@ElenaP I do not understand your reticence to have Moderna when you have no experience of it’s side affects on
your body.
You are correct in saying that I have no experience of Moderna... For all I know, there may not be any side-effects. What is behind my preference for Pfizer is that three of my siblings had Pfizer vaccines (for both first and second jabs). They had sore arms and were a bit tired for a for a couple of days, but had no other side-effects. Therefore, I'm thinking that, having same genes, perhaps Pfizer may be kinder for my body. AstraZeneca is also a very good vaccine, and most people have no problems after receiving their jabs. However, I was really unwell for some time after my first vaccination (although less affected by the second jab).
Basically, I'm scared. I've been taken off one heart medication and waiting to have more investigation before they (hopefully a specialist?) decide what different medication to replace that with. Yet, I do not wish to delay the booster jab in case it offers protection.
From what I read from the various responses, the answer to my question is that I would not have a choice. So, this could be the case of crossing my fingers and hoping for the best.
