Usability of a Web-Based App for Increasing Adolescent Vaccination in Primary Care Settings: Think-Aloud and Survey Assessment.

In the United States, only 58% of teens receive the recommended 2 doses of the human papillomavirus vaccine by 15 years of age. Overcoming vaccine hesitancy often requires effective communication between clinicians and parents to address specific concerns. To support this, we developed ProtectMe4, a multilevel, theory-informed web-based intervention designed to address parents' vaccine-related questions and assist clinicians in discussing vaccine concerns for 4 adolescent vaccines. This study aims to evaluate the usability of ProtectMe4 in routine care settings across 3 pediatric primary care clinics. Specifically, the study aims to (1) observe the proposed workflow in practice, (2) identify usability issues experienced by parents and clinicians, and (3) assess the perceptions of both parents and clinicians regarding the app's usability. On designated days in 2020 and 2021, the study team recruited parents of 11- to 12-year-old patients attending appointments with participating clinicians. We conducted think-aloud assessments during routine care visits and administered a usability survey after participants used the app. For parents, we simultaneously video-recorded the app screens and audio-recorded their commentary. For clinicians, observational notes were taken regarding their actions and comments. Timings recorded within the app provided data on the length of use. We reviewed the recordings and notes to compile a list of identified issues and calculated the frequencies of survey responses. Out of 12 parents invited to use the app, 9 (75%) participated. Two parents who were invited outside of the planned workflow, after seeing the clinician, refused to participate. For the parents whose child's vaccination record was identified by the app, the median time spent using the app was 9 (range 6-28) minutes. Think-aloud assessment results for parents were categorized into 2 themes: (1) troubleshooting vaccine record identification and (2) clarifying the app content and purpose. Among the 8 parents who completed the survey, at least 75% (6/8) agreed with each acceptability measure related to user satisfaction, perceived usefulness, and acceptance. These parents' children were patients of 4 of the 7 participating clinicians. Consistent with the planned workflow, clinicians viewed the app before seeing the patient in 4 of 9 (44%) instances. The median time spent on the app per patient was 95 (range 5-240) seconds. Think-aloud assessment results for clinicians were grouped into 2 themes: (1) trust of app vaccine results and (2) clarifying the app content. On the survey, clinicians were unanimously positive about the app, with an average System Usability Scale score of 87.5 (SE 2.5). This mixed methods evaluation demonstrated that ProtectMe4 was usable and acceptable to both parents and clinicians in real-world pediatric primary care. Improved coordination among clinic staff is needed to ensure the app is consistently offered to patients and reviewed by clinicians before seeing the patient.

Vaccine Confidence and Coverage among Medical Students at a Federal University in Brazil.

Declining vaccination coverage (VC) and vaccine hesitancy among medical students are global challenges. These challenges reflect individual and logistical barriers to a sufficient adherence toward essential vaccines for healthcare professionals, as well as presenting a need for educational strategies during undergraduate training. This is a prospective study for evaluating VC rates, sociodemographic associations, and the vaccine confidence among medical students at a federal university in Brazil. The data collection included questionnaires and individual analyses of the participants' vaccination records. A total of 237 medical students from all six years of an undergraduate program participated, of whom 124 (52.3%) had a vaccination record. Although the majority considered the vaccines to be "Completely Safe" (86.9%), the VC rates for complete vaccination schedules were relatively low, ranging from 87.9% (hepatitis B vaccine) to 3.2% (meningococcal B vaccine), including the vaccines from the National Immunization Program (NIP) and the private sector. Higher VC rates were found to occur among students in the final years of their undergraduate studies, in those from families with higher monthly incomes, and those from private secondary schools. Given the low VC rates among medical students, other factors in addition to vaccine confidence may be determinants, thus highlighting the importance of reviewing policies for the inclusion of priority groups in the NIP and in implementing educational interventions during undergraduate training.

