Dr. Katz is a former professor of medicine at Yale. Dr. Ioannidis, mentioned here before, is a professor of epidemiology and biomedical statistician at the Stanford University School of Medicine. Both were on Mark Levin's show tonight. If that destroys their credibility with you, that's your call.
Katz believes developing herd immunity is preferable to waiting some vague time in the future to develop a vaccine. Said mitigation and lockdowns are just delaying the inevitable. He proposed protecting the vulnerable and letting the rest get on with life. When herd immunity is developed to a certain degree, the vulnerable can begin to fully participate in society again. Did not advocate a program of testing and isolating.
Ioannidis said current information suggests an actual infection fatality rate of 1 out of...get ready for this...1,000. Same as seasonal flu. He said all the models were wrong, not because the effects of mitigation and lockdowns were figured incorrectly, but because the infection fatality rate was incorrectly believed to be far higher. He did not advocate for opening everything immediately, but said we should start on that process very soon.
