A Latent Profile Analysis of COVID-19 and Influenza Vaccine Hesitancy among Economically Marginalized Hispanic Mothers of Children under Five Years of Age in the US.

Rates of COVID-19 and influenza vaccine coverage among Hispanic young children continue to be low in comparison to other racial and ethnic groups in the United States. This study utilized a person-centered approach to understand COVID-19 and influenza vaccination hesitancy for young children under the age of five among 309 economically marginalized Hispanic mothers. Drawing on the cultural health belief model, in 2022, following FDA approval of the COVID-19 vaccine for young children, a latent profile analysis was conducted from which three profiles emerged. The Low Acculturation group (Profile 1), was notable for lower acculturation, moderate cultural medical mistrust, lower access to vaccines, and higher financial security. Compared to Profile 1, the two remaining profiles had higher acculturation and lower levels of financial security, but differed in that the High Acculturation group (Profile 2) had higher vaccine accessibility and the Moderate Acculturation group (Profile 3) had higher cultural medical mistrust. Relative to other profiles, Low Acculturation mothers were more likely to plan to vaccinate their child against current and seasonal COVID-19 and seasonal influenza, report that their child's health provider recommended the COVID-19 shot and reported lower COVID-19 and influenza vaccine mistrust. However, they also reported lower vaccine accessibility and moderate levels of cultural medical mistrust. The study highlights the importance of developing person-centered public health strategies that draw on Hispanic cultural values and consider diversity within lower income Hispanic populations to increase future pediatric COVID-19 and flu vaccination coverage among young Hispanic children.

COVID-19 Vaccine Acceptance and Hesitancy among People Living with HIV: Review and Meta-Analysis.

This study aims to estimate the COVID-19 vaccine acceptance and hesitancy among people living with HIV (PLWHA). A search for observational studies was conducted in five databases and preprinted literature. Summary estimates were pooled using a random effects model and meta-regression. Of 150 identified studies, 31 were eligible (18,550 PLWHA). The weighted prevalence of COVID-19 vaccine hesitancy overall was 29.07% among PLWHA (95%CI = 24.33-34.32; I² = 98%,) and that of vaccine acceptance was 68.66% (95%CI = 62.25-74.43; I² = 98%). Higher hesitancy prevalence was identified in low/lower-middle income countries (35.05; 95% CI = 19.38-54.78). The heterogeneity was explained by the risk of bias, region, and year of data collection. The findings conclude that the COVID-19 vaccine hesitancy rate remains high, especially in low-income countries. Evidence-informed interventions aimed at increasing COVID-19 vaccine acceptance at the national and individual levels ought to be designed to increase COVID-19 vaccine acceptance among PLWHA.

VACCINE BREAKTHROUGH CASES AMONG HOSPITALISED PATIENTS IN THE INTENSIVE CARE UNIT FOR COVID-19 IN NORTH-EASTERN BULGARIA

Background: COVID-19, caused by SARS-CoV-2, continues to spread globally, with vaccines being the most effective way to control the pandemic. Studies show a significant reduction in infection, hospitalisations, severe disease, and death after vaccination.The aim of the study was to determine the share of breakthrough infections among critically ill patients with severe COVID-19 who had been admitted to the intensive care unit (ICU) of a hospital at the beginning of the delta-variant pick. Material and methods: For a period of 10 months a total of 740 patients diagnosed with COVID-19, were treated in the intensive care unit of the University Hospital “St. Marina-Varna”, with ersons. Information on the vaccination status of all 740 hospitalised patients was extracted from the National information system "Register of immunized persons against COVID-19", including the type and date of COVID-19 vaccine administration, where available. After that, descriptive statistics were performed with the collected data. Results: Out of 740 patients, 19 (2.6%) had received at least 1 dose of vaccine, and 721 (97.4%) - none. Only ten (1.35%) of the studied everely and critically ill patients had completed the vaccination cycle (without a booster dose). Conclusion: Our findings show that when fully administered, vaccines are highly effective against laboratory-confirmed SARS-CoV-2 infection leading to ICU admission. Our findings reinforce the value of widespread COVID-19 vaccination, underscore the importance of completing the vaccination cycle for either of the mRNA-based vaccines, and may help motivate persons who remain hesitant about being vaccinated.

