Biden says biggest vaccine donation 'supercharges' battle against coronavirus

U.S. President Joe Biden said on Thursday that a donation of 500 million doses of the Pfizer COVID-19 vaccine to the world's poorest countries would supercharge the battle with the virus and comes with 'no strings attached.' Biden, speaking alongside Pfizer Chief Executive Albert Bourla in the English seaside resort of Carbis Bay ahead of a G7 summit, thanked other leaders for recognising their responsibility to vaccinate the world.
