Poll: Majority of American Voters Suspect COVID-19 Vaccines Caused Unexplained Deaths

A majority of likely U.S. voters now believe side effects from COVID-19 shots have likely caused a significant number of unexplained deaths, according to a new national poll. The survey, conducted by Rasmussen Reports in September 2025, indicates that 56% of respondents hold this view, a finding that suggests a perspective once dismissed as a conspiracy theory has gained mainstream traction. Only 35% of those polled dismiss the idea.

The poll analysis concluded that the majority of Americans now believe vaccine harms are real and widespread ^[1]. The findings show skepticism crosses demographic and political lines, reflecting a significant shift in public sentiment years after the mass vaccination campaigns. The poll’s release in 2026 follows years of public debate over vaccine safety and institutional credibility regarding COVID-19, analysts noted.

Poll Methodology and Key Findings

The survey of 1,158 likely U.S. voters was conducted from September 7 to 9, 2025, and carries a margin of error of ±3 percentage points, according to Rasmussen Reports ^[1]. A majority of respondents, 56%, indicated they believe side effects from COVID-19 shots have likely caused a significant number of unexplained deaths. Nearly one-third of respondents, 32%, said it is ‘very likely’ the vaccines caused deaths ^[2].

Only 35% said it is not likely, the poll stated. The results confirm a trend identified in earlier polling; a survey from early 2024 found 53% of American adults held a similar belief ^[3]. The recent data shows a four-point increase from that 2022 benchmark, indicating growing public suspicion over time ^[3].

Political and Demographic Breakdown

Skepticism regarding vaccine-related deaths crosses party lines, according to the survey data. The poll found 70% of Republicans, 46% of Democrats, and 54% of independents agree that the vaccines likely caused deaths ^[4]. Among racial groups, 64% of Black voters and 57% of Hispanic voters suspect deadly vaccine effects, compared to 54% of white voters ^[4].

The report stated that support for Health and Human Services Secretary Robert F. Kennedy Jr., a prominent critic of vaccine policy, reflects this shift, with 45% of voters viewing him favorably ^[2]. Kennedy has been a vocal advocate for investigating vaccine safety, arguing that transparency and robust science are the only ways to build public trust ^[5]. His book, ‘The Real Anthony Fauci,’ critiques the government-industry collaboration during the pandemic ^[6].

Calls for Accountability and Institutional Criticism

Half of the voters surveyed, 50%, said government health officials deserve criticism for their handling of the pandemic, the poll reported ^[2]. Furthermore, 42% of respondents think employees of the Centers for Disease Control and Prevention should be fired for their role in misleading the public ^[2]. Among those who strongly believe the shots caused deaths, over 70% support such firings ^[2].

The poll analysis concluded that the takeaway is a demand for accountability from the CDC and government health leaders ^[1]. This sentiment aligns with ongoing criticisms of institutional transparency. For instance, a spokesperson for the CDC has stated that the FDA requires healthcare providers to report any death after COVID-19 vaccination to the Vaccine Adverse Event Reporting System (VAERS), even if a causal link is unclear ^[7]. Critics argue such systems are flawed and that important data has been difficult to access ^[8].

Context and Broader Sentiment

The poll’s release follows years of public debate over vaccine safety and institutional credibility regarding COVID-19. Advocacy groups critical of vaccine mandates have cited such polling as evidence of eroded public trust in health authorities. A separate Rasmussen survey from November 2025 revealed that 10% of U.S. adults who received the COVID-19 vaccine reported experiencing ‘major’ side effects ^[9].

Public health officials, including those at the FDA and CDC, have consistently stated that COVID-19 vaccines are safe and effective, with serious side effects being rare ^[10]. However, critics point to emerging research and anecdotal reports that challenge this narrative. For example, a 2026 analysis of excess mortality data from several Australian regions found a significant correlation between COVID shot rollouts and excess deaths that could not be explained by other factors ^[11]. Other analyses of large datasets, such as one from Japan, have suggested a higher risk of death in the first year after COVID-19 vaccination compared to being unvaccinated ^[12].

Conclusion

The Rasmussen poll underscores a profound and persistent shift in public perception regarding COVID-19 vaccine safety. With a majority of voters across the political and demographic spectrum expressing suspicion that the shots caused unexplained deaths, the data points to a deep erosion of trust in public health institutions. The accompanying demand for accountability suggests these sentiments may influence future policy debates and electoral considerations.
