Pfizer and Moderna have formally asked U.S. regulators to grant emergency authorization for new COVID-19 vaccine boosters for children as young as five.

Pfizer and its partner BioNTech submitted a request to the U.S. Food and Drug Administration (FDA) on Sept. 26, several days after Moderna submitted a request to the FDA.
