I had mine two weeks ago - I am over 60 too. Very little in the way of side effects - I did feel tired and a bit achey the next day but almost normal the day after. We have had only two cases of clotting in over 700,000 vaccinations, both people in their 40s (and no info on any other factors). Given the delays with Pfizer and Novovax still to get final approval, it seems sensible for older people to get the AstraZeneca and leave the Pfizer shots for younger people in the 1a category.
