Prevalence and factors associated with hepatitis b vaccination uptake and completion among communities targeted for mass vaccination in gulu: a cross-sectional study. BMC Public Health 2024; 24:866. [PMID: 38509496 PMCID: PMC10956285 DOI: 10.1186/s12889-024-18330-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 03/11/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND Hepatitis B virus (HBV) is associated with several acute and long-term complications and vaccination is the cornerstone of prevention. A recent outbreak in Gulu, Uganda, one of the districts covered by a mass vaccination campaign, suggests low uptake of HBV vaccination. This study aims to determine the uptake and completion of HBV vaccination and associated factors among residents of Gulu, Uganda. METHODS A mixed methods cross-sectional study was conducted in Gulu, Northern Uganda, among 434 adult residents. A pretested questionnaire was used to collect data on socio-demographics, perceptions, and knowledge of HBV vaccination. Modified Poisson regression analysis was used in STATA 14 software to obtain prevalence ratios for the association between the independent and dependent variables. For qualitative data, 9 key informant interviews were conducted and thematic analysis was done using Quirkos software. RESULTS Out of the 434 respondents, 41.9% had received at least one dose of the hepatitis B vaccine, 32.5% had received at least 2 doses, and only 20% had completed all 3 doses, with an overall completion rate of 47.8% for participants who had been initiated on the vaccine. Gender, residence, risk perception of Hepatitis B infection, perceived safety of the vaccine, and awareness of mass vaccination were associated with uptake of Hepatitis B vaccination. Residence, knowledge, and perception of being at risk of acquiring Hepatitis B were associated with completion. Qualitative results revealed that the levels of uptake and completion could have been affected by access to vaccination sites; inadequate knowledge about the disease; myths about the vaccine and inadequate community engagement. CONCLUSION Low Hepatitis B vaccine uptake and completion rates were observed in Gulu. To enhance vaccination coverage, future initiatives should prioritize awareness, education, and dispelling of vaccination myths. Additionally, increased government investment in training health workers can serve as a valuable strategy to improve information dissemination and awareness among the population.

Abstract
To reach the goals of the Global Hepatitis Elimination 2030 program, Indonesia is now preparing a new regulation for hepatitis B vaccinations for adult population. This study aimed to determine the factors influencing vaccine uptake for hepatitis B in the adult population, and identify barriers to, and facilitators of, hepatitis B vaccination programmes. An explanatory sequential mixed methods design was implemented in this study. We conducted a survey involving 893 participants in the general population followed by 14 in-depth interviews with health providers. The survey found that only 15% (95% confidence interval 13-18%) of participants received at least one dose of the hepatitis B vaccine. Factors associated with vaccine uptake were, living in Yogyakarta compared to living in Aceh, having secondary and higher education compared to primary education, working as a health worker compared to working in other sectors, and having health insurance that covered hepatitis B vaccination compared to not having such health insurance. Our qualitative study also identified several barriers to the adult hepatitis B vaccination programme in Indonesia such as the high cost of vaccination, lack of vaccine availability in certain areas, limited human resources to implement the hepatitis B vaccination programme, and the ineffective dissemination of hepatitis B vaccination. This study highlights that accessibility and affordability of vaccinations are important determinants of vaccination uptake that should be taken into account when planning vaccination campaigns.

Abstract
Hepatitis B virus (HBV) infection represents a significant global health threat, accounting for 300 million chronic infections and up to 1 million deaths each year. HBV disproportionately affects people who are under-served by health systems due to social exclusion, and can further amplify inequities through its impact on physical and mental health, relationship with stigma and discrimination, and economic costs. The 'inclusion health' agenda focuses on excluded and vulnerable populations, who often experience barriers to accessing healthcare, and are under-represented by research, resources, interventions, advocacy, and policy. In this article, we assimilate evidence to establish HBV on the inclusion health agenda, and consider how this view can inform provision of better approaches to diagnosis, treatment, and prevention. We suggest approaches to redress the unmet need for HBV interventions among excluded populations as an imperative to progress the global goal for the elimination of viral hepatitis as a public health threat.

