Oxford's shot
with India's Serum Institute
Moderna's shot
a US company
Experts advising the World Health Organization (WHO) want 2 new vaccines added to an Ebola trial in Congo.
The outbreak has killed more than 5,300 people, most of them in Congo.
This will be the first time vaccines made for this virus are tested during an outbreak of it.
Africa's disease agency counts 10,444 confirmed cases.
Who is involved
World Health Organization (WHO)
the UN's health agency; its expert groups recommended adding both vaccines
Who is involved
Tedros Adhanom Ghebreyesus
WHO's chief; he says vaccines cannot replace early care and contact tracing
Why it matters
WHO's chief, Tedros Adhanom Ghebreyesus, says vaccines cannot replace early care, contact tracing, isolation and safe burials.
Why it matters
He also asked countries such as the US and Ghana to lift travel limits.
How it works
Epidemiologists, who study how disease spreads, call Tumaini's design ring vaccination: it enrols the contacts of each confirmed patient.
How it works
4 of 4
rings in place so far
Tumaini has 4 rings so far, including contacts of people who fell ill or died.
How it works
It tests several vaccines inside one trial, which is how Oxford's and Moderna's shots can join it.
Seen it before
A firefighter wets the houses next to a fire, not every house in town.
The truth
So far, tests in people have measured safety and immune response, not protection from Ebola.
The truth
Oxford's and Moderna's Covid vaccines were linked to rare blood clots and heart inflammation.
What comes next
WHO expects results from the vaccine trial in early 2027.
What's really going on
WHO's advisers have chosen 2 vaccines built for Bundibugyo, but more than 5,300 people have died and the trial's results are not due until early 2027.
What's really going on
Elsewhere, the work of finding and selling medicines moved between companies: Boehringer and AbbVie bought early drugs, Ultragenyx cut its own research, and CVS is splitting its shops from its insurer.
Who pays
Health workers in Congo
They work in a conflict zone without a proven vaccine, and a nurse was killed responding to an alert.
Who pays
People travelling from Congo
Travel limits by countries such as the US and Ghana fall on them, against WHO's advice.
Nobody knows yet
Whether either new vaccine protects people from Bundibugyo.
Tests in people so far have measured safety and immune response, and WHO expects trial results only in early 2027.
Nobody knows yet
How many people have died in Congo.
Africa's disease agency counted 5,372 deaths in Congo on Monday, while Congo's own data to 31 October shows 5,103. Neither report explains the gap.
Nobody knows yet
How deadly this outbreak really is.
The BBC reported a death rate of 48.6% at the end of October, while Euronews and Africanews say more than 50%.
Nobody knows yet
When Congo will approve the 2 new vaccines.
WHO says they join the trial after national approvals and names no date.
Good news
Two vaccines built for the Bundibugyo kind of Ebola will be tested during an outbreak of it for the first time, and WHO's advisers were unanimous in backing them.

A British health worker with Ebola flies home
Swipe up for the story ↑Scroll down for the story ↓
A British health worker with Ebola is being flown from Congo to Britain, a document seen by Reuters shows.
“the risk to the UK public from Ebola remains low”
The UK government confirmed that a British citizen in Congo has tested positive.
Who is involved
A humanitarian group had sent the person to help fight the outbreak.
A specialist ambulance will take the patient to a unit for high-risk infections.
How it got here
It is the first British case in this outbreak.
How it got here

Switzerland flies a patient out of Nigeria
Switzerland flew out a patient from Nigeria last month, and France reported a case in June.
Why it matters
The people sent to help are among those catching it.
How it works
Epidemiologists call this contact tracing: people with Ebola infect others only once they have symptoms, so contacts can be found.
How it works
Ebola passes through body fluids, with no evidence of spreading by coughing.

