Project description:BACKGROUND:Understanding reasons for and against vaccination from the parental perspective is critical for designing vaccination campaigns and informing other interventions to increase vaccination uptake in Canada. The objective of this study was to understand maternal vaccination decision making for children. METHODS:Mothers participating in a longitudinal community-based pregnancy cohort, the All Our Babies study in Calgary, Alberta, completed open-ended survey questions providing explanations for the vaccination status of their child by 24?months postpartum. Qualitative responses were linked to administrative vaccination records to examine survey responses and recorded child vaccination status. RESULTS:There were 1560 open-ended responses available; 89% (n?=?1391) provided explanations for vaccinating their children, 5% (n?=?79) provided explanations for not vaccinating/delaying, and 6% (n?=?90) provided explanations for both. Themes were similar for those vaccinating and not vaccinating/delaying; however, interpretations were different. Two broad themes were identified: Sources of influence and Deliberative Processes. Sources of influence on decision making included personal, family, and external experiences. Deliberative Processes included risk, research, effectiveness, and balancing risks/benefits. Under Deliberative Processes, responsibility was a category for those vaccinating; while choice, instrumental/practical, and health issues were categories for those not vaccinating/delaying. Mothers' levels of conviction and motivation provided a Context for understanding their decision making perspectives. CONCLUSIONS:Vaccination decision making is complex and impacted by many factors that are similar but contribute to different decisions depending on mothers' perspectives. The results of this study indicate the need to examine new intervention approaches to increase uptake that recognize and address feelings of pressure and parental commitment to choice.

Project description:BACKGROUND:People with a condition subject to stigmatisation, such as chronic hepatitis B, face the dilemma of whether or not to disclose their status. In Ghana, 12.3% of the adult population has the hepatitis B virus (HBV). One key strategy for breaking the cycle of hepatitis B transmission is the disclosure of hepatitis B status by people with chronic hepatitis B (PWHB). Disclosure can facilitate preventive actions to reduce hepatitis B transmission (e.g., not sharing personal items and avoiding contact with blood and body fluids). Disclosure can also motivate family members of PWHB to get tested, linked to care and clinically managed in order to reduce the progression of hepatitis B to liver cirrhosis and cancer. Given the importance of disclosure, we set out to explore reasons for and against disclosure of chronic hepatitis B status in the Greater Accra and Upper East region of Ghana. METHODS:In this exploratory qualitative study, 18 participants (10 from the Greater Accra region and 8 from the Upper East region) were recruited for semi-structured interviews. Interviews were recorded and transcribed verbatim. Data were then processed using QSR Nvivo version 10.0 and analysed for themes. RESULTS:Participants were selective disclosers, disclosing in some contexts and not in others. Reasons for non-disclosure of chronic hepatitis B status were: 1) fear of stigmatisation and 2) previous negative experiences with disclosure. Reasons for disclosure were: 1) wanting close contacts to get tested or vaccinated, 2) trusting the disclosure target(s), and 3) needing social and/or financial support. CONCLUSIONS:Our findings highlight various reasons for and against disclosure of chronic hepatitis B status in Ghana. Because anticipated, observed, and experienced stigma were important motivations for non-disclosure of chronic hepatitis B status, we recommend the development and implementation of theory and evidence-based stigma reduction interventions that are culturally appropriate, and that prioritize the participation of target populations. We also recommend the provision of counselling and support services that assist PWHB in their disclosure decision-making processes.

Project description:BackgroundHepatitis B imposes a major public health problem with an increased risk of occupational exposure among unvaccinated health care workers. This study was conducted to determine the Hepatitis B vaccination status, along with the knowledge, attitude, and practice regarding Hepatitis B, among preclinical medical students of a medical college in Nepal.Materials and methodsThis descriptive study was conducted among preclinical students of a medical college in Kathmandu, Nepal from 6th July to 14th July 2020. The whole sampling technique was used. Data were collected using a pretested, self-administered questionnaire which was emailed to individuals and analyzed with the statistical package for social sciences version-22.ResultsA total of 181 students participated in the study out of 198, giving a response rate of 91.4%. Among the study participants, only 67 (37%) were fully vaccinated against Hepatitis B while 71 (39.2%) were never vaccinated. For the majority (74.6%) of the non-vaccinated participants, the main reason for not getting vaccination was a lack of vaccination programs. Half the study participants (n = 92, 50.8%) had good knowledge, attitude and practice regarding hepatitis B. The median knowledge, attitude and practice scores towards Hepatitis B were 61.00 (57.00-66.00), 20(18.00-21.00) and 21(19.00-23.00) respectively.ConclusionsThe majority of preclinical medical students were not fully vaccinated against Hepatitis B and only half of them had acceptable knowledge, attitude and practice towards Hepatitis B, which makes them vulnerable to the infection. This might represent the situation of not only Nepal, but also all South Asian countries, and creates concern about whether students take the vaccination programs seriously. Since unavailability of vaccination program is the main cause of non-vaccination, we strongly recommend the provision of the Hepatitis B vaccination program to the preclinical medical students.

