"We should anticipate, come September 2021, that schools should be full-fledged in person and all of our children back in the classroom," the CDC director told ABC News Chief Medical Correspondent Dr. Jennifer Ashton during an Instagram Live conversation on ABC News. She said that parents and teachers should anticipate this regardless of whether children are vaccinated or not. "We can vaccinate teachers, we can test, there's so much we can do," she said. Asked when she expects children will become eligible to get vaccinated, Walensky said by mid-May. Pfizer recently released promising data indicating its vaccine is safe and effective for children ages 12 to 15.
