Measles Vaccination Rates Drop After COVID-19 Pandemic in Counties Across the US
- In 2025, measles outbreaks surged across the U.S., with over 1,000 cases reported in 33 states, raising health concerns nationwide.
- These outbreaks coincided with a decline in MMR vaccination coverage among children, which decreased by approximately 2.7 percentage points—from nearly 94% before the pandemic to just over 91% afterward—heightening susceptibility to measles.
- Researchers led by Lauren Gardner of Johns Hopkins analyzed data from over 2,000 counties, finding more than three-quarters reported vaccine declines while a few states showed increases.
- The CDC confirmed 1,088 cases with three deaths and warned that "vaccination rates are falling below the herd immunity threshold," urging all travelers to get vaccinated.
- If vaccination declines continue, experts caution measles could return at epidemic levels, prompting efforts like Arizona’s school vaccine clinics to raise immunization coverage.
