qualitatively explored experiences of healthcare providers caring for unvaccinated patients with severe COVID-19 infection in the intensive care setting. We used interview-based constructivist grounded theory methodology to explore experiences of healthcare providers with critically ill unvaccinated COVID-19 patients. Healthcare providers who cared for unvaccinated patients with severe COVID-19 respiratory failure following availability of severe acute respiratory syndrome coronavirus 2 vaccines were recruited from seven ICUs located within two large academic centers and one community-based hospital. We interviewed 24 participants, consisting of eight attending physicians, seven registered nurses, six critical care fellows, one respiratory therapist, one physiotherapist, and one social worker between March 2022 and September 2022 (approximately 1.5 yr after the availability of COVID-19 vaccines in Canada). Interviews were recorded, transcribed, de-identified, and coded to identify emerging themes. The final data was analyzed to generate the thematic framework. Reflexivity was employed to reflect upon and discuss individual pre-conceptions and opinions that may impact collection and interpretation of the data. Healthcare providers maintained dedication toward professionalism during provision of care, at the cost of suffering emotional turmoil from the pandemic and COVID-19 vaccine hesitancy. Evolving sources of stress associated with vaccine hesitancy included ongoing high volumes of critically ill patients, resource shortages, and visitation restrictions, which contributed to perceived emotional distress, empathy loss, and professional dissatisfaction. As a result, there were profound personal and professional consequences for healthcare professionals, with perceived impacts on patient care. Our study highlights struggles of healthcare providers in fulfilling professional duties while navigating emotional stressors unique to vaccine hesitancy. System-based interventions should be explored to help providers navigate biases and moral distress, and to foster resilience for the next major healthcare system strain.

A Dynamic Prognostic Model for Identifying Vulnerable COVID-19 Patients at High Risk of Rapid Deterioration.

We aimed to validate and, if performance was unsatisfactory, update the previously published prognostic model to predict clinical deterioration in patients hospitalized for COVID-19, using data following vaccine availability. Using electronic health records of patients ≥18 years, with laboratory-confirmed COVID-19, from a large care-delivery network in Massachusetts, USA, from March 2020 to November 2021, we tested the performance of the previously developed prediction model and updated the prediction model by incorporating data after availability of COVID-19 vaccines. We randomly divided data into development (70%) and validation (30%) cohorts. We built a model predicting worsening in a published severity scale in 24 h by LASSO regression and evaluated performance by c-statistic and Brier score. Our study cohort consisted of 8185 patients (Development: 5730 patients [mean age: 62; 44% female] and Validation: 2455 patients [mean age: 62; 45% female]). The previously published model had suboptimal performance using data after November 2020 (N = 4973, c-statistic = 0.60. Brier score = 0.11). After retraining with the new data, the updated model included 38 predictors including 18 changing biomarkers. Patients hospitalized after Jun 1st, 2021 (when COVID-19 vaccines became widely available in Massachusetts) were younger and had fewer comorbidities than those hospitalized before. The c-statistic and Brier score were 0.77 and 0.13 in the development cohort, and 0.73 and 0.14 in the validation cohort. The characteristics of patients hospitalized for COVID-19 differed substantially over time. We developed a new dynamic model for rapid progression with satisfactory performance in the validation set.

The impact of vaccine type and booster dose on the magnitude and breadth of SARS-CoV-2-specific systemic and mucosal antibodies among COVID-19 vaccine recipients