Project description:Background:World Health Organization and Centers for Disease Control and Prevention recommend all health professionals to get vaccinated against hepatitis B virus before they start the clinical attachments during their stay in the medical school. However, only 18-39% of healthcare workers in low- and middle-income countries received the vaccine. Therefore, this study aims to determine the attitude and vaccination status of health professionals working at Adama General Hospital and Medical College. Methods:An institution-based cross-sectional study was conducted from December 2016 to February 2017 with 403 health professionals working at Adama General Hospital and Medical College. Data were collected using self-administered questionnaire distributed at the participant's work unit and analyzed using SPSS version 20. Multiple logistic regression analysis was conducted to identify factors that affect the complete vaccination status and p value < 0.05 was considered statistically significant. Result:The prevalence of complete vaccination against hepatitis B virus was 25.6%. The most frequently mentioned reasons for not being vaccinated were high cost of the vaccine (41%) and unavailability of the vaccine (36%). More than three-fourths (77.8%) of study participants strongly agreed that hepatitis B is a major public health threat and there was tendency among participants to believe that their profession will put them at increased risk of acquiring the disease (strongly agreed: 75.9%). Attending infection-prevention training [AOR = 2.3; 95% CI, 1.24-6.31], history of exposure to risky behavior [AOR = 5.5; 95% CI, 2.86-9.29], and long years of work experience [AOR = 3.1; 95% CI, 1.98-5.24] were statistically significant with complete vaccination status. Conclusion:Only one-quarter of health professionals received the recommended full dose of the vaccine. Sustained hepatitis B vaccination programs for healthcare workers need to be established by collaboration of different stakeholders to optimize health professionals' safety against this contagious infection.

Project description:BackgroundDespite CDC recommendations regarding universal catch-up vaccination against human papillomavirus (HPV), only about ten percent of young adult women in the United States have been vaccinated. The purpose of this study was to better understand reasons for non-vaccination among insured 19-26 year-old women and to evaluate future vaccination intentions.MethodsWe used an administrative claims database from a large US managed care plan to identify women aged 19-26 for receipt of a mailed survey. From a sample of 1,375 women with no evidence of HPV vaccination from June 1, 2006 through April 30, 2007, 222 completed surveys were received, of which 185 were eligible for this analysis. The main outcome measures were unvaccinated women's attitudes and vaccine awareness, likelihood of future action regarding the vaccine, and reasons for inaction.ResultsAmong the 185 non-vaccinees, 25.4% were married, 83.2% were white, and 89.2% had a college or higher level education. The vaccine was described as very important by 32.4% of subjects, and 30.1% had discussed the vaccine with a doctor and received a doctor's recommendation. Half or fewer of respondents were "very" or "extremely" likely to discuss the vaccine with their doctor (50.0%), do additional research on the vaccine (42.6%), ask a doctor to get the vaccine (37.5%), or make an appointment to get the vaccine (27.8%), while 48.0% were "somewhat", "very", or "extremely" likely to do nothing to get the vaccine. Among the latter, reasons for taking no action included being married or in a monogamous relationship (54.9%), belief that the vaccine is too new (35.4%), not having enough information about the vaccine (31.7%), concerns about side effects (24.4%), and uncertainty about insurance coverage (24.4%).ConclusionsEducational interventions may be needed to enhance HPV vaccination rates among 19-26 year-old women, particularly regarding information about vaccine safety, vaccine efficacy, insurance coverage, and the value of vaccination to women in monogamous relationships.

Project description:BackgroundAttempts to maintain or increase vaccination coverage almost all focus on supply side interventions: improving availability and delivery of vaccines. The effectiveness and cost-effectiveness of efforts to increase demand is uncertain.MethodsWe performed a systematic review of studies that provided quantitative estimates of the impact of demand side interventions on uptake of routine childhood vaccination. We retrieved studies published up to Sept 2008.ResultsThe initial search retrieved 468 potentially eligible studies, including four systematic reviews and eight original studies of the impact of interventions to increase demand for vaccination. We identified only two randomised controlled trials. Interventions with an impact on vaccination uptake included knowledge translation (KT) (mass media, village resource rooms and community discussions) and non-KT initiatives (incentives, economic empowerment, household visits by extension workers). Most claimed to increase vaccine coverage by 20 to 30%. Estimates of the cost per vaccinated child varied considerably with several in the range of $10-20 per vaccinated child.ConclusionMost studies reviewed here represented a low level of evidence. Mass media campaigns may be effective, but the impact depends on access to media and may be costly if run at a local level. The persistence of positive effects has not been investigated. The economics of demand side interventions have not been adequately assessed, but available data suggest that some may be very cost-effective.

