During COVID’s omicron wave in U.S., death rates soared for older people

Despite strong levels of vaccination among older people, COVID killed them at vastly higher rates during this winter’s omicron wave than it did last year, preying on long delays since their last shots and the variant’s ability to skirt immune defenses.

This winter’s wave of deaths in older people belied the omicron variant’s relative mildness. Almost as many Americans 65 and older died in four months of the omicron surge as they did in six months of the delta wave, even though the delta variant, for any one person, tended to cause more severe illness.

While overall per capita COVID death rates have fallen, older people still account for an overwhelming share of them.

“This is not simply a pandemic of the unvaccinated,” said Andrew Stokes, an assistant professor in global health at Boston University who studies age patterns of COVID deaths. “There’s still exceptionally high risk among older adults, even those with primary vaccine series.”

COVID deaths, though always concentrated in older people, have in 2022 skewed toward older people more than they did at any point since vaccines became widely available.
