If medical trials go effectively and the Food and Drug Administration approves it, younger youngsters may get vaccinated by the top of the yr, BioNTech o-founder and chief medical officer Dr. Ozlem Tureci mentioned late Thursday.
“We anticipate the information on the finish of the summer time or autumn of this yr. We will then file it with the regulators and, relying on how briskly they react, by the top of the yr we would get approval to additionally immunize youthful youngsters,” she mentioned.
In late March, Pfizer and BioNTech began a clinical trial testing their vaccine on wholesome 6-month to 11-year-old youngsters, a vital step in acquiring federal regulatory clearance to start out vaccinating younger children and controlling the pandemic.
