World AIDS Day is on Dec. 1.
Since 2004, global deaths have been in decline due to greater access to diagnostics, treatment & prevention.
This hard-won progress is now at risk due to major cuts to global public health.
We can't afford to go backward.

More data outlining how COVID vaccines reduce the risk of hospitalizations & death, especially among those aged 65 and older.
This aligns nicely with recommendations from Canada's National Advisory Committee on Immunization. 🇨🇦

Mutations in #H3N2 #flu viruses have some experts worried we're facing a second bad #influenza season. The new variant, subclade K, may be able to escape antibodies generated by previous infections or this year's flu shot. But some experts are hedging their bets. www.statnews.com/2025/11/20/f...
Is a bad flu season on the way? Experts see reason to be anxious
There are early indications that this flu season could be a bad one.

Update on the wild #polio discovery in Germany: The virus was found in wastewater in Hamburg. @rki.de, the German public health agency, says the virus sequence is very similar to some isolated in Afghanistan, so the likely source was an infected human. (page 10 here: www.rki.de/DE/Aktuelles...)

Someone in Germany is shedding poliovirus - a crippling disease which should be eradicated.
This is another stark reminder of the risks we face when global vaccination coverage slips.

Exciting to see a new compound showing promise against malaria.
As drug resistance grows, mosquito ranges expand & public health resources remain limited, the need for new treatments has never been greater.

Canada has lost its measles elimination status...a sad milestone.
Now is the time to double down on lowering barriers to routine childhood immunizations and ensuring Canadians have access to credible, science-based information.

Influenza cases are climbing in Canada.
Flu shots are widely available, and can help lower the chance of infection and hospitalization.
Below are this year’s flu trends (arrow) vs. the past three years.

@paulsaxmd.bsky.social knocks it out of the park with his analysis on 2 new COVID vaccine studies.
If you want data, nuance & common sense, have a read.
Key takeaway: COVID vaccine makes sense for those at greatest risk for severe infection (eg. elderly).

The southern hemisphere offers an imperfect but useful preview of our flu season, and they had a tough one: High case numbers & lower vaccine uptake among those most at risk.
Flu shots in Ontario for high risk folks are available now & to the general public starting next week.

A locally acquired case of Chikungunya virus in New York State? This is a first.
Chikungunya is a mosquito-transmitted infection that can cause impressive (and sometimes lasting) joint pain and inflammation.

New 🇨🇦 data in @cmaj.ca (from BC) showing relatively strong population-level measles immunity.
Outbreaks are likely to be more focal in under-vaccinated groups.
Some age cohorts are still <90% immune, so maintaining high vaccine coverage remains key.
