A CDC advisory panel vote to recommend against use of seasonal influenza vaccines containing small amounts of thimerosal followed a presentation that misled on the risks of the rarely used preservative. There isn’t evidence that thimerosal in vaccines is harmful, and studies assessing a variety of health problems, including neurological conditions, have supported its safety.
A document the Department of Health and Human Services distributed to members of Congress to justify recent changes to COVID-19 vaccine recommendations misrepresented scientific research to make unfounded claims about vaccine safety for pregnant people and children.
The Department of Health and Human Services has defended cuts to vaccine research with statements that mislead on the safety of mRNA technology, despite an extensive history of testing.
In the past two weeks, U.S. public health authorities have skirted normal procedures and announced two major policy changes that will likely reduce access to COVID-19 vaccines and restrict use to higher-risk populations. Here, we explain what we know — and don’t — about these new COVID-19 vaccine policies.
Since regaining power in January, the Trump administration has repeatedly claimed with false certainty that the COVID-19 pandemic originated in a lab. But there isn’t clear evidence that the virus came from a lab. A new government website promoting the claim also gets some basic facts wrong.
In recent interviews, Health and Human Services Secretary Robert F. Kennedy Jr. has minimized the risk COVID-19 poses to kids and exaggerated the risk of the vaccine, incorrectly claiming that the shot poses a “profound risk” to children. While serious side effects can occur, they are rare, and have not been shown to outweigh the benefits of the vaccine in protecting against COVID-19.
In his second day of confirmation hearings, Robert F. Kennedy Jr., President Donald Trump’s pick to lead the Department of Health and Human Services, refused to say that vaccines do not cause autism — despite a large body of evidence showing there is no link. He also pointed to a flawed paper to suggest that there is credible evidence to claim vaccines cause the disorder.
An abundance of evidence indicates the mRNA COVID-19 vaccines are remarkably safe and work well to protect against severe disease. But last month, the state of Florida issued updated vaccine guidance advising “against the use” of the shots entirely — even for people who are older and at higher risk of severe disease. Experts say the advice is ill-informed and “illogical.”
Responding to rising mpox cases in Africa, the World Health Organization declared a public health emergency of international concern on Aug. 14. Social media posts subsequently repeated a plethora of false or baseless claims, including that COVID-19 vaccines cause the viral disease or that the current outbreak is part of a global conspiracy.
COVID-19 vaccination is generally very safe, and except for extremely rare cases, there is no evidence that it contributes to death. Social media posts about a now-published, but faulty review of autopsy reports, however, are repeating an unfounded claim from last summer that “74% of sudden deaths are shown to be due to the COVID-19 vaccine.”