The COVID-19 pandemic has had a major impact on global health and economy, which was significantly mitigated by the availability of COVID-19 vaccines. The levels of systemic and mucosal antibodies against SARS-CoV-2 correlated with protection. However, there is limited data on how vaccine type and booster doses affect mucosal antibody response, and how the breadth of mucosal and systemic antibodies compares. In this cross-sectional study, we compared the magnitude and breadth of mucosal and systemic antibodies in 108 individuals who received either the BNT162b2 (Pfizer) or CoronaVac (SinoVac) vaccine. We found that BNT162b2 (vs CoronaVac) or booster doses (vs two doses) were significantly associated with higher serum IgG levels, but were not significantly associated with salivary IgA levels, regardless of prior infection status. Among non-infected individuals, serum IgG, serum IgA and salivary IgG levels were significantly higher against the ancestral strain than the Omicron BA.2 sublineage, but salivary IgA levels did not differ between the strains. Salivary IgA had the weakest correlation with serum IgG (r = 0.34) compared with salivary IgG (r = 0.63) and serum IgA (r = 0.60). Our findings suggest that intramuscular COVID-19 vaccines elicit a distinct mucosal IgA response that differs from the systemic IgG response. As mucosal IgA independently correlates with protection, vaccine trials should include mucosal IgA as an outcome measure.

Telehealth Preferences Among Patients With Advanced Cancer in the Post COVID-19 Vaccine Era

BackgroundFew studies have examined patient preferences for telehealth in palliative care after the availability of COVID-19 vaccines. We examined patient preferences for video versus in-person visits and factors contributing to preferences in the postvaccine era. MethodsThis is a cross-sectional survey of patients who were seen at our palliative care clinic between April 2021 and March 2022. Patients were surveyed directly their preference for either video or in-person visits for outpatient palliative care (primary outcome). We also surveyed preferences including convenience, cost, wait time, and perceptions of COVID-19 safety regarding their palliative virtual-video visit. We examined clinical factors associated with preferences with multivariate logistic regression. ResultsAbout 200 patients completed the survey. 132 (67%, 95% confidence interval [CI]: 60%, 74%) preferred virtual-video, while 16 (8%) preferred in-person visits during the COVID-19 pandemic. About 120 (61%, 95%CI: 54%, 68%) preferred virtual-video after the pandemic. Patients perceived virtual-video favorably regarding travel and related costs (179 [91%]), convenience (175 [88%]), and wait time (136 [69%]). Multivariable analysis showed concerns for catching COVID-19 from healthcare providers (odds ratio [OR]: 4.20; 95%CI: 1.24–14.25; P = 0.02) and feeling comfortable with computers or mobile devices (OR: 4.59; 95%CI: 1.02, 20.60; P = 0.047) were significantly associated with preferring virtual-video. Patients who were of Hispanic or Latino ethnicity (OR: 0.25; 95%CI: 0.09, 0.71) and had increased dypsnea (OR: 0.74; 95%CI: 0.59, 0.93) were less likely to prefer video over in-person. ConclusionPatients expressed strong preference for video over in-person visits in the outpatient palliative care setting.

COVID-19 vaccine acceptance among pregnant women: a multicentre cross-sectional survey in Port Harcourt, Nigeria.

effective COVID-19 vaccines for the prevention of severe illness have been available for more than one year now. This study was carried out to ascertain vaccine hesitancy and its associations among pregnant women receiving antenatal care in Port Harcourt, a large cosmopolitan town in Nigeria. we conducted a cross-sectional online survey over 2 months among consenting pregnant women receiving antenatal care in the 3 largest obstetric service centers in Port Harcourt to evaluate COVID-19 vaccine hesitancy and its associations. the prevalence of vaccine hesitancy was 669 (72.2%). Of the respondents, 27 (2.9%) had been infected or had a close family member infected with SARS-CoV-2, and 897 (96.8%) of them had heard of the COVID-19 vaccine; however, only 133 (14.4%) had been vaccinated against COVID-19. The safety of the mother in 260 (32.8%) and the safety of the unborn baby in 114 (14.4%) of the respondents were the reasons for vaccine hesitancy. A small proportion of women 7(0.9%) were hesitant on religious grounds. Tertiary education, use of childhood immunization for previous infants delivered, and availability of COVID-19 vaccine in the antenatal clinic at no cost to the women, were statistically significant predictors of vaccine uptake among the respondents. the prevalence of vaccine hesitancy among pregnant women in Port Harcourt was 72.2%. Higher academic achievement and availability of the COVID-19 vaccine in the antenatal clinic were predictors of vaccine uptake, while reasons for hesitancy were mostly due to safety concerns for the mother and unborn baby.

