Majority of Americans Now Suspect COVID-19 "Vaccines" Caused Mass Deaths
Rasmussen survey finds 56% of U.S. voters believe COVID shots caused significant deaths — and 42% say CDC employees should be fired for their pandemic response.
Public opinion is shifting—and they want action.
A new Rasmussen survey of 1,158 likely U.S. voters—conducted September 7–9, 2025, with a ±3% margin of error—reveals that 56% believe side effects from the COVID-19 shots have likely caused a significant number of unexplained deaths. Nearly one-third (32%) say it’s very likely. Only 35% still dismiss the idea.
This shows that what was once called a “conspiracy theory” has become the mainstream view. The majority of Americans now believe vaccine harms are real and widespread.
Support for HHS Secretary Robert F. Kennedy Jr. reflects this shift. Half of voters (50%) say government health officials deserve criticism for their handling of the pandemic, while 42% even think CDC employees should be fired for their role in misleading the public. Among those who strongly believe the shots caused deaths, over 70% want CDC firings.
Partisan divides remain—70% of Republicans, 46% of Democrats, and 54% of independents think the vaccines likely caused deaths—but the skepticism crosses party lines and racial groups. In fact, black (64%) and Hispanic (57%) voters are even more likely than white voters (54%) to suspect deadly vaccine effects.
According to the survey, RFK Jr. is viewed favorably by 45% of voters, with strong support among Republicans and independents, even as Democrats turn sharply against him.
The takeaway: A credible, nationally representative poll now confirms most Americans believe COVID-19 shots have killed many people, and they want accountability from the CDC and government health leaders.

Firing is good. Criminal charges is best.
Well, it’s about damn time. Way too late for my dear departed brother, as well as millions more across the globe. Murderers.
