President Donald Trump on Monday signed an executive order that could substantially alter the childhood vaccine schedule in the United States. Among other things, the order calls for the measles, mumps, and rubella vaccine to be given as three separate shots, says childhood vaccines should be spread out between medical visits as much as possible, directs healthcare officials to invest further efforts into studying the effects of the current schedule on children‘s health, and calls for more research into alternative adjuvants outside of aluminum.

It would appear that directives such as these, as they relate to the MMR vaccine, are based on what is largely a moot point, as numerous studies have put major dents in the notion that the MMR vaccine itself has anything to do with the increase in the incidence of autism.
