Dear Dr. Sue: I read your article on MMR vaccine recently (mumps, measles, rubella). I read the information related to infants, travel and the MMR vaccine but I wondered if I need to get an extra MMR? I am a high school student traveling to Peru this summer. Thanks! –Kristin

Hi Kristin: great question! There are many teens and college kids (like you) who may be travelingto a foreign country this summer.  Here are the recommendations.

If you are over 4 years of age and have had 2 doses of MMR, you are good to go for travel.

Most children/teens have received the first dose of MMR vaccine after their 1st birthday (12-15 months) and then again between 4-6 years of age. If the two doses of vaccine have been given, you are protected.

A good place to begin looking to see if you need any vaccine updates when you are planning an overseas trip is www.cdc.gov.   Click on the travel link. There you will find maps of the continents and you can click on the country you are visiting and go from there.

If there are outbreaks of disease in the area you are planning to visit, this site has the most recent information.  Try to look several months before your trip in order that you have time to get any vaccines that might be necessary. Keep checking as your trip approaches too.

Kristin, have a great trip, send us some pictures!
