As Vaccinated Adults Continue to Spread Measles Many Question Real Reasons Behind N.Y. Ban on Unvaccinated Children in Jewish Communities

Gregory A. Poland, MD, and Robert M. Jacobson, MD, both of the Mayo Clinic, authored the study and revealed that a high percentage of individuals in measles outbreaks were already vaccinated.

Despite the above gains measles is reemerging as a serious public health threat, and outbreaks are occurring even in highly developed countries where vaccine access, public health infrastructure, and health literacy are not significant issues.

This is unexpected and a worrisome harbinger – measles outbreaks are occurring where they are least expected.

As illustrated in the Table, since 2005 these outbreaks have also occurred in the U.S.—with surprising numbers of cases occurring in persons who previously received one or even two documented doses of measles-containing vaccine. (Source.)

Given the fact that the MMR vaccine is a “live” virus vaccine where the vaccinated individual can be contagious for up to 30 days, could the mass vaccination campaign be a contributing factor in the measles outbreaks?

The MMR vaccine package insert found on the FDA.gov website states:

Excretion of small amounts of the live attenuated rubella virus from the nose or throat has occurred in the majority of susceptible individuals 7 to 28 days after vaccination.
