Of the 203 million people who have received at least one dose of a covid-19 vaccine, more than 9 million have enrolled in a program to share information about their health since getting the shot.
The initiative was created for the covid-19 vaccines to complement the Centers for Disease Control and Prevention’s vaccine safety monitoring system. Known as v-safe, the registry lets inoculated people report their experiences, including serious suspected side effects, directly to the CDC through smartphones, adding to the data gathered from clinical trials and other safety monitoring systems.
