Get vaccinated. Get your smartphone. 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 an additional dose.

v-safe Overview


V-safe is a smartphone-based tool that uses text messaging and web surveys to give 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.

This information helps CDC monitor the safety of COVID-19 vaccines in near real time. Depending on your answers to the v-safe questions, someone from CDC may call to check on you or your child and get more information. V-safe will also remind you to get additional COVID-19 vaccine doses if you or your child needs one.

Parents and guardians can enroll children ages 5 years and older in v-safe and complete health check-ins on their behalf after they have been vaccinated for COVID-19. All family members who are eligible to be vaccinated can be enrolled in v-safe. Parents and guardians should use their smartphone to complete a separate v-safe registration for each child. All v-safe communications will be sent to the parent’s or guardian’s smartphone.

If you are enrolled in v-safe and report that you were pregnant at the time of vaccination or after vaccination, the CDC COVID-19 Pregnancy Registry staff* might contact you to learn more. If you choose to enroll in the registry, you will be contacted several times throughout your pregnancy for additional health check-ins.
