As measles spreads in Texas, New Mexico, and other states, a Texas child died from measles for the first time in the United States since 2015. In a March 2 Fox News editorial, Health and Human Services Secretary Robert F. Kennedy Jr. hinted at the importance of vaccination and stated that good nutrition, including vitamin A, is a “best defense against most chronic and infectious illnesses.”
However, doctors and public health professionals say that vitamin A is not a replacement for the measles, mumps, and rubella (MMR) vaccine. Vitamin A is sometimes used to treat measles in the hospital—particularly in developing countries where people with poor nutrition tend to be vitamin A deficient. Experts also say that taking vitamin A when your body does not need it can be dangerous.