Hypertension management and outcomes during the covid-19 pandemic: diagnosis, blood pressure telemonitoring use and mortality

Abstract Introduction The effects of COVID-19 on people with hypertension are poorly understood, but potentially severe both due to increased risk of cardiovascular events post covid (1) and by altering the way people accessed healthcare (2). This study aimed to explore the immediate impact of COVID-19 on the hypertensive population in Scotland. Methods The study used linked routine clinical data. Hypertensive patients from five NHS Scotland Health Boards were identified through the Prescribing Information System (PIS) between March 2019 and February 2021. Linked data included Blood Pressure (BP) telemonitoring data from the Connect Me BP service, outcome data (cardiovascular events and mortality) from Scottish Morbidity Records, and National Records of Scotland COVID-19 testing and vaccination records from Public Health Scotland (PHS). Follow up was until February 2022. EDRIS, the research arm of PHS, linked and pseudonymised the data and transferred it to the secure national safe haven analysis platform for access by the research team. The study was approved by the Public Benefit and Privacy Panel for Health and Social Care. Results Almost 450,000 people with hypertension were identified across the whole adult age range, 52% male. Of those, 89% had been diagnosed prior to the study. New diagnoses dropped by over 50% during the first year of the COVID-19 pandemic. The use of long term BP telemonitoring increased rapidly during the pandemic from 5000 to over 10,000. Overall mortality was over 8%. Mortality rates showed a similar pattern to the general population during the pandemic and remained above pre-pandemic levels until the end of the follow up period in February 2022. Discussion BP telemonitoring supported healthcare delivery at a time when normal services were severely disrupted due to COVID-19. However the data suggests that there may be an increase in the number of people with undiagnosed hypertension with associated raised cardiovascular risk. Mortality in this population was increased by the COVID-19 pandemic and remained above pre-pandemic levels.

Challenges in assessing the immunization status of adults in Germany—lessons from a population-based VACCELERATE survey on polio vaccination

PurposeConsidering the re-emergence of poliomyelitis (PM) in non-endemic regions, it becomes apparent that vaccine preventable diseases can rapidly develop epi- or even pandemic potential. Evaluation of the current vaccination status is required to inform patients, health care providers and policy makers about vaccination gaps.MethodsBetween October 28 2022 and November 23 2022, 5,989 adults from the VACCELEREATE Volunteer Registry completed an electronic case report form on their previous PM vaccine doses including number, types/-valencies and the time of administration based on their vaccination records. A uni-/multivariable regression analysis was performed to assess associations in participant characteristics and immunization status.ResultsAmong German volunteers (n = 5,449), complete PM immunization schedule was found in 1,981 (36%) participants. Uncertain immunization, due to unknown previous PM vaccination (n = 313, 6%), number of doses (n = 497, 9%), types/-valencies (n = 1,233, 23%) or incoherent immunization schedule (n = 149, 3%) was found in 40% (n = 2,192). Out of 1,276 (23%) participants who reported an incomplete immunization schedule, 62 (1%) never received any PM vaccine. A total of 5,074 (93%) volunteers reported having been vaccinated at least once and 2,087 (38%) indicated that they received vaccination within the last ten years. Female sex, younger age, as well as availability of first vaccination record were characteristics significantly associated with complete immunization (p < 0.001).ConclusionFull PM immunization schedule was low and status frequently classified as uncertain due to lack of details on administered doses. There is an obviousneed for improved recording to enable long-term access to detailed vaccination history in the absence of a centralized immunization register.

Dynamics of Timely Vaccination Among Tender-Age Infants in two Subjects of Russian Federation with the Lowest Immunization Coverage in 2020: Serial Cross-Sectional Study

