Given that this pandemic has killed millions, shut down the world economy, and caused untold long term damage to children due to lack of stable schooling: yes, it’s because the precautionary principle is too costly.
Edit: sorry, my comment may have sounded snarky, which was not my intention. World-wide vaccinations do carry a risk. It’s just that such a risk clearly pales in comparison to the very known downsides of the current situation. I am in no way a vaccine expert and cannot comment intelligently on why long-term risks are considered to be low.
You mean million that died, had a positive PCR test at some time. There are still less people dying in 2020 than in 2018 in most countries even though population gets older and therefore more people are dying every year on average anyway.
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.
