COTONOU, Benin — Benin, Liberia and Sierra Leone launched large-scale malaria vaccine programs on Thursday under an Africa-focused initiative that hopes to save tens of thousands of children’s lives per year across Africa.
The three West African countries are the latest to participate after successful rollouts of routine malaria immunization for children in Burkina Faso, Cameroon, Ghana, Kenya and Malawi, the global vaccine alliance GAVI said in a statement.
The World Health Organization-approved vaccine is meant to work alongside existing tools such as bed nets to combat malaria, which in Africa kills nearly half a million children under the age of 5 each year.
“This introduction … will help save lives and offer relief to families, communities and hard-pressed health systems,” said Aurelia Nguyen, GAVI chief program officer.
Benin has 215,900 doses of the vaccine, which will be available to children from around 5 months old, according to GAVI.
Sierra Leone has 550,000 doses and neighboring Liberia has 112,000 doses, it said.
At the official launch in Benin, which took place in the town of Allada, some 54 kilometers from the country’s largest city, Cotonou, 25 children received the vaccine.
“I came to have my children vaccinated against malaria. It’s important to me because when children get this malaria disease, we spend a lot of money,” said Victoire Fagbemi, a 41-year-old mother of four.
Another mother, Victoire Boko, who had her 10-month-old child vaccinated at the launch, said the health minister’s explanations about the vaccine in the local Fon language had allayed any anxieties she had about its safety. “When I get home, I will share the information … with my neighbors and friends,” she said on the sidelines of the launch.
The African region is home to 11 countries that carry approximately 70% of the global burden of malaria, according to GAVI.

MIGORI, Kenya — As the coffin bearing the body of Rosebella Awuor was lowered into the grave, heart-wrenching sobs from mourners filled the air. Her sister Winnie Akinyi, the guardian to Awuor’s orphaned son, fell to the ground, wailing.
It was the latest of five deaths in this family attributed to malaria. The disease is common in Kenya, and it is preventable and curable, but poverty makes it deadly for those who can’t afford treatment.
In the family’s compound in the western county of Migori, three other graves are visible, that of Awuor’s husband and their other two children who died from malaria before age 2.
Awuor, 31, fell ill in December and lost her five-month pregnancy before succumbing to malaria. Her 11-year-old son is the family’s only survivor.
Malaria is still a significant public health challenge in Kenya, though some progress may be coming. Parts of Kenya participated in an important pilot of the world’s first malaria vaccine, with a reported drop in deaths for children under 5. Kenya’s health ministry hasn’t said when the vaccine will be widely available.
The biggest impact is felt in regions characterized by high temperatures like Kenya’s Indian Ocean coast, and places with high rainfall like the western region near Lake Victoria.
Kenya had an estimated 5 million malaria cases and more than 12,000 deaths reported in 2022, according to the World Health Organization. The WHO has declared April 25 as World Malaria Day.
Most of those affected are children under 5 and pregnant women.
New approaches needed
Kenya continues to combat malaria with traditional methods such as distributing bed nets that are treated with insecticides, spraying breeding areas, and promoting early diagnosis and treatment, but experts say progress against the disease with those approaches has plateaued.
Public health expert Dr. Willis Akhwale, special adviser for the Kenya End Malaria Council, said the COVID-19 pandemic slowed the distribution of drugs and treatment.
He said innovative treatment methods are needed in the wake of drug-resistant cases reported in parts of Africa.
“We need to start looking at investments in new-generation medicines. That should then be able to counter any resistance in [the] foreseeable future,” he said.
Akhwale said other needs include more funding and logistical support.
“In Kenya, the shortfall in terms of the need is almost $52 million, so we need to close that gap,” he said, citing health ministry data. He recommended domestic funding and private sector support amid donor fatigue with crises around the world.
Wilson Otieno has been admitted to a hospital three times for malaria and has received outpatient treatment countless times. It’s expensive for the 33-year-old accountant and father in the lakeside city of Kisumu.
Malaria is never “pocket friendly,” he said.
Some progress has been made with local manufacturing of crucial medication.
The Kenya-based Universal Corporation Limited last year received the WHO’s approval to produce an antimalarial drug known as Spaq, a combination of sulfadoxine-pyrimethamine plus amodiaquine.
The approval was an important step in Africa’s capacity to make lifesaving medications, a new focus for governments and public health officials after vulnerabilities were exposed by the COVID-19 pandemic. Africa relies heavily on drug imports.
“It will really help in lowering the dependency for imports as we saw during the COVID era, where whatever was being imported actually had huge supply disruptions,” said Palu Dhanani, the founder and managing director of UCL.