CVS will split into two companies
Swipe up for the story ↑Scroll down for the story ↓
CVS Health, a US health giant, said on Wednesday it will split into two companies.
Who is involved
One company keeps the name CVS Health, with its insurer Aetna and its drug middleman, Caremark.
Who is involved
Caremark is a pharmacy benefit manager, or PBM: a middleman on drug prices between drugmakers and health plans.
How it got here
2007
buys Caremark
2018
buys Aetna for $78 billion
2028
splits in two
CVS bought Caremark in 2007 and Aetna in 2018, the second in a $78 billion merger.
It made a $2.2 billion profit last quarter, after a $4 billion loss a year earlier.
Why it matters
Arkansas
Tennessee
Arkansas and Tennessee have laws that would stop one owner holding both pharmacies and PBMs, and CVS is challenging them.
Why it matters
CVS Pharmacy will have to stand alone in a trade where some chains have gone private or bankrupt.
How it works
Economists call owning several steps of a chain vertical integration, and CVS built it by buying Caremark and Aetna.
How it works
CVS's chief says what the shops and the insurer share can be kept through contracts.
Seen it before
A cafe that sells off its bakery can still buy the same bread from it each morning.
The truth
CVS's chief
not regulators
Leerink analyst
maybe regulators
CVS's chief says regulators are not the reason for the split.
How it works
Why a company does some jobs itself and buys the rest
How it works
Economists call it the make-or-buy choice: a firm does a job itself only while that costs less than paying someone outside.
How it works · step 1 of 5
Ronald Coase, an economist, asked in 1937 why companies exist, when every job could be bought from outside
How it works · step 2 of 5
Buying has costs: finding a seller, agreeing a price, checking the work
How it works · step 3 of 5
Doing it inside has costs too: bosses, staff and work that may fail
How it works · step 4 of 5
The company picks whichever costs less for that one job
How it works · step 5 of 5
When those costs change, the line moves: firms buy in, or split up
The twist
A company is a line drawn around the jobs that cost less to do inside than to buy. Today that line moved at CVS, Boehringer, AbbVie and Ultragenyx.
The picture
Each way of getting a job done has its own bill. A company compares the two, one job at a time.
Seen the same day
CVS's chief says what the shops and the insurer share can be kept by contract, so the company no longer needs to own both.
Seen the same day
Boehringer pays Sino to run the early work on 6 projects, then decides which to license, instead of doing that work itself.
Seen the same day
Nxera's chief called IBD too complex and expensive to develop, so the work moved to a firm that already sells IBD drugs.
Seen the same day
Ultragenyx is halving its research spending and will fill its pipeline partly with small deals, moving some of the job outside.
The catch
Real firms rarely do these sums cleanly: they misjudge their own costs, and laws can move the line as much as prices do, as Arkansas and Tennessee are trying to do with CVS.
The whole
A person collecting a prescription sees one shop and one pill.
The whole
Behind them sit a lab in China, a drugmaker in Germany, a middleman and an insurer, each doing the part it finds cheapest, and none of them can see the whole chain from where it sits.
Who pays
CVS Pharmacy, the new shop company
It loses a parent with an insurer behind it, in a trade where other chains went bankrupt.

The Wegovy pill lifts Novo's forecast
Swipe up for the story ↑Scroll down for the story ↓
Novo Nordisk, the Danish maker of the weight-loss drug Wegovy, raised its yearly forecast on Wednesday.
In May, the best case the company gave was a 4% drop.
Its Wegovy pill, on sale since January, brought in 5.39 billion Danish kroner, about $811 million, last quarter.
Foundayo, the rival pill from Eli Lilly, reached $184 million, which was $44 million short of estimates.
How it got here
Novo has lost about two-thirds of its value since June 2024.
Who is involved
Finance chief Karsten Munk Knudsen is leaving, and Luigi La Corte of Galderma, a skin-care drug company, will replace him.
Why it matters
63 of 100
of the US market, Lilly claims
Patents on Wegovy's main ingredient end several years before those on Lilly's rival drugs.
How it works

Business schools call this a first-mover advantage: Novo's January pill is outselling Lilly's April pill so far.

