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

Mitigation Measures Yep, they did it. On Wednesday I said that the government planned to drop the testing requirement to enter Canada. This article reports that it happened. This article says that as more restrictions are being lifted, a hospital in Montreal reports seeing an increase in “normal” child trauma: broken legs, scrapes, stomach flu,… Continue reading 2022-03-17/18 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

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

As I mentioned before, “everybody” seems to be acting like the pandemic is over. It’s not. Really it is not. I suspect people hear numbers like “60 per day in Canada” and think, “oh, well, 60 isn’t many people in a population of 39M”, but I think people just don’t understand just how rare death… Continue reading 2022-02-23 General

Vaccines This preprint says that if you are unvaccinated and get Omicron, that protects you against Omicron, but your protection against anything else is pretty crappy. If you get Omicron after getting vaccinated, you get really really good protection against all known variants. Treatments Two articles have come out in the past week which say… Continue reading 2022-02-12/13/14 General

Transmission Buried in this blog post was something I hadn’t ever known: the volume of air a person inhales/exhales per minute is around ten times larger during exercise than at rest. No wonder DrH closed the gyms. Treatments This article reports that the US FDA has approved a new monoclonal antibody — bebtelovimab — for… Continue reading 2022-02-11 General

Variants This is really strange. This article says that in New York City and also in some places in California, they have been seeing strange variants in their wastewater surveillance for the past year — variants they haven’t seen in any people. It wasn’t clear, but I think there are three main lineages (classed as… Continue reading 2022-02-03 General
