The COVID-19 vaccination in the United States saved nearly a quarter of a million lives in the first 6 months shots were available compared to a scenario where there were no vaccines, researchers estimate.
The researchers created a model that simulated two pandemic trajectories: one without vaccines and one with a vaccine program “reaching only half the daily vaccination rate of the actual rollout.”
“For each scenario, cumulative infections, hospitalizations and deaths were compared to the simulated trends under the U.S. vaccination program,” they explained.
According to the results, COVID-19 vaccines saved an estimated 240,797 lives (95% Crl, 200,665-281,230) and prevented an estimated 1,133,617 hospitalizations (95% Crl, 967,487-1,301,881) from December 12, 2020 to June 30. 2021. The number Preventing COVID-19 cases was estimated at more than 14 million.
According to the researchers, vaccinations have prevented a wave of COVID-19 cases, driven by the alpha variant, that would have occurred in April 2021 if not for vaccines. The wave had an estimated peak of 4,409 deaths (95% Crl, 2,865-6,312) and 17,979 hospitalizations (95% Crl, 13,191-23,219).
If vaccinations were administered at half the reported rate, the authors estimate that the US would still have suffered 77,283 deaths (95% Crl, 48,499-104,519) and 336,000 hospitalizations (95% Crl, 225,330-440,109).
“As New Variants of SARS-CoV-2” keep popping up, a renewed commitment to access to vaccines, especially among disadvantaged groups and in countries with low vaccination coverage, will be crucial to prevent preventable COVID-19 cases and end the pandemic,” the authors wrote.
