56% Of Americans Now Suspect COVID-19 ‘Vaccines’ Caused Mass-Deaths

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.

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.
