How can I participate in v-safe?

Once you get a COVID-19 vaccine, you can enroll in v-safe using your smartphone. Your healthcare provider will give you an information sheet on v-safe that explains how to register and get started. V-safe is free to use — you will need a smartphone with a modern browser and access to the internet to participate. Participation is voluntary and you can opt out at any time. To opt out, simply text “STOP” when v-safe sends you a text message. You can also start v-safe again by texting “START.”

If you would like to participate in v-safe, you must sign up within 42 days of getting your first COVID-19 vaccine dose.

How long do v-safe check-ins last?

During the first week after you get your vaccine, v-safe will send you a text message each day to ask how you are doing. Then you will get check-in messages once a week for up to 5 weeks. The questions v-safe asks take less than 5 minutes to answer.

If you need a second dose of vaccine, v-safe will provide a new 6-week check-in process so you can share your second-dose vaccine experience as well. Finally, you’ll receive check-ins 3, 6, and 12 months after your final dose of vaccine.

Is my health information safe?

Yes. Your personal information in v-safe is protected so that it stays confidential and private. To the extent vsafe uses existing information systems managed by CDC, FDA, and other federal agencies, the systems employ strict security measures appropriate for the data’s level of sensitivity.

How does my participation in v-safe make a difference?

By participating in v-safe, you can tell CDC if you have any side effects after a COVID-19 vaccine. This information helps CDC monitor the safety of COVID-19 vaccines in near real time. If any serious health problems are reported, they can be quickly investigated by CDC’s medical experts and scientists. In addition, traditional vaccine safety systems, such as Vaccine Adverse Event Reporting Systemexternal icon (VAERS) and the Vaccine Safety Datalink (VSD), will also be used to monitor the safety of COVID-19 vaccines. These systems are part the nation’s comprehensive approach to vaccine safety.

What if I have a health problem I think is related to my COVID-19 vaccination between v-safe check-ins or after I’ve finished v-safe?

If at any time you have symptoms or health problems following COVID-19 vaccination that concern you, please contact your healthcare provider. In addition to your participation in v-safe, you can also report your experience to VAERSexternal icon.
