Until the very end of last year, no mRNA vaccine had ever been authorized and no such vaccine had ever been manufactured to scale by any company. Pfizer was part of Operation Warp Speed as a potential supplier for Covid-19 vaccines and had a purchase agreement for an initial 100 million doses. Pfizer's global goal is 2.5 billion doses of its Covid-19 vaccine by the end of the year. With each of these improvements, Pfizer says it has gone from producing 3 to 4 million doses of vaccine a week to 13 million doses a week. That will mean roughly 100 million doses a month and the ability to hit its goal of 300 million total doses delivered to the US government by July.
