Pfizer's CEO on Friday said data about the effectiveness of its coronavirus vaccine in those under the age of five could be available by the end of the year.
CEO Albert Bourla spoke with NBC News chief White House correspondent Kristen Welker about the new data on Friday.
"We have a study in children six months to two years and then another cohort of children two to five years," Bourla said. "So [by] end of the year, beginning of next year, when we see the data, we will know more."
Pfizer has been at the head of the U.S.'s vaccine campaign as it is currently the only coronavirus vaccine to be approved for everyone above the age of five.
The announcement of data for those under the age of five comes as the new omicron variant has made its way to at least 10 states.
Scientists are still working to gather data on how effective the coronavirus vaccines will be against the new variant that has more than 30 different mutations.
Health experts are confident the vaccines will still be the best way to combat the new variant.
