One for the medical people ... As more and more people take the jab I
was wondering if there are any stats that cover what sort of reaction
they may have to one and why that might be?

eg. We both had the AZ jab (she's had both now) and neither of us had
any reaction at all.

In contrast, a mate, his Mrs and their friend all had theirs and all
three suffered ranging reactions from headaches, overall aching to
nausea etc?

As I understand it, the vaccine (most vaccines) start building our own
antibodies by exposing them to an inactive version of the target virus
(profile?) in readiness for the real / active virus and it's likely that
it's that load on our bodies that causes some of these reactions?

So assuming it is (and not just an allergic reaction etc) if you don't
have any reaction symptoms at all, could it be you haven't been given
the vaccine (a placebo, I'm not suggesting this likely in this case),
that you already had sufficient antibodies for some reason (previous
similar viral infection or just because) so the body didn't react ...
your body doesn't actually react (create antibodies), effectively
meaning that you are no better protected or you just happen to have a
different physiology to those who do seem to have more prominent
symptoms, where the same things are going on re antibody generation but
your body can do it 'easily'?

There's always the chance that they actually caught Covid a short while
before having the jab and the 'reaction to the vaccine' was Covid symptoms.
