Some weeks, there’s not much news; some weeks there’s a lot. This week had a lot and was a lot for me to process. Vaccines πŸ’‰ CORRECTION! I re-read the PHAC recommendations for who should/may get a second vaccination this year, and I believe that what I said on 2025-08-11 was (probably) wrong. I said… Continue reading 2025-08-25 General

(Addendum 2025-08-15: I actually published this on 2025-08-11, not on 2025-08-13, but it’s too late now to change the URL. Oops, sorry.) COVID-19 Vaccines πŸ’‰I might need to fly across the continent to support a relative who is going to get major surgery, so I tried to schedule a vax appointment in the US. No… Continue reading 2025-08-11 oops 13 General

COVID-19 Vaccines β€ΌοΈπŸŽ‰πŸπŸ¦· Scientists have found an alternative method of giving mucousal vaccines: with dental floss! This paper (2025-07-22) found that flossing mice three times with floss covered with influenza virus, at two-week intervals, protected the mice from a lethal dose of influenza. All the mice who had been flossed survived, while all the unflossed… Continue reading 2025-08-03 General

COVID-19 Long COVID β€ΌοΈβ€ΌοΈβ€ΌοΈπŸŽ‰πŸŽ‰πŸŽ‰This article (2025-07-22) and this paper from Canada (2025-07-07) say that scientists have found a really easy blood test to diagnose ME/CFS! (They look for the protein SMPDL3B.) This is both great for testing purposes but also suggests a treatment! They haven’t looked for SMPDL3B in Long COVID patients yet, but I… Continue reading 2025-07-26 General

Wastewater levels are all going down. Was that tiny little our summer wave? Did we already peak????

People whose first infection was pre-Omicron had about half the chance of getting more than three persistent symptoms after their second infection than after their first. However, people who… Continue reading 2025-07-04 General

🌊 This article from Singapore (2025-06-14) says that their wave is now peaking, about five or six weeks after their wave started in late April. That feels a bit fast to me — we usually see two months from the start to the peak here. I’m also a bit surprised that COVID-19 growth here has… Continue reading 2025-06-20 General

COVID-19 Variants 🦠🧬 NB.1.8.1 is still causing a lot of cases in Asia and Australia.

COVID-19 Variants Other people are starting to notice all the cases in Asia. This article from USA (2025-05-23) says that CDC has discovered a bunch of cases of NB.1.8.1 — the variant which is causing havoc in Asia — in wastewater arriving in planes from abroad. I know, I know, the US is not Canada,… Continue reading 2025-05-24 General