Factors Associated with COVID-19 Vaccination Hesitancy and Most Frequently Vaccinated Status in a Japanese Population-Based Sample

While many countries across the world have had difficulty in providing continuous coronavirus disease (COVID-19) vaccine boosters, in Japan, the number of COVID-19 vaccinations has increased rapidly in the past two years to the point where the vaccination booster numbers are now at the highest level in the world (by March 2023). Against this backdrop, this study aimed to determine the characteristics of individuals who either refused to be vaccinated or who were vaccinated multiple (five) times during this period. We analyzed data from a sample of 3710 Japanese adults that were collected in a nationwide, cross-sectional Internet survey that was undertaken in March 2023. Several demographics (e.g., age, education level, marital status, job status), medical conditions, daily smoking, and mental health/psychological factors (i.e., perceived stress, anxiety symptoms, loneliness) were associated with not having been vaccinated. Although the most frequently vaccinated status was also associated with some demographics (e.g., age, employment status), medical conditions, and daily smoking, other predictors such as having a COVID-19 infection history were unique to this outcome. Moreover, age-stratified analyses showed that depression (OR: 2.05, 95%CI: 1.08–3.89) and anxiety (OR: 3.87, 95%CI: 1.80–8.31) symptoms were associated with higher odds of being unvaccinated while loneliness was associated with lower odds for the most frequently vaccinated status (OR: 0.72, 95%CI: 0.54–0.96) among older adults (aged ≥ 60 years). The findings of this study indicate that many of the same factors are associated with vaccine hesitancy and being vaccinated multiple times among adults in Japan but that among older individuals, worse mental/psychological health problems may be important for vaccine hesitancy/infrequent vaccine uptake in an age range where the majority of individuals (57.7%) had been vaccinated five times.

Antigenic Characterization of Circulating and Emerging SARS-CoV-2 Variants in the U.S. throughout the Delta to Omicron Waves

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has evolved into numerous lineages with unique spike mutations and caused multiple epidemics domestically and globally. Although COVID-19 vaccines are available, new variants with the capacity for immune evasion continue to emerge. To understand and characterize the evolution of circulating SARS-CoV-2 variants in the U.S., the Centers for Disease Control and Prevention (CDC) initiated the National SARS-CoV-2 Strain Surveillance (NS3) program and has received thousands of SARS-CoV-2 clinical specimens from across the nation as part of a genotype to phenotype characterization process. Focus reduction neutralization with various antisera was used to antigenically characterize 143 SARS-CoV-2 Delta, Mu and Omicron subvariants from selected clinical specimens received between May 2021 and February 2023, representing a total of 59 unique spike protein sequences. BA.4/5 subvariants BU.1, BQ.1.1, CR.1.1, CQ.2 and BA.4/5 + D420N + K444T; BA.2.75 subvariants BM.4.1.1, BA.2.75.2, CV.1; and recombinant Omicron variants XBF, XBB.1, XBB.1.5 showed the greatest escape from neutralizing antibodies when analyzed against post third-dose original monovalent vaccinee sera. Post fourth-dose bivalent vaccinee sera provided better protection against those subvariants, but substantial reductions in neutralization titers were still observed, especially among BA.4/5 subvariants with both an N-terminal domain (NTD) deletion and receptor binding domain (RBD) substitutions K444M + N460K and recombinant Omicron variants. This analysis demonstrated a framework for long-term systematic genotype to antigenic characterization of circulating and emerging SARS-CoV-2 variants in the U.S., which is critical to assessing their potential impact on the effectiveness of current vaccines and antigen recommendations for future updates.