If you don’t get the right medicine at the right time, malaria can cause unnecessary deaths, Dhanani said.

Paris, France — World wine production dropped 10 percent last year, the biggest fall in more than six decades, because of “extreme” climate changes, the body that monitors the trade said Thursday.
“Extreme environmental conditions” including droughts, fires and other problems with climate were mostly to blame for the drastic fall, said the International Organization of Vine and Wine, or OIV, that covers nearly 50 wine-producing countries.
Australia and Italy suffered the worst, with 26 and 23 percent drops. Spain lost more than a fifth of its production. Harvests in Chile and South Africa were down by more than 10 percent.
The OIV said the global grape harvest was the worst since 1961, and worse even than its early estimates in November.
In further bad news for winemakers, customers drank 3 percent less wine in 2023, the French-based intergovernmental body said.
Director John Barker highlighted “drought, extreme heat and fires, as well as heavy rain causing flooding and fungal diseases across major northern and southern hemisphere wine-producing regions.”
Although he said climate problems were not solely to blame for the drastic fall, “The most important challenge that the sector faces is climate change.
“We know that the grapevine, as a long-lived plant cultivated in often vulnerable areas, is strongly affected by climate change,” he added.
France bucked the falling harvest trend, with a 4 percent rise, making it by far the world’s biggest wine producer.
Less wine being drunk
Wine consumption last year was, however, at its lowest level since 1996, confirming a fall off over the last five years, according to the figures.
The trend is partly due to price increases caused by inflation and a sharp fall in wine drinking in China — down a quarter — due to its economic slowdown.
The Portuguese, French and Italians remain the world’s biggest wine drinkers per capita.
Barker said the underlying decrease in consumption is being “driven by demographic and lifestyle changes. But given the very complicated influences on global demand at the moment,” it is difficult to know whether the fall will continue.
“What is clear is that inflation is the dominant factor affecting demand in 2023,” he said.
Land given over to growing grapes to eat or for wine fell for the third consecutive year to 7.2 million hectares.
But India became one of the global top 10 grape producers for the first time with a 3 percent rise in the size of its vineyards.
France, however, has been pruning its vineyards back slightly, with its government paying winemakers to pull up vines or to distill their grapes.
The collapse of the Italian harvest to its lowest level since 1950 does not necessarily mean there will be a similar contraction there, said Barker.
Between floods and hailstones, and damp weather causing mildew in the center and south of the country, the fall was “clearly linked to meteorological conditions,” he said.

new york — Russia blocked a U.N. Security Council resolution Wednesday reaffirming the need to prevent a nuclear arms race in outer space.
The measure was proposed jointly by the United States, a nuclear power, and Japan, the only nation ever to be attacked with nuclear bombs.
“We have only begun to understand the catastrophic ramifications of a nuclear explosion in space,” said U.S. Ambassador Linda Thomas-Greenfield. “How it could destroy thousands of satellites operated by countries and companies around the world — and wipe out the vital communications, scientific, meteorological, agricultural, commercial and national security services we all depend on.”
The failed text recalled the responsibility of states to comply with the 1967 Outer Space Treaty, which is the basic framework on international space law. It says outer space is to be shared among nations and shall be free of nuclear weapons or other weapons of mass destruction. The treaty also says the moon and other celestial bodies “shall be used exclusively for peaceful purposes,” and astronauts shall be “regarded as the envoys of mankind.”
The proposed resolution also called on states “not to develop nuclear weapons or any other kinds of weapons of mass destruction specifically designed to be placed in orbit around the Earth, or to be installed on celestial bodies, or to be stationed in outer space in any other manner.”
Thomas-Greenfield noted that President Vladimir Putin has said publicly that Russia has no intention of deploying nuclear weapons in space.
“And so, today’s veto begs the question: Why? Why, if you are following the rules, would you not support a resolution that reaffirms them?” she asked. “What could you possibly be hiding? It’s baffling, and it’s a shame.”
Thomas-Greenfield just returned from Japan, where she visited Nagasaki, a city on which the United States dropped one of two atomic bombs at the end of World War II.
“It was a reminder of our profound responsibility to prevent the scourge of war and ensure that no place experiences the horror of nuclear weaponry ever again,” she said.
“Adopting this draft resolution would have been a positive and practical contribution to the promotion of the peaceful use and exploration of outer space,” said Japanese Ambassador Kazuyuki Yamazaki. “If adopted, we could have demonstrated our unity in reaffirming the principle of no placement of any weapons of mass destruction in outer space and in opposing the development of such capabilities.”
