Lifestyle Health FDA Grants Emergency Use Authorization of Pfizer COVID Booster for Kids 5 to 11 Children ages 5 to 11 will be eligible for a third dose of Pfizer’s COVID-19 vaccine if it has been at least five months since their second dose By Vanessa Etienne Vanessa Etienne Twitter Vanessa Etienne is an Emerging Content Writer-Reporter for PEOPLE. People Editorial Guidelines Published on May 17, 2022 03:36PM EDT Share Tweet Pin Email Photo: Getty The U.S. Food and Drug Administration has granted emergency use authorization of a booster dose of Pfizer and BioNTech's coronavirus vaccine for children ages 5 to 11. The agency announced authorization on Tuesday after the companies submitted the application in late April following a study that showed children under 12 had a "strong immune response" from a third dose of their COVID vaccine. A booster shot after at least five months is believed to raise Omicron-fighting antibodies by 36 times. "While it has largely been the case that COVID-19 tends to be less severe in children than adults, the omicron wave has seen more kids getting sick with the disease and being hospitalized, and children may also experience longer term effects, even following initially mild disease," Dr. Robert Califf, FDA Commissioner, said in a release. "The FDA is authorizing the use of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine for children 5 through 11 years of age to provide continued protection against COVID-19."

More than 8 million children in the age group in the U.S. have already received the first two doses of the vaccine. "The Pfizer-BioNTech COVID-19 Vaccine is effective in helping to prevent the most severe consequences of COVID-19 in individuals 5 years of age and older," said Dr. Peter Marks, director of the FDA's Center for Biologics Evaluation and Research. "The FDA has determined that the known and potential benefits of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine for children 5 through 11 years of age at least five months after completing a primary series outweigh its known and potential risks and that a booster dose can help provide continued protection against COVID-19 in this and older age groups." The Pfizer vaccine is the only COVID vaccine authorized for use in the U.S. for children ages 5 to 11. Unvaccinated kids aged 5 to 11 years old were more than twice as likely to end up in the hospital with COVID-19 during the omicron surge than vaccinated kids, according to a report from the CDC. And since last November when Pfizer's COVID-19 vaccine was approved for use in 5 to 11 year olds, the majority of hospitalizations — 9 in 10 — were in kids who were unvaccinated, the CDC reported.
