As Mumps hit a 10-year-high, MMR’s lifelong protection may be false says MPH’s Schaffner
Mumps is on the rise in some parts of the U.S., and some public health professionals are wondering whether the current vaccine may be not quite up to the task. Our long-held assumption that the MMR's protection is lifelong may not be entirely true. After 10 to 15 years, effectiveness against the mumps may diminish, according to William Schaffner, M.D., a professor of preventive medicine at Vanderbilt University in Tennessee.
