Elk Grove Village, IL—(ENEWSPF)—October 21, 2013. In the U.S., children receive the first recommended dose of measles, mumps and rubella (MMR) vaccine between 12 and 15 months of age; in Canada, the first dose is recommended at age 12 months. A new study in the November 2013 Pediatrics (published online Oct. 21) found children in Canada who had received their first dose of MMR vaccine at age 15 months had a higher level of immunity to measles than children who received their first dose at age 12 months.
