AstraZeneca doubled the incidence of cerebral vein thrombosis - proven Two independent groups of British scientists found that vaccination against coronavirus with AstraZeneca increased the incidence of cerebral vein thrombosis by about two times compared to pre-vaccination values. The researchers estimate that vaccination causes 1-3 excess cases per million people. Both the first and second papers were published in PLOS Medicine. A few months after the AstraZeneca coronavirus vaccine began to be used in Europe, it showed side effects. One of them was thrombosis, which rarely, but still affected young women. In April 2021, the European regulator listed thrombosis as a rare side effect of AstraZeneca after the discovery of this adverse reaction. - Research 1 https://bit.ly/3hbM9og Association of COVID-19 vaccines ChAdOx1 and BNT162b2 with major venous, arterial, or thrombocytopenic events: A population-based cohort study of 46 million adults in England - Research 2 https://bit.ly/3paXNUS First dose ChAdOx1 and BNT162b2 COVID-19 vaccinations and cerebral venous sinus thrombosis: A pooled self-controlled case series study of 11.6 million individuals in England, Scotland, and Wales
