It killed a million because it's novel. The flu also has killed millions, but because it's been around a while there's a lot of herd immunity to the flu. As time goes on, Covid's severity naturally decreases. Same as it has always been. And kids being kept out of schools despite being 99.999% immune is ridiculous.
Kids are being kept out of school so they don’t get the virus and spread it to somebody else. They aren’t immune, as far as I know. Just less likely to die from it.
