One caveat is death trends tend to lag case trends by about three weeks. In coming weeks, deaths among the vaccinated will almost certainly rise, given how sharply cases have risen. These deaths will likely be concentrated among people in vulnerable health, including the elderly and those with a serious underlying medical condition like a previous organ transplant — especially if they’re not boosted.
This likelihood — along with the problem of overwhelmed hospitals — is one of the strongest arguments for taking steps to reduce the size of the current Omicron wave. More vaccine mandates and indoor mask wearing can help reduce cases and, by extension, deaths, experts say.
But the early data raises the possibility that the increase in deaths among the vaccinated will remain relatively modest. The gap in the mortality charts above can’t merely be a reflection of the lag between the cases and deaths. After all, deaths among unvaccinated New Yorkers and Seattleites had already begun to surge in December. Deaths among the vaccinated had not.
(In Boston and Chicago, Covid deaths have also risen, these charts show.)
The bottom line
Vaccination remains highly effective at preventing severe Covid illnesses. And Omicron is milder than earlier versions of the virus. The combination means that most Americans — including children and vaccinated adults — face little personal risk from Omicron.
The risk is not zero, to be clear, even among people who are generally healthy. But it is very small. Every day, people live with small risks, be they from the seasonal flu and other illnesses or from riding in a vehicle, playing sports or other activities.
For the unvaccinated, the situation is very different. Omicron is still severe enough that it will lead to debilitating illness and death for many unvaccinated people. In much of the U.S., a large number of adults — including older adults — remain unvaccinated:
