Many parents around the U.S. are asking what to do about a possible measles exposure with a baby at home who is too young to be immunized. Should they stay home? Can they travel? Should they cancel that trip to Utah or to Vermont or even to Disney next month? Can they head out to the store without worry? Are they “safe?”
I hate that I can’t completely say they are safe. Measles is wildly contagious and during an outbreak it can spread, especially to older infants who aren’t vaccinated yet. The good news is that risk is low (more than 90% of us won’t get measles because we’re vaccinated so we also won’t spread it to you!). Some parents are also wondering about getting the vaccine before the baby turns 1 year because they’ve heard the recommendation for infants traveling abroad: infants traveling outside the U.S. are recommended to get an MMR (measles, mumps, rubella) shot if they are over 6 months of age (of note, babies who get the shot as an infant also get the usual shot again at 12 months of age). Without travel plans we wait to immunize babies with their first MMR vaccine until they are 12 months of age. Over 95% of babies who get the shot at 12 months of age are protected against measles and over 99% are protected for a lifetime after the 2nd dose (given at least 1 month later). Wow, right?
“This is not going to be the end-all-be-all post on protecting your infant or child from measles'” Dr Matthew Kronman, a pediatric infectious disease expert at Seattle Children’s, reminded me as we chatted today. Advice and guidance for protecting babies and children will change as we learn again how to protect our population from measles infection while unvaccinated pockets of people remain.
The CDC warns that the outbreak could grow (there’s over 100 cases in 14 states as of today) and nationally there’s a palpable dialogue going on between the herd (those immunized) and those not. Politicians are involved — Governor Christie talked today about “choice;” Obama is urging parents to immunize right along side the president of the American Academy of Pediatrics who released another urgent statement. Pediatricians, family docs, nurse practitioners and health workers everywhere are encouraging parents to get shots up-to-date to protect their own children and vulnerable populations (this includes infants). Here’s a bit of evidence and information that can hopefully curb anxiety for parents to babies. I teamed up with Dr Edgar Marcuse, a lifelong scholar with vaccines, former pediatrician at Seattle Children’s and an emeritus professor of pediatrics at University of Washington and Dr Matthew Kronman. Here are 7 tips about infants and families that may help shape your thinking: Read full post »
