CDC recommends vitamin A for measles amid outbreak in Texas

In the United States, a significant measles outbreak occurred in western Texas, affecting 146 individuals and tragically resulting in the death of one school-aged child. Amid this public health crisis, the Centers for Disease Control and Prevention (CDC) released its initial public statement regarding the outbreak, highlighting the potential use of vitamin A as a form of supportive care for those afflicted. The statement emphasized that measles does not have a specific antiviral treatment, which gives rise to the importance of supportive care in managing symptoms and complications associated with the illness. For numerous years, vitamin A has been administered in severe cases of measles, particularly in developing countries where vitamin deficiencies are prevalent. Studies have demonstrated that children with lower levels of vitamin A experience more severe symptoms and outcomes when infected with measles. Experts like Dr. Camille Sabella from Cleveland Clinic Children’s Hospital welcomed the CDC's endorsement, especially given the evidence from cases in resource-limited settings. However, in the United States, the application of vitamin A in measles cases is far less common due to the relatively adequate vitamin A levels in the general diet of Americans. Moreover, health professionals have expressed caution when implementing vitamin A in the U.S. A significant factor behind the underutilization of vitamin A for measles treatment in developed countries arises from the understanding that a higher prevalence of vitamin A deficiency exists in lower-income regions. Experts, including Dr. Alexandra Yonts from Children’s National Hospital, have noted the uncertainty regarding the effectiveness of vitamin A in American populations, where levels of the vitamin are typically sufficient, unlike in developing nations. Despite the unclear benefits, experts like Dr. Bernard Camins acknowledge the minimal risks associated with appropriate dosages of vitamin A for measles patients. However, it is critical to emphasize that vitamin A should never be considered a substitute for the Measles, Mumps, and Rubella (MMR) vaccine. Educators and health care professionals have voiced concerns regarding misinformation, particularly from anti-vaccine proponents who may incorrectly advocate vitamin A as a preventative measure rather than the vaccine. The WHO, CDC, and AAP outline specific dosing protocols for vitamin A in measles cases, recommending application solely in rare, extreme circumstances under medical supervision to prevent toxicity and potential adverse health effects.