How Technology, Health Information Seeking, and Socioeconomic Factors Are Associated With Coronavirus Disease 2019 Vaccination Readiness in Estonians Over 50 Years?

Despite the proven effectiveness of COVID-19 vaccines in preventing severe illness, many individuals, including older adults who are most susceptible to the virus, have opted against vaccination. Various factors could shape vaccination decisions, including seeking health information (HI). The internet is the primary source of HI today; however, older adults are often referred to as those missing out on digital benefits. The study explores the correlations between information and communication technology (ICT) use, online HI seeking, socioeconomic factors, and COVID-19 vaccination readiness among individuals aged 50 and above in Estonia. The survey data were gathered from 501 people aged 50 and older after the first lockdown in 2020. The outcomes revealed that vaccination readiness positively correlated with factors such as higher educational attainment, greater income, male gender, access to ICT, a readiness to employ digital technologies for health-related purposes, a greater demand for HI, and a higher frequency of seeking it online. There was some discrepancy in the preference of HI sources; for example, vaccination consenters preferred online versions of professional press publications and specific health portals. Based on the findings, it is advisable to encourage older adults to utilize the internet and new technology for health-related purposes. This practice expands the range of information sources available to them, ultimately enabling better decision-making regarding their health behaviors.

Longitudinal study of immunity to SARS-CoV2 in ocrelizumab-treated MS patients up to 2 years after COVID-19 vaccination.

(1) To plot the trajectory of humoral and cellular immune responses to the primary (two-dose) COVID-19 mRNA series and the third/booster dose in B-cell-depleted multiple sclerosis (MS) patients up to 2 years post-vaccination; (2) to identify predictors of immune responses to vaccination; and (3) to assess the impact of intercurrent COVID-19 infections on SARS CoV-2-specific immunity. Sixty ocrelizumab-treated MS patients were enrolled from NYU (New York) and University of Colorado (Anschutz) MS Centers. Samples were collected pre-vaccination, and then 4, 12, 24, and 48 weeks post-primary series, and 4, 12, 24, and 48 weeks post-booster. Binding anti-Spike antibody responses were assessed with multiplex bead-based immunoassay (MBI) and electrochemiluminescence (Elecsys®, Roche Diagnostics), and neutralizing antibody responses with live-virus immunofluorescence-based microneutralization assay. Spike-specific cellular responses were assessed with IFNγ/IL-2 ELISpot (Invitrogen) and, in a subset, by sequencing complementarity determining regions (CDR)-3 within T-cell receptors (Adaptive Biotechnologies). A linear mixed-effect model was used to compare antibody and cytokine levels across time points. Multivariate analyses identified predictors of immune responses. The primary vaccination induced an 11- to 208-fold increase in binding and neutralizing antibody levels and a 3- to 4-fold increase in IFNγ/IL-2 responses, followed by a modest decline in antibody but not cytokine responses. Booster dose induced a further 3- to 5-fold increase in binding antibodies and 4- to 5-fold increase in IFNγ/IL-2, which were maintained for up to 1 year. Infections had a variable impact on immunity. Humoral and cellular benefits of COVID-19 vaccination in B-cell-depleted MS patients were sustained for up to 2 years when booster doses were administered.

Distinct T cell responsiveness to different COVID-19 vaccines and cross-reactivity to SARS-CoV-2 variants with age and CMV status

