I think there is a misconception here.
Vaccines do not stop the spread of Covid and this is typical of the governments woolly information.
You are at no more risk of catching Covid from an unvaccinated person than a triple jabbed person.
What you are at great risk of doing is dying should you contract it.
TBH I cannot think of any sane reason why you wouldn’t get jabbed. However the only person you are endangering is yourself.
I find that bonkers but if you have a death wish then so be it but the fact remains that the only person you are directly harming is yourself.
Indirectly you are destroying the ability of the NHS to treat sick people. That is a morally wrong thing to do in my book but what can we do, it’s a free country.
