What is V-safe?

V-safe is a vaccine safety monitoring system that lets you share with CDC how you or your dependent feel after getting a participating vaccine.

After you register, V-safe will send you personalized and confidential health check-ins via text messages or emails to ask how you feel after vaccination. Completing health check-ins and sharing how you feel, even if you don’t experience side effects after vaccination, helps CDC’s vaccine safety monitoring efforts and lets others know what to expect in the days and weeks following vaccination.

V-safe originally launched in December 2020 to monitor the safety of COVID-19 vaccines and later expanded to include mpox vaccines. Since its launch, 10.1 million V-safe participants completed more than 151 million health surveys about their experiences following COVID-19 and mpox vaccination, and V-safe data have been included in more than 20 scientific publications. V-safe is one of several complementary safety systems CDC uses to closely monitor the safety of vaccines in the United States. It lets vaccine recipients self-report how they feel after receiving a vaccine.

Which vaccines are being monitored in V-safe?

• Respiratory Syncytial Virus (RSV) vaccines for older adults (aged 60 and older)
