Pfizer Inc. has secured a $3.2 billion agreement with the U.S. government to deliver 105 million doses of its COVID-19 vaccine, coinciding with ongoing vaccination efforts against new variants. Despite a recent share price increase of nearly 3%, the stock fell 0.7% amid broader market weaknesses and its pursuit of full U.S. approval for its antiviral treatment Paxlovid. The company anticipates approximately $32 billion in vaccine revenue for 2022, as it gears up to distribute vaccines targeting emerging variants.