PLoS One 2023; 18:e0281256. [PMID: 36730277 PMCID: PMC9894478 DOI: 10.1371/journal.pone.0281256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Accepted: 01/18/2023] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Hepatitis B is becoming a growing public health problem in Kenya. To combat the threat, HBV vaccination should be recommended, particularly for individuals who are not covered by the national immunization program. Vaccination provides sero-protection rates approaching 95% among healthy adults after completing the three-dose vaccination course, but decreases to 87% among those who receive only two doses, emphasizing the importance of completing the three-dose vaccination course. However, data on adult adherence to HBV multi-dose vaccines in Sub-Saharan Africa are limited, despite the fact that this information is critical for prevention. As a result, more research on HBV vaccine dose completion is required. The purpose of this study is to estimate the prevalence of hepatitis B virus infection among out-patient clinic attendees in Nairobi, Kenya, as well as to identify beneficiaries of free vaccination and barriers to completing the recommended vaccine doses. METHODS Between July 30th and September 30th, 2015, 2644 outpatient clinic attendees aged ≥ 4 were recruited from three hospitals in Nairobi County, Kenya: Mama Lucy, Riruta, and Loco. Self-administered questionnaires were used to collect socio-demographic information, and blood samples were tested for hepatitis B surface antigen (HBsAg) using the KEMRI HEPCELL Rapid® (Hepatitis B Detection kit) test kit. Individuals who tested negative for HBsAg were given a free course of three doses of HBV vaccine. The vaccination register provided information on the number of doses administered. RESULTS The average age of the study population was 31.4 years (range: 4-66), with females accounting for 59.2%. 1.82% (48/2644) of the participants tested positive for HBsAg. Among the 2596 individuals eligible for vaccination, 66% (1720/2596) received at least one dose, and 51.8% (1345/2596) received all three doses. Vaccination acceptance increased with age, with older patients more likely to return for subsequent dose (OR>1 for second and third dose). Unavailability and failure to contact client were cited as significant (p<0.0001) barrier to vaccination completion by 53.7% (666/1226, 95% CI 0.5-0.6) and 37% (454/1226, 95% CI 0.3-0.4) of respondents respectively. CONCLUSION The prevalence of HBV infection among outpatient clinic attendees highlights the importance of expanding HBV immunization programs in Kenya. However, given the low vaccination completion rate, there is a need for public awareness of the vaccine's importance in preventing HBV and HBV-related complications.

Abstract
Vaccination has been confirmed to be the safest and, sometimes, the only tool of defense against threats from infectious diseases. The successful history of vaccination is evident in the control of serious viral infections, such as smallpox and polio. Viruses that infect human livers are known as hepatitis viruses and are classified into five major types from A to E, alphabetically. Although infection with hepatitis A virus (HAV) is known to be self-resolving after rest and symptomatic treatment, there were 7134 deaths from HAV worldwide in 2016. In 2019, hepatitis B virus (HBV) and hepatitis C virus (HCV) resulted in an estimated 820,000 and 290,000 deaths, respectively. Hepatitis delta virus (HDV) is a satellite virus that depends on HBV for producing its infectious particles in order to spread. The combination of HDV and HBV infection is considered the most severe form of chronic viral hepatitis. Hepatitis E virus (HEV) is another orally transmitted virus, common in low- and middle-income countries. In 2015, it caused 44,000 deaths worldwide. Safe and effective vaccines are already available to prevent hepatitis A and B. Here, we review the recent advances in protective vaccines against the five major hepatitis viruses.

Abstract
Vaccination has a significant impact on morbidity and mortality. High vaccination coverage rates are required to achieve herd protection against vaccine-preventable diseases. However, limited vaccine access and hesitancy among specific communities represent significant obstacles to this goal. This review provides an overview of critical factors associated with vaccination among disadvantaged groups in World Health Organisation European countries. Initial searches yielded 18,109 publications from four databases, and 104 studies from 19 out of 53 countries reporting 22 vaccine-preventable diseases were included. Nine groups representing the populations of interest were identified, and most of the studies focused on asylum seekers, refugees, migrants and deprived communities. Recall of previous vaccinations received was poor, and serology was conducted in some cases to confirm protection for those who received prior vaccinations. Vaccination coverage was lower among study populations compared to the general population or national average. Factors that influenced uptake, which presented differently at different population levels, included health service accessibility, language and vaccine literacy, including risk perception, disease severity and vaccination benefits. Strategies that could be implemented in vaccination policy and programs were also identified. Overall, interventions specific to target communities are vital to improving uptake. More innovative strategies need to be deployed to improve vaccination coverage among disadvantaged groups.

