Major companies’ vaccine mandates— many implemented before President Biden required them for companies with over 100 employees—are chipping away at vaccine resistance. 

According to the CDC, about 77% of American adults have received at least one dose of the vaccine. 

Tyson Foods announced it has vaccinated 91% of its employees two months after the company announced its vaccine mandate. Nearly 100% of United Airlines’ 67,000 U.S. employees have been vaccinated. Only two major airlines have yet to announce vaccine mandates, stymied by union opposition. And health care sector vaccine mandates have increased vaccination rates in states like New York, California and even Texas.

But a recent national poll conducted by the public-health focused de Beaumont Foundation and Morning Consult found two thirds of unvaccinated adults feel “vaccine requirements are a greater threat to my health and safety than being exposed to COVID-19.” And 77% said they do not trust the government’s vaccine guidance.

At the same time, 39% cited FDA approval as a factor that would impact their decision to get vaccinated, and a quarter cited employer requirements. Other popular factors included fewer testing requirements (24%), entertainment venue requirements (23%) and their children begging them to (22%).
