Good data maintained by OHSU (in a place with a very high vax rate).
~80% of Oregonians over 60 years old have been vaccinated and 65% of all people.
Based on that stat, as of 9/27, the data below show a ~20X reduction in likelihood of hospitalization among the vaccinated!

And when any effectiveness from the mRNA shots evaporates, then what ?

The protection provided by Covid-19 vaccines appears to wane over time, especially for people 65 and older, a US Centers for Disease Control and Prevention expert said Wednesday.
Ruth Link-Gelles, who helps lead the CDC's Vaccine Effectiveness Team, reviewed a series of studies looking at the overall effectiveness of vaccines in various groups between February and August and found similar patterns for Pfizer's and Moderna's vaccines, both made using mRNA.
The findings tended to support the argument that people's protection starts to wane after a few months, and that boosters might help restore their immunity.
Effectiveness started to wane a few months after people were fully vaccinated -- defined as two weeks after their second dose of either vaccine.
"For individuals 65 plus, we saw significant declines in VE (vaccine effectiveness) against infection during Delta for the mRNA products," Link-Gelles told the a meeting of CDC vaccine advisers.
"We also saw declines, particularly for Pfizer, for 65 up, that we're not seeing in younger populations. Finally there's evidence of waning VE against hospitalization in the Delta period," she said.
