Studies have shown that the protection afforded by COVID-19 vaccines against hospitalization and death decreases slowly over time due to emergence of new variants waning immunity. Accordingly, booster doses remain critical minimizing health impacts pandemic. This study examined prevalence rate, sociodemographic determinants, motivators getting a vaccine within Canadian population. We recruited representative sample 3001 Canadians aged 18+ years as part iCARE using an online polling form between 20 January 2 February 2022. Participants self-reported their status were dichotomized into two groups: those who did vs. not receive at least one dose. A total 67% participants received Chi-square analyses revealed older age (p < 0.001) having chronic disease diagnosis associated with being more likely get booster. Boosted individuals reported tied efficacy altruism, whereas non-boosted safety. Results suggest messaging will require careful tailoring address identified behavioral among emphasize safety additional doses.

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.
