Under ardent anti-vaccine activist Robert F. Kennedy Jr, federal health officials are working to link COVID-19 mRNA vaccines to the deaths of 25 children, and may further restrict access to the shots, possibly recommending them for people aged 75 and up, instead of 65 and up, according to The Washington Post.

Four unnamed sources close to the situation told the Post that Trump administration health officials appear to be using information from the Vaccine Adverse Event Reporting System (VAERS) to make the claim that COVID-19 vaccines have killed children.

VAERS is a system in which anyone can report anything they think is an adverse event related to a vaccination. The reports are completely unverified upon submission, and the Centers for Disease Control and Prevention staff follow up on serious reports to try to substantiate claims and assess if they were actually caused by a vaccine. They rarely are.
