“Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic,” said Tedros, the WHO Director-General. “It is scientifically and ethically problematic.”
this guy has been wrong about everything and said some bizarre things that put his credentials in question. right now, he's making a poor comparison.
have we had previous pandemics that only affect the elderly? diseases like the plague, ebola and even the worst examples of influenza attack the young and healthy; this one doesn't. so, we shouldn't be comparing this to historical pandemics like that, because the situation is unprecedented.
if it was ebola-gone-airborne, i'd agree with him. but, it's not - it's a novel cold virus that old people can't mount an immune response to.
