The vaccine is the first in the US to be approved for emergency use and will arrive at sites across the country starting on Monday.

The first doses of Pfizer-BioNTech’s COVID-19 vaccine were being shipped from a factory in Michigan on Sunday.

Experts say the death toll is a grim reminder to follow restrictions despite optimistic inoculation outlook.

Moncef Slaoui, head of a federal vaccine development programme, says the first vaccines could be shipped by mid-December.

US Health and Human Services secretary says the vaccines could possibly be used for inoculation as soon as this year.

The US president also continued to insist, without any evidence, that he won the presidential election.