Background. It was revealed in 2020 that immunization of children in decreed times in several subjects of Russian Federation was below the standard level. Therefore, monitoring of timely vaccination in children of these regions was relevant. Objective. The aim of the study is to evaluate changes in the timeliness of vaccination in children of two subjects of Russian Federation with low immunization rates according to 2020 data. Methods. Immunization of children born in 2015–2017 and 2020–2022 were studied according to the form of federal statistical monitoring (FFSM) No. 6 and vaccination record cards (form No. 063/y) obtained from children's polyclinics of the Republic of Bashkortostan (two in 2020 and three in 2023) and the Republic of Sakha (Yakutia) (two in 2020 and four in 2023). The vaccination timeliness among children against infections from the national immunization schedule (NIS) list was determined. The timeliness of vaccination was evaluated by the proportion of children who received the required number of vaccine doses against each of the infection from the NIS list by the decreed age among all persons of the decreed age. Results. Data from 998 records was analyzed. The increase in timely vaccination against all vaccine-controlled infections in children was revealed. The proportion of children vaccinated according to the NIS has increased by 1.5–4 times. Timely vaccination of 95% children in the decreed age (by FFSM No. 6) was achieved in the Republic of Sakha (Yakutia) against tuberculosis, hepatitis B, measles, rubella, and mumps, and in the Republic of Bashkortostan against measles, rubella, and mumps. The increase in the multivalent vaccines’ usage and simultaneous administration of several vaccines has been discovered. Conclusion. Monitoring the level of documented immunization and timely vaccination in children allows effectively control routine immunization quality. Implementation of multivalent vaccines and simultaneous administration of several vaccines in routine immunization provides radical change in the vaccination rate in pediatric population.

Awareness and utilization of mother and child protection (MCP) card among mothers attending immunization OPD: An urban health centre-based cross-sectional study.

The MCP card is used as a tool for pregnant women, young mothers and family members to learn about various types of services which they should assess and utilize. The study was undertaken to see the awareness about MCP card and its components among beneficiaries in urban slum area. This is a cross-sectional observational study done in urban slum immunization OPD with a sample size of 226. Convenient sampling method was used to select the samples. Mothers consenting and willing to participate in the study were enrolled. Observed that the MCP card was issued to majority participants at the time of baby immunization (44.15%), followed by at time of delivery (31.4%) and least number received it at the time of pregnancy registration (24.34%). It is also observed that only 53.54%(121) women had read the card while the remaining didn't. Majority thought the primary use of MCP card was vaccination record (91.5%), followed by information tool (52.%). It is observed that knowledge regarding pregnancy care and its related complications leads to better utilization of ANC services. As observed in the present study a sizeable proportion of populations doesn't even read the card, and among those who read it the level of knowledge isn't satisfactory, many use the card as a vaccination record but still the awareness about various vaccines among the beneficiaries remains low.

A Digital Vaccination Pass Using Fast Healthcare Interoperability Resources: A Proof of Concept

The traditional manual recording of vaccination records in Germany faced challenges during the COVID-19 pandemic, prompting the introduction of a COVID smartphone app with QR codes. However, this solution brought new challenges, emphasizing the need for a centrally managed European digital vaccination record for efficiency and validity. This study assesses the feasibility of using the HL7 FHIR standard in the healthcare industry for implementing a digital vaccination pass management and monitoring system. The system aims to offer convenience and improved efficiency for both patients and healthcare providers while promoting interoperability with other healthcare systems. To this end, we developed a prototype using modern technologies, such as React, Quarkus, and Keycloak. Results indicate potential benefits for patients and healthcare providers, offering access to immunization records, personalized recommendations, and streamlined management. However, integrating nuanced vaccination processes into the standardized FHIR system requires custom extensions, which might hinder interoperability. Manual data entry and the integration of an identity provider present further obstacles in industry scenarios. Despite these challenges, this study suggests that implementing HL7 FHIR can enhance efficiency, data accessibility, and accuracy in the vaccination process, supporting broader digitization efforts in the German healthcare system and beyond.

