The Hepatitis B Shot America Calls Essential on Day One: Ontario Gives It in Grade 7

Ontario's routine hepatitis B program starts in grade 7, and Canada reported four acute cases in children under 15 in 2021. In the U.S., a court order keeps the universal shot in the first hours of life.

The FDA's 'Historic' Growing Heart Valve Has Been Stretched in Two Children

Children who get a new heart valve before age 2 can face up to five open-heart surgeries. Edwards' polymer valve is built to end that, and the trial behind its approval widened it in two of 62 kids.

Medical Chatbots Reached African Patients Before the Benchmark Meant to Grade Them

More than 500,000 people in Kenya texted an AI maternal-health line in 2024. The money to test tools like it arrived in 2026, and the global yardstick to grade them is still being built.

Drugs & FDA

After 56 Years of 'No Accepted Medical Use,' the FDA Wants Help Testing Ibogaine

Howard Lotsof said one dose ended his heroin withdrawal in 1962. The same alkaloid can stop a heart. The FDA has opened 45 days of comment on how to test it without killing anyone.

Infectious Disease

Actors Faked Bird Flu at 69 ERs and Clinics, and Triage Still Asked the 2016 Question

The actor's secret was a sick duck from Central Park, and only 7 of 73 triage desks asked about animals. Ten years after New York's first mystery-patient drills, the front door got slower.

A Cleanup Enzyme Fades as Fatty Liver Turns Dangerous, and Restoring It Cut the Damage in Mice

Cedars-Sinai researchers found liver cells lose an enzyme called UBE2N as fatty liver slides toward scarring, and restoring it reduced fat, inflammation and scarring in mice. It lands just as MASH has become a drug market.

Cancer

Merck and Moderna Say Their Melanoma Vaccine Worked, but Two Months On the Public Still Hasn't Seen by How Much

Merck and Moderna have announced only that their phase 3 met its endpoints. The smaller trial behind the excitement missed the conventional two-sided significance bar, and one bank has modeled a price as high as $475,000 per patient.

Brain & Aging

After 30 Hours Awake, a 20-Minute Bike Ride Saved About as Much Memory as a 90-Minute Nap

Sleepless volunteers who cycled for 20 minutes recognized nearly as many photos three days later as those given a 90-minute nap, even though the ride left their fatigue markers right where they were.

Drugs & FDA

Kennedy's Peptide Plan Reaches the White House, and Wall Street Is Already Counting the Money

Peptides already sell on a Queens bodega shelf, so moving them into licensed pharmacies is progress. Whether it protects anyone depends on one missing rule: test each lot and report every injury.

Brain & Aging

When the Shocks Stopped, People With Insomnia Got More Aroused, Not Less

In a third analysis of the same Boston volunteers, people with insomnia grew more aroused once the shocks stopped. The signal showed up only after engineers modeled the slow background sweat, and the next-day test missed significance.

Brain & Aging

In a Toronto Husky Study, Owners Moved First More Than Twice as Often as Their Dogs

Earlier sensor studies had the dog moving and the owner following. Among 22 synchronized Toronto owner-dog pairs, the human led in 10 and the dog in 4, and bedsharing showed no significant link to owners' measured sleep.

Investigations

In Pfizer's Pivotal Trial, a Volunteer's Pericarditis Became a 'Suspected COVID' Case That Counted Against No One

The only Argentine site in Pfizer's pivotal trial was run by the same doctor who authored the results, and when a 35-year-old developed pericarditis after his second dose, the records moved the episode off the vaccine's ledger.

Infectious Disease

Forty-Five Years After Acyclovir, the FDA's Herpes Headline Is a Warning Letter to Amazon

Some 520 million people carry the virus behind most genital herpes, and no drug clears it. The FDA's October move was a warning letter over herpes ointments and washes sold on Amazon.

Infectious Disease

A Siberian Plague Lab Lost a Scientist, and Moscow Is Asking for the Trust It Burned at Sverdlovsk

Daria Shipilova, 28, studied plague in Irkutsk until a severe pneumonia killed her, and about 200 people were quarantined. The biology says stay calm. The history says make Moscow show its work.

The FDA's Former Biologics Chief Says Public Health Can't See the Next Disaster Coming

Vinay Prasad ran the FDA's biologics center until this spring. His warning: the apparatus chases lettuce recalls and measles while a blood test for dozens of cancers heads toward Medicare with its central question unanswered.

Investigations

The MAHA Summit Charged Corporations Up to $300,000 for a Seat Beside the Officials Who Regulate Them

UnitedHealth got a panel. Grail, whose cancer test sat before the FDA, helped foot the bill. The regenerative ranchers and pesticide experts were nowhere on the program.

Investigations

The Fibroid Procedure That Spares the Uterus: Its Best Head-to-Head Evidence Was Paid For by the Device Maker

Radiofrequency ablation matched myomectomy on two-year symptom relief in a randomized trial. The device maker paid for that trial, and the durability question it cannot answer is the one that matters most.

Infectious Disease

Months After the FDA Recalled These Frozen Clams, No One Can Say Which Ecuadorian Waters Contaminated Them

Thirty-seven people across four states, thirty of them hospitalized, all linked to La Serranita black-shell clams imported frozen from Ecuador. The source waters are still under investigation.

Investigations

The Study Being Used to Close the Vaccine-Death Question Can't Rule Out Zero Excess Deaths in New Zealand

New Zealand's headline pandemic death study was co-authored by one of the country's most visible COVID modellers, and its four-year estimate runs from 1,134 fewer deaths than expected to 2,927 more. The modellers are calling it settled.

Drugs & FDA

Four Years After Congress Dropped the Animal-Testing Requirement for New Drugs, the FDA Finally Updated Its Rulebook to Match

The FDA's direct final rule swaps 'animal studies' for 'nonclinical studies' across its regulations. It eliminates no animal testing, moves no evidentiary bar, and sets up no program to prove the alternatives it now invites actually work.

Fifty injured Canadians testified in Ottawa over four days, and Health Canada did not show. The compensation program has spent more on its contractor's overhead than on the people it was built to pay.
