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 v-safe will send you check-in messages once a week for up to 6 weeks. The questions v-safe asks take less than 5 minutes to answer.

After you enter another dose of vaccine, v-safe will restart the check-in process so you can share your experience after this dose as well. Finally, you’ll receive check-ins 3, 6, and 12 months after your final dose of vaccine.

The v-safe system sends all participants a follow up text message to see if they received a booster dose of COVID-19 vaccine. Getting a v-safe text message about a booster dose does not necessarily mean that you need a booster dose. Check CDC’s current recommendations about who should consider getting a booster dose of COVID-19 vaccine: Who Is Eligible for a COVID-19 Vaccine Booster Shot?

Is my health information safe?

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

What is the v-safe COVID-19 Vaccine Pregnancy Registry?

The v-safe COVID-19 Vaccine Pregnancy Registry collects health information from people who receive COVID-19 vaccines shortly before or during pregnancy. Participation in the v-safe COVID-19 Vaccine Pregnancy Registry is voluntary. This information helps CDC monitor the safety of COVID-19 vaccines in people who are pregnant. Learn more about COVID-19 vaccination considerations for people who are pregnant or breastfeeding.

How can I participate in the v-safe COVID-19 Vaccine Pregnancy Registry?

CDC is inviting people who received COVID-19 vaccination in the periconception period (within 30 days before the last menstrual period before the pregnancy) or during pregnancy to participate in the v-safe COVID-19 Vaccine Pregnancy Registry. The information is critical to helping people and their healthcare providers make informed decisions about COVID-19 vaccination. Participation is voluntary, and participants may opt out at any time.

The v-safe COVID-19 Vaccine Pregnancy Registry is for v-safe participants who self-identify as pregnant at the time of vaccination or shortly thereafter (within 30 days of vaccination). If you are enrolled in v-safe and report that you were pregnant at the time of vaccination or after vaccination, the 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.

During these check-ins, you will be asked questions about your pregnancy and medical history. After delivery, you might be contacted when your baby is about three months old. The registry staff will also ask for permission to review your medical records to get a more comprehensive picture of your pregnancy and your infant’s health. Personal information and responses in v-safe are confidential and will be protected to the full extent allowed by law.

Note: Participants are not paid for their participation, and not all people reporting pregnancy will be contacted to participate.
