U.S. regulators on Monday expanded the use of Pfizer’s COVID-19 vaccine to children as young as 12, offering a way to protect the nation’s adolescents before they head back to school in the fall and paving the way for them to return to more normal activities.
Shots could begin as soon as a federal vaccine advisory committee issues recommendations for using the two-dose vaccine in 12- to 15-year-olds. An announcement is expected Wednesday.
Most COVID-19 vaccines worldwide have been authorized for adults. Pfizer’s vaccine is being used in multiple countries for teens as young as 16, and Canada recently became the first to expand use to 12 and up. Parents, school administrators and public health officials elsewhere have eagerly awaited approval for the shot to be made available to more kids.
The Food and Drug Administration declared that the Pfizer vaccine is safe and offers strong protection for younger teens based on testing of more than 2,000 U.S. volunteers ages 12 to 15. The study found no cases of COVID-19 among fully vaccinated adolescents compared to 18 among kids given dummy shots. More intriguing, researchers found the kids developed higher levels of virus-fighting antibodies than earlier studies measured in young adults.
The younger teens received the same vaccine dosage as adults and had the same side effects, mostly sore arms and flu-like fever, chills or aches that signal a revved-up immune system, especially after the second dose.
Experts say children must get the shots if the country is to vaccinate the 70% to 85% of the population necessary to reach what is called herd immunity.
In the meantime, the Centers for Disease Control and Prevention says unvaccinated people, including children, should continue taking precautions such as wearing masks indoors and keeping their distance from other unvaccinated people outside of their households.
