CDC director says all kids — vaccinated or not — should be back in class by September

School attendance should fully be in person as of September, Centers for Disease Control and Prevention Director Rochelle Walensky said on Wednesday.

What are the details?

The nation's children should be attending physical school classes in September, Walensky said during an interview with ABC News, whether they are vaccinated or not.

"We should anticipate, come September 2021, that schools should be full-fledged in person and all of our children back in the classroom," she said in her remarks on school reopenings. "We can vaccinate teachers, we can test, there's so much we can do."

She added that children over the age of 12 years should be eligible for Pfizer's COVID-19 vaccine by mid-May, so long as the Food and Drug Administration approves the biopharmaceutical company's application for emergency use.

According to the outlet, Walensky said she also "expects Moderna will soon follow Pfizer because those studies are currently underway."

"She said she is hopeful that by summertime there will be two vaccines available for children 12 and up," the outlet reported. "Johnson and Johnson is expected to start their pediatric trials in the months ahead."

What else?

In late March, Pfizer released data showing its COVID-19 vaccine 100 percent effective in children as young as 12 years old.

At that time, Pfizer CEO Albert Bourla said that the company hopes to use the vaccine on that age group ahead of the 2021-2022 school year.

"We share the urgency to expand the authorization of our vaccine to use in younger populations and are encouraged by the clinical trial data from adolescents between the ages of 12 and 15," Bourla said in a statement.

Earlier in March, Pfizer-BioNTech embarked on a global study to test its vaccine in children ages 6 months to 11 years.
