Effectiveness - if it's quoted at 95%, see below, from the USA, on the 5%
CDC report that 10,262 fully vaccinated residents of the USA experienced breakthrough* COVID-19 by 30 Apr (and think it likely the figure is under-reported). Within these, 27%, were asymptomatic and 2% (160 people) died.
995 people were hospitalized (12%), including 289 hospitalized for asymptomatic infection or for reasons unrelated to COVID-19,
Study was published online May 25 in Morbidity and Mortality Weekly Report (MMWR).
By end April USA had fully (ie double dose) vaccinated 101M. 5% of 101M is . .
* tested positive for COVID-19 more than two weeks after being fully vaccinated.
Using those figures, and an in-my head approximate calculation, it would seem that - over what, two/three months?- ~ 0.01% (probably more, as I assume asymptomatic infections are more likely to have been missed/gone unreported) of the fully vaccinated experienced breakthrough infection(either symptomatic or asymptomatic), significantly fewer than 0.01% were hospitalised with C-19 and about 0.00016% of the vaccinated population actually died of C-19. We have no information on the ages and presence of co-morbidities in those for whom vaccination failed to provide full immunity, but nevertheless this is clearly an astonishingly-successful vaccine.
