One dose of AZ?

[Bluenightowl]

For my own reasons I do not want to get a second dose of AZ (there is plenty of debate on other threads about AZ and I don't want this to turn into another anti EU/pro AZ thread ).

I read previously one dose of AZ will give 12 weeks protection against covid?

Can I then get a second dose of another vaccine e.g Pfizer or start again with a different one shot vaccine?

Or as AZ gives 76% protection for up to 90 days, and a second dose will increase protection up to 84% for an unknown time period - is it necessary to get another vaccine at all?

Yes, the bullying is very unhelpful to an obviously already anxious OP.
I have had a headache for a few weeks since my first AZ dose, and I am put off having a second dose.

My daughter worked with someone who had a brain aneurysm, had to have energency surgery and almost died. That was about 3 years ago and she was a perfectly healthy woman up till then. These things happen. I had the az jab and not worried at all.
