Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.
Claimant: Robert F. Kennedy Jr.
Claim: Adverse events listed in vaccine package inserts show vaccines cause chronic illnesses such as diabetes, asthma, autoimmune diseases and sudden infant death syndrome.
Rating: BLATANT LIE
Explanation: Vaccine package inserts can list health problems reported after vaccination, including events reported voluntarily after a vaccine reaches the market. Such listings do not establish that the vaccine caused those conditions, and their presence in an insert is not evidence that vaccines cause the chronic illnesses Kennedy cited.
