Sir Sandy Macara, former chairman of the British Medical Association, believes that children should only be allowed to start school if they have been vaccinated against measles, mumps and rubella, i.e. had the MMR jab.

News stories about an allegedly harmful link between the mumps, measles and rubella vaccine and the onset of autism had little effect on whether U.S. parents immunized their children, according to a review of immunization records and news stories. Parents’ decisions were more likely influenced by recommendations from their child’s pediatrician, the researchers said.
