Children and teens are less likely to need Covid-19 boosters, Fauci says. Here's why

(CNN) Now that the United States has rolled out Covid-19 booster shots for all fully vaccinated adults, some parents have been wondering if or when their vaccinated teenagers might need to get a booster dose of vaccine -- and researchers are working to have an answer soon.
Currently, a booster dose of the Pfizer/BioNTech or Moderna coronavirus vaccines are recommended for all adults who completed the original two-dose series of those shots at least six months ago, and a booster dose of the Johnson & Johnson vaccine is recommended for adults who completed a single shot at least two months ago.
"We don't know yet if children will need boosters.
But we are actively working on the study to answer that question," said Dr. Flor Munoz, a pediatric infectious disease specialist at Texas Children's Hospital, one of the sites in Pfizer's pediatric vaccine trials.
Munoz wrote in a text message to CNN on Thursday that "it is part of the study design to follow children at various time points after receiving two doses of vaccine."
