“…However, the fact that two-thirds of PWIDs clients completed hepatitis B vaccination demonstrated the performance of our harm reduction program for PWIDs. It compares favorably with hepatitis B vaccination programs elsewhere: 52% completion rates in UK [12], 47%, 31% and 27% in different US settings [13] and 59.2% of PWIDs who had received a first dose in Sweden [14].…”

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.

“…This is lower than the vaccination rates among adults in the United States, where 91.6% have received at least one dose of a COVID-19 vaccine 10 . Another study found that when colocating hepatitis B vaccines with SSPs in Sweden, PWID had high initiation (75%) and completion (59%) of the series 11 . These studies speak to PWID as an underserved population and highlight SSPs as an ideal location for delivery of primary prevention services.…”

High Primary COVID-19 Vaccine Series Completion by People Who Inject Drugs When Colocating Services at a Syringe Services Van

The aim of the study is to describe the impact of colocating COVID-19 vaccinations with local syringe service programs on vaccine completion among people who inject drugs. Methods: Data were derived from 6 community-based clinics. People who inject drugs who received at least one COVID-19 vaccine from a colocated clinic partnering with a local syringe service program were included in the study. Vaccine completion was abstracted from electronic medical records; additional vaccinations were abstracted using health information exchanges embedded within the electronic medical records. Results: Overall, 142 individuals with a mean age of 51 years, predominantly male (72%) and Black, non-Hispanic (79%) received COVID-19 vaccines. More than half elected to receive a 2-dose mRNA vaccine (51.4%). Eighty-five percent completed a primary series, and 71% of those who received a mRNA vaccine completed the 2-dose series. Booster uptake was 34% in those completing a primary series. Conclusions: Colocated clinics are an effective means of reaching vulnerable populations. As the COVID-19 pandemic continues and need for annual booster vaccines arises, it is important to bolster public support and funding to continue low-barrier preventive clinics colocated with harm reduction services for this population.

“…Vaccine‐resistant participants were most likely to report predominantly injecting methamphetamine in the month preceding interview. People who inject methamphetamine tend to engage less with primary health services than those who inject opioids [45], which can have negative flow‐on effects (e.g., lower hepatitis B vaccine acceptance [46], lower hepatitis C virus testing and treatment engagement [47]). Indeed, vaccine‐resistant participants in this study were also less likely than hesitant participants to have attended a GP for drug and/or alcohol‐related reasons in the past 6 months.…”

Introduction:We aimed to describe COVID-19 vaccination attitudes and identify potential facilitators for vaccine uptake among people who inject drugs.Methods: People who inject drugs were recruited from all eight Australian capital cities (N = 884; 65% male, mean age 44 years) and interviewed face-to-face or via telephone in June-July 2021. COVID-19 and broader vaccination attitudes were used to model latent classes. Correlates of class membership were assessed through multinomial logistic regression. Probability of endorsing potential vaccination facilitators were reported by class. Results: Three classes of participants were identified: 'vaccine acceptant' (39%), 'vaccine hesitant' (34%) and 'vaccine resistant' (27%). Those in the hesitant and resistant groups were younger, more likely to be unstably housed and less likely to have received the current season influenza vaccine than the acceptant group.In addition, hesitant participants were less likely to report a chronic medical condition than acceptant participants. Compared to vaccine acceptant and hesitant participants, vaccine-resistant participants were more likely to predominantly inject methamphetamine and to inject drugs more frequently in the past month.Both vaccine-hesitant and resistant participants endorsed financial incentives for vaccination and hesitant participants also endorsed facilitators related to vaccine trust.Discussion and Conclusion: People who inject drugs who are unstably housed or predominantly inject methamphetamine are subgroups that require targeted interventions to increase COVID-19 vaccination uptake. Vaccine-hesitant people may benefit from interventions that build trust in vaccine safety and utility. Financial incentives may improve vaccine uptake among both hesitant and resistant people.
