Measles
Vaccination against measles with two doses is 97% effective, so people who are sure that they have received two doses do not need a booster. A person who received only one dose or is not sure if they received two doses should seek out a second dose in order to be fully protected. People born before the 70s or outside the US where a single dose of measles vaccine is routine may be affected.
The CDC recommends that all children receive the two dose MMR vaccine series, beginning at ages 12 to 15 months, followed by a booster dose at 4 to 6 years of age. Speak with your health care provider if you or your child is behind on vaccinations, has not been vaccinated, or if you are unsure of your vaccination status.
There are additional considerations for those traveling. While the recommendation has traditionally been that those traveling internationally should be fully vaccinated before such travel, with the recent rise in cases, this recommendation might be considered for any significant travel. Information on this guidance has been shared with providers statewide. To determine the action most appropriate for you or your child regarding travel, consult your health care provider or visit a public health clinic. The general travel recommendation has been that infants 6-11 months old receive one dose of the MMR vaccine before travel and then receive two more doses after their first birthday, so early notification to your provider about potential travel is best. Adults who are unsure of their vaccination status may be advised to receive one or two doses before they travel as well.
