"I Would Never Push a Vaccine on You": A Qualitative Study of Social Norms and Pressure in Vaccine Behavior in the U.S.

Previous researchers have established the influence of social norms on vaccine behavior. However, little work has been performed contextualizing individuals' experience with these social factors and how they operate to persuade individuals' acceptance or refusal of a vaccine. We aimed to determine the mechanisms of familial and societal pressure or expectations that contribute to COVID-19 vaccine decision-making. We conducted four focus groups and eleven individual interviews (total n = 32) with participants from across the U.S. of different vaccination statuses. We identified three emergent themes: (1) Altruistic reasoning was particularly prevalent among initially hesitant late adopters-the desire to protect loved ones and others constituted a dominant motive, more powerful than protecting oneself. Vaccination was also reckoned as part of a joint effort to return to normal life; hence, it invoked a sense of responsibility or "obligation"; (2) expectation often became pressure; although most vaccinated participants stated that they respected others' choices, late adopters or unvaccinated participants perceived differently and felt rushed or "forced" into choosing, and many resented being "targeted" or "bullied"; (3) vaccination status became a new label, frequently dividing families, thus producing familial mandates, exclusions, or social stratifications. This caused sadness and feelings of isolation, along with the formation of a camaraderie among the excluded unvaccinated. A vaccine decision builds from the complexities of individuals' experiences and cultures. The vaccinated were not free of hesitancy nor were the unvaccinated all anti-vaxxers. Vigorous vaccine promotion successfully converted some undecided individuals but also fostered distrust of government; alarmingly, the push to receive the COVID-19 vaccine further triggered doubts about established vaccines. Communication strategies need to be developed and implemented carefully so as not to ostracize the unvaccinated community and strengthen their resistance.
