A recent video promoting independent presidential candidate Robert F. Kennedy Jr. promises to “start with some irrefutable facts.” The over 30-minute video, narrated by actor Woody Harrelson, begins with some biographical truths about the candidate, but veers into promoting various debunked or unsupported narratives about vaccines.
Small amounts of aluminum have been used for many decades to strengthen the immune response to vaccines. Exposure to high levels of aluminum has been associated with brain and bone problems, but there is no evidence that the level of exposure provided by vaccines leads to such toxicity, contrary to social media claims.
An international study of around 99 million people confirmed known serious side effects of COVID-19 vaccination. It also identified a possible relationship between the first dose of the Moderna vaccine and a small risk of a neurological condition. Social media posts about the study left out information on the vaccines’ benefits and the rarity of the side effects.
COVID-19 vaccination during pregnancy benefits both mother and baby. Side effects are generally mild, and studies don’t show negative effects on the baby. A criticized study that gave COVID-19 vaccines to pregnant rats doesn’t show that vaccines cause autism or that people shouldn’t get COVID-19 vaccines, contrary to claims.
COVID-19 vaccines are generally safe and have not killed 17 million people worldwide, contrary to claims amplified by podcaster Bret Weinstein during an interview with Tucker Carlson. Weinstein also inaccurately characterized a proposed World Health Organization pandemic accord and other changes, claiming they aim to take away “personal and national sovereignty.”
The COVID-19 vaccines have saved millions of lives, according to multiple studies. Despite this, Florida Surgeon General Dr. Joseph Ladapo issued a statement on Jan. 3 calling for a halt in the use of mRNA COVID-19 vaccines, made by Pfizer/BioNTech and Moderna.
A preprint on a Yale-based study described chronic symptoms self-reported after COVID-19 vaccination by 241 members of an online group. The paper, which has not been peer-reviewed, did not show how common these symptoms are in the general population, nor whether vaccinations caused them — limitations popular online posts did not make clear.
The mRNA COVID-19 vaccines — like many other vaccines — can contain small amounts of DNA left over from the manufacturing process. There’s no evidence this residual DNA causes “turbo cancer,” or very aggressive cancer. Nor did Moderna admit that “mRNA Jabs Cause Turbo-Cancer,” contrary to an online article that misconstrues a line from a patent application.
COVID-19 vaccination reduces the risk of death from COVID-19. Social media posts have misused survey data and adverse events reports to falsely claim that COVID-19 vaccines have killed more people than COVID-19. But serious adverse events resulting from vaccination, including deaths, are rare.
Small amounts of DNA from the manufacturing process may remain in the mRNA COVID-19 vaccines. Purification and quality control steps ensure any leftover DNA is present within regulatory limits. There isn’t reason to think that this residual DNA would alter a person’s DNA or cause cancer, contrary to claims made online.
