      Those are, ironically, strawman arguments. We have called for and happily engaged with scientist in earnest public debate, but there are few takers. Details here:https://gbdeclaration.org/frequently-asked-questions/ …

      I’m grateful for the FAQs, but they did come later. They still avoid many key issues such as how many expected to die, be hospitalized & suffer long term health effects even *best case* in unshielded groups?https://www.demographicscience.ox.ac.uk/post/the-human-cost-of-natural-herd-immunity …

      How is 3-6 months feasible? Can’t have it both ways & say you’re not encouraging infection but want to reach natural immunity quickly. Such transmission even in young would overwhelm hospitals:https://www.pnas.org/content/117/41/25897 …

      What % of the population is in the vulnerable categories who are shielded? Between this & high transmission, how do you project this will bring about a rebounding economy?

      Vaccines are great for focused protection if we prioritize older high-risk people and their care takers, like Florida. To minimize deaths, we must also urgently improve protection of the old through standard public health measures listed in the @gbdeclaration & FAQ. 2/8pic.twitter.com/AXaGdmuBN5

      Nursing home residents have highest risk, but <1% of US population. People >60 who should work from home or take short sabbaticals are fewer than those currently working from home. There are many retirees, but protecting them with e.g. grocery deliveries is relatively easy. 3/8

      Not an economist, so I dare not make economic projections. The #GreatBarringtonDeclaration is solely based on minimizing mortality from #COVID19 and minimize lockdown generated collateral damage from eg cancer, cardiovascular disease and mental health. 4/8http://www.gbdeclaration.org

      Few people <50 require hospitalization. To avoid overburdened hospitals, the key is to protect the old through focused protection. Everyone should take basic precautions, and nobody should deliberately get infected. That is stupid. Also increases the herd immunity threshold. 5/8

      If the young live normal lives, some will be infected, but their risk is less than from lockdown collateral damage. Pandemic will then be naturally over in 3-6 months. Lockdowns just prolonged the pandemic while completely failing to protect the old. 6/8

          We do not know enough about #COVID19 to accurately predict expected number of deaths, hospitalizations, or long-term health effect, under any strategy. With unreliable R0, IFR and HI estimates, Imperial College type models are not helpful. 7/8

          We do know that there is more than a thousand-fold mortality risk between old and young. Zero-COVID is impossible in US/UK, and focused protection minimizes #COVID19 mortality irrespectively of R0, IFRs and herd immunity thresholds. 8/8https://www.linkedin.com/pulse/covid-19-counter-measures-should-age-specific-martin-kulldorff/ …

          The 3-6 month timeline relies on assumptions about the speed of transmission to reach population immunity. What are those assumptions? Also, claim that "risk is less than from lockdown collateral damage" requires assumptions & calculations w/ data which I have not seen.

          We are seeing very high LTCF infections and deaths after nine months, 50K cases/week, ~10K deaths/week, while applying a one-size fits all lockdown approach. One star care facilities are ~20% of all LTCF and 17 times greater risk than 3-5 star ones. No tone-it must be very hard.
