People vaccinated with first doses, 16 or higher

N = 29,121,633

Oxford-AstraZeneca (ChAdOx1 nCoV-19)

N = 19,608,008

Pfizer-BioNTech (BNT162b2mRNA)

N = 9,513,625

People testing positive SARSCoV-2

N = 1,758,095

Within 4 weeks of three exposures

First dose from the ChAdOx1 nCoV-19 vaccine

First dose from the BNT162b2 mRNA vaccine

SARS-CoV-2 positive test

For each ten million people vaccinated using the AstraZeneca

An additional 107 could be hospitalised or die from thrombocytopenia

(one in 93,459)

9 occasions less than the danger following contamination

An additional 66 could be hospitalised or die from thrombus within the veins

Nearly 200 occasions less than the danger following contamination

For each ten million people vaccinated using the Pfizer

52 million doses to 12–29 years

1,226 reports of myocarditis after mRNA vaccination 42,414

One out of 42,414
