COVID-19: America to give 500 million Pfizer coronavirus jabs to poorer countries

The US is to distribute half a billion shots of the Pfizer vaccine to 100 other countries.

Some 200 million doses will be given out this year and 300 million in 2022.

It comes as US President Joe Biden said before leaving for the G7 summit in Cornwall that he would be announcing a vaccine strategy for the world.

The US would pay for the doses at a "not-for-profit" price, according to the New York Times, which said the plan could be officially announced on Thursday.

America is well advanced in its vaccine rollout but campaigners have called for richer countries to do more to help protect developing nations.
