Nobody below 50 should even think about taking the fucking thing. That age group is not at risk, and even then, the age group that is at risk is over the expected age limit. Which is the same as the flu. We don't lock down for the flu every winter. This science isn't that hard to understand, either. Old people's bodies just suck at what they used to do, so naturally minor sicknesses like the flu become battering rams on their bodies.