Boehringer pays for six early cancer projects
Swipe up for the story ↑Scroll down for the story ↓
Boehringer Ingelheim, a German drugmaker, agreed on Wednesday to $358 million in early payments to China's Sino Biopharmaceutical.
6 of 6
cancer projects, none yet in people
The money covers 6 cancer projects, all still at the preclinical stage, before any human trial.
Sino could earn up to $7 billion more if the drugs keep advancing, plus a share of any sales.
Sino runs the early work up to agreed points.
2 of 6
projects with worldwide rights on offer
Boehringer could buy worldwide rights to 2 of the drugs and rights outside China to the other 4.
Who is involved
LaNova Medicines
5 projects
Beijing Tide
1 project
Sino's LaNova Medicines unit made 5 of the projects, and its Beijing Tide Pharmaceutical unit made 1.
Why it matters
US lawmakers may look harder at the surge in drug deals with China, BioPharma Dive reports.
How it works
Lawyers call this an option: Boehringer pays now for the right to license each drug later.
How it works
Boehringer keeps that choice until the early tests report, so it pays licence fees only for drugs it picks.
Seen it before
A small deposit holds a flat while you decide, and walking away costs only the deposit.
How it works
Boehringer pays Sino to run the early work on 6 projects, then decides which to license, instead of doing that work itself.
The idea, in story 3: Why a company does some jobs itself and buys the rest →Who gains
Boehringer Ingelheim
It can wait for Sino's early tests before paying licence fees, so projects it does not pick cost it no fee.
Who gains
Sino Biopharmaceutical
It takes in money now while keeping the running of early work, and keeps China rights on 4 of the 6 projects.

Gene repair shows early results in sickle cell
Swipe up for the story ↑Scroll down for the story ↓
Kamau Therapeutics, a California biotech, released its first results from repairing the gene fault behind sickle cell disease.
Who is involved
In sickle cell disease, a faulty gene makes bad haemoglobin, the blood protein that delivers oxygen.
Doctors repaired the fault in 3 patients' own stem cells outside the body, then gave the cells back.
3 of 3
patients with no pain crises since
All 3 no longer need blood transfusions and have had no pain crises since, Kamau reports.
After 12 and 8 months, sickle haemoglobin in the 2 longest-followed patients was 17.6% and 19.1%, both below 20%.
How it got here
Late 2022
Graphite Bio halts its trial
Now
Kamau reports 3 patients
The treatment, nula-cel, began at Graphite Bio, which halted its trial in late 2022 and later disbanded.
Why it matters
Few people with the disease have had the approved gene treatments so far, Kamau's co-founder says.
How it works
Geneticists call this homology-directed repair: the cell swaps its faulty DNA for a healthy copy, as nula-cel does.
How it works
Casgevy, already approved, works differently: it switches on baby haemoglobin instead of replacing the fault.
Seen it before
Correcting a typo in the master copy beats sticking a note beside it.
The truth
3 of 15
of about 15 planned patients reported
This is an early-stage trial with 3 patients so far, of some 15 planned.
Good news
No serious side effects were tied to the repaired cells themselves.
What comes next
The results will be presented on 14 December in New Orleans, at a meeting of blood specialists called ASH.
Nobody knows yet
Whether repairing the sickle cell gene beats Casgevy, the approved treatment.
Kamau's co-founder believes it may. The journal GEN calls that a major question, and only 3 patients are reported.
Good news
Three sickle cell patients who had the gene fault repaired in their own stem cells no longer need blood transfusions and have had no pain crises since.

Democrats won both chambers of the US Congress on Tuesday, which changes who can question US health officials.
“Subpoenas”
Ron Wyden, a Democratic senator who leads on health, posted one word that night: "Subpoenas".
Who is involved
Annie Andrews, a children's doctor, won a South Carolina seat in the US Senate.
Roger Marshall, a Kansas senator who helped found the Make America Healthy Again caucus, lost his seat.
Why it matters
Analysts expect closer questions for US health secretary Robert Kennedy Jr, whose moves weakened vaccine recommendations.
Why it matters

One Leerink analyst says Democrats have "bigger fish to fry" than drug prices for now.
Why it matters
“It's a new day in Washington”
Science advocates want answers for cuts to research grants.

Ultragenyx, a US drugmaker for rare diseases, is laying off 20% of its staff.
It wants yearly research spending at half of what it spent in 2025, with $350 million proposed for 2027.
It is ending UX701, a gene therapy for Wilson disease, an inherited illness, because too few patients did well enough.
It is also winding down GTX-102 after a final trial failed in September in Angelman syndrome, a rare brain disorder.

