A new Oxford Study compares the incidence of Cerebral Venous Thrombosis with the Astra-Zeneca vaccine, the Pfizer or Moderna mRNA vaccine and the risk if you get COVID19. The risk from the A-Z vaccine is 5 per million, the Pfizer and Moderna 4 per million and the risk if you catch COVID19 is 39 per million. The sample size is large with over half a million cases in each group, so the reliability of the research is quite good.While there is no COVID19 about, it is obviously safer to have no vaccine and no risk, but the COVID19 situation could change at any time. The Business Council and other non-medical political groups are calling for a more open society and for the case chasers to try to keep a certain level of infections once the gates are opened. i.e. We get the money- someone else fix the problems. Presumably they will try to stop further lockdowns, particularly as the percentage of the population who have been vaccinated increases.The bottom line is that the A-Z vaccine is almost as safe as the Pfizer one, and it is a good idea to be vaccinated ASAP in case the situation changes for the worse. I had the A-Z almost 2 weeks ago and only noted a slight headache, and tiredness on the evening of the vaccine, and a bit of local tenderness at the injection site the next day. I will have the second shot in 10 weeks.