IntroductionAccumulating evidence indicates the importance of T cell immunity in vaccination-induced protection against severe COVID-19 disease, especially against SARS-CoV-2 Variants-of-Concern (VOCs) that more readily escape from recognition by neutralizing antibodies. However, there is limited knowledge on the T cell responses across different age groups and the impact of CMV status after primary and booster vaccination with different vaccine combinations. Moreover, it remains unclear whether age has an effect on the ability of T cells to cross-react against VOCs.MethodsTherefore, we interrogated the Spike-specific T cell responses in healthy adults of the Dutch population across different ages, whom received different vaccine types for the primary series and/or booster vaccination, using IFNɣ ELISpot. Cells were stimulated with overlapping peptide pools of the ancestral Spike protein and different VOCs.ResultsRobust Spike-specific T cell responses were detected in the vast majority of participants upon the primary vaccination series, regardless of the vaccine type (i.e. BNT162b2, mRNA-1273, ChAdOx1 nCoV-19, or Ad26.COV2.S). Clearly, in the 70+ age group, responses were overall lower and showed more variation compared to younger age groups. Only in CMV-seropositive older adults (>70y) there was a significant inverse relation of age with T cell responses. Although T cell responses increased in all age groups after booster vaccination, Spike-specific T cell frequencies remained lower in the 70+ age group. Regardless of age or CMV status, primary mRNA-1273 vaccination followed by BNT162b2 booster vaccination showed limited booster effect compared to the BNT162b2/BNT162b2 or BNT162b2/mRNA-1273 primary-booster regimen. A modest reduction in cross-reactivity to the Alpha, Delta and Omicron BA.1, but not the Beta or Gamma variant, was observed after primary vaccination.DiscussionTogether, this study shows that age, CMV status, but also the primary-booster vaccination regimen influence the height of the vaccination-induced Spike-specific T cell response, but did not impact the VOC cross-reactivity.

Accelerate vaccine development using seamless phase 2/3 trial designs

ABSTRACT Background Traditional vaccine development, often a lengthy and costly process of three separated phases. However, the swift development of COVID-19 vaccines highlighted the critical importance of accelerating the approval of vaccines. This article showcases a seamless phase 2/3 trial design to expedite the development process, particularly for multi-valent vaccines. Research Design and Methods This study utilizes simulation to compare the performance of seamless phase 2/3 design with that of conventional trial design, specifically by re-envisioning a 9-valent HPV vaccine trial. Across three cases, several key performance metrics are evaluated: overall power, type I error rate, average sample size, trial duration, the percentage of early stop, and the accuracy of dose selection. Results On average, when the experimental vaccine was assumed to be effective, the seamless design that performed interim analyses based solely on efficacy saved 555.73 subjects, shortened trials by 10.29 months, and increased power by 3.70%. When the experimental vaccine was less effective than control, it saved an average of 887.73 subjects while maintaining the type I error rate below 0.025. Conclusion The seamless design proves to be a compelling strategy for vaccine development, given its versatility in early stopping, re-estimating sample sizes, and shortening trial durations.

COVID-19 patient profiles over four waves in Barcelona metropolitan area: A clustering approach.

Identifying profiles of hospitalized COVID-19 patients and explore their association with different degrees of severity of COVID-19 outcomes (i.e. in-hospital mortality, ICU assistance, and invasive mechanical ventilation). The findings of this study could inform the development of multiple care intervention strategies to improve patient outcomes. Prospective multicentre cohort study during four different waves of COVID-19 from March 1st, 2020 to August 31st, 2021 in four health consortiums within the southern Barcelona metropolitan region. From a starting point of over 292 demographic characteristics, comorbidities, vital signs, severity scores, and clinical analytics at hospital admission, we used both clinical judgment and supervised statistical methods to reduce to the 36 most informative completed covariates according to the disease outcomes for each wave. Patients were then grouped using an unsupervised semiparametric method (KAMILA). Results were interpreted by clinical and statistician team consensus to identify clinically-meaningful patient profiles. The analysis included nw1 = 1657, nw2 = 697, nw3 = 677, and nw4 = 787 hospitalized-COVID-19 patients for each of the four waves. Clustering analysis identified 2 patient profiles for waves 1 and 3, while 3 profiles were determined for waves 2 and 4. Patients allocated in those groups showed a different percentage of disease outcomes (e.g., wave 1: 15.9% (Cluster 1) vs. 31.8% (Cluster 2) for in-hospital mortality rate). The main factors to determine groups were the patient's age and number of obese patients, number of comorbidities, oxygen support requirement, and various severity scores. The last wave is also influenced by the massive incorporation of COVID-19 vaccines. Our study suggests that a single care model at hospital admission may not meet the needs of hospitalized-COVID-19 adults. A clustering approach appears to be appropriate for helping physicians to differentiate patients and, thus, apply multiple care intervention strategies, as another way of responding to new outbreaks of this or future diseases.

