The Infectious Disease Society of America says there have been “no deaths related to the measles, mumps and rubella vaccine in healthy individuals.” (Since the 1970s, the measles vaccine has been given in a combination shot with mumps and rubella to minimize the number of injections kids get.)

In response, Secretary of Health and Human Services Robert F. Kennedy Jr. has praised the benefits of the measles, mumps, and rubella vaccine. But he has also touted the benefits of vitamin A, cod liver oil, and good overall nutrition as ways to stem the outbreak.