Coverage, mapping and barriers to complete vaccination for age among children under 5 years in 2021: case of Adjara-Hounvè and Ahouicodji villages in southern Benin

Vaccination is a protective measure against infectious diseases and remains one of the best investments in public health. Some African countries are still struggling to reach the required child immunization coverage. Several factors are responsible for limiting immunization coverage. Most of the factors considered to limit immunization coverage are related to the health system. In addition, inaccessibility to care, especially during the critical period of the Covid-19 pandemic, greatly reduced vaccination coverage rates. In Benin, several vaccines are included in the Expanded Programme on Immunization or are administered as part of routine immunization. However, cases of non-compliance with the vaccine and persistent flaccid paralysis are still recorded in the commune of Ouidah in southern Benin. The aim of this study was to investigate the coverage and factors associated with full immunization for age in children aged 0-5 years. A cross-sectional survey was conducted from August to October 2021 in two villages (Adjara-Hounvè and Ahouicodji) in southern Benin. All the households were included. The survey regarded children under 5 for whom a vaccination record was presented. A couple child/mother was recruited after informed consent of the mother and her child. An univariate analysis followed by a multivariate analysis was performed by using a logistic regression model to identify the variables that influence vaccine completeness. Spatial description of vaccine completeness was performed using the kriging method using ArcGIS 10.8 mapping software. Results. Of the 414 mothers surveyed, 57.49% had an immunization card, from which information was collected. Of the 238 children recruited, 141 were in Adjara-Hounvè and 97 in Ahouicodji. Of the 238 children with an immunization card, 20.6% were fully immunized for their age. All children received Baccille Calmette Guérin vaccine at birth. Since poliomyelitis, pentavalent, pneumococcal conjugate, and rotavirus are three-dose vaccines, the percentage of children who received these vaccines decreased as the number of doses increased: 96.6%, 88.2%, 78.1% and 72.3% for the four doses of polio respectively. According to 53.4% of the respondents the reception at the vaccination site was poor, and according to 70.3% of them waiting time for vaccination sessions was long. Several reasons justified the absence of complete vaccination for the age of the children: vaccination site too far from the place of residence (59.54%), lack of financial means (29.78%) and the mother's ignorance (12.76%). Education level "primary" vs "none" (ORa = 3.32; CI95% 1.07-10.25), occupation "health staff" vs "housewife" (ORa = 21.18; CI95% 3.07-145.94), mothers' knowledge of Expanded Programme on Immunization diseases (ORa = 2, 20; CI95% 1.03-4.68) and children's age 0-2 months vs ≥ 16 months (ORa = 8.53; CI95% 2.52-28.85) and 9-15 months vs ≥ 16 months (ORa = 2.99; CI95% 1.24-7.23) increased complete immunization status for age. The homogeneity of behaviour related to age-complete immunization coverage in children under 5 years was evident at mapping. Age-complete immunization coverage in children under 5 years of age is very low, with a spatial homogeneity in community immunization uptake behaviour. Age-complete immunization coverage is an innovative indicator that can contribute to achieving age-specific immunization targets.

Retrospective study about clinical severity and epidemiological analysis of the COVID-19 Omicron subvariant lineage-infected patients in Hohhot, China

BackgroundFear of a global public health issue and fresh infection wave in the persistent COVID-19 pandemic has been enflamed by the appearance of the novel variant Omicron BF.7 lineage. Recently, it has been seeing the novel Omicron subtype BF.7 lineage has sprawled exponentially in Hohhot. More than anything, risk stratification is significant to ascertain patients infected with COVID-19 who the most need in-hospital or in-home management. The study intends to understand the clinical severity and epidemiological characteristics of COVID-19 Omicron subvariant BF.7. lineage via gathering and analyzing the cases with Omicron subvariant in Hohhot, Inner Mongolia. MethodsBased upon this, we linked variant Omicron BF.7 individual-level information including sex, age, symptom, underlying conditions and vaccination record. Further, we divided the cases into various groups and assessed the severity of patients according to the symptoms of patients with COVID-19. Clinical indicators and data might help to predict disadvantage outcomes and progression among Omicron BF.7 patients.ResultsIn this study, in patients with severe symptoms, some indicators from real world data such as white blood cells, AST, ALT and CRE in patients with Omicron BF.7 in severe symptoms were significantly higher than mild and asymptomatic patients, while some indicators were significantly lower.ConclusionsAbove results suggested that the indicators were associated with ponderance of clinical symptoms. Our survey emphasized the value of timely investigations of clinical data obtained by systemic study to acquire detailed information.

