The first Americans to receive a Covid-19 vaccine could get it as soon as 11 December, according to the head of the US coronavirus vaccine programme.
Dr Moncef Slaoui told US network CNN the plan was to “ship vaccines to the immunisation sites within 24 hours” of a vaccine being approved.
The comments come amid a surge in coronavirus cases across the country.
These are the highest tolls registered anywhere in the world, BBC reported.
American pharmaceutical company Pfizer and its partner BioNTech submitted an application on Friday for emergency authorisation in the US of their Covid-19 vaccine.
The vaccine, which requires two doses, has been shown by tests to be 95% effective. Pfizer hopes to produce up to 50 million doses by the end of the year.
A Food and Drug Administration (FDA) vaccine advisory committee is set to meet on 10 December to discuss whether to authorise the vaccine.