Perception and Acceptance of COVID-19 Vaccination among Nurses Working in Selected Primary Healthcare Facilities in Ethiope East Local Government Area, Delta State

Background: Knowing that social distancing and quarantine slow the spread of the COVID-19 virus and flatten the epidemic curve; it may not be sufficient to completely halt the spread of COVID-19, herd immunity gained by infection or vaccination will need to be well established within the population. However, the availability of COVID-19 vaccines may not translate into its uptake.
 Aim: Thus, the researcher explored the perception and acceptance of COVID-19 vaccination among 200 Nurses working in selected primary healthcare facilities in Ethiope East Local Government Area of Delta State.
 Method: Purposeful sampling was used to access 200 Nurses, the data was collected using a closed-ended questionnaire and analysed electronically with a descriptive statistics package on SPSS version 25.0. 
 Results: Findings revealed that the majority (60% ) of nurses have a good perception towards COVID-19 vaccination and that a large majority (62%) will readily accept the uptake. Factors influencing the uptake include; the safety of a vaccine developed in an emergency, during an epidemic cannot be considered guaranteed, trust in the Ministry of Health and National to ensure that vaccines are safe, trust in science to develop safe effective new vaccines, trust in the authorities in the fight against COVID-19, the perception of not to be at considerable risk of developing complications and having had the COVID-19 disease.
 Conclusion: Findings revealed that the majority of nurses have a good perception towards COVID-19 vaccination while only a few had a poor perception, while one-third of the participants would reject COVID-19 vaccination, two third would readily accept the uptake.

Hesitancy in COVID-19 Vaccine Uptake and Its Correlated Factors Using Multi-Theory Model among Adult Women: A Cross-Sectional Study in Three States of Somalia.

In developing countries, access to information, awareness, and availability of COVID-19 vaccines are key challenges. Somalia launched the COVID-19 vaccination in March 2021; however, the uptake of the vaccination is slow, which creates fear of further loss of life in the country unless intentional and organized campaigning and efforts are made to improve both the availability of the vaccine and its acceptance by the community. This study aimed to understand the current level of awareness, accessibility, trust, and hesitancy toward the COVID-19 vaccine among women in Somalia. To assess COVID-19 vaccine uptake, acceptance, community awareness, and hesitancy rates in Somalia, we carried out a cross-sectional mixed methods study in three regions of Somalia that were selected randomly out of the 18 regions of Somalia. A multi-theory model (MTM) was developed to identify correlated factors associated with the hesitancy or non-hesitancy toward COVID-19 vaccination among women of all ages (18 years and above). A total of 999 eligible women (333 in each district) of 18-98 years old were interviewed in March 2022. About two-thirds (63.76%) of participants reported hesitancy about receiving the COVID-19 vaccine. The theory model initiation construct indicated that behavioral confidence in the vaccine (b = 0.476, p < 0.001), participatory dialogue (at b = 0.136, p < 0.004), and changes in the physical environment (b = 0.248, p = 0.015) were significantly associated with COVID-19 vaccine acceptance among women who were not hesitant to take the vaccine. The availability of COVID-19 vaccines may not translate into their uptake. The decision to get the vaccine was determined by multiple factors, including the perceived value of the vaccination, previous experience with the vaccine, perceived risk of infection, accessibility and affordability, and trust in the vaccine itself. Public health education programming and messaging must be developed to encourage vaccine uptake among women with varying levels of vaccine hesitancy.

