Data shows the Pfizer and BioNTech COVID-19 vaccine is safe and effective for children ages 5 to 11, the companies announced Monday morning.

"We are eager to extend the protection afforded by the vaccine to this younger population, subject to regulatory authorization, especially as we track the spread of the delta variant and the substantial threat it poses to children," Pfizer chairman and CEO Albert Bourla said in a statement. "Since July, pediatric cases of COVID-19 have risen by about 240 percent in the U.S. -- underscoring the public health need for vaccination."
