I don't think you understand the science of it all chap, the vaccines reduce the chances of you getting it, they don't prevent transmission and they reduce the severity of the infection if you get it. So your two neighbors for example could be hospitalised etc if they hadn't been vaccinated.
Covid-19 has killed more people than the London blitz and we mobilised the country against that. America started a war after a couple of thousand were killed by terrorists, this has killed over 500,000 over there.
Again I don't think you appreciate what kind of reactions occur and I'm not sure you are able to judge the reactions reasonableness.
Maybe this is part of why.
The level of antigens you can have from a mild infection is considerably lower than those provided by just one vaccination, let alone two. Which you'd know, if you understood the 'science' you are referring to. You seem not to as you used a term like 'naturally protected', rather than something like 'an amount of immunity', or 'some antigens'.
