Because the rest of the world has decided that COVID doesn’t exist any more, I am dropping down to one post per week. I am going to stop posting articles which are repetitive, especially ones of the form “Oh look! {Vaccines, boosters, treatments} still work against {Omicron, older variants}”; “Oh look! Vaccines wane in effectiveness!”;… Continue reading Week ending 2022-04-14 General

Mitigation Measures This article reports that, as advertised, the Government of Canada has dropped its requirement for a COVID test to enter the country for fully vaccinated travelers. Note that you do still need to fill out the ArriveCan app’s survey before you cross. Pathology Wow, this paper says that pregnancy increases your risk of… Continue reading 2022-03-31 and 2022-04-01 General

Vaccines This preprint took a very careful look at Pfizer, Moderna, J&J, and Novavax in test tubes. It measured a bunch of different components of the immune system in multiple ways. In general, the mRNAs waned the most and one shot J&J the least, but J&J started from a low enough place that even after… Continue reading 2022-03-29/30 General

Long COVID I have been seeing anecdotal reports for some time on Twitter that Paxlovid helped Long COVID, but nothing that seemed concrete enough to post here. Well, I can now point to this case study from a few weeks ago which says that Paxlovid completely got rid of Long COVID symptoms in one woman.… Continue reading 2022-03-26/27/28 General

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

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

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
