We need to hear from you.
Today during our spring member drive, put a dollar value on the trustworthy reporting you rely on all year long. The local news you read here every day is crafted for you, but right now, we need your help to keep it going. In these uncertain times, your support is even more important. We can't hold those in power accountable and uplift voices from the community without your partnership. Thank you.

As the battle to defeat COVID-19 with vaccinations rolls on, one key part of the fight is tracking the immunizations’ safety -- and that’s where all of us can play a role. Once you get vaccinated, you can sign up for v-safe, an online tool you use to let the Centers for Disease Control and Prevention know how you’re doing.

It’s not an app -- and you need a smartphone to sign up and start using it. Here's how to register.

Since we’re still in the era of having only two-shot vaccines, here’s how it works:

After you get your first shot, v-safe will send you a text each day for a week asking whether you’re experiencing any side effects. The CDC says it takes less than five minutes to answer the questions in the survey. Then v-safe will check in once a week for up to five weeks.

Depending on your answers, someone from CDC may call to check on you.

After your second shot, v-safe will create another check-in process that will last six weeks. Then you’ll receive check-ins three, six, and 12 months after your final dose.

Getting a lot of people to participate in this process is important, because the more data the CDC collects, the clearer picture it can develop of a vaccine’s safety.

Have more questions? Here’s a CDC FAQ.

People experiencing side effects from a vaccination who don’t have a smartphone can submit a report to the Vaccine Adverse Event Reporting System (VAERS), which is managed by the CDC and the FDA. If you need additional help submitting a report, you can call the VAERS toll-free information line at 1-800-822-7967 or send an email to
