Pfizer has increased its production of COVID-19 vaccines and will deliver remaining doses to the US faster than expected, CEO Albert Bourla said on Twitter.
Bourla said his company would deliver 220 million doses of the vaccine by the end of May — 10% more than previously agreed on.
He said the complete supply of 300 million would be delivered by the end of July, two weeks earlier than expected.
"In the fight against COVID-19, we're in this together," he wrote.
The announcement came after US officials recommended a pause on the use of the Johnson & Johnson vaccine, citing reports of blood clots forming in six people who received the shot.
