In the survey, 50 percent of unvaccinated adults said the lack of full approval either strongly or somewhat influenced them in their decision not to get a shot.

But other reasons were even more paramount, perhaps explaining why only 29 percent of unvaccinated adults said they are likely to get a COVID-19 shot within the next month in light of Pfizer’s FDA approval.

For example, 70 percent of unvaccinated adults said they are concerned about the shot’s side effects; 61 percent said vaccination mandates are an infringement on their personal freedoms; and 60 percent said the vaccines have not been proven to be safe.
