FRANKFURT - BioNTech said on Monday that it and partner Pfizer had signed agreements to deliver 1.8 billion doses of its COVID1-9 vaccine this year, up from 1.4 billion announced in March.

In a statement on first-quarter results, it also reiterated that output capacity for the vaccine would reach 3 billion doses by the end of 2021, and more than 3 billion doses in 2022.

Pfizer last week said the pair was targeting production of as much as 4 billion doses of the shot next year, mostly for low- and middle-income countries.
