Vaccines
Moderna has registered to do a small Ph2/3 trials on children.
A preprint says that the first vax dose for cancer patients is not very effective, but that the second dose gives them good protection.
Zeynep Tufekci has an essay arguing that the language of “we should vaccinate them over there so they don’t make mutant COVID which will kill us” is not only immoral but counter-productive.
VOCs
Yet another study says that B.1.1.7 is more lethal, this time saying 55% higher. This Twitter thread by the author is a nice dive into the nitty-gritty of the study.
Schools
There’s an accepted prepring which says that three-foot physical distancing is as good as a six-foot physical distancing in schools. @DiseaseEcology, who I have seen give really good analyses, absolutely shreds the paper, however.
