Abstract Background Additional doses of COVID-19 vaccine have been proposed as solutions to waning immunity and decreased effectiveness primary against infection with new SARS-CoV-2 variants. However, the additional relies on widespread population acceptance. We aimed assess acceptance (third annual doses) among Canadian adults determine associated factors. Methods conducted a national, cross-sectional online survey from October 14 November 12, 2021. Weighted multinomial logistic regression analyses were used identify sociodemographic health-related factors third dose indecision, compared refusal. also assessed influences decision-making, preferences for future delivery. Results Of 6010 respondents, 70% reported they would accept dose, while 15.2% undecided. For doses, 64% acceptance, 17.5% Factors indecision similar those indecision. Previous receipt, no history disease, intention receive an influenza vaccine, increasing age strongly both Chronic illness was higher odds self-reported disability being Higher education attainment income accepting doses. Minority first language undecided about visible minority identity refusing dose. All respondents government recommendations important influence their decision-making identified pharmacy-based delivery drop-in appointments desirable. Co-administration vaccines viewed positively by 75.5% 3 group, 12.3% 8.4% refusal group. Conclusions To increase targeted interventions populations, disability, are required. Offering vaccination at pharmacies through facilitate uptake, offering COVID-19/influenza co-administration may little benefit

As the COVID-19 pandemic continues and transitions to an endemic stage, booster vaccines will play important role in personal public health. However, convincing people take boosters be a key obstacle. This study systematically analyzed research that examined predictors of vaccine hesitancy. A search PubMed, Medline, CINAHL, Web Science, Scopus uncovered 42 eligible studies. Globally, average vaccination hesitancy rate was 30.72%. Thirteen factors influencing emerged from literature: demographics (gender, age, education, income, occupation, employment status, ethnicity, marital status), geographical influences (country, region, residency), adverse events, perceived benefit/efficacy, susceptibility, severity, prior history infection, recommendations, health knowledge information, skepticism/distrust/conspiracy theories, type. Vaccine communication campaigns interventions for COVID should focus on confidence, complacency, convenience.

Background: Despite the availability of COVID-19 vaccines and proven benefits vaccinations outweighing potential risks, hesitancy to accept additional doses remains a persistent problem. Therefore, purpose study was investigate hesitancy, confidence, literacy, role multi-theory model (MTM) constructs in booster uptake. Methods: This cross-sectional utilized 52-item psychometric valid web-based survey conducted during month October 2021 recruit nationally representative sample U.S. adults. Univariate, bivariate, multivariate statistical tests were used analyze data. Results: Among hesitant group (n = 209, 41.7%), significantly larger proportion respondents unvaccinated with primary series (43.5% vs. 11%, p < 0.001), among 18−44 years age (51.2% 31.8%, single or never married (33.0% 24.3%, 0.04), had lower education some high school (6.2% 2.4%, 0.03), identified themselves as Republicans (31.6% 20.5%, 0.01). The mean scores vaccine 19% odds behavioral confidence than their non-hesitant counterparts (adjusted ratio 0.81, 95% CI: 0.71−0.92).