The proposed resolution, which had more than 60 co-sponsors, created no new international obligations, but reaffirmed existing ones. It was supported by 13 of the 15 council members. After failing to get an amendment added to it, Russia vetoed it and China abstained.
“Today, our council is once again being involved in a dirty spectacle prepared by the U.S. and Japan,” Russian Ambassador Vassily Nebenzia said. “This is a cynical ploy. We are being tricked.”
He said Moscow wanted a text that would have gone further, banning weapons of any kind in outer space.
China’s new U.N. ambassador, Fu Cong, echoed that, saying the draft needed “other substantive elements.”
US concerns
In February, U.S. officials said Russia is developing a space-based weapon to attack satellites. They do not believe it would target people or cause destruction on Earth.
Analysts at the Washington-based Safe World Foundation think tank say on their website that Russia is most likely developing a system “that would use a nuclear explosion to create weapons effects, most likely an electromagnetic pulse (EMP), that would in turn disable or destroy satellites.”
There are thousands of satellites in space that run the gamut from sophisticated military purposes to running a car’s GPS or providing television programming.
Although the U.S. resolution was not adopted, Thomas-Greenfield said Washington would continue to pursue bilateral arms control discussions with Russia in good faith.
The U.S. also has concerns about China’s work in space, where officials say they are rapidly developing a range of counterspace weapons and using outer space to strengthen the capabilities of their military forces on Earth.
“Over the last six years they have tripled the number of intelligent surveillance and reconnaissance satellites in orbit, and they have used their space capabilities to improve the lethality, the precision and the range of their terrestrial forces,” said General Stephen Whiting, commander of the U.S. Space Command.
He spoke by phone to regional journalists Wednesday from Tokyo, where he is meeting with allies.

cologne, germany — For the past year, five fit, academically superior men and women have been spun in centrifuges, submerged for hours, deprived temporarily of oxygen, taught to camp in the snow, and schooled in physiology, anatomy, astronomy, meteorology, robotics, and Russian.
On Monday, the five Europeans and an Australian graduated from basic training with a new title: astronaut.
At a ceremony in Cologne, Germany, ESA added the five newcomers to its astronaut corps eligible for missions to the International Space Station, bringing the total to 11.
ESA has negotiated with NASA for three places on future Artemis moon missions, although those places will likely go to the more senior astronauts, according to ESA Director General Josef Aschbacher. The agency is also supplying the service module for the Orion crew capsule. ESA relies on NASA and others to get its astronauts to space.
It is only the fourth astronaut class since 1978 for the 22-country agency, chosen from among 22,500 applicants. Another 12 were selected as reservists, but were not sent to basic training. Not surprisingly, the five have resumes studded with advanced scientific and medical degrees, military training, experience flying planes, helicopters, gliders and balloons, and “leisure” activities like rowing, scuba diving, hiking, skydiving, cycling, sailing, and kayaking.
The group formed “a very good team” devoid of personal rivalry, said Aschbacher. “I told them, one of you will fly first and one will fly last, and they accepted that of course, but from the heart, not just lip service … the team spirit is very pronounced.”
Sophie Adenot, a French air force helicopter test pilot, said the group was “a fantastic crew and a fantastic team.” The moment that struck her the most was leaving the airlock for underwater spacewalk simulation when the instructor said, “Welcome to space.”
“And for me it was mind-blowing, I had goosebumps. … In a few years it is going to be me in space, not in the water with safety divers.”
When she was a girl dreaming of space travel, “I couldn’t count the number of people who told me, this dream will never come true. ‘You have unrealistic dreams, and it will never happen.’ … Listen to yourself and don’t listen to people who don’t believe in you.”
In addition to Adenot, the ESA class consists of:
— Pablo Alvarez Fernandez, a Spanish aeronautical engineer who has worked on the Rosalind Franklin Mars rover intended for a joint mission with Russia that was suspended after the invasion of Ukraine;
— Rosemary Coogan, a British astronomer who has researched radiation emissions from black holes;
— Raphael Liegeois, a Belgian biomedical engineer and neuroscientist who has researched degenerative diseases of the nervous system, and also flies hot-air balloons and gliders;
— Marco Alain Sieber, a Swiss emergency physician who achieved sergeant rank as a paratrooper during his service with the Swiss army.
The group was joined by Katherine Bennell-Pegg from Australia, who underwent training under a cooperation agreement between Australia and ESA. She remains an employee of the Australian Space Agency. It’s up to the Australian agency to find a way for her to travel in space.
