Factors associated with receiving an initial COVID-19 vaccine among Alaskan residents: results from an online cross-sectional survey

We conducted an online survey of Alaskan adults between May and June, 2022 to identify factors associated with vaccine hesitancy. Of the 948 respondents, approximately 80% reported having received a COVID-19 vaccine. The factors significantly associated with ever receiving COVID-19 vaccine include perceived risk of harm if not vaccinated (PRH), the vaccination status of the respondent’s social network (SNW), gender, and education. For each point increase in PRH score, there was more than three times the odds of having ever been vaccinated (OR = 3.42, p < 0.001); and for every point increase in SNW score, there was more than two times the odds of having ever been vaccinated (OR = 2.15, p < 0.001). Males had more than four times the odds of having ever been vaccinated compared to females (OR = 4.55, p < 0.001). Those with a college degree (OR = 2.80, p < 0.05) had greater odds of ever being vaccinated compared to their counterparts. Findings from this sample suggest that, among Alaskans, ever receiving a COVID-19 vaccine is associated with having a majority of their close social networks who have received COVID-19 vaccine and perceiving that not obtaining a COVID-19 vaccine can pose greater risk of harm to themselves than not getting vaccinated. Practical implications of these findings are provided.