Vaccinations in patients diagnosed with an autoimmune disorder receiving an immunosuppressive agent: a best practice implementation project.

Immunosuppressed patients face increased health risks due to infections such as influenza or COVID-19. Scientific evidence supports improved health-related outcomes in this patient population, such as reduced hospitalizations, with up-to-date vaccinations. The project setting, a community-based rheumatology clinic, did not have a vaccination record specific to the needs of immunosuppressed patients, which may lead to a suboptimal immunization status in these patients. This project aimed to promote evidence-based practices regarding the use of vaccinations in patients diagnosed with autoimmune disorders receiving immunosuppressive agents. This project used the JBI evidence implementation framework to promote best practices regarding vaccination. Two audit criteria were identified using a JBI Evidence Summary. Baseline audits identified gaps between the evidence and current practice. Barriers to best practice were then identified, and strategies implemented. Post-implementation audits measured changes in compliance. Baseline audits revealed 67% compliance with the two best practices. Barriers included a lack of provider awareness of the current vaccination recommendations for immunosuppressed patients and a lack of customizable vaccine records. Strategies to address these barriers included educating providers about current national vaccination recommendations and implementing a new patient vaccination history intake form. Post-implementation audits revealed 83% compliance, with a 16% increase from baseline. This evidence-based implementation project enhanced best practices by educating providers and implementing an updated patient vaccination history form. Recommendations include the improved compliance with the use of the new form and to assess the effectiveness and usability of a customizable electronic form that interfaces with the clinic's electronic medical records.

Seroconversion and Prevalence of Hepatitis B Surface Antigen among Vaccinated Health Care Workers in Ashanti Region, Ghana.

Health care workers (HCWs) constantly stand at a high risk of exposure to the hepatitis B virus because of the nature of their work. Hence, it is mandatory for HCWs to undergo hepatitis B vaccination. However, most HCWs in Ghana do not check their HBsAb titre after completion of their primary vaccination. This study assessed the prevalence of HBsAg and the seroconversion rate among vaccinated health care workers in the Ashanti Region, Ghana. A semistructured open-ended questionnaire was pretested and administered to 424 HCWs. Two (2) ml of blood was drawn and qualitative analyses (HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb) were done on the blood samples. Samples that tested positive to HBsAb were quantified using ELISA. Data obtained were analysed using GraphPad Prism 9. Out of the 424 study participants, 271 (63.9%) were females and 153 (36.1%) were males. Seroconversion (≥1 mIU/mL) and seroprotection (≥10 mIU/mL) through vaccination only among study participants were 67.5% (n/N = 286/424) and 58.0% (n/N = 246/424), respectively. Prevalence of hepatitis B viral infection was 2.4% (n/N = 10/424). Anti-HBc seropositivity was 13.2%, and anti-HBs seronegativity was 24.1%. 2.4% (n/N = 10/424) of study participants were negative to HBsAg but positive to HBcAb. In addition, 8.5% (n/N = 36/424) of the study participants were seroprotected due to exposure and recovery from previous HBV infection. Age, the number of doses received, taking a booster dose, and keeping a vaccination record card were significant factors influencing seroconversion status. This study reaffirms the need for HCWs to undergo a supervised primary hepatitis B vaccination course. Postvaccination serological testing should be done for all HWCs to confirm immunity and reduce their chances of contracting HBV infection.

The Influence of Introducing Free Vaccination against Streptococcus pneumoniae on the Uptake of Recommended Vaccination in Poland.