Multisystem inflammatory syndrome in children: A review.

To comprehensively review the literature on multisystem inflammatory syndrome in children (MIS-C). Narrative review of relevant studies published between April 2020 and January 2024. MIS-C is a SARS-CoV-2-related hyperinflammatory syndrome developing 2-6 weeks after COVID-19 in genetically susceptible individuals. Persisting fever, mucocutaneous manifestations, GI and cardiac involvement, together with lymphopenia and elevated inflammatory and cardiac markers are the main clinical features. It is believed to recognise some pathogenetic and clinical overlap with Kawasaki disease. New case definitions have been proposed after an assessment of the diagnostic performance of existing criteria; epidemiological criterion is however progressively losing its usefulness as the pandemic turns into an endemic and in the areas with the highest rates of COVID-19 vaccination. Current guidelines recommend both intravenous immunoglobulin and glucocorticoids in the first-line immunomodulatory treatment, mainly based on comparative retrospective cohorts; the actual role of biologics remains to be adequately established. Strict follow-up is mandatory, especially for those with severe cardiac involvement, as longitudinal studies evaluate the long-term evolution of cardiac damage. In this paper, we review the epidemiological, pathogenetic, clinical and prognostic features of MIS-C, and outline the main questions which still remain unanswered after more than 3 years of research.

Long-term stability and immunogenicity of lipid nanoparticle COVID-19 mRNA vaccine is affected by particle size

ABSTRACT Messenger ribonucleic acid (mRNA) technology has been rapidly applied for the development of the COVID-19 vaccine. However, naked mRNA itself is inherently unstable. Lipid nanoparticles (LNPs) protect mRNAs from extracellular ribonucleases and facilitate mRNA trafficking. For mRNA vaccines, antigen-presenting cells utilize LNPs through uptake to elicit antigen-specific immunity. There are reports on the impact of various physical characteristics of LNPs, particularly those with sizes less than 200 nm, especially 50 to 150 nm, on the overall stability and protective efficacy of mRNA vaccines. To address this, a single change in the size of LNPs using the same mRNA stock solution was assessed for the physicochemical characterization of the resulting mRNA-LNPs vaccine, along with the evaluation of their protective efficacy. Particles of smaller sizes generally disperse more effectively in solutions, with minimized occurrence of particle precipitation and aggregation. Here, we demonstrate that the vaccine containing 80–100 nm mRNA-LNPs showed the best stability and protection at 4°C and −20°C. Furthermore, we can conclude that freezing the vaccine at −20°C is more appropriate for maintaining stability over the long term. This effort is poised to provide a scientific basis for improving the quality of ongoing mRNA vaccine endeavors and providing information on the development of novel products.

Impact of Vaccination Status on Outcome of Patients With COVID-19 and Acute Ischemic Stroke Undergoing Mechanical Thrombectomy.

