This is something that countries need to decide and nobody seem to talk about but when they do release the vaccine dealing with people who are anti vaxxers or believe they don't need a shot to be safe. This is a huge concern because if they refuse shots they could potentially cause a third wave worse than what we have now, and that's a huge problem. We already are suffering really bad with high unemployment and people flaunting rules and getting sick, spreading virus even more. Countries need to get at least get 80%-95% of its population vaccinated to have a chance to irradiate Corona and stop it from spreading.
