Podaci iz Engleske, odnose se na omikron soj:
- Kada je u pitanju zaštita od simptomatske bolesti, zaštita nakon tri doze iznosi od 45-75%. Iliti, nije tačno da je potpuno isto da li je neko vakcinisan ili ne, jer vakcinisane osobe imaju makar 50 posto manje šansi da imaju simptomatsku bolest od nevakcinisane osobe.
- Kada je u pitanju zaštita od hospitalizacije, ona je naravno veća, i ide preko 85%:Two to 4weeks after a booster dose vaccine effectiveness ranged from around 65 to 75%, dropping to 55 to 65% at 5 to 9 weeks and 45 to 50% from 10+ weeks after the booster
protection against hospitalisation is much greater, in particular after a booster dose, where vaccine effectiveness against hospitalisation is around 85 to 90%
- Podaci iz Siren studije koja ocjenjuje zaštitu i reinfekcije kod zdr radnika: najmanja zaštita od omikron simptomatske i asimptomatske infekcije je kod osoba koje nisu bolovale prethodno i nisu vakcinisane. Najveća je kod onih koji su bolovali i primili 3 doze.

There is an additional incremental benefit from each vaccine exposure, even in those who have had prior infection (confirmed through antibody or detection through asymptomatic and symptomatic testing
