We're trying to balance multiple factors: living our life normally, protecting ourselves, protecting family members we still interact with. We take some known risks: sending child to preschool, while taking known precautions: wearing masks, getting vaccinated. If being vaccinated reduces the chance that we might spread the virus to someone, then that's a marginal advantage we'll stack in our favor.
Living normally is probably only one thing that we can do. Vaccines, masks, lockdowns... None works. But if we are daily exposed to news with fear agenda, we will never live normally again. We shoul live, not survive and loose our time.
Btw... Reduced chance of spreading virus wont make people immune to catch it. But yet... Gonverments consider vaccinated people as immune. Why?
