Description:

Release Date: August 31, 2023

Includes COVID-19 vaccine effectiveness studies published through August 18, 2023

Note: Vaccine effectiveness estimates are not expected to change from month to month unless circulating variants significantly change. However, as more time has passed since COVID-19 vaccines have been introduced in the United States, scientists evaluate vaccine effectiveness relative to time since the most recent vaccine the person received to inform future recommendations.

This page highlights the most current and relevant CDC-authored vaccine effectiveness studies and will be updated with data, as well as key findings from the studies by age group. This page may also include a spotlight on one of the studies to explain more detail and context.
