Vaccination Rates

LIke ThisLIke ThisLIke ThisLIke ThisLIke This

When it comes to vaccinating children, we support and follow the recommendations of the American Academy of Pediatrics (AAP), the leading professional organization for pediatricians. We advise all families to immunize their children according to the AAP's schedule, and we strive for 100% vaccine coverage among children who visit our primary care practice.

Published research and our own firsthand experience have shown us that immunization helps protect children from many common infections, which in some cases can lead to serious and even life-threatening complications. Immunization also prevents children from passing these infections on to others, including their parents and other family members.

How are we doing?

We track the immunization rates of children between the ages of 2 and 3 who are seen in our Primary Care Center, which provides general pediatric care to more than 12,000 infants, children and young adults each year. Our annual vaccination rates hover between about 86 percent and 92 percent — higher than the national average and the rate for Massachusetts as a whole (as estimated by the Centers for Disease Control and Prevention):

If we exclude children whose parents refused vaccinations for religious or personal reasons or who came into the practice after age 1 (after many vaccines are given), our coverage rate rises, to a little under 90 percent:

What are we doing to improve?

We're making an effort to identify children who are not up-to-date on their vaccinations as early as possible, paying special attention to those between the ages of 15 and 23 months — an age range in which children frequently miss vaccines. We've also begun closely tracking why children fall behind on their vaccines in the first place, to learn more about how to prevent it from happening.

How do we compare to other hospitals?

Not all hospitals share their immunization rates, so it's not possible to directly compare our rates with those of other children's hospitals. However, the Massachusetts and national averages, which lump together a range of hospitals and other health care providers, offer a good benchmark for judging our performance.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
