The only Americans not eligible for Coronavirus Vaccines – babies, toddlers and preschoolers – may soon be eligible, after an advisory panel to the FDA voted unanimously to recommend Pfizer and Moderna vaccines. Here’s what we know so far.

An advisory panel at the Centers for Disease Control and Prevention is expected to meet Friday following the unanimous vote to discuss whether they will endorse the shots. According to experts, there are roughly 18 million children in that age group and the CDC Director would need to sign off before they can begin getting their shots.

One panel member, Dr. Jay Portnoy of Children’s Hospital in Kansas City, Missouri, said, “This is a long awaited vaccine, there are so many parents who are absolutely desperate to get this vaccine and I think we owe it to them to give them a choice to have the vaccine if they want to.”

Pfizer and BioNTech announced in December a two-dose regimen did not create enough of an immune response in some children under 5, prompting their study of a third dose.

Pfizer’s vaccine for children should be given in three shots and Moderna’s in two at slightly different dosages.
