I’m posting here in the hope that someone has been in the same situation or is a doctor and can point me in the right direction 
My covid vaccine is booked for next week, quite excited about it, but I have a health condition that leaves me with a high heart rate and sometimes quite badly short of breath.
I talked to my gp about this, as I’ll likely have Astra Zeneca vaccine and there is the tiny tiny possibility of a blood clot. While I’m not too worried about this, one of the symptoms to look out for is shortness of breath. I raised this with my gp, as I wasn’t sure if I would recognise whether the shortness of breath was due to a potential blood clot, or just my usual shortness of breath. They weren’t very sure, but did advise that I should postpone the vaccine if I’m feeling ill/short of breath in the day. (I’m short of breath pretty much all the time so that’s confusing/frustrating as I actually want to be vaccinated!)
Is there any kind of vaccine advice line/place that could help with this? I’m between consultants for treatment at the moment as they’re passing me between consultants while they try to work out what’s actually wrong with me, so no one to ask for advice there.
Or a way to ask for a different type of vaccine? I’m 43 if that makes a difference.
Thanks for any advice!
