@Dementedswan, I just read this on the Huff Post website:
"The risk of developing a blood clot with your second dose of the vaccine is even more rare. Up to 5 April, the MHRA had heard of 100 cases of blood clots with low platelet counts in the UK following vaccination with the AstraZeneca jab.
Of these, 99 reports were associated with the first dose of the vaccine and a single report followed a second dose, although this individual had medical conditions that could have caused the events. For context, this is out of 20.6 million first doses and one million second doses of the vaccine issued in total."
So, twenty times as many first doses have been given, but 99 times as many clots for first doses. Looks like if you got through the first dose OK, you should be fine with the second.
That's put my mind at rest somewhat!
