More than two years after Operation Warp Speed began, Children’s Health Defense (CHD) commissioned John Zogby Strategies to conduct two surveys about attitudes and the overall health of American adults.

The first survey of 1,038 adults found that 67% of respondents received one or more COVID-19 vaccines, while 33% are unvaccinated. Furthermore, among those vaccinated, 6% received one dose, 28% received two doses, 21% received three doses, and 12% took four or more.

Of those receiving a COVID-19 vaccine, 15% say they’ve been diagnosed by a medical practitioner with a new condition within a matter of weeks to several months after taking the vaccine.

A follow-up question provided a list of medical conditions and asked diagnosed respondents to “select all that apply.”