Online and in-store shopping interactions for non-essential experience goods

The online and in-store shopping landscape underwent transformative shifts due to the Covid-19 pandemic, potentially leading to novel hybrid shopping behaviors following the availability of Covid-19 vaccines. However, these new dynamics, especially for non-essential experience goods which were heavily impacted by lockdowns, remain relatively unexplored. Moreover, variations in such dynamics within the same product class are not well understood. This study investigates the interactions between online and in-store shopping behaviors across four categories of non-essential experience goods: clothing, shoes, watches, and jewelry (CSWJ); beauty and health products (BH); toys, kids, and baby supplies (TKB); and home, garden, and tools (HGT). Data from over 2,000 Florida residents collected in early 2021, encompassing purchase frequencies, attitudes, and socio-demographic attributes, were analyzed using separate bidirectional structural equation models. Findings indicate that the relationship between online and in-store shopping for CSWJ and TKB exhibited reciprocal complementarity effects. In contrast, BH and HGT displayed an asymmetric reciprocal relationship, with in-store shopping showing no significant influence on online shopping. Results on the mediating influence of attitudes on shopping behaviors showed that a pro-online shopping attitude and preference for alternative travel modes positively influenced online shopping frequency, while the joy of shopping and data privacy/security concerns emerged as drivers of in-store shopping across all product categories. In sum, this study underscores the presence of product-specific heterogeneity even within the experience goods class, contributing to the complex interactions between online and in-store shopping behaviors.

Awareness, acceptance, and hesitancy about COVID-19 vaccine among residents of urban and rural health training center field practice area of a medical college at Kolkata: A cross-sectional survey

Background: Effective vaccination is a successful tool for controlling COVID-19 pandemic, along with other preventive measures. Both intention to get vaccinated and barrier to vaccination played important role in COVID vaccination drive. Aims and Objectives: The present study was conducted to assess awareness, acceptance, and hesitancy about COVID-19 vaccine among the residents of rural and urban area and to assess the factors related to their attitude. Materials and Methods: A descriptive cross-sectional survey was conducted among the adult residents of urban and rural area over 6 months. Total sample size was 400. Simple random sampling technique was adopted to recruit the study participants after obtaining informed verbal consent. This process was continued until the desired number of sample size was attained. Data were compiled after collection and analysis was done. Results: Rural population had significantly higher knowledge of coronavirus and urban population knew prevention of coronavirus infection more. Correct knowledge of COVID vaccine availability was higher among rural people but higher knowledge of vaccine related information was among urban population. Sources of information were mainly from mass media. Vaccine acceptance was more among urban population, but apprehension was significantly higher among urban residents. Higher proportion of urban people was motivated significantly by the healthcare workers as well as self-motivated than their rural counterpart. Conclusion: Targeted interventions could be developed for increasing awareness of disease and availability of COVID-19 vaccines. Population-based vaccination program can decline the trend of the pandemic in long term.

COVID-19 vaccine coverage targets to inform reopening plans in a low incidence setting.

Since the emergence of SARS-CoV-2 in 2019 through to mid-2021, much of the Australian population lived in a COVID-19-free environment. This followed the broadly successful implementation of a strong suppression strategy, including international border closures. With the availability of COVID-19 vaccines in early 2021, the national government sought to transition from a state of minimal incidence and strong suppression activities to one of high vaccine coverage and reduced restrictions but with still-manageable transmission. This transition is articulated in the national 're-opening' plan released in July 2021. Here, we report on the dynamic modelling study that directly informed policies within the national re-opening plan including the identification of priority age groups for vaccination, target vaccine coverage thresholds and the anticipated requirements for continued public health measures-assuming circulation of the Delta SARS-CoV-2 variant. Our findings demonstrated that adult vaccine coverage needed to be at least 60% to minimize public health and clinical impacts following the establishment of community transmission. They also supported the need for continued application of test-trace-isolate-quarantine and social measures during the vaccine roll-out phase and beyond.

