You don't really understand at all, do you you? The vaccine does help reduce the infections, but its main, most important effect is one of reducing symptoms and improving the outcome. Basically the number of people vaccinated is 80-90%, the number of unvaccinated being rushed into hospital occupying beds, in ICU and dying is 10 times the number of those vaccinated. Only the terminally stupid could fail to understand those figures. Number determined to have covid, no longer equals numbers in urgent need of attention, because the vaccination policy has worked well where people have accepted it. Most of those seriously ill and dying are the ones who have NOT been vaccinated. YOU AND THOSE LIKE YOU ARE THE PROBLEM and making it worse and more expensive, prolonged for everyone. The issue is that you completely fail to understand any of it.
Only the terminally stupid would fail to understand the pressure they are applying to the NHS by their stupidity. Only the terminally stupid would believe the dross on social media.
