Adult and Maternal Vaccination Trends in the U.S.

Why Vaccinations Matter:

Vaccines offer the best protection against infectious respiratory diseases that cause severe illness, hospitalization, and death. Yet, recent data from IQVIA shows that many adults and pregnant women are missing key recommended vaccinations, including those that protect against flu, COVID-19, RSV, pneumococcal disease, and Tdap.

Data Sources:
The data reflect patient-level insights from both private and public insurance plans across all U.S. states, representing 258 million people ages 18+. It draws from IQVIA administrative claims data and incorporates retail pharmacy sales data to provide a more complete picture of vaccination behavior and access.