Relationship between household member vaccine acceptance and individual vaccine acceptance among women in rural Liberia

Background Despite the availability of COVID-19 vaccines, vaccination uptake remains low in Liberia. Social norms, and in particular an individual’s family preferences can have a strong normative influence on health behavior. However, few studies across the globe have explored how behavioral intent about COVID-19 vaccination among household members affects individual vaccination acceptance, particularly in rural, resource-limited settings. We respond to this gap in knowledge by analyzing data from a household survey of women in rural Liberia with the goal of understanding how household COVID-19 beliefs and vaccine behavioral intent correlated with those of individual household members. Methods Data was analyzed from a household survey of 2,620 women aged 15-49 in 2,201 households in rural Grand Bassa County, Liberia, from March to April 2021. The survey included a COVID-19 module on protective health behaviors and intention to accept a COVID-19 vaccine when available. Each household was defined as being concordantly vaccine-hesitant, concordantly vaccine-accepting, or discordant. A multivariable logistic regression model was fitted to identify correlates of concordant acceptance, adjusting for potential confounders. Results The survey found that only approximately one in three households in rural Liberia were fully COVID-19 vaccine accepting. About 42% of households had discordant views on the vaccine, while 33% had concordantly accepting views, and 25% had concordantly hesitant views. The demographic characteristics of households with different vaccine beliefs were similar. Having a household member who accepted the COVID-19 vaccine was associated with an 18.1 percentage point greater likelihood of an individual accepting the vaccine (95% confidence interval, CI=7.3-28.9%, P=0.001). Conclusions Social norms around vaccine acceptance within households are strongly associated with individual acceptance. Interventions that target hesitant households and individuals could have a significant impact on vaccine acceptance rates.

Uptake of the COVID-19 Vaccination and Associated Factors Among Health Care Providers in Addis Ababa, Ethiopia.

The COVID-19 vaccine is intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2). As a result, 12 billion doses of the COVID-19 vaccination have been given globally as of August 1, 2022. Due to occupational exposure, health professionals obtained priority for COVID-19 vaccination. However, despite the availability of COVID-19 vaccines in countries, there is a discrepancy in the uptake of vaccine among different populations including Health-Care Providers. Assessments of the factors associated with uptake of COVID-19 vaccination among health-care providers in Addis Ababa, Ethiopia in 2022. From June 10 to July 10, 2022, a facility-based cross-sectional study was carried out in Addis Ababa, Ethiopia, involving 473 health-care professionals, used descriptive statistics to summarize the participant's characteristics, and multivariable logistic regression to analyze factors affecting COVID-19 vaccination uptake. P-value <0.05 was used to determine the level of significance. The response rate of the participants was 94.2%. The uptake rate of COVID-19 vaccine among health-care providers was 359 (75.8%). Vaccine uptake was positively associated with higher perceived concerns regarding COVID-19 [AOR = 7.45, (4.041-13.754)], higher monthly income, [AOR: 2.623 (1.398 -4.923)] compared those who earned lower, being married [AOR: 2.114, (1.068-4.181)] and being advanced age (36-45) years old [AOR =0.486 (0.258-0.916)] compared to 18-26 years old. However, being female professional reduced the odds of vaccine uptake [AOR = 0.486 (CI; 0.258-0.916)] in contrast of their counterpart. The uptake of COVID-19 vaccine among health professionals is relatively higher than in earlier reports. However, this was not yet sufficient for the level required to achieve herd immunity. Hence, the Ministry of health should work in collaboration to address concerns about the safety and effectiveness of COVI D-19 vaccine to increase COVID-19 vaccine uptake. Moreover, Health professionals, social media, regular media outlet should strengthen health education on concerns of covid-19 infection.

Dengue vaccine acceptability before and after the availability of COVID-19 vaccines in Puerto Rico.

