I had my first Astra Zeneca one in February, the second last month. I had two or three days feeling a bit cold and off colour, slight headache, after the first one…just a slightly more sore arm after the second but I’m fine. I’m 69, I have psoriasis which is an auto immune disorder and it hasn’t affected that or provoked anything else. I am part of a UCL study now, checking monthly to see whether I have antibodies …and I’m happy that I do have antibodies to the S (spike) but not the N (which I believe is Nucleus). This confirms to the research team that I have been vaccinated but that my blood shows no signs of prior infection with the actual virus. So it’s worth the monthly job of dripping blood from my finger into a tiny vial to know that! The study is funded till August this year and they may extend it to pick up indications of a dip in antibodies after several months and then whether the booster jabs in the autumn restore the antibody levels. I have several friends and family who have all been vaccinated and apart from some minor post vaccine side effects like sore arm, slight headache and tiredness etc we’ve all been fine and are glad to have been given our vaccines.