AbbVie buys a gut drug Nxera stepped back from
Swipe up for the story ↑Scroll down for the story ↓
AbbVie, the drug giant behind Humira and Skyrizi, will pay $100 million up front for a gut drug from Nxera.
It may pay up to $1.37 billion more as the drug advances and sells, plus a share of sales.
Who is involved
The drug, NXE0033744, is a pill for inflammatory bowel disease, or IBD, in which the gut stays inflamed.
How it got here
Late last year
Nxera pulls back
Now
AbbVie takes it on
Nxera, a drug company once called Sosei, pulled back from this project late last year while cutting staff.
How it got here
“very, very complex and expensive”
Its chief called IBD a "very, very complex and expensive" area in which to develop a drug.
Why it matters
Humira
Skyrizi
Rinvoq
AbbVie already sells Humira, Skyrizi and Rinvoq for IBD.
How it works
Pharmacologists call such a drug gut-restricted, and Nxera says its first trial found this one stays in the gut.
How it works
It switches on a receptor called EP4 in the gut, hoping to calm swelling and heal the lining.
Seen it before
A hose aimed at one plant leaves the rest of the garden dry.
The truth
Nxera's chief says AbbVie must now find out whether this biology really helps people with IBD.
How it works

FDA speeds its review of a chemo-free cancer pair
Swipe up for the story ↑Scroll down for the story ↓
The FDA, the US drug regulator, gave a fast review to BeOne Medicines' blood cancer pill, Brukinsa.
Who is involved
Brukinsa
a pill
Rituximab
an antibody drug
BeOne is a cancer drug company.
Today's usual first treatment is rituximab with bendamustine, a chemotherapy, which brings toxic side effects, BeOne says.
A final trial, MANGROVE, enrolled 510 patients across 157 sites.
Why it matters
If approved, it would be the first chemotherapy-free option of this kind for these patients, BeOne says.
How it works
Cancer doctors call it progression-free survival: the time until the cancer worsens or the patient dies, which MANGROVE measured.
How it works
Overall survival is a separate goal in MANGROVE, so this result does not yet show that patients live longer.
Seen it before
A runner can be timed to her first stumble, and that says little about the finish.

Guinea-Bissau may give the baby vaccine sooner
Swipe up for the story ↑Scroll down for the story ↓
Guinea-Bissau, a small West African country, may start giving hepatitis B vaccine at birth early next year, not in 2028.
Who is involved
Walter Kazadi Mulombo
WHO's representative
Walter Kazadi Mulombo, WHO's representative there, told the BBC that officials are considering the change.
Babies there now get their first dose at 6 weeks, which works less well.
Nearly a fifth of the people there have hepatitis B, a viral infection of the liver.
How it got here
1 of 2
babies, half without the birth dose
A US-funded trial would have kept the birth dose from half of 14,000 newborns.
Why it matters
25 of 100
chronic infections that end in death, at most
Infection in infancy often lasts for life.
How it works
Research ethics says a trial should not withhold a proven treatment, and that was WHO's objection here.
Seen it before
A coach would not test a new helmet by sending half the team out with none.
The truth
The university behind the trial says it never started and no baby was enrolled.
Good news
WHO says it is working with the government to bring the birth dose forward.
Good news
Guinea-Bissau is considering giving hepatitis B vaccine to newborns early next year instead of in 2028.

Swallowed gut bacteria cut infections after transplants
Swipe up for the story ↑Scroll down for the story ↓
16 of 16
strains of bacteria in one treatment
A swallowed mix of 16 strains of gut bacteria, SER-155, was tested in people getting donor stem cells.
Who is involved
Doctors do such transplants about 40,000 times a year, aiming to cure blood cancers.
Bloodstream infections hit 10% of those on the treatment and 43% of those on a dummy.
Only 34 people in the comparison had a transplant: 20 on the treatment and 14 on the dummy.
This was a phase 1b trial, an early test of safety.
The treatment was as safe as the dummy in this trial, and it caused no infections of its own.
Why it matters
These patients are at high risk of bloodstream infections, and such infections are a main danger after the transplant.
How it works
Microbiologists call it engraftment when added bacteria settle in the gut, and all 16 strains in SER-155 did.
How it works
The transplant disturbs gut bacteria and weakens the gut wall, which raises the risk of blood infection.
Seen it before
A lawn thick with grass leaves little room for weeds.
The truth
8 people died during the study, including 2 on the treatment and 2 on the dummy in this comparison.
Nobody knows yet
Whether SER-155 really cuts bloodstream infections.
In 34 people the statistical range runs from a huge cut to no effect, and the treated group also had an antibiotic first.
Good news
In a small early trial, 10% of transplant patients on a swallowed dose of gut bacteria got a bloodstream infection, against 43% on a dummy.

