COVID-19 vaccines from Pfizer Inc and Moderna Inc could be ready for United States authorisation and distribution within weeks, setting the stage for inoculation to begin as soon as this year, US Health and Human Services Secretary Alex Azar said on Wednesday.
Pfizer says it will request an emergency use authorisation from the US Food and Drug Administration for its COVID-19 vaccine in the coming days.
It has shown consistent results across broad demographics with no major side effects.