Dengue is a growing public health threat, causing approximately 400 million infections annually. In June 2021, the Advisory Committee on Immunization Practices recommended the first dengue vaccine (CYD-TDV) for children aged 9-16years with a previous dengue infection, living in endemic areas, such as Puerto Rico (PR). As the COVID-19 pandemic affected vaccine intention worldwide, we assessed dengue vaccine intention before (pre-COVID) and after (post-COVID) COVID-19 vaccine availability among participants enrolled in the Communities Organized to Prevent Arboviruses (COPA) cohort to prepare for dengue vaccine implementation in PR. We used logistic regression models to evaluate changes in dengue vaccine intention by interview timing and participant characteristics. Among 2,513 participants pre-COVID, 2,512 answered the dengue vaccine intention question for themselves, and 1,564 answered relative to their children. Post-COVID, dengue vaccine intention in adults increased for themselves from 73.4% to 84.5% (adjusted odds ratio (aOR)=2.27, 95%CI:1.90-2.71) and relative to their children from 75.6% to 85.5% (aOR=2.21, 95%CI:1.75-2.78). Among all participants, groups with higher dengue vaccine intention included those who reported previous year influenza vaccine uptake and those who reported being frequently bitten by mosquitos, compared to those who did not. Adult males were also more likely to intend to vaccinate themselves than females. Respondents who were employed or in school were less likely to intend to vaccinate compared to those who were not working. The primary reasons for vaccine hesitancy were concerns with side effects and not believing in vaccines, which should be considered during educational strategies prior to dengue vaccine implementation. In general, dengue vaccine intention is high in PR and has increased after COVID-19 vaccine availability, potentially due to increased awareness of vaccine importance during the COVID-19 pandemic.

COVID-19 Vaccine Acceptance and Hesitancy in Health Care Workers in Somalia: Findings from a Fragile Country with No Previous Experience of Mass Adult Immunization.

Coverage of COVID-19 vaccines in Somalia remains low, including among health workers. This study aimed to identify factors associated with COVID-19 vaccine hesitancy among health workers. In this cross-sectional, questionnaire-based study, 1476 health workers in government and private health facilities in Somalia's federal member states were interviewed face-to-face about their perceptions of and attitudes toward COVID-19 vaccines. Both vaccinated and unvaccinated health workers were included. Factors associated with vaccine hesitancy were evaluated in a multivariable logistic regression analysis. Participants were evenly distributed by sex, and their mean age was 34 (standard deviation 11.8) years. The overall prevalence of vaccine hesitancy was 38.2%. Of the 564 unvaccinated participants, 39.0% remained hesitant. The factors associated with vaccine hesitancy were: being a primary health care worker (adjusted odds ratio (aOR) = 2.37, 95% confidence interval (CI): 1.15-4.90) or a nurse (aOR = 2.12, 95% CI: 1.05-4.25); having a master's degree (aOR = 5.32, 95% CI: 1.28-22.23); living in Hirshabelle State (aOR = 3.23, 95% CI: 1.68-6.20); not having had COVID-19 (aOR = 1.96, 95% CI: 1.15-3.32); and having received no training on COVID-19 (aOR = 1.54, 95% CI: 1.02-2.32). Despite the availability of COVID-19 vaccines in Somalia, a large proportion of unvaccinated health workers remain hesitant about being vaccinated, potentially influencing the public's willingness to take the vaccine. This study provides vital information to inform future vaccination strategies to achieve optimal coverage.

Impacts of the COVID-19 pandemic on the infection prevention and control field: Findings from focus groups conducted with association for professionals in infection control & epidemiology (APIC) members in fall 2021

IntroductionEmergence of the Delta variant in 2021 changed the pandemic landscape and led to healthcare surges across the US, despite availability of COVID-19 vaccine. Anecdotal information indicated that the infection prevention and control (IPC) field was changing, but formal assessment was needed. MethodsFocus groups (6) were conducted with APIC members in November and December, 2021 to elicit infection preventionists' (IP) opinions changes to the IPC field due to the pandemic. Focus groups were audio recorded via Zoom and transcribed. Content analysis was used to identify major themes. ResultsNinety IPs participated. IPs described multiple changes to the IPC field during the pandemic, including being more involved in policy development, the challenge of transitioning back to routine IPC while still responding to COVID-19, increased need for IPs across practice settings, difficulties in recruiting and retaining IPs, presenteeism in healthcare, and extensive burnout. Participants suggested approaches to improve IPs' wellbeing. ConclusionsThe ongoing pandemic has brought significant changes to the IPC field, including a shortage of IPs just as the field is expanding rapidly. The continued overwhelming workload and stress due to the pandemic has resulted in burnout among IPs and the need for initiatives to improve their wellbeing.

