Legacy Measles Vaccines from ’70s and ’80s May Be Wearing Off, Doctors Warn
As the current measles outbreak in Florida continues to spread, doctors are warning that individuals who were vaccinated for measles in the 1970s or ’80s may no longer be fully protected. The measles vaccine was first introduced in 1968, with the MMR vaccine following in 1971, providing protection against measles, mumps, and rubella.
According to USF College of Public Health associate professor Jill Roberts, individuals who received measles vaccinations in the ’70s and ’80s, mainly those in their 40s and 50s now, should check with their healthcare provider about their immune status. Roberts emphasized that there is no risk in getting another MMR vaccine if needed, as they are inexpensive and widely available.
Dr. Jacob Glanville, a virology expert, advised individuals who have received the MMR vaccine to talk to their doctor about a measles titer test to measure their level of immunity. Dr. Marc Siegel, a clinical professor of medicine, stressed the importance of measles vaccinations, especially with the current surge of measles cases globally.
As of February 29, a total of 41 measles cases had been reported in 16 U.S. jurisdictions. The Centers for Disease Control and Prevention (CDC) continues to monitor the situation closely.
