These data should not be interpreted as vaccines not working. In fact, these real-world analyses continue to reaffirm the incredible protection these vaccines afford, especially when up to date with boosters.

I found this interesting -

What’s more, about 1.1% of COVID-19 deaths occurred among Americans who were fully vaccinated and boosted in September 2021. By February 2022, that increased to about 25%.

Even so, in February, unvaccinated adults were 10 times more likely to die of COVID-19, compared to vaccinated adults, and five more times likely to require hospitalization, ABC News reported. Compared to fully vaccinated and boosted adults, unvaccinated people were about 20 times more likely to die of COVID-19 and seven times more likely to require hospitalization.

So it looks like it was either March or April 2022 when the CDC quit lumping in partially-vaccinated people into the unvaccinated totals.

The weekly death rate for unvaccinated people reached a high of 28.58 per 100,000 people on January 15, 2022 and has now steadily dropped since then. It's currently only .76 deaths per 100,000 people per week.

Note: Unvaccinated people have not received any dose. Partially-vaccinated people are excluded. Fully-vaccinated people have received all doses prescribed by the initial vaccination protocol. The mortality rate for the 'All ages' group is age-standardized to account for the different vaccination rates of older and younger people.