Pharmacovigilance des médicaments et des vaccins contre la COVID-19 durant la pandémie : comment le Réseau français des centres régionaux de pharmacovigilance a relevé le défi ?

The pandemic subsequent to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus resulted, for the French institutional pharmacovigilance, in a "health crisis" in 2 phases: the coronavirus disease 2019-"COVID-19" phase during which the missions of the Regional Pharmacovigilance Centres (RPVC) were to detect a possible impact of drugs on this disease, as whether existed a possible aggravating role of certain drugs, or the safety profile of drugs used for the management of COVID-19 could evolve. The second phase followed the availability of COVID-19 vaccines, during which the RPVCs' missions were to detect as early as possible any new serious adverse effect, source of a potential signal that would modify the benefit/risk ratio of a vaccine and require the implementation of health safety measures. During these two periods, signal detection remained the core business of the RPVCs. The RPVCs had to organize themselves to handle an historical surge of declarations and requests for advice, whereas the RPVCs in charge of monitoring vaccines had to deal with an extraordinary dense activity over a long period of time, in order to produce in real time and on a weekly basis, a summary of all the declarations and an analysis of safety signals. The national organization put in place made it possible to meet the challenge of real-time pharmacovigilance monitoring of 4 vaccines with conditional marketing authorizations. Short-circuit efficient exchanges with the French Regional Pharmacovigilance Centres Network was paramount for the French National Agency for medicines and health products (Agence nationale de sécurité du médicament et des produits de santé) to develop an optimal collaborative partnership. The RPVC network has shown agility and flexibility, has been able to adapt swiftly and demonstrated its effectiveness in the early detection of safety signals. This crisis confirmed the superiority of manual/human signal detection as the most effective and powerful tool to date, to rapidly detect a new adverse drug reaction and enable to elaborate rapid measures of risk reduction. In order to maintain the performance of French RPVCs in signal detection and to monitor all drugs as they should and as expected by our fellow citizens, a new funding model correcting the inadequacy of RPVCs' expertise resources in relation to the volume of reports should be considered.

Can we move beyond vaccine apartheid? Examining the determinants of the COVID-19 vaccine gap

ABSTRACT While global health leaders call disparities in access to COVID-19 vaccines an ‘apartheid,’ this gap is not the first such disparity. The recurrence of these gaps in low and middle-income countries and especially in Africa, raises questions about their determinants and about the persistent failures of global health institutions to remediate them. We interrogate these determinants and questions by examining: (1) the distribution of COVID-19 vaccines; (2) primary determinants of vaccine access including availability and affordability; (3) factors affecting availability (hoarding, COVAX, and manufacturing capacity); and (4) factors affecting affordability (pricing, intellectual property rights (IPR), the TRIPS waiver and a potential pandemic treaty). We conclude that IPR constrained the affordability and availability of COVID-19 vaccines in ways inadequately addressed by COVAX and a waiver compromise thwarted by political, corporate, and philanthropic interests. While stronger limits to IPR in a pandemic treaty and a reformed International Health Regulations will not resolve structural inequities, they could meaningfully expand LMIC autonomy to protect public health. We urge equity-seeking Global South and North actors to fight for such IPR reforms as small and meaningful steps towards a more equitable global health order. Otherwise, criminally racist ‘apartheids’ will continue to be the norm when it comes to the distribution of essential health goods during global health emergencies.
