All you need to know about Mosquirix, the 1st malaria vaccine endorsed by WHO

The World Health Organization (WHO) has endorsed Mosquirix, the RTS,S/AS01 malaria vaccine — the first and the only till date — against the mosquito-borne disease that kills more than 400,000 people a year, mostly African children.

The vaccine acts against plasmodium falciparum -- one of five malaria parasite species and the most deadly, most prevalent in Africa. The vaccine’s trial data showed that it could prevent 4 out of 10 malaria cases over a period of four years, when four doses were administered to children. Mosquirix is the first malaria vaccine which has finished its clinical development process.

Mosquirix, is not just a first for malaria; it is the first developed for any parasitic disease. Parasites are much more complex than viruses or bacteria, and the quest for a malaria vaccine has been underway for 100 years.

WHO’s approval followed a review of a pilot programme deployed since 2019 in Ghana, Kenya and Malawi in which more than two million doses were given of the vaccine, first made by the pharmaceutical company GSK in 1987.

In clinical trials, the vaccine had an efficacy of about 50 per cent against severe malaria in the first year, but the figure dropped close to zero by the fourth year. And the trials did not directly measure the vaccine’s impact on deaths, which has led some experts to question whether it is a worthwhile investment in countries with countless other intractable problems.

Malaria research is littered with vaccine candidates that never made it past clinical trials. Bed nets, the most widespread preventive measure, cut malaria deaths in children younger than 5 by only about 20%.

Against that backdrop, the new vaccine, even with modest efficacy, is the best new development in the fight against the disease in decades, some experts said.

How malaria affects the world

Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes.

In 2019, there were an estimated 229 million cases of malaria worldwide and the death toll due to malaria was 4,09,000.

African regions carry a disproportionately high share of the global malaria burden. In 2019, the region was home to 94% of malaria cases and deaths.

How to use the vaccine

WHO has recommended that in the context of comprehensive malaria control, Mosquirix be used for the prevention of P. falciparum malaria in children living in regions with moderate to high transmission. Mosquirix is to be given in three doses between ages 5 and 17 months, and a fourth dose roughly 18 months later. 

Funds for the programme were mobilised through Gavi, the Vaccine Alliance; the Global Fund to Fight AIDS, Tuberculosis and Malaria; and Unitaid, according to WHO.

The Bill & Melinda Gates Foundation provided catalytic funding for late-stage development of RTS,S between 2001 and 2015.

Germany's BioNTech, which developed a coronavirus vaccine with US giant Pfizer, also said it aimed to start trials for a malaria vaccine next year using the same breakthrough mRNA technology.

The WHO also hopes this latest recommendation will encourage scientists to develop more malaria vaccines.

Udupi, Nov 11: A traveller reportedly lost ₹4.1 lakh after attempting to book a cab online in Udupi. 

At around 1:30 PM on November 7, the man from West Bengal searched for car rentals on Google and selected a website named "Shakti Car Rentals." Shortly after, he was contacted by someone claiming to be "Rohit Sharma," who directed him to pay a registration fee of ₹150 on the site.

After unsuccessful payment attempts via both his Canara Bank debit card and SBI credit card (without receiving an OTP), "Rohit Sharma" instructed him to pay the driver directly. But at 1:47 PM, he received messages showing deductions of ₹3.3 lakh from his SBI credit card and ₹80,056 from his Canara Bank debit card, totaling ₹4.1 lakh.

The complainant alleges fraud through a deceptive link disguised as a booking token fee. A case has been registered at Udupi Town Police Station.

Mangaluru: In a deeply tragic turn of events, a 28-year-old woman named Ranjitha, who had recently given birth but tragically lost her newborn, ended her life by suicide on Monday. She reportedly leapt from the fourth-floor window of Lady Goschen Hospital’s luggage room.

Ranjitha, whose strength and resilience had carried her through a difficult pregnancy, was scheduled for discharge on Monday. Her journey to Lady Goschen Hospital began on October 24, when she was transferred from Karkala. She was a high-risk patient, battling both hypertension and diabetes. At the time of her admission, she was just 27 weeks pregnant.

Due to the complexities of her health, doctors made the difficult decision to perform an emergency C-section on October 30. She delivered a baby girl, premature and weighing only 960 grams. The newborn was immediately moved to the Neonatal Intensive Care Unit, where doctors did all they could. Despite these efforts, the baby passed away on November 3.

Ranjitha’s sorrow was profound. She stayed under hospital care even after her initial recovery and was preparing to go home on November 9. She had even requested a couple more days at the hospital, seeking time perhaps to cope with her unimaginable grief.

On the day of her discharge, a discharge card ready and her family eagerly waiting to take her home, Ranjitha reportedly made her way to the luggage room in the early hours. There, standing on a cot placed for patients' family members, she climbed to a window and fell from the fourth floor. Despite the attempts of another visitor to intervene, tragedy was inevitable. She was rushed to Government Wenlock Hospital, where doctors confirmed the worst—she was no more.

Dr. Durgaparasad M R, the Medical Superintendent at Lady Goschen Hospital, shared his grief and spoke of the ongoing investigation. A post-mortem is to be conducted, and the local Tahsildar will complete the necessary inquest procedures. Ranjitha’s exact reasons for taking this step are yet to be confirmed, though the weight of her recent losses paints a sorrowful picture.

Iran’s Islamic Revolution Guards Corps (IRGC) has killed or captured 69 terrorists linked to the Israeli spy agency Mossad during a major counterterrorism drill in the country's southeast, its spokesman says.  

General Ahmad Shafaei, the spokesman for the “Martyrs of Security” drill, said Friday that a total of 23 terrorists have been killed and another 46 arrested in various clean-up operations ever since the IRGC Ground Force launched it in the Sistan and Baluchestan province on November 1.

Seven terrorists have also turned themselves in during the period.

“The undeniable fact about terrorists is that they rely on arrogant powers, particularly the intelligence service of the wicked and vicious Zionist regime," Shafaei said.

“Unfortunately, weapons and munitions at terrorists’ disposal are among the most sophisticated ones in the world. This accounts for their heavy dependence.” 

The official stated that several members of the disbanded terror teams were non-Iranian nationals, who had been hired by foreign intelligence agencies to carry out acts of sabotage and terror inside Iran.

In a most recent operation, six terrorists were arrested and four others were eliminated, three of whom were non-Iranians, he added. 

On October 26, ten members of Iran's law enforcement forces were killed in a terrorist attack in the Gohar Kuh district of Taftan in the Sistan and Baluchestan province.

The so-called Jaish al-Adl terrorist group claimed responsibility for the assault, which was one of the deadliest in the province in recent months.

The group has carried out numerous terrorist attacks in Iran, primarily in Sistan and Baluchestan.

Its tactics include the abduction of border guards as well as targeting civilians and police stations within the province to incite chaos and disorder.

In January, Iran launched a military operation during which the headquarters of the Pakistan-based terrorist group was targeted in missile strikes, destroying its infrastructure.
