Young people have as much chance of winning the lottery as of getting serious blood clots from the AstraZeneca vaccine
Last Wednesday, the European Medicines Agency stated there was a plausible link between the Oxford/AstraZeneca (Vaxzevria) vaccine and rare types of blood clotting, which the MHRA estimates may happen in one in 100,000 young adults who get the vaccine.
It is challenging to think of such low risks: when we have to count the zeros, all intuition goes. So what else has roughly a one in 100,000 chance for a young adult? We could choose from the risk of dying when under general anaesthesia, or in a skydiving jump, or, on the positive side, winning the Lotto jackpot if you bought 450 tickets, or guessing the last five digits of someone’s mobile phone number.
