I confess I haven't had any jabs.
Is there a reason why?
It's obviously your choice to make, but they are proven to protect you. I'm not sold on needing a booster yet myself but I don't have that choice to make anyway for at least another few months. If I end up needing to, I'll go and get it. I'd definitely say get your first two. Having had COVID, like many in here I'm, sure, when I was partially vaccinated, I can tell you it's not nice, and neither are the potential long-term effects that I'm still getting over 4 months later (my second jab played a part in that, btw, but to me it was worth taking still). I can't know for sure if I'd have been worse without the vaccine or not, but I'm glad I had at least one dose when I got ill.
Think about yourself first and foremost without getting into the debate about it being a selfless act, because ultimately the vaccine is just about giving your body an extra wall of protection against this thing.
