This isn't a fair comparison. There weren't flu vaccines for the Spanish Flu, were there? I'm pretty sure if there were, and 95% of the population had their vaccinations, that this wouldn't have happened when they "insisted on getting back to normal" huh? Also the most deadly mutation of the Spanish flu happened only months after it first was discovered in 1918. By 1920 it had mutated into the much less deadly endemic flu we still know today. We are at that stage of COVID. Over 2 years after the Spanish Flu began, it had become much weaker to the point it was no more deadly than common versions of the flu we know today. Over 2 years after COVID began, it's a pretty damn similar situation.
Don't mislead readers by implying that this is comparable to the Spanish flu during 1918.
