The US Food and Drug Administration said children between the ages of 12 and 15 could be vaccinated.
US regulators have allowed the use of the Pfizer/BioNTech vaccine for vaccinations of children aged 12 and older, thus expanding vaccination in the country.
Previously, the vaccine became available to everyone over the age of 16. Two other vaccines approved for use in the United States, Moderna, and Johnson & Johnson, are not yet available to minors as research continues.
The vaccine manufacturers said they launched the approval process for the new age group last week.
The US Food and Drug Administration (FDA) said it is amending emergency drug authorization rules to include millions of children between the ages of 12 and 15 in the COVID-19 vaccination program.
