Looking at the source, this was about King County, Washington, where more people over age 65 have completed the full vaccination series than there are census-estimated residents of that age. Effectively everyone over 65 has been fully vaccinated there. https://kingcounty.gov/depts/health/covid-19/data/vaccinatio...

If you tally up more age categories, about 92% of people over the age of 35 have been fully vaccinated.

Or flipped around, 80% of unvaccinated people in that county are under the age of 35, 15% are age 35–50, 5% are age 50–65, and essentially none are older than that.

It is amazing that even so, 83% of hospitalizations and 75% of deaths were among the unvaccinated. These vaccines are astonishingly effective!

In King County, for age group >65yo, vaccination rate is >95%, and the percent of vaccinated hospitalizations for this age group is 3%.

In UK, for age group >60yo, with similarly high vaccination rates, the percent of vaccinated hospitalizations for this age group is 82.5%.

These numbers inhabit different realities. I cannot think of any reasonable explanation. Some attempts:

* King County is failing to vaccinate the highest risk subpopulation within this age group.

* King County is hospitalizing comparatively vast numbers of unvaccinated elder covid patients.

* King County, UK, or both, is having serious data collection and/or reporting problems.

* UK is using a different vaccine

Edit. Peeking at the Singapore dashboards, they are much closer to the King County picture than the UK picture.

Yeah, I am not trying to say the vaccines are not extremely effective.