Project description:Purpose: To examine provider knowledge of HPV vaccination age guidelines in five countries. Methods: A total of 151 providers of adolescent vaccinations in Argentina, Malaysia, South Africa, South Korea, and Spain were interviewed between October 2013 and April 2014. Univariate analyses compared providers' understanding of recommended age groups for HPV vaccination to that of each country's national guidelines. Results: In three of five countries surveyed, most providers (97% South Africa, 95% Argentina, 87% Malaysia) included all nationally recommended ages in their target age group. However, a relatively large proportion of vaccinators in some countries (83% Malaysia, 55% Argentina) believed that HPV vaccination was recommended for women above age 26, far exceeding national guidelines, and beyond the maximum recommended age in the United States. National median minimum and maximum age recommendations cited by the respondents for HPV vaccination were 11 and 29 years in Argentina (national guideline: 11-14), 13 and 48 years in Malaysia (guideline 13-14), 8 and 14 years in South Africa (guideline 9-14), 10 and 20 years in South Korea (guideline 11-14), and 11 and 12 years in Spain (guideline 11-14). In all countries, a higher percentage of vaccinators included all nationally recommended ages for vaccination, as compared to providers who did not administer HPV vaccination. Conclusions: Overall, a substantial proportion of providers incorrectly reported their country's age guidelines for HPV vaccination, particularly the upper age limit. As provider recommendation is among the strongest predictors of successful vaccination uptake among adolescents, improved education and clarification of national guidelines for providers administering HPV vaccination is essential to optimize prevention of infection and associated disease.

Project description:This study evaluates knowledge, attitudes and behaviors of adolescents regarding vaccinations. A cross-sectional study was conducted among a sample of 771 adolescents, aged 11 to 18 selected from a random sample of 5 public schools, in the period between March and May 2017, in the geographical area of Naples. A self-administered questionnaire was used to seek information about: 1) socio-demographic characteristics; 2) knowledge of vaccine-preventable diseases; 3) attitudes towards vaccinations; 4) behavior regarding vaccinations. 57.2% had a fair/satisfactory knowledge of vaccine-preventable diseases. This knowledge was significantly higher in those who had at least one graduated parent, those who had received information about the vaccines from physicians and those who needed additional information about the vaccines. With regards to attitude, 41.3% of adolescents had a very favorable attitude by responding 9 or 10 towards the utility of vaccines in preventing diseases. This was significantly associated with the usefulness of information received about vaccinations and with age of respondents. Regarding vaccination decisions, 47.2% believed that adolescents should make vaccination decisions for themselves. These results highlight the need to implement educational interventions to improve adolescents' understanding of vaccinations so that they are more informed in decisions regarding their health.

Project description:BACKGROUND:Maternal influenza and pertussis vaccinations have been proven safe and effective in reducing maternal and infant morbidity and mortality. Though recommended, not all pregnant women receive these important vaccines. We aimed to evaluate the vaccine coverage of maternal immunization in pregnancy for seasonal influenza and acellular pertussis and elucidate the reasons for non-vaccination among pregnant women. The secondary objective was to describe factors that affect vaccine uptake. METHODS:A cross sectional observational study using anonymous questionnaires distributed to women in the maternity ward or pregnant women hospitalized in the high-risk ward, between Nov 2017 and June 2018, In an Israeli tertiary hospital. RESULTS:Of 321 women approached, 313 were eligible, with a total of 290 women completing the questionnaire (92.6%). We found a 75.9% (95% CI 71-81) and 34.5% (95% CI 29-40) vaccination rate for pertussis and influenza vaccines, respectively. The most prominent reason for not receiving the pertussis vaccine was being under-informed (24%). Influenza vaccine was not received mainly due to concerns about vaccine efficacy (28%). Other factors influencing vaccine uptake included education, prior childbirth and vaccine recommendations made by the provider. CONCLUSION:Although maternal vaccination of pertussis and influenza is officially recommended, vaccine uptake is suboptimal. Our study suggests a central role for medical providers in diminishing the concerns about safety and efficacy, and presents novel factors influencing compliance rates, like seasonality and number of prior births.
