Vaccines are working in the UK. and they have mostly used AZ. After a threshold of the population was vaccinated , deaths are not rising even though the number of Delta cases has risen .
Vaccinations work. Anti vaxxers want you to die. Get vaccinated.
The wilful unvaccinated will die in what they have called in the USA the "Pandemic of the Unvaccinated".
I just wish that it was only the wilful unvaccinated and anti-vaxxers that got a dose of Covid, and that the results of their selfishness would be restricted to only them.
