According to experts, it seems imminent that news channels will be reporting on the first U.S. infant death from measles in almost 40 years. Will the recent measles outbreak increase or decrease non-medical vaccine exemption rates? I've heard arguments for and against vaccines from parents across the U.S. All of them, regardless of their viewpoint, want the best for their child. The efficacy of the vaccine is rarely called into question by parents. For those interested, the CDC says "Two doses of measles vaccine are about 97% effective at preventing measles if exposed to the virus. One dose is about 93% effective." ( Instead, top concerns about the measles vaccine recently reported in the news include: it may cause autism; potential for serious, though very rare, adverse reactions; religious reasons; and belief that measles is not a very serious illness. Regardless of a parent's decision for or against the vaccine, there is a relatively high probability that the first infant death from measles in the U.S. will occur in an infant too young to receive their first vaccine dose and before the parents are ever presented with the opportunity to decide for or against it.