Predictors of Hepatitis B screening and vaccination status of young psychoactive substance users in informal settlements in Kampala, Uganda. PLoS One 2022; 17:e0267953. [PMID: 35588113 PMCID: PMC9119510 DOI: 10.1371/journal.pone.0267953] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 04/19/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Young psychoactive substance users exhibit high-risk behaviours such as unprotected sexual intercourse, and sharing needles and syringes, which increases their risk of Hepatitis B infection. However, there is limited evidence of screening, and vaccination status of this subgroup. The aim of this study was to establish the predictors of screening and completion of the hepatitis B vaccination schedule. METHODS A cross-sectional study using respondent driven sampling was used to enrol respondents from twelve out of fifty-seven informal settlements in Kampala city. Data were collected using an electronic structured questionnaire uploaded on the KoboCollect mobile application, and analysed using Stata version 14. A "modified" Poisson regression analysis was done to determine the predictors of screening while logistic regression was used to determine the predictors of completion of the Hepatitis B vaccination schedule. RESULTS About 13.3% (102/768) and 2.7% (21/768) of the respondents had ever screened for Hepatitis B, and completed the Hepatitis B vaccination schedule respectively. Being female (aPR 1.61, 95% CI: 1.11-2.33), earning a monthly income >USD 136 (aPR 1.78, 95% CI: 1.11-2.86); completion of the Hepatitis B vaccination schedule (aPR 1.85, 95% CI: 1.26-2.70); lack of awareness about the recommended Hepatitis B vaccine dose (aPR 0.43, 95% CI: 0.27-0.68); and the belief that the Hepatitis B vaccine is effective in preventing Hepatitis B infection (aPRR 3.67, 95% CI: 2.34-5.73) were associated with "ever screening" for Hepatitis B. Knowledge of the recommended Hepatitis B vaccine dose (aOR 0.06, 95% CI: 0.01-0.35); "ever screening" for hepatitis B (aOR 9.68, 95% CI: 2.17-43.16) and the belief that the hepatitis B vaccine is effective in preventing Hepatitis B infection (aOR 11.8, 95% CI: 1.13-110.14) were associated with completion of the hepatitis B vaccination schedule. CONCLUSIONS Our findings indicate a low prevalence of Hepatitis B screening and completion of the Hepatitis B vaccination schedule among young psychoactive substance users in informal settings. It is evident that lack of awareness about Hepatitis B is associated with the low screening and vaccination rates. We recommend creation of awareness of Hepatitis B among young people in urban informal settlements.

Partida D, Powell J, Gonzalez D, Khalili M. Gaps in hepatitis A and hepatitis B vaccination among hepatitis C antibody positive individuals experiencing homelessness. Open Forum Infect Dis 2022; 9:ofac175. [PMID: 35531381 PMCID: PMC9070334 DOI: 10.1093/ofid/ofac175] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Accepted: 04/04/2022] [Indexed: 11/28/2022] Open
Abstract
Vaccination for both hepatitis A (HAV) and hepatitis B (HBV) is recommended in hepatitis C infection (HCV). Among HCV antibody–positive persons experiencing homelessness, we identified high rates of HAV (34%) and HBV vaccine (35%) eligibility, highlighting critical gaps in HCV preventative services. Following education, 54% and 72% underwent HAV and HBV vaccination, respectively.

