Get started with v-safe.
Use your smartphone to tell CDC about any side effects after getting the COVID-19 vaccine. You’ll also get reminders if you need a second vaccine dose.
V-safe is a smartphone-based tool that uses text messaging and web surveys to provide personalized health check-ins after you receive a COVID-19 vaccine. Through v-safe, you can quickly tell CDC if you have any side effects after getting a COVID-19 vaccine. Depending on your answers to the web surveys, someone from CDC may call to check on you and get more information. V-safe will also remind you to get your second COVID-19 vaccine dose if you need one.
Note: V-safe cannot schedule COVID-19 vaccination appointments, nor serve as an official record of being vaccinated against COVID-19. You will receive a COVID-19 vaccination card at your vaccination appointment. Click here to learn more about COVID-19 vaccination cards, including what to do if you lost or did not receive your card.
If you need to schedule, reschedule, or cancel a COVID-19 vaccination appointment, contact the location that set up your appointment or a vaccination provider in your area. This may be your state or local health department, employer, or vaccination provider.
V-safe does not provide medical advice. If you have symptoms or health problems that concern you at any time following COVID-19 vaccination, please contact your healthcare provider. In addition, if you have not been able to report your post-vaccination experience in v-safe (because of a missed or expired health check-in), you can also report adverse events after vaccination to the Vaccine Adverse Event Reporting Systemexternal icon.
