Study: Immunocompromised patients report fewer negative effects after COVID-19 mRNA vaccine booster

Immunocompromised people age 12 and older experience fewer local and systemic reactions after receiving a COVID-19 mRNA booster than after the third primary dose, the Centers for Disease Control and Prevention reports. The findings are based on responses to CDC’s voluntary V-safe virtual health check-in platform and Vaccine Adverse Event Reporting System.
