Researchers link 266K avertable deaths to COVID vaccination rates

The United States would have averted 266,700 deaths during the Delta and Omicron spikes of the COVID-19 pandemic if the excess all-cause mortality rate nationally matched that of the 10-most vaccinated states, a new study shows.

The data, compiled in a research letter from Brown University School of Public Health, and Penn’s Perelman School of Medicine, also showed that 122,304 deaths would have been averted if COVID-19 mortality rates matched those of the 10 most-vaccinated states between June 27, 2021 and March 26, 2022, the period covering outbreaks of the Delta (June 27, 2021-Dec. 25, 2021) and Omicron variants (December 26, 2021-March 26, 2022).

The rate of COVID mortality in the nation’s 10 least-vaccinated states – 145 per 100,000 population — was nearly double the COVID mortality rate of the 10 most-vaccinated states (74.5/100,000), according to the letter which was published Friday in JAMA Network.

“The U.S. continued to experience significantly higher COVID-19 and excess all-cause mortality compared with peer countries during 2021 and early 2022, a difference accounting for 150,000 to 470,000 deaths,” the letter states.

When compared with 20 other wealthy nations that had ready access to vaccines, the United States excess all-cause mortality – 145 deaths per 100,000 population – was the highest. However, the 10 most-vaccinated states had excess all-cause mortality (65/100,000) comparable with or lower than other wealthy countries, such as Germany (63/100,000), the Netherlands (63/100,000), and Italy (71/100,000) over the Delta and Omicron outbreaks.

Comparisons of direct COVID-19 mortality in the United States with the peer nations were even more stark, with 111 deaths per 100,000 population, more than double the rate of most wealthy nations. Austria (65/100,000) led all peer nations.

“This difference was muted in the 10 states with highest vaccination coverage; remaining gaps may be explained by greater vaccination uptake in peer countries, better vaccination targeting to older age groups, and differences in health and social infrastructure,” the letter said.