Since 2017, pneumococcal vaccination has evolved from a recommended chargeable vaccination to a mandatory, and therefore free, vaccination for all children. While a 10-valent vaccine is commonly used, parents have the option to use a 13-valent vaccine for a fee. This study aimed to investigate whether and how the introduction of free pneumococcal vaccination affected the uptake of recommended vaccination and to assess the association of chargeable pneumococcal vaccination with recommended vaccination. Data from 1595 vaccination record cards kept by six primary care clinics in urban and rural areas of Poland were collected and analyzed for children born between 2015 and 2018. Belonging to the clinic and the year of birth were the only inclusion criteria. Following the introduction of free universal pneumococcal vaccination, more children were vaccinated with the recommended vaccination (61.2% vs. 66.6%, p = 0.026). The most significant change was in vaccination against rotavirus (48.5% vs. 54.4%, p = 0.018) and against meningococcal B bacteria (4.8% vs. 17.0%, p < 0.001). Children who received chargeable pneumococcal vaccination were also significantly more likely to be vaccinated with recommended vaccines (54.6% vs. 75.9%, p < 0.001). In particular, this was the case for multivalent vaccinations-against rotavirus, chickenpox, and meningococcal C bacteria. Reducing the impact of the economic factor, for example, by introducing free vaccinations, should have a positive impact on the uptake of other recommended vaccinations.

Serological and vaccine evaluation for hepatitis B among Community Health Workers.

to identify the vaccination and serological status against hepatitis B among community health workers; to vaccinate against hepatitis B virus and to evaluate the immune response of susceptible workers. phase I, cross-sectional and descriptive study, among community health workers in a capital city of the Midwest region, through a self-administered questionnaire, checking of vaccination cards, and blood collection for testing of serological markers for hepatitis B. Phase II, cohort study carried out in vaccinated non-immune workers identified in phase I. They received one dose of vaccine (challenge dose) and serological testing. a total of 109 workers participated in the study. Most had vaccination record (97; 89.0%) and vaccination completeness (75; 77.3%), while the isolated anti-HBs (Antibodies against hepatitis B virus) marker was detected in 78 (71.6%) workers. The prevalence of hepatitis B virus exposure was 8.2%. Of the ten non-immune vaccinated workers, after challenge dose, one remained susceptible. although most workers are vaccinated and show immunological response to hepatitis B, susceptibility after challenge dose was identified. Therefore, it is necessary to have a surveillance program of the vaccination situation and serological status for this virus, to promote these workers' safety.

1172. Compliance with Human Papillomavirus Vaccination At The HIV Outpatient Program in New Orleans, Louisiana

Abstract Background Guidelines recommend the human papillomavirus (HPV) vaccine for all adults through age 26, shared clinical decision-making for those aged 27 through 45 years who are inadequately vaccinated, and for all people with HIV up to age 45 years. The intent of this study is to evaluate HPV vaccination rates at the HIV Outpatient Program (HOP) at University Medical Center in New Orleans. Methods Immunization records from patients aged 18 through 45 years attending a physician visit in the LSU Infectious Diseases fellows’ HIV primary care clinic at HOP in 2022 were reviewed. The purpose of this project was to assess compliance with HPV vaccination recommendations among the infectious diseases fellows. Results Among patients under age 27, 15 of 21 visits (71%) had completed HPV vaccines series. 4 visits (19%) had incomplete status and 2 visits (10%) did not have any HPV vaccines record. Among patients aged 27 through 45 years, 73 of 194 visits (38%) had completed HPV vaccines series. 34 visits (18%) had partial vaccination records and 87 visits (45%) had no records. Conclusion Vaccination compliance among the LSU ID fellows was less than ideal, only 71% of visits for patient aged up to 27 years attending LSU ID fellows’ clinic had completed HPV vaccine series, compared to the Health People 2020 recommendation of 80%. Only 38% of visits for patients aged 27 through 45 years are fully vaccinated with HPV vaccines. Patients in this age group are often labeled “aged out” for HPV vaccines by health maintenance reminders however, due to having HIV, they are still eligible and should be vaccinated. These results led to the institution of quality improvement project to address HPV vaccinations. This intervention will focus on educating all HOP providers about the vaccination recommendations and updating the health maintenance care gaps reminder in the electronic medical record.

