> Among fully vaccinated people, there were about 27 coronavirus infections for every 100,000 county residents in June, according to figures presented Thursday. But among people not fully vaccinated, there were 125 infections for every 100,000 residents.
> That month, there were also 2 fully vaccinated people hospitalized for every 100,000 residents — much smaller than the comparable rate, 11, for people not fully vaccinated.
So per 100k fully vaccinated people, 27 cases and 2 hospitalizations. Or: 7.4% of cases resulting in hospitalization.
Per 100k not-fully-vaccinated: 125 cases and 11 hospitalizations. Or: 8.8% of cases resulting in hospitalization.
What this doesn't tell us is "how many cases were so mild and occurred in people who aren't getting test regularly that they went under the radar." I don't know of any data telling us anything about what the "mild case rate" looks like for vaccinated vs unvaccinated (it would be VERY hard to measure without widespread mandatory testing).
But if you've got a case that gets detected, the vaccine doesn't really seem to prevent that case from hospitalizing you at the same rate as before. It just prevents you from getting those cases nearly as frequently as the rest of the population.
Although I wonder if they will consider workers who passed covid before (and thus have antibodies) as "vaccinated".

Weren't there various (rare) occurrences of serious side effects? (such as the blood clot thing for astra and jonson or myocarditis for pfizer and moderna)
