In this case he's right again. The odds of death for younger groups is pretty low. The odds of long covid or hospitalisation are also much lower for younger people, but add them together and it still has the potential to overwhelm hospitals and cause massive disruption through long Covid.
JTP can get individual facts right, throw enough **** at the wall and some will stick. What he can't seem to grasp is that even a 1% mortality rate is catastrophic for a highly transmissible disease or that death is not the only serious way that Covid-19 can affect someone.
