Mitigation Measures This paper reports on a big study in the US which compared school districts which had mask mandates with those that did not. For every 100 community-acquired cases, districts with universal mask mandates had 7.3 infections, while districts with optionally masks had 26.4. Don’t let anybody tell you that masks don’t work Testing… Continue reading 2022-03-10 General

Vaccines You might be wondering what the holdup is with shots for toddlers and babies. After all, the Pfizer shots were effective (during the Delta regime) for the under-two babies, just not for the toddlers (presumably because the dose:weight ratio was high enough for the babies but not the toddlers). This article about the approval… Continue reading 2022-03-03 General

Pathology This preprint says that they used immuno–positron emission tomography to see SARS-CoV-2 infection in cells, and found it kind of all over the male genital tract of macaques. Here’s a lay article on the subject, which added that 10-20% of men who get COVID-19 have problems with their genitals. Men, don’t get COVID-19, it’s… Continue reading 2022-03-02 General

Transmission This preprint looked at COVID-19 in some white-tailed deer killed by hunters in Ontario. It found COVID-19 in ~6% of the deer, and the whole-genome sequencing found that the viruses have mutated a lot. (“Highly divergent” was the language in the preprint.) Furthermore, they found one human from the same geographic area with known… Continue reading 2022-02-26/27/28 General

Vaccines This article reports that Health Canada approved Medicago’s Covifenz, a plant-derived protein subunit vaccine. In trials, Covifenz had 71% effectiveness against Delta infection, and 100% effective against hospitalization. According to their product monograph, it is fridge-stable, but needs to be handled gently. Medicago’s vax is a virus-like particle, what I generally call a “spikey… Continue reading 2022-02-24 General
