Let's look at reality:
Vaccinated:
Can still transmit COVID19, although at a much lower rate.
Due to being vaccinated, the symptoms are much lower, if they get COVID19, and that reduces the chance of going to the hospital and occupy nurses and doctor's time, cost the tax payers money and take away beds from sick people who have no control over being sick.
Unvaccinated:
Can transmit COVID19 at a higher rate than those who are vaccinated
Will occupy hospitals 90% more than vaccinated people
Will cost taxpayers money
Will unnecessarily take away beds and services for those who need to be treated
Will put doctors and nurses under stress
