Study Supported by Doris Duke Foundation Reveals Mumps Resurgence Due to Waning Vaccine Protection in Adults
In the study, which was published in Science Translational Medicine, the researchers pooled and analyzed 6 epidemiological studies of mumps vaccine effectiveness conducted over past decades in the United States and Europe. The researchers estimated that vaccine-derived immune protection against mumps wanes on average 27 years after vaccination, with 25% of individuals in the United States vaccinated losing protection within 7.9 years, 50% within 19 years, and 75% within 38 years.
The researchers concluded that routine use of a third vaccine dose at 18 years of age, or booster dosing throughout adulthood, may be one strategy to prevent mumps re-emergence...
