Vaccination works. It may not always stop you CATCHING Covid, but it sure as hell bolsters your defences if you do catch it
I caught covid very early in the pandemic - before vaccines were avilable and before it was even realised as a pandemic. I had 3 MONTHS off work, have lost half my lung capacity, permanent hearing and eye damage and amd still dealing with other aftereffects nearly 2 years later
If you want to roll those dice, that's fine, but why should anyone pay your medical expenses when a vaccination is cheap insurance? And are you willing to pay the medical expenses of anyone you infect?
