Many American adults are unsure of which measles vaccination they have received.

Adults who received the measles vaccine between 1963 and 1967 may not be protected from the virus, according to the Centers for Disease Control and Prevention (CDC). That's because when the measles vaccine became available in 1963, there were two versions and only one was effective.

The first version of the initial vaccine was inactivated, also known as the "dead" measles vaccine. The other version was the live attenuated vaccine against measles, which was a weakened form of the virus. The dead vaccine was discontinued in 1967, when it was determined that, in fact, it did not protect against measles virus infection.

In 1968, a new version of the live measles vaccine hit the market and is still in use today. Since 1971, the measles vaccine has been combined with the mumps and rubella vaccines in the MMR three-in-one vaccine.

If you were vaccinated between 1963 and 1967, but are not sure which version you received, you should try to check your vaccination records. Unfortunately, there is no national organization that keeps records of vaccination and can be difficult to track. & Nbsp;

If you do not have written documentation, or if you have not had a blood test to prove that you are immune, the CDC recommends biting the bullet and getting another dose or two. "MMR vaccine is safe, and there is no harm in getting it another dose if you are already immune to measles, mumps or rubella, "& nbsp; the agency says on its website.

A high risk for travelers

This year is on track to be the worst year for measles outbreaks in 27 years, according to CDC data. From January 1 to April 11, there were 555 confirmed cases of measles in 20 states.

In other parts of the world, there are & nbsp; currently & nbsp;outbreaks of measles& nbsp; in Brazil, Israel, Japan, Ukraine and the Philippines.

There have been several recent cases of travelers who have contracted and spread measles, including:

The CDC says that international travelers are at high risk for exposure and transmission of the virus and recommend the following:

  • Infants 6 months to 11 months of age should receive one dose of the MMR vaccine.Babies who receive one dose of the MMR vaccine before their first birthday should receive two more doses (one dose between 12 and 15 months of age and another dose at least 28 days later).
  • Children 12 months of age or older should receive two doses of MMR vaccine separated by at least 28 days.
  • Adolescents and adults who have no evidence of immunity against measles should receive two doses of the MMR vaccine separated by at least 28 days.

Risk assessment: When were you born?

Born before 1957? You probably have not been vaccinated against measles, but you are safe anyway. "Before the vaccines were available, almost all were infected with measles, mumps and rubella virus during childhood," according to the CDC website.

Most people born between 1957 and 1989 received only one dose of MMR. Frequently Asked Questions about Measles says that a dose of the measles vaccine is about 93% effective in preventing measles if exposed to the virus. Two doses are about 97% effective.

It was not until 1989 that health authorities began recommending two doses of the live vaccine. There was a recovery program in 1989, so some high school students were given the second shot at the time, but the guidelines varied according to the state.

The result: If you are not sure which measles vaccine you have received, or how many doses, it is better to be safe than sorry and roll up your sleeves.
