As of May 2, state officials say more than 5 percent of people vaccinated have only gotten one of the two doses they need to be fully vaccinated.

Using two different COVID-19 vaccines is a bit like giving the immune system two pictures of the virus, maybe one face-on and one in profile.

Austinites who are fully vaccinated can attend private indoor and outdoor gatherings, travel, dine and shop. Whether they’re advised to wear masks in these settings depends on the local COVID-19 situation.

The company said in late March that clinical trials showed the vaccine elicits "100% efficacy and robust antibody responses" in adolescents.

Locals are also brainstorming incentives, sending out emergency cellphone alerts, running clinics in workplace break rooms and hanging sign-up sheets in churches.

New coronavirus cases are at their lowest level since October. Some health experts think the vaccination campaign deserves credit for tamping down the U.S. outbreak. But will the downturn last?

NPR's Audie Cornish talks with pediatricians Nia Heard-Garris of Northwestern University and Jose Romero, Arkansas secretary of health, about what's safe and not safe to do with unvaccinated children.

Can I get a massage? Travel with my unvaccinated kids? Eat indoors at a restaurant? Hit the gym? Experts weigh in with advice on 16 frequently asked post-vaccination questions.

Researchers are trying to come up with tests that can be performed using a blood sample that will determine not only whether a COVID-19 vaccine will work but also for how long.
