Measles cases are surging in the US, with over 222 cases reported in just a few months of 2025. This is a stark reminder of how quickly this highly contagious disease can spread. Two lives have been lost in Texas and New Mexico, including a school-aged child who was not vaccinated.

The debate around measles prevention has heated up. While the measles, mumps, and rubella (MMR) vaccine is widely recognized as the best defense against measles, some are suggesting alternative methods. Vitamin A supplementation, cod liver oil, and overall good nutrition have been mentioned as potential ways to combat the outbreak.

Vitamin A is often recommended by the World Health Organization for children with measles, especially in low-income countries where malnutrition is common. However, in the US, where vitamin A deficiency is rare, there's no solid evidence that vitamin A supplements reduce the severity or mortality of measles. Experts warn that while vitamin A might help, it cannot prevent measles like the vaccine can.

The MMR vaccine is incredibly effective. Two doses provide lifelong immunity for most people. Yet, vaccination rates are dropping. In Texas, where measles is spreading, only about 82% of kindergarteners have received the vaccine. Nationally, MMR coverage among kindergarteners has fallen below the 95% threshold needed for herd immunity.

Critics argue that focusing on vitamins and nutrition overlooks the proven effectiveness of vaccines. While a healthy lifestyle boosts the immune system, it's not enough to stop measles from infecting unvaccinated individuals. Measles can cause serious complications, including deafness, lung scarring, and brain damage. Before the vaccine, these complications were all too common.

Experts urge caution with vitamin A supplementation. It's possible to overdose, and it should only be given under medical supervision. Cod liver oil, mentioned as a source of vitamin A, does not contain enough to be effective.

The push for vitamins and nutrition as alternatives to vaccines is not new. Some anti-vaccine groups have long promoted this idea. However, experts stress that vaccines are safe and effective. The misinformation spread by anti-vaccine groups has led to increased vaccine hesitancy and more outbreaks of preventable diseases.
