December 14, 2020

V-safe is a smartphone-based tool developed by the CDC that uses text messaging and web surveys to conduct electronic health check-ins with participants who have received a COVID-19 vaccine.

Electronic Health Check-Ins

Electronic health check-ins will take place:

  • Daily for first week post-vaccination
  • weekly thereafter until 6 weeks post-vaccination
  • additional checks at 3-, 6-, and 12-months post-vaccination

Electronic health check-ins will:

  • Provide an opportunity for participants to report any side effects or health problems after COVID-19 vaccination.
    • If reports result in significant health impact, the CDC will follow-up by phone and create a VAERS report if appropriate.
  • Capture information on pregnancy status and enable follow-up on pregnant women.
  • Remind participants when it is time to get their second dose of COVID-19 vaccine if needed.

Participation in V-Safe is voluntary and patients can opt out at any time. Consider placing V-Safe posters and materials in clinic rooms and locations where the COVID vaccine may be administered.
