According to the latest figures from the European Medicines Agency database Covid-19 Adverse reactions to the vaccine, 162,610 adverse events and 3,964 deaths, have now been reported. Of the three major vaccines approved and deployed in Europe, the Pfizer-Biontech vaccine accounts for more than two-thirds of the reported infections and deaths, or 102,100 and 2,540 events, respectively. Oddly enough, women disproportionately make up 77% of adverse events. This greater than 1: 4 ratio between the sexes is also observed in the Moderna and AstraZeneca vaccines. So far, there appears to be no scientific explanation for this gender disparity.
