Jimlur, You should know vaccinated people have less chance of getting seriously sick. Have less chance of being on a tube in ICU. Have less chance of transmitting the virus.
Also it is the common belief now that since protection from the virus decreases, a booster shot is recommended to keep immunity high.
No argument on those simple facts all should know.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
