In the midst of a growing measles outbreak in Texas that has killed one child, Health and Human Services Secretary Robert F. Kennedy Jr. has misleadingly focused on vitamin A, including from cod liver oil, and two non-standard medications as treatments for measles.

Vitamin A is recommended around the world for measles because there is evidence it can help if someone is deficient, but the benefit to patients in the U.S. is unclear. Cod liver oil, which contains vitamin A, isn’t advised at all for measles — and would need to be consumed in a potentially dangerous amount to get the recommended dosage of the vitamin used during an infection.

The other medications Kennedy has discussed, a steroid and an antibiotic, aren’t specific treatments for measles, experts told us. Neither vitamin A nor these medications replace vaccination, which is safe and effective in preventing the highly contagious disease.

Kennedy made his remarks in an interview with Fox News medical correspondent Dr. Marc Siegel. Snippets of the interview were featured in four Fox News or Fox Business segments airing on March 4.