A cell treatment doctors can dial up shrinks melanoma
Swipe up for the story ↑Scroll down for the story ↓
Doctors gave a cell treatment, amsoki-cel, to 37 people with advanced melanoma that immune drugs had failed to stop.
10 of 15
patients whose tumours shrank
Tumours shrank in 10 of the 15 patients given the chosen dose, and disappeared in 2 of them.
Who is involved
It is made from immune cells called TILs, taken from the patient's tumour and given back.
How it got here
The first patient had swelling around a tumour in the brain, so doctors cut the top dose by 80%.
No patient died from the treatment, and none needed intensive care.
Why it matters
These patients' melanoma has outlasted immune drugs.
How it works
Cell engineers call this regulatable: the cells' growth signal, IL-15, is controlled by a second drug, acetazolamide.
How it works
After the first patient, doctors also cut that second drug's dose by 75%.

An HIV antibody works, then resistant virus gets through
Swipe up for the story ↑Scroll down for the story ↓
Researchers looked again at 2 trials of VRC01, an antibody given by drip to prevent HIV.
The trials ran in the Americas and sub-Saharan Africa, with infusions for 80 weeks.
Against the virus strains most sensitive to it, the antibody prevented 66.3% of infections.
As the antibody faded after the last doses, HIV diagnoses in the antibody groups rose above the dummy group.
Why it matters
It could matter most for people who cannot use prevention pills, and in high-HIV parts of sub-Saharan Africa.
Why it matters
The authors say several antibodies together will probably be needed.
How it works
Evolutionary biologists call this selective pressure: the antibody stops sensitive strains, so resistant ones are what get through.
Seen it before
Spray a field and only the weeds the spray cannot kill come back.
Nobody knows yet
Whether several antibodies together would stop resistant HIV.
The authors say several are probably needed, and this analysis looked at VRC01 alone.

Scientists map how TB's vital genes work together
Swipe up for the story ↑Scroll down for the story ↓
Scientists have mapped how the essential genes of tuberculosis bacteria work together, in a paper in Nature on Wednesday.
Who is involved
Tuberculosis is the world's deadliest germ.
Using CRISPR, a gene tool, the team turned down 2 genes at a time in the same bacterium.
They tried it first in a related lab bacterium, covering 787 genes and about 2.3 million pairs of CRISPR guides.
The maps found thousands of links nobody had recognised.
Why it matters
The authors say the maps can guide the design of drug combinations.
How it works
Geneticists call this a genetic interaction: turning down 2 genes does more or less harm than the two added up.
How it works
That gap shows which genes depend on each other, and so which drug pairs might work best together.
Seen it before
Take away one of two lamps and the room stays lit, but take both and it goes dark.

Scientists mapped more than 1 million cells across glioblastoma tumours, in work reported in Nature.
Who is involved
Glioblastoma is the most common brain cancer in adults, with average survival of 12 to 18 months.
They found that the cancer cells organise themselves in a consistent pattern from patient to patient.
Who is involved
Wellcome Sanger Institute
Britain

The work came from Britain's Wellcome Sanger Institute and partners including Germany's cancer research centre.
Why it matters
Surgery is hard because these tumours spread through the brain.
Why it matters
Future drugs could aim at the early cells before they turn into resistant ones.
How it works
Cancer biologists call this plasticity: tumour cells change state, and the atlas shows they do it in a predictable order.