Their yearlong basic training included preparation for the hostile environment encountered in space. They were exposed to multiple times the force of gravity in a centrifuge and spent hours underwater using scuba gear to float around mockups of space station modules to simulate working in zero gravity.
They learned how to recognize symptoms of hypoxia, or lack of oxygen, by experiencing it themselves in a low-pressure chamber. Survival training included dealing with potential splashdown in the ocean and staying warm in winter while waiting to be recovered in case a landing goes off course. On top of that came academic work on scientific topics and learning about the space station’s modules and equipment.
Intensive Russian language is still part of the program, even though ESA has suspended work with Russia except for the space station, where one of the working languages is Russian.

WASHINGTON — A ancient giant snake in India might have been longer than a school bus and weighed a ton, researchers reported Thursday.
Fossils found near a coal mine revealed a snake that stretched an estimated 11 meters to 15 meters. It’s comparable to the largest known snake at about 13 meters that once lived in what is now Colombia.
The largest living snake today is Asia’s reticulated python at 10 meters.
The newly discovered behemoth lived 47 million years ago in western India’s swampy evergreen forests. It could have weighed up to 1,000 kilograms, researchers said in the journal Scientific Reports.
They gave it the name Vasuki indicus after “the mythical snake king Vasuki, who wraps around the neck of the Hindu deity Shiva,” said Debajit Datta, a study co-author at the Indian Institute of Technology Roorkee.
This monster snake wasn’t especially swift to strike.
“Considering its large size, Vasuki was a slow-moving ambush predator that would subdue its prey through constriction,” Datta said in an email.
Fragments of the snake’s backbone were discovered in 2005 by co-author Sunil Bajpai, based at the same institute, near Kutch, Gujarat, in western India. The researchers compared more than 20 fossil vertebrae to skeletons of living snakes to estimate size.
While it’s not clear exactly what Vasuki ate, other fossils found nearby reveal that the snake lived in swampy areas alongside catfish, turtles, crocodiles and primitive whales, which may have been its prey, Datta said.
The other extinct giant snake, Titanoboa, was discovered in Colombia and is estimated to have lived around 60 million years ago.
What these two monster snakes have in common is that they lived during periods of exceptionally warm global climates, said Jason Head, a Cambridge University paleontologist who was not involved in the study.
“These snakes are giant cold-blooded animals,” he said. “A snake requires higher temperatures” to grow into large sizes.
So does that mean that global warming will bring back monster-sized snakes?
In theory, it’s possible. But the climate is now warming too quickly for snakes to evolve again to be giants, he said.

Sydney — Australian researchers have built an electrical generator that consumes carbon dioxide, generates electricity and admits no exhausts. They say the technology could create a new industrial-scale carbon capture method.
Scientists say too much carbon dioxide, or CO2, in the atmosphere is main driver of warming temperatures.
Researchers at the University of Queensland have created a generator that consumes carbon dioxide and produces electricity.
The carbon-negative “nano-generator” has been built by the university’s Dow Centre for Sustainable Engineering Innovation.
The prototype device uses what is known as a poly amine gel to absorb carbon dioxide to create an electrical current.
The design team acknowledges the technology needs further development and refinement but believes it could help to significantly curb global CO2 emissions.
Zhuyuan Wang from the University of Queensland told the Australian Broadcasting Corp. the concept has great potential.
“We actually just finished the proof of concept that proves this can work but the current power density and efficiency is not high enough to compete with other energy sources, like solar panel[s], like the wind turbine,” he said.
The Queensland researchers hope their prototype could have industrial applications to help, for example, power plants reduce their emissions, as well as smaller units for use at home.
Carbon capture and storage techniques are used by the oil and gas sector to try to offset its emissions of greenhouse gases. Current methods involve harnessing CO2 produced by power companies, for example, and then burying it deep underground where it becomes trapped in rock formations. There are several large-scale CO2 burial sites in the United States.
However, the Climate Council, an Australian advocacy organization, claims that carbon capture and storage technology “has not been trialled and tested – anywhere in the world – at the scale required to tackle the climate crisis.”
Australia’s national science agency, the Commonwealth Scientific and Industrial Organisation, states that “emissions of CO2 from fossil fuels make the largest contribution to climate change.”
Australia is the world’s 14th highest emitter, contributing just over 1% of global emissions. It has, however, some of the world’s highest per capita emissions. Coal and gas generate much of Australia’s electricity, but solar and wind are leading an energy transformation.
The Climate Council states that almost a third of Australia’s energy is renewable and will soon reach 50%.
