According to the Centers for Disease Control, people born before 1989 may need another measles vaccine.

The CDC recently announced that, in 1989, they changed their recommendations to include two doses of the MMR vaccine, which covers measles, mumps and rubella, making the vaccine more effective.

The CDC goes on to say those born in the late 60s-80s may have been vaccinated but never built an immunity because of the way the vaccines were administered.

Those who were vaccinated prior to 1989 should consult their doctor about whether or not a second vaccine is necessary.

The CDC recommends getting another vaccine as two doses are about 97 percent effective at preventing measles, while one dose is only about 93 percent effective.
