For over two years now, the US government has been running its public vaccination campaign – the largest in American history – and has purchased all of the Covid vaccines administered in the States, including over 500 million doses from Pfizer.
The first 100 million vaccines cost circa $20 a dose ($19.50 as of July 2020), with the remaining doses purchased at around $30 per dose ($30.48 as of June 2022). This was due to an earlier agreement, wherein the US government invested $1.95 billion in vaccine production.
