First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at how well the yearly updated Pfizer COVID-19 vaccine works in adults and children. Instead of giving anyone the vaccine, researchers will analyze existing insurance claims and state vaccine records. They will compare people who got the vaccine to those who did not, tracking COVID-19 cases, hospital visits, and costs over six months.
