  1. False negatives don’t matter as much as you might think.

    “The simulated data here contrast policies that isolate people who test positive using four different assumptions about the quality of the test. Even a very bad test cuts the fraction of the population who are ultimately infected almost in half. And when I say bad, I mean bad – an 80% false negative rate, which means that 4 out of 5 of people who are truly infectious will get a negative test result – i.e. a result saying that they are not infectious.”

  2. An interview with Bob Nelsen. Worth reading!

    “I mean, I’m biased, but I think antibodies are probably the highest probability to work. I hope some mRNA works. I think if you ask scientists, they’re more skeptical. But I hope it works, especially in populations that tend to have weak immune systems. When you get skepticism about mRNA, it tends to be, ‘Yeah, it might work in a young person, but how is it going to work in the populations at risk?’ My own gut feeling is that mRNAt works a little and I hope it works a lot. And even then, there’s a role for all of the systems.If mRNA works, it bides us time to develop more potent, longer term vaccines. Antibodies will likely work and have the highest probability of working. There are multiple companies pursuing antibody therapy. So you hope that mRNA and antibiotic therapy start ramping up by the fall.”

    “We try not to meet at all with the other teams as much as possible. We’ll just say hi from across the corridor. Meals are the same. All our cafeterias and everything have got social distancing spaced in already,” said Chia, who is also a member of parliament and chairs a shadow committee on health.”
