    💥🔥🧨 I am beyond excited to announce that I will be writing AN ABUNDANCE OF CAUTION, a book for , about the schools debacle in America during the pandemic. The book, in essence, will be a case study of how and why bad decisions are made THREAD 1/12

    A rare medical professional on TV emphasizing that Covid for healthy kids is akin to a cold or mild flu Also worth noting, the CDC estimates that up to half of infected kids will experience *zero* symptoms

    Glad to talk this AM on about Delta & how to best protect kids from this highly contagious variant. (Answer: surround kids w/ immune/vax'd adults, deploy rapid antigen (aka "contagiousness") tests, ventilate schools, etc.) 👇👇👇

    I spoke with the hospital Correction: -most of the Covid patients were *not* healthy people in their 20s and 30s

    Most of the Covid patients hospitalized at Jackson are healthy people in their 20s and 30s and ineligible for monoclonal antibody therapy. Some will require lung transplants, Dr. Lillian Abbo said.

    Wow Despite incessant claims of schools driving this wave, and Delta disproportionately affecting children scaring parents... Kids age 2 - 11y now lowest estimated prevalence of all ages<35, despite being totally unvaccinated, no masks anywhere and full time school for 4 months

    Takedown of CDC's (and by default, AAP's) total failure in school guidelines by 3 powerhouse doctors "follow the science" or "being safe" doesn't mean maximum NPI Screenshot quote is heartbreaking

    Or, I should have written, other scientist who can explain the reasoning behind the difference

    Have CDC or AAP explained why their recommendations for American children differ so dramatically from WHO, UK, and much of EU? If not, if any social scientists or psychologists have thoughts on their reasoning please DM me

    It's fascinating that a mathematician has been one of our leading and most resonant thinkers on the ethics of various public health policies during the pandemic. Some university should compile his tweets over the past year, turn them into a thesis, and give him a PhD in bioethics

    I am surprised that more people in public health are apparently not disturbed by the ethical implications of requiring young people who have confirmed prior COVID-19 infection to receive COVID-19 vaccines to be allowed to get a college education. 1/

    Comparing pediatric Covid v flu? It depends how the data is framed. CDC saying C19 is worse than flu in peds is just one frame. Timeframes, age, race, & factoring in that C19 vs flu hospitalizations are recorded differently, all yield different results, some with flu worse

    Thinking about next year, flu/covid both circulating...what can we do better? Big picture, then strata... MMWR Weekly hospitalization rates per 100k for children <18, flu and COVID. Flu has higher surges if looking at weekly rates, but COVID has been a consistent challenge.

    Glad to be quoted here⁩: “In my opinion, we should not have mask mandates in schools, given that kids are at exceedingly low risk of complications from Covid-19, and more importantly the science simply isn’t there to support a mandate.” 👇👇

    This seems surprising. If patient has peri/myocarditis from first dose of vaccine, after symptoms resolve go ahead and give a second dose?

    And the number of *males* 12-24 with symptoms within 7 days of vax is 415. (300 out of 20M is wrong calculation.) I.e. it's a larger numerator, and smaller denominator

    Updated ACIP slide presentation on VAERS data is confirming gross excess of post-C19 mRNA vax myopericarditis among those <30 yo, esp. 12-24 yo males. Remember: These are overwhelmingly HEALTHY young people!

    This seems to be misleading. 2.3% was based on universal screening. Symptomatic was 0.3%. It's not "young people," it's college athletes. Conversely, for vax, denominator is 15.4M age 12-24, not 20M. And divide by 2 for males is 7.7M. And 300 is only symptomatic in VAERS

    Will talk about myocarditis re: today's ACIP. Two numbers out there: 1. Myocarditis from COVID-19 vaccination of young people, CDC says 300 cases in 20 million people (1: 70,000: 0.0014%) 2. Myocarditis from SARS-2 CoV in young people 2.3%

    As some have noted, this doesn't appear to be new or revised text. It is the current recommendation, however, and here is a recent video echoing it; i.e. the recommendation is based on current data
