Mitigation Measures This article says that the federal government is going to drop the COVID-19 test for travellers entering Canada, for both land and air crossings, for fully vaxxed travellers. Rumour has it that the requirement will be dropped on 1 April. Vaccines Remember J&J? The lame-ass one-shot vax that nobody wants? This article says… Continue reading 2022-03-15/16 General

Long COVID This preprint says that people with Type O blood are 4.2x as likely to get Long COVID as non-O people. From this Twitter thread: Treatments This preprint looked at effectiveness of monoclonal antibodies against BA.1 and BA.2. It is striking to me how well a monoclonal antibody works against one of the strains… Continue reading 2022-03-12/13/14 General

Pathology Yesterday, I posted this preprint which talked about how pre- and post-COVID brain scans showed changes in the brain. Yesterday I saw a Twitter thread talking about that study. The author said that a loss of brain matter is normal when you lose your sense of smell, due to the circuits not being exercised.… Continue reading 2022-03-08 General

Pathology This preprint from the UK which compared brain scans made during the Alpha wave to brain scans in the same people several years prior. They found that people who had had COVID infections had more degradation in their brains (on average) than those who had not. They excluded people who had been hospitalized from… Continue reading 2022-03-05/06/07

Long COVID As a reminder that Long COVID is a real problem, this report says that 2.4% of people in the UK report Long COVID symptoms more than four weeks after infection. Not 2.4% of the people who got Long COVID, 2.4% of ALL the people. Of that 2.4%, 45% (i.e. 1.08% of the total… Continue reading 2022-03-04 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

Pathology This article reports that a team can predict with 83% accuracy the severity of COVID-19 by looking at three components of blood (mostly TH17, a helper T cell, and immune system cells IL-17 and IFNG). Vaccines Yesterday I referenced a preprint which said that vaccine effectiveness in kidlets was awful. Today, there’s a different… Continue reading 2022-03-01 General

Pathology This article suggests that the reason that COVID-19 hits old people so much harder than young people is that old people have more antibodies to important pieces of their own innate immune system, particularly interferons. (In other words, they attack critical pieces of their own immune system.) They found that the proportion of people… Continue reading 2022-02-25 General

Long COVID This preprint and this lay article report on a big US study of mental health effects after COVID-19 which found that people who had had COVID-19 had (compared to controls): 1.35x risk of anxiety disorders; 1.39x risk of depressive disorders; 1.38x risk of stress and adjustment disorders; 1.55x risk of antidepressant use; 1.65x… Continue reading 2022-02-16 General
