You probably received the vaccine before variants emerged. At the time, the clinical studies of the manufacturers showed very high efficacy against the ancestral strain which was confirmed in real-world data.
When the mass vaccinations started alpha was already the dominant variant. When I was vaccinated it was clear that delta would matter most. So the vaccination for my age group was pretty pointless.
Also you didn’t cite a number of efficacy. Clicking through the many cases I come up with something less than 40% (protection against infection) within a year. If you compare that with the 97% for lifetime (measles) you can understand the disappointment of the people and why they don’t want to call it a vaccine.
The ancestral strain results were (naturally) also only of the kind: 95% protection for 3 months (or was the study period only 1 month?). Of course nobody could know for sure. But to many it was no surprise that the virus would escape any vaccine quickly just like the flu.
OTOH: From all data I saw, I agree that the vaccine improved the chances of survival of the elderly.
Obviously the variants make the situation much more complicated, that's why I cited the overview page of the CDC. Please don't cherry-pick the lowest figure you could find, this is highly misleading. Even for adolescents and Omicron, the studies find a very robust reduction in severe disease and hospitalization.
I’m not cherry picking the lowest number. You are shying away from giving a typical number. The 40% protection is actually much better then the anecdotal data I have. Two thirds of my vaccinated acquaintances fell sick with Covid19 in spite of vaccination.
If you’re honest the page for measles could be just as confusing as the covid19 page.
But CDC is confident to simplify it to a single number.
But let’s assume that the Covid19 vaccines provides a solid 70% protection during the first year. That’s still ten times more people vulnerable than after the measles vaccination! The disappointment is justified.
I thought meanwhile everyone agreed that the vaccines are very weak at providing sterile immunity?!
