The Weekly Dose, 30 Oct 2026

Weekly insulin, nasal Strep A jabs and tiny mushroom people.

Issue #1: the week in health, minus the hype.

🩺 The Weekly Dose

WHO wants TB treatment cut to four months and three or fewer jabs, with prevention in a single shot. Targets, not a product. No fridge required, which is ambition we like.
MHRA scientists made a needle-free Strep A vaccine, given up the nose or under the tongue, that worked in mice. 600 million-plus infections a year, no licensed vaccine. Mice first, people later.
The FDA approved once-weekly insulin icodec for type 2 diabetes from age 10. The children's evidence: an 18-patient dosing study plus modelling.
The UK approved icotrokinra, a once-daily IL-23 receptor-blocking pill for psoriasis, after four trials of about 2,500 people. A drug class that used to need a syringe now fits in a pill organiser.
At ESMO, sacituzumab tirumotecan cut the risk of death by 32% versus chemo in previously treated endometrial cancer (776 patients). Presented by Prof Domenica Lorusso: median survival 19.0 vs 12.1 months. No adjectives needed.
Rina-S cut the risk of death by 57% in platinum-resistant ovarian cancer in a 584-patient phase 3 trial. Company topline only. Applause pending full data.

Before birth, about 1 in 4 cortical neurons carry large DNA copy errors. By birth, most are gone (about 6%). Single-cell sequencing, 2,357 neurons, post-mortem human brains, Nature. Co-first author Dr Diane Shao. Write-up Why it's interesting: the brain runs quality control before go-live.
Autistic people reported more severe menopause symptoms than non-autistic people over five weeks. Survey, about 900 people (mostly women), Autism in Adulthood. Self-reported, so association only. Led by Eunhee Kim and Dr Rachel Moseley. Write-up Why it's interesting: menopause research mostly left this group out.
Volunteers were deliberately given a weakened dengue strain. Their past infections decided how well it replicated. Phase 1 human challenge, 45 adults, Science Translational Medicine. Led by Dr Camila Odio (NIH). Write-up Why it's interesting: it tests directly why a second dengue infection can be worse.

"Could lowering high blood pressure be as simple as stimulating your ear?" In the 63-person trial: overall, no better than sham. Larger trials needed.
