  1. Here’s another nice summary of how the mRNA vaccines work: https://www.cell.com/action/showPdf?pii=S0092-8674(20)31761-X

    We are hearing almost daily about the emergence of new variants, and concern about pressures that may lead to ‘escape’ from the current vaccines. Many of us are very familiar with the processes that lead to antibiotic resistance, but understand less about the factors driving adaptive mutations in viruses. Michael Mina posted a thread recently that said un-vaccinated people might drive this process more than partially (one-dose) vaccinated people. Would you guys consider doing an episode on the basic science of adaptive mutation in viruses? It sure is a prominent part of the recent news. Thanks for your great work and delightful shows.

  3. Dear TWIV crew: I want to join the many voices that have thanked your space for the answers to the avalanche of questions that, in my personal case, my rusty and precarious cardiac surgeon virology could not answer. All the ingenuity and thoughtfulness that each of you offers in your podcasts has been a reliable source of scientific information and also an opportunity to have fun and to make this past pandemic year more bearable. Believe me, things are far from satisfactory in this city at 8500ft high and with a population density of almost 17000 inhabitants per km2 (bronze medal for cities with more than 7 million) and a total of almost 9 million in the metro area with a barely decent health system. As I have been following your podcasts I have been encouraged to go back to basics: virology, epidemiology, biology, statistics, public health and other fields of knowledge trying to keep up with sound scientific evidence, which I notice is lacking all over the world.
    I recently read the press release for the SIREN study by PHE (1) from the UK and I got surprised with their “83% protection rate” from reinfection in previously PCR-positive health workers. In terms of science what does it mean? Are they using similar methodology for determining vaccine efficacy? The Statistical Analysis Plan in the pre-print (2) is beyond my comprehension. What is your take on that? Are we facing a similar situation like the so-called SARS-Cov2 variants transmissibility? In that regard, is this a well stablished phenomenon? I can tell differences between infectivity and transmissibility, but the latter implies so many variables aside from pure biological viral mutations and derived biological “behaviour”. I concur with those who think we need scientific evidence instead of broadcasting conjectures. Thank you and stay safe, we need to protect all basic scientists. Best regards from Bogotá, where temperature ranges from 45-75 F all year round but O2 partial pressure is 25% less than any of your places. Juan R Correa

    At 57:00 Rich asks about the motive for overcounting Covid-19 deaths: The answer is that there is a denier conspiracy theory that has the government paying providers more for Covid-19 care than for other care. Therefore, they claim everything a Covid-19 death to maximize profit. I personally know some of these people and they insist that this is true. Sad.
