A new study published in the December issue of ‘Pediatrics’ found that nearly one-third of mumps cases in the United States are in pediatric patients, many of whom are vaccinated.
The study found that from 2007-2009, 9,172 pediatric cases of the mumps were reported, with 87% of those patients having received at least one vaccination before getting sick.

Experts said they are not sure why vaccinated people are getting the mumps, but factors that could affect immunity include a lack of prior exposure to the virus, waning immunity, and the circulation of genotypes the vaccine does not contain, NBC News reported.
The mumps vaccine was introduced in 1967, and according to experts caused a >99% reduction in cases in the U.S.
Mumps is best known for causing puffy cheeks and a tender swollen jaw and is caused by a contagious virus. Mumps is spread through direct contact with saliva or other respiratory droplets, per the Centers for Disease Control and Prevention. Infected persons can spread mumps before any swelling shows.
Despite the new study, the CDC emphasized the best way to protect yourself from getting the mumps is to get a vaccination.
