The profound health and economic impact of the Pfizer-BioNTech vaccine during its first year of rollout in the US is described in detail in a new study in the peer-reviewed Journal of Medical Economics.

It is estimated that in 2021 the vaccine, the most widely used against COVID-19 in the US, prevented 8.7 million symptomatic cases of the virus, as well as 690,000 hospitalizations and more than 110,000 deaths.
