Ok well good luck with that.
You said the vaccine does not prevent infection, that's not true. You said masks make no difference because it should have disappeared after you flattened the curve, that's not true, because you all went back to opening things up, people still go to parties, don't wear masks, which varies between states. In the UK there's been a direct correlation between lockdowns and social distancing and cases dropping, which is basic common sense because of the transmission. But there is this ongoing battle between the economy and health, so most of us here will choose the economy as we are not likely to die.
Why have you grouped Sweden and Japan and Korea together? Their responses are not in the least bit similar. The EU's response has been very disjointed and slow.
