we must respond in a timely and careful manner

Austria

One woman (49) died 10 days after vaccination

Estonia, Latvia, Lithuania, Luxemburg have also stopped using the batch

EMA

Probably 3 cases and one death

One million doses in batch

Safety committee was reviewing the Austrian case

there is currently no indication that vaccination has caused these conditions, which are not listed as side effects with this vaccine

thromboembolic events in vaccinated people is no higher than that seen in the general population

22 cases of thromboembolic events, three million people vaccinated with AstraZeneca vaccine in the European Economic Area

Authorised 29th January

Epidemiology of venous thromboembolism

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4624298/

Incidence rate

Men, 130 per 100,000 per year

Women, 110 per 100,000 per year

That’s 10 per month per 100,000

That’s 120 per million per month

Therefore for 3 million of the population 360 thromboembolic events expected per month

Chance of reinfection, 25% to 60%

Brazil, natural laboratory, when coronavirus goes relatively unchecked

Breeding ground for new variants, several VOCs circulating

Rapid vaccination and NPIs required

Vaccines remains efficacious, but probably slight reductions
