You must be a Trumper if you asked if the Vitamin A used for measles started by Feb.. The statement was made by RFk to use Vitamin A for measles, so obviously they are checking on it when he took office. My children are all older, I never heard any doctor ever say to take Vitamin A for measles. Fortunately my children had the vaccine. Vaccine worked fine did not have any effects from it. Bottom line children should have vaccines!!!
