Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said he hopes there will be data to support Covid-19 vaccinations for older children by the late spring or summer.

“I am hoping we will have the data to support initiating COVID-19 immunizations for children (beginning with older children ages 12-17) by late spring or summer. We will progress to younger age groups as we have more data. This will help reduce virus transmission,” he tweeted from the White House Covid-19 Response Team account during a question and answer session.

When asked if it’s safe for children to go about their lives if all adults are vaccinated but children aren’t, Fauci said that “the situation in your community is a key factor here,” adding that while virus levels are high in the community, everyone needs to take steps such as wearing masks and social distancing.
