Multistate measles outbreak leads to dangerous vitamin A toxicity
- Amidst a measles outbreak affecting 378 people across 17 states, including Texas and New Mexico, the Council for Responsible Nutrition issued a statement cautioning against the misuse of high-dose vitamin A in attempts to prevent measles, especially in children.
- Fueled by misinformation potentially spread through social media and health influencers, there's an increased demand for cod liver oil, a source of vitamin A, despite research not establishing vitamin A's effectiveness in preventing measles infection and concerns about excessive intake leading to toxicity.
- Robert F. Kennedy Jr. Promoted a measles treatment plan including vitamin A and cod liver oil, while medical experts emphasize that vitamin A, though potentially helpful when administered by a doctor in specific cases of measles, is not a substitute for the MMR vaccine, which is 97% effective after two doses.
- Health professionals are concerned that misinformation is leading parents to administer high doses of vitamin A at home, resulting in cases of vitamin A toxicity and liver problems in unvaccinated children, with the tolerable upper intake level for preformed vitamin A being 3,000 mcg daily for adults and considerably lower limits for children.
- Experts like Dr. Peter Hotez stress that the MMR vaccine is the only proven way to prevent measles, and that relying on vitamin A instead could lead to unnecessary infections, urging increased public health information about the importance of vaccination and consulting with qualified healthcare professionals before administering supplements, especially to children.