Data on impact of COVID-19 vaccination and outcomes of patients with COVID-19 and acute ischemic stroke undergoing mechanical thrombectomy are scarce. Addressing this subject, we report our multicenter experience. This was a retrospective analysis of patients with COVID-19 and known vaccination status treated with mechanical thrombectomy for acute ischemic stroke at 20 tertiary care centers between January 2020 and January 2023. Baseline demographics, angiographic outcome, and clinical outcome evaluated by the modified Rankin Scale score at discharge were noted. A multivariate analysis was conducted to test whether these variables were associated with an unfavorable outcome, defined as modified Rankin Scale score >3. A total of 137 patients with acute ischemic stroke (48 vaccinated and 89 unvaccinated) with acute or subsided COVID-19 infection who underwent mechanical thrombectomy attributable to vessel occlusion were included in the study. Angiographic outcomes between vaccinated and unvaccinated patients were similar (modified Thrombolysis in Cerebral Infarction ≥2b: 85.4% in vaccinated patients versus 86.5% in unvaccinated patients; P=0.859). The rate of functional independence (modified Rankin Scale score, ≤2) was 23.3% in the vaccinated group and 20.9% in the unvaccinated group (P=0.763). The mortality rate was 30% in both groups. In the multivariable analysis, vaccination status was not a significant predictor for an unfavorable outcome (P=0.957). However, acute COVID-19 infection remained significant (odds ratio, 1.197 [95% CI, 1.007-1.417]; P=0.041). Our study demonstrated no impact of COVID-19 vaccination on angiographic or clinical outcome of COVID-19-positive patients with acute ischemic stroke undergoing mechanical thrombectomy, whereas worsening attributable to COVID-19 was confirmed.

Trends in Intention to Take the Second Booster COVID-19 Vaccination and Associated Factors in China: Serial Cross-Sectional Surveys

Background: The escalating complexity of the COVID-19 epidemic underscores the need for heightened attention to booster vaccinations. This study aims to examine the changing trend in the public’s intention to receive the second COVID-19 booster vaccination over time and the associated factors following the COVID-19 policy optimization in China. Method: Eight cross-sectional surveys utilizing SMS questionnaire links were conducted in Guangzhou, China, from December 2022 to April 2023. The Mann–Kendall test was employed to analyze the trend in intentions to receive the second booster vaccination across the survey time. Adjusted and multivariate logistic analyses were used to analyze the factors associated with vaccination intention. Parallel analyses were performed for two subgroups with different COVID-19 infection statuses. Results: A total of 9860 respondents were surveyed in the eight rounds, of which 8048 completed the first booster vaccination and were included in the analysis. The overall COVID-19 infection rate was 60.0% (4832/8048), while the overall vaccination intention was 72.2% (5810/8048) among respondents. The vaccination intention exhibited a significant declining trend over time, decreasing from 81.5% in December 2022 to 52.2% in April 2023. An adjusted logistic regression analysis revealed that anxiety and depression were negatively associated with an intention to receive the second booster vaccination, while COVID-19-related preventive behaviors and a high engagement in COVID-19-related information were positively associated with an intention to receive the second booster vaccination. A subgroup analysis revealed that the association between psychological and behavioral characteristics and vaccination intention remained relatively stable among individuals with different histories of COVID-19 infections. Conclusion: There was a significant decline in the intention to receive the second booster vaccination following the optimization of the COVID policy in China. Our findings emphasize the urgency of the second booster vaccination and provide a foundation for the development of tailored interventions to enhance and sustain vaccination intention among the public.

Patient Outcomes and Healthcare Practices Before and After COVID-19 Vaccination: A Comprehensive Analysis

Abstract: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) unleashed a global pneumonia pandemic, causing significant harm to both physical and mental health. It emphasized the urgency for specialized therapies and protective measures. Approaches, including immunotherapy, antiviral drugs, and lifestyle improvements, like diet and exercise, have shown promise in controlling viral spread before widespread vaccination. However, COVID-19 vaccinations, while critical for reducing disease severity, have been associated with potential side effects, including transient cognitive impairment, rare renal disorders, physiologic anomalies, and dermatological reactions. The scientific community continues to rigorously study these issues to ensure the safety and efficacy of vaccination programs and to address the multifaceted impact of the pandemic.

Science of psychological phenomena and their testing.

