The Centers for Disease Control and Prevention (CDC) is urging anyone born between 1957 and 1971 to get vaccinated against the measles, even if they already got the shots.

Health officials say this vaccination or re-vaccination against measles might be necessary because someone born during that time period may have missed out on getting the shot when they were younger.

Someone born after 1957 and before 1971 may have hit the gap of time where the vaccine was not available and when they were considered too old to need the vaccine shot after it was available. Health officials urge people born during that time to pay close attention to their medical records.

Also, anyone in this 'vaccine gap' is enouraged to speak with their primary care physician to decide what options are best for them.