Abstract
BACKGROUND In 2016, approximately 42,000 women were incarcerated in Brazil. The objectives of this study were to measure the lifetime prevalence of syphilis and sociodemographic and behavior correlates of antibody positivity among female prisoners in Brazil. METHODS We conducted a cross-sectional survey of 1327 incarcerated women in 2014 to 2015 sampled through a multistage cluster design to represent the penitentiary system throughout Brazil. A rapid treponemal antibody test approved by the Ministry of Health (Rapid Test DPP Sífilis Bio-Manguinhos) was used to detect lifetime history of infection. Analyses were adjusted using weights based on the inverse of the product of the probabilities of the sampling units at each stage of the design. Variables significantly associated with syphilis infection at P < 0.05 in multivariate analyses were retained in the final model. RESULTS Prevalence of syphilis antibody among female prisoners in Brazil was 11.6% (95% confidence interval [CI], 9.8%-13.8%). Higher syphilis prevalence was associated with black/Afro-Brazilian or mixed race/ethnicity (adjusted odds ratio [AOR], 1.78; 95% CI, 1.10-2.87), homelessness (AOR, 4.58; 95% CI, 2.78-7.56), abortion (AOR, 1.56; 95% CI, 1.02-2.38), and sexual violence (AOR, 1.59; 95% CI, 1.01-2.49). Syphilis prevalence was lower among women who had received condoms in school (AOR, 0.28; 95% CI, 0.08-1.00) as a marker for reproductive health education. CONCLUSIONS Women within the vast Brazilian prison system demonstrate a high lifetime cumulative incidence of syphilis. Our data advocate for increased screening and treatment of syphilis of incarcerated women and help identify women at higher risk within the prison system and within their communities of origin.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17218045. [PMID: 33142883 PMCID: PMC7663669 DOI: 10.3390/ijerph17218045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 10/27/2020] [Accepted: 10/28/2020] [Indexed: 12/02/2022]
Abstract
The correct immunization of the inmate population minimizes the risk of transmission of vaccine-preventable diseases in prisons. The objective of this study was to evaluate the vaccine coverage of long-term prisoners in the Spanish penitentiary system through a retrospective longitudinal study. One-thousand and five prisoners were selected, who were imprisoned from 2008 and 2018 in three Spanish prisons. Their degree of immunization was evaluated as related to hepatitis A (HAV), hepatitis B (HBV), tetanus, diphtheria, pneumococcus and seasonal flu. The state of vaccination of the prisoners with a serological diagnosis of HBV, hepatitis C (HCV) and human immunodeficiency virus (HIV) was also evaluated. The vaccination coverage obtained for hepatitis B was 52.3%, and for tetanus–diphtheria, it was 71.9%. However, for hepatitis A and pneumococcus infection, it was insignificant (<2% of the prisoners). Vaccination against seasonal flu was lower than 16%. The HCV and HIV-positive inmates were not correctly vaccinated either. The insufficient level of immunization obtained reflects the lack of interest and marginalization of this population by the penitentiary system and the health authorities. The lack of reliable records is combined with the lack of planned strategies that promote stable and well-defined programs of active vaccination.

Vaccination Coverage among Prisoners: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17207589. [PMID: 33086513 PMCID: PMC7589151 DOI: 10.3390/ijerph17207589] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Revised: 10/03/2020] [Accepted: 10/14/2020] [Indexed: 12/26/2022]
Abstract
Prison inmates are highly susceptible for several infectious diseases, including vaccine-preventable diseases. We conducted a systematic international literature review on vaccination coverage against hepatitis B virus (HBV), hepatitis A virus (HAV), combined HAV/HBV, tetanus-diphtheria, influenza, pneumococcal, and combined measles, mumps, and rubella (MMR) in prison inmates, according to the PRISMA guidelines. The electronic databases were used Web of Science, MEDLINE, Scopus, and Cinhal. No language or time limit were applied to the search. We defined vaccination coverage as the proportion of vaccinated prisoners. There were no limitations in the search strategy regarding time period or language. Of 1079 identified studies, 28 studies were included in the review. In total, 21 reported on HBV vaccine coverage (range between 16–82%); three on HAV (range between 91–96%); two studies on combined HAV/HBV (77% in the second dose and 58% in the third); three studies on influenza vaccine (range between 36–46%), one of pneumococcal vaccine coverage (12%), and one on MMR coverage (74%). We found that data on vaccination coverage in prison inmates are scarce, heterogeneous, and do not include all relevant vaccines for this group. Current published literature indicate that prison inmates are under-immunized, particularly against HBV, influenza, MMR, and pneumococci. Strengthen immunization programs specifically for this population at risk and improvement of data record systems may contribute to better health care in prisoners.

