US FDA Authorizes Pfizer-BioNTech COVID-19 Vaccine for Emergency Use in Adolescents

•The US Food and Drug Administration expanded the emergency use authorization (EUA) for the Pfizer-BioNTech COVID-19 Vaccine on May 10, 2021 to include adolescents aged between 12 and 15 years. 

•The FDA amended the emergency use authorisation given initially to the vaccine manufacturer in December 2020 for administration in individuals aged 16 years and older.

The World Health Organisation had listed the Moderna COVID-19 vaccine (mRNA 1273) for emergency use on April 3-, 2021, becoming the fifth vaccine to receive WHO's emergency validation.

The WHO’s Emergency Use Listing (EUL) assesses the quality, safety and efficacy of COVID-19 vaccines before including them in the list. It is a prerequisite for COVAX Facility vaccine supply. 

WHO’s Strategic Advisory Group of Experts on Immunization (SAGE) had reviewed the vaccine earlier in January 2021 and had recommended the vaccine for all aged 18 years and above in its interim recommendations.   

Moderna's COVID vaccine had received emergency use authorization from the US Food and Drug Administration on December 18, 2020. The European Medicines Agency had granted the vaccine a marketing authorisation that would be valid throughout the European Union on January 6, 2021. 

Vaccinating children and adolescents has become a prime focus now, as according to experts it will help in raising the overall immunity of the country given that herd immunity is unlikely to be achieved due to rising COVID-19 variants.
