Robert F. Kennedy Jr. (RFK Jr.) has publicly suggested that contracting measles might confer long-term immune benefits, including protection against certain cancers and heart disease. However, these assertions are not supported by robust scientific data. Experts emphasize that while natural infection can stimulate the immune system, the risks of measles, including severe complications and death, far outweigh any unproven potential benefits.