Gaps in Hepatitis B Vaccination Completion and Sero-Protection for People Who Inject Drugs in Hpakant, Myanmar, 2015-2018. Trop Med Infect Dis 2020; 5:tropicalmed5020077. [PMID: 32408591 PMCID: PMC7344405 DOI: 10.3390/tropicalmed5020077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Revised: 02/17/2020] [Accepted: 03/13/2020] [Indexed: 11/22/2022] Open
Abstract
Hepatitis B vaccination (HBV) is recommended for high-risk groups, such as people who inject drugs (PWIDs). As part of a harm reduction program by a non-governmental organization, hepatitis B screening, vaccination and antibody (HBAb) testing after completion of the vaccination schedule were offered to PWIDS in Myanmar. We determined the proportions of HBV non-completion and sero-unprotection among PWIDs enrolled in the program and their association with socio-demographic and clinical characteristics. We conducted a descriptive study based on routine program data in five selected clinics in Hpakant Township, Myanmar. PWIDs who were Hepatitis B antigen negative at screening during January 2015–December 2018 were included. Among 5386 participants eligible for HBV, 9% refused vaccination. Among those who accepted vaccination (n = 3177 individuals), 65% completed vaccination. Of those tested for HBsAb (n = 2202), 30% were sero-unprotected. Young-adults (aged 18–44 years) and migrant workers had a higher risk of incomplete vaccination. However, participants who used methadone had a lower risk of incomplete vaccination. Migrant workers had higher risk of not returning for HBsAb testing and HIV-positive participants had a higher risk of being HBV sero-unprotected. Efforts to increase HBV vaccination in PWIDs for young adults and clients during methadone and anti-retroviral services should be prioritized.

Miler JA, Carver H, Foster R, Parkes T. Provision of peer support at the intersection of homelessness and problem substance use services: a systematic 'state of the art' review. BMC Public Health 2020; 20:641. [PMID: 32381086 PMCID: PMC7203893 DOI: 10.1186/s12889-020-8407-4] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Accepted: 02/25/2020] [Indexed: 01/13/2023] Open
Abstract
Background Peer support refers to a process whereby individuals with lived experience of a particular phenomenon provide support to others by explicitly drawing on their personal experience. It has been adopted in a variety of service contexts including homelessness, substance use, mental and physical health. Those who experience homelessness have some of the most complex intersecting health and social challenges. This ‘state of the art’ review provides a systematic search and synthesis of literature examining use of peer support models within services for people impacted by homelessness and problem substance use. Methods A systematic search using six databases (CINAHL, SocINDEX, PsycINFO, MEDLINE, Scopus and Web of Knowledge) was conducted in August 2019 and identified 2248 papers published in English after the year 2000. After de-duplication and scanning titles/abstracts, 61 papers were deemed relevant. Three more papers (including one grey literature report) were identified via references, but two papers were later excluded due to relevance. The final 62 papers included studies conducted in five countries. A thematic analysis approach was used to compare and contrast the study findings and provide a synthesis of the main learning points. Results In recent years there has been a substantial increase in research examining the utility of peer support yet there is significant variation across this field. Alongside profiling the range of settings, aims, populations, and main outcomes of these studies, this paper also provides an overview of overarching themes: the overall effectiveness and impact of peer-staffed or peer-led interventions; and challenges commonly faced in these roles. Five themes relating to the challenges faced by peers were identified: vulnerability, authenticity, boundaries, stigma, and lack of recognition. Conclusions While our findings provide support for current efforts to involve individuals with lived experience in providing peer support to those experiencing concurrent problem substance use and homelessness, they also urge caution because of common pitfalls that can leave those providing the support vulnerable. We conclude that peers should be respected, valued, supported, and compensated for their work which is often profoundly challenging. Suggested guidelines for the implementation of peer involvement in research studies and service delivery are presented.