Swapping salt could save lives, a model says
Swipe up for the story ↑Scroll down for the story ↓
A study by The George Institute for Global Health estimates that potassium-enriched salt could prevent 2.96 million deaths a year.
The team looked at 193 countries, assuming everyone switched from ordinary salt.
Who is involved
This salt replaces some sodium chloride with potassium chloride, and it looks, tastes and cooks like table salt.
Swapping only the salt used at home could prevent 1.85 million deaths.
How it got here
The World Health Organization endorsed this salt in 2025.
Why it matters
70 of 100

In Europe and North America, more than 70% of salt comes from processed and restaurant food.
How it works

Portugal tries sterile mosquitoes as dengue rises
Swipe up for the story ↑Scroll down for the story ↓
Portugal released 30,000 sterile male tiger mosquitoes in September, its second attempt to shrink their numbers.
By the end of October, Italy had 76 dengue cases caught locally and France 8.
How it got here
1990s

Now
in France, Spain, Germany and beyond
Tiger mosquitoes came to Italy in the 1990s in shipments of used tyres, and they spread dengue, chikungunya and Zika.
The mosquito moves about 60 kilometres north each year, partly in cars.
Why it matters
Travellers bring the virus back, a local mosquito bites them, and it then infects someone else.
Why it matters
EU health officials now test wastewater at big airports to spot dengue before patients reach a doctor.
How it works
Insect scientists call this the sterile insect technique: sterilised males mate, but no offspring follow, as Portugal hopes.

A nasal MS drug hits one goal, at its lower dose
Swipe up for the story ↑Scroll down for the story ↓
Tiziana Life Sciences, a London and Boston biotech, tested a nasal drug, foralumab, in 48 people with multiple sclerosis (MS).
Who is involved
MS is a disease of the brain and nerves.
Brain scans showed less inflammation at the 50 microgram dose than on a dummy.
All 48 finished the 12 weeks, and no serious side effects were linked to the drug.
Tiredness scores improved by 6.17 and 7.18 points on the two doses.
Why it matters
No US-approved drug is aimed at this form, so these patients have no treatment made for them.
How it works
Doctors call a scan like this a surrogate endpoint: it stands in for how patients fare.

A gene keeps bone's stem cells in reserve, in mice
Swipe up for the story ↑Scroll down for the story ↓
Researchers at NYU Langone Health found that a gene, HOXA10, keeps a lifelong supply of bone stem cells in mice.
90 of 100
of the stem cells and their descendants gone
They deleted the gene in 6-day-old mouse pups, in a study in Science Advances.
Mice without the gene could not heal breaks properly.
In bone samples from people, silencing 3 related genes cut stem cells further, and cell death rose by 50%.
Why it matters
“burns through its reserves too early”
Without the gene, bone "burns through its reserves too early", as in ageing bone, says surgeon Philipp Leucht.
How it works
Stem-cell biologists call this self-renewal: a stem cell copying itself to keep a reserve.

Why it matters
About 150,000 people in the US have essential thrombocythemia, one of these cancers, Alethio says.

Cancer groups fear losing money in the European Union's next long-term budget, for 2028 to 2034.
Who is involved
The European Commission, the EU's executive, proposes a shared fund for health, biotechnology, farming and the bioeconomy.
How it got here
The Beating Cancer Plan and the Cancer Mission both run until 2030, into the first years of that budget.
“Projects that are making a real difference”
"Projects that are making a real difference" now face an uncertain future, says Isabel Rubio of the European Cancer Organisation.

A cleaner way to edit genes in marmosets
Swipe up for the story ↑Scroll down for the story ↓
Researchers injected gene-editing tools into marmoset eggs just before fertilisation, in a paper in Scientific Reports.
Who is involved
Marmosets are small monkeys with short pregnancies and early maturity, so labs use them to make animals with altered genes.
Editing an embryo often leaves a mosaic, in which some cells are changed and others are not.
Before fertilisation
edit the egg
About 8 hours after
DNA copying starts
The team found that a marmoset embryo starts copying its DNA about 8 hours after fertilisation.
3 of 3
genes changed
They made marmosets with changes in 3 genes, and all were likely free of mosaics.
Why it matters
Marmosets take years to breed a second generation, so getting the first animal right saves years of waiting.
How it works
Geneticists call this avoiding mosaicism: an edit made before the DNA is copied reaches every later cell.
Seen it before
Change a recipe before the cakes bake and every cake changes, but halfway through only some do.
