You misunderstood what I was saying. I'm not talking about 1918. Covid vaccines are being pushed to tamp down breakthrough variants. There is also as much risk of a deadly breakthrough variant of the flu right now. My point of bringing up 1918 is to show that deadly flu breakthrough variants are possible. Considering that this is still the case in 2021, should we mandate flu vaccines as well, right now? If not, the argument for mandating covid vaccines is inconsistent.
