It has been estimated that, thanks to the availability of Covid-19 vaccines in the U.S., from November 2020 until March 2022, 2,265,222 deaths were averted, 17,003,960 fewer hospitalizations occurred, and 66,159,093 Covid-19 infections were avoided – all leading to $899.4 BILLION in healthcare costs averted.

These are huge numbers!!! I am one of those 66 million.