Post COVID19 vaccination burnout?: Providers’ perspectives on patients with lung cancer.

401 Background: Patients with solid cancers undergoing chemotherapy or immunotherapy face increased risk of infections due to their immunosuppression and are recommended to undergo routine vaccination. However, despite increased attention to vaccination with the COVID19 pandemic, vaccination rates remain suboptimal among patients with cancer. Methods: Retrospective chart review was used to determine baseline rates of COVID19, Influenza, and Pneumococcal vaccination among a cohort of newly diagnosed patients with lung cancer at multi-site academic cancer center from 2018-2022 (n = 624). An anonymous survey was distributed to all Hematology-Oncology providers (n = 101) at the same institution with questions on current practice on accessing vaccination records and barriers to vaccinating patients starting chemotherapy and/or immunotherapy. Results: The baseline documented COVID-19 vaccination rate was 29.6%, while the baseline documented influenza and pneumococcal vaccination rates were 27.2% and 1.42%, respectively. Survey response was 32.7% (n = 33). Respondents were 60.0% Female (n = 15), 52.0% 30 - 39 years old (n = 13), 56.0% Attending Physicians (n = 14), 28.0% Fellow Physicians (n = 7), and 16.0% Nurse Practitioners (n = 4). 54.5% and 57.6% of respondents always recommended or discussed COVID19 and influenza vaccination, respectively, with their patients on chemotherapy or immunotherapy regardless of cancer type. 12.1% of respondents always recommended pneumococcal vaccination with their patients. The most common moderate barriers to COVID19 and influenza vaccination were “not having enough time” (COVID19, n = 12, 40.0%), (Influenza, n = 7, 26.9%), and “forgetting to bring up vaccines during the visit” (COVID19, n = 12, 40.0%), (Influenza, n = 9, 34.9%). “Not knowing when to administer the vaccine” was a moderate barrier to pneumococcal vaccination in 53.8% of respondents (n = 14). The most common preferred method for obtaining vaccination record information was through patient interview (n = 14, 63.6%). Similar trends were noted when limited to providers who cared for patients with lung cancer. Conclusions: Patients with lung cancer at this academic medical center were found to have low documented rates for COVID19, influenza, and pneumococcal vaccination. Common barriers in vaccination included lack of time and forgetting to bring up vaccination, but lack of knowledge of vaccination timing was only a significant barrier for pneumococcal vaccination. Improvement initiatives to address these identified factors are forthcoming.

Vaccination against Streptococcus pneumoniae in Children Born between 2015 and 2018 in Poland-How Has the Introduction of Free Compulsory Pneumococcal Vaccination Affected Its Uptake?

Starting from 2017, pneumococcal vaccination was added to the Polish vaccination calendar as mandatory for all children born after 2016. The 10-valent conjugate vaccine was selected as mandatory and therefore free of charge. This paper aims to examine the impact of introducing mandatory vaccination on vaccine uptake. For this purpose, an analysis was conducted for 1595 vaccination record sheets from outpatient clinics in Wrocław and surrounding villages for children born 2015-2018. After the introduction of compulsory vaccination, the percentage of children fully vaccinated against pneumococcus increased (60.4% vs. 84.8%, p < 0.001). A significant decrease in the number of children who did not receive any dose of the vaccine was observed (27.8% to 3.3%, p < 0.001). The introduction of compulsory vaccination did not affect the completion of the pneumococcal schedule (11.8% vs. 11.9%). Compulsory PCV10 vaccination resulted in the less frequent choice of the 13-valent vaccine (72.3% vs. 19.9%, p < 0.001). More children in rural outpatient clinics were vaccinated against pneumococcus compared to urban outpatient clinics (84.8% vs. 70.8%, p < 0.001). The introduction of free pneumococcal vaccination increased the proportion of children vaccinated, although it did not affect the rate of discontinuation of the initiated schedule. In Poland, the increased popularity of the 10-valent vaccine at the expense of the 13-valent one translated into a change in the proportion of pneumococcal serotypes causing invasive pneumococcal disease.
