According to the study, published this week in JAMA Pediatrics, if just 5 percent fewer children in the 2-11 age range were inoculated against the measles, mumps and rubella (the MMR vaccine), the number of annual measles cases among that group would triple. That would raise public health costs by at least $2.1 million a year, according to…