There is no crisis of replication and generalizability in psychological science, only misunderstanding or forgetting the fundamental nature of psychological phenomena and resultant implications for empirical testing. Stability-variability is the central feature of every psychological phenomenon, meaning that brain-mind interactions can only create stable patterns from which there will always be deviations. Psychological phenomena are not comparable to COVID-19 vaccines that were very effective (95%) initially for almost everyone for a long time. Replications cannot be the gatekeepers of scientific psychological knowledge, only constructive additions and explorations contributing to theory development and measurement improvement. Once a logically justified and theoretically well-developed hypothesis is presented, the phenomenon exists as long as one of the following conditions is true: (1) it has not been shown logically that the phenomenon cannot exist or (2) it has not been shown empirically that the phenomenon does not exist. Like in physics and other sciences, generalization to theory is critical in psychological science, but less important relative to hypothetical (phantom) populations. Initial COVID-19 vaccines were effective because they worked for the right theoretical reason, the mRNA mechanism. This central principle holds true for psychological phenomena as well, with findings generalizing to the theoretical explanation regarding the presence and manifestations of behaviors brought about by the brain-mind interactions, or stated differently, generalization of psychological phenomena to specific behaviors and under specific conditions as proposed by the theory. Instead of the narrow focus on generalization to hypothetical populations, psychological phenomena and associated generalization could more productively be examined from the nine proposed perspectives.

Learning Lessons from the COVID-19 Pandemic-A Qualitative Assessment of the Experiences of Pregnant Latinas Infected with COVID-19 and Their Perspectives on Vaccination.

To examine the experiences of pregnant Hispanic/Latine people with COVID-19, as well as their perspectives on COVID-19 vaccination in pregnancy. We interviewed birthing parents who received care from a teaching hospital in California and tested positive for COVID-19 during pregnancy or delivery. We analyzed transcripts using the constant comparative method for analyzing data to using a phenomological epidemiological approach. We used root cause analysis to identify consistent themes across interviews and assess relationships between social determinants of health and COVID-19 infectivity. We interviewed 14 women from November 2021 to June 2022. Participants reported COVID-19 adversely impacted their clinical care and well-being during pregnancy or postpartum. Impacts among Spanish-speaking participants included unexpected financial hardships, challenges navigating in-patient experiences, and difficulty securing reliable childcare. While most participants were at least partially vaccinated, participants also described doubts and concerns about the vaccine. Our findings suggest that Spanish-speaking Hispanic/Latine patients could benefit from receiving more information about COVID-19 in pregnancy from their healthcare providers. Leveraging familial and social networks, providing reliable information in people's preferred language, and increasing communication through trusted partners may also help combat vaccine hesitancy.

Long-term complications of COVID-19 in Jordan: A study on persisting symptoms and management

BackgroundThe COVID-19 pandemic has led to the emergence of a significant health issue – post-COVID-19 syndrome (PCS), characterized by long-term complications in survivors. This study focused on Jordan to assess the prevalence of PCS, associated symptoms, and potential influencing factors, including vaccine types. MethodsA cross-sectional study recruited 500 participants from various regions in Jordan. Structured questionnaires were used to collect data on participant demographics, symptoms, and treatment approaches. The study also investigated the relationship between specific symptoms and different COVID-19 vaccines. ResultsThe majority of participants were aged 25–55 years, well-educated, and had chronic comorbidities. Notable sensory complications included anosmia and dysgeusia, while psychiatric symptoms and reduced sexual desire were also prevalent. Interestingly, Pfizer® and Sinopharm® vaccines were linked to distinct symptom patterns. Participants pursued various treatments, including pharmacological and non-pharmacological options such as honey and vitamins. Relatives, friends, and pharmacists were the primary sources of information for participants. ConclusionThe study underscores the significant burden of PCS in Jordan and highlights the necessity for tailored interventions, mental health support, and effective communication strategies in post-COVID-19 care. The findings contribute to a comprehensive understanding of PCS and offer valuable guidance for healthcare systems in addressing the evolving healthcare needs of COVID-19 survivors.
