WASHINGTON (AP) — The White House says the Biden administration is already assembling and shipping millions of doses of the COVID-19 vaccine for children ages 5-11. The first shots could go into kids’ arms by midweek, and the U.S. has enough vaccine for all 28 million children in the age bracket.

On Tuesday, a special advisory panel to the Centers for Disease Control and Prevention will meet to consider detailed recommendations for administering the Pfizer-BioNTech vaccine to younger children. The Food and Drug Administration already cleared the shots.

After CDC advisers make their recommendations, agency director Dr. Rochelle Walensky will give the final order.
