Virologist Wants Upgrade Of New Malaria Vaccine
Dr Solomon Chollom, Jos-based virologist, has called for the upgrade of the new malaria vaccine to what he called a “pan-malarial vaccine.”
Chollom explained that the “pan-malarial vaccine” is a vaccine that would confer protection against more than one strain of Plasmodium which would take care of all the species of Plasmodium that are responsible for malaria fever globally.
Dr Chollom, who is also the spokesman of the Plateau Inter-professional Health Committee on COVID-19 Response, made the call in an interview with on Tuesday in Jos.
He said that the recently approved malaria vaccine, RTS, S by the World Health Organisation (WHO) which is also called Mosquirix, was worth celebrating.
He, however, said that the new vaccine, though safe and efficacious, could not be completely relied upon to treat malaria because it was only efficacious against Plasmodium Falciparium, which was just one of the four species of Plasmodium responsible for malaria.
“The vaccine cannot be completely relied upon to eradicate malaria globally since it confers protection against just one of the four species of Plasmodium responsible for malaria fever globally.
“It is then pertinent for the upgrade of the vaccine to a “pan-malarial vaccine” that would confer protection against all species of Plasmodium responsible for malaria fever globally.
“When this is done, we will be looking forward to the eradication of malaria and not merely scaling down on the global burden,” the virologist said.
According to him, upgrading the vaccine to a “pan-malarial vaccine” is better and shorter because mosquirix is only a subunit, not a whole vaccine.
“This way, the antigenic units of other species of Plasmodium not captured in the present formula could be processed to enrich the formula for more effective immune response against all malaria-causing species and strains of Plasmodium,” he said.
He further said that based on the information released on the new vaccine’s clinical trials, which indicates a 77 per cent efficacy, it means that it is above the threshold of 75 per cent.
This, he said, implied that the product was well formulated with good prospects.
Chollom said that since the vaccine was highly recommended for children, there was need to recalibrate the formula to scale down on the number of shots needed to achieve maximum immune response.
“At the moment, children must take four shots of the vaccine, which is cumbersome and could create attrition and dropout as children are known to have phobia for injections,” he added.
Two United States scientists who unraveled the human micro RNA have won the Nobel Prize in Physiology or Medicine 2024.
Victor Ambros and Gary Ruvkun won the coveted prize for their work on microRNA as their discoveries help explain how complex life emerged on earth and how the human body is made up of a wide variety of different tissues.
MicroRNAs influence how genes – the instructions for life – are controlled inside organisms, including humans.
Every cell in the human body contains the same raw genetic information, locked in our DNA.
However, despite starting with the identical genetic information, the cells of the human body are wildly different in form and function.
The electrical impulses of nerve cells are distinct from the rhythmic beating of heart cells. The metabolic powerhouse that is a liver cell is distinct to a kidney cell, which filters urea out of the blood.
The light-sensing abilities of cells in the retina are different in skillset to white blood cells that produce antibodies to fight infection.
So much variety can arise from the same starting material because of gene expression.
The US scientists were the first to discover microRNAs and how they exerted control on how genes are expressed differently in different tissues.
The medicine and physiology prize winners are selected by the Nobel Assembly of Sweden’s Karolinska Institute.
They said: “Their groundbreaking discovery revealed a completely new principle of gene regulation that turned out to be essential for multicellular organisms, including humans.
“It is now known that the human genome codes for over 1,000 microRNAs.”
The World Health Organisation (WHO) has begun acting to curb effects of antibiotic pollution.
The new guidance on wastewater and solid waste management for antibiotic manufacturing sheds light on this important but neglected challenge ahead of the United Nations General Assembly (UNGA) High-Level Meeting on antimicrobial resistance (AMR) taking place on 26 September 2024.
The emergence and spread of AMR caused by antibiotic pollution could undermine the effectiveness of antibiotics globally, including the medicines produced at the manufacturing sites responsible for the pollution.
Despite high antibiotic pollution levels being widely documented, the issue is largely unregulated and quality assurance criteria typically do not address environmental emissions. In addition, once distributed, there is a lack of information provided to consumers on how to dispose of antibiotics when they are not used, for example, when they expire or when a course is finished but there is still antibiotic left over.
“Pharmaceutical waste from antibiotic manufacturing can facilitate the emergence of new drug-resistant bacteria, which can spread globally and threaten our health. Controlling pollution from antibiotic production contributes to keeping these life-saving medicines effective for everyone,” said Dr Yukiko Nakatani, WHO Assistant Director-General for AMR ad interim.
Globally, there is a lack of accessible information on the environmental damage caused by manufacturing of medicines.
“The guidance provides an independent and impartial scientific basis for regulators, procurers, inspectors, and industry themselves to include robust antibiotic pollution control in their standards,” said Dr Maria Neira, Director, Department of Environment, Climate Change and Health, WHO. “Critically, the strong focus on transparency will equip buyers, investors and the general public to make decisions that account for manufacturers’ efforts to control antibiotic pollution.”
In a concerted effort to curb brain drain, the Kebbi State Government has harmonised medical doctors’ salaries to be at par with their colleagues in the federal government’s tertiary health facilities.
Kebbi State Commissioner for Health, Musa Inusa-Isma’il, disclosed this at the handing over of ambulances to the state-owned health facilities at the Ministry of Health in Birnin Kebbi yesterday.
Inusa Isma’il, according to a statement by Ahmed Idris, the Chief Press Secretary to the governor, said the essence of the harmonisation was to retain the existing medical doctors and attract more to the services of the state.
According to him, the doctors across the state had already started enjoying the new salaries from August 2024.
He said the release of the vehicles was in fulfilment of Governor Nasir Idris’ promise to uplift health care services in the state.
“His Excellency said I should inform you, the beneficiaries of this gesture, that the vehicle should be strictly used for the intended purpose. It should not be used for anything else.
“If there is no referral case, each of the vehicles must be parked at the hospital by 6 pm. The governor said you should warn your drivers against reckless driving as well as violating the instructions.
“We should also do everything possible to reciprocate the gesture by working according to the terms and conditions attached,” he advised.
The benefiting health facilities included Sir Yahaya Memorial Hospital, Birnin Kebbi; State Teaching Hospital, Kalgo; General Hospital, Argungu; General Hospital, Yauri; General Hospital, Zuru; and General Hospital, Bunza.
In his speech, the permanent secretary of the ministry, Dr Shehu Koko, recalled that the ambulances were handed over to the ministry last Friday by the governor for the onward handover to the benefiting hospitals.
He observed that the ambulances would go a long way in improving the referral system in the state, adding that delays in reaching the secondary and tertiary facilities would be eliminated.
The permanent secretary attributed the high rate of maternal mortality in the country to delays in getting to the health facilities for proper medical care.
“We believe with the provision of these ambulances, part of the gaps we have in our referral system will be addressed, whereby patients who require secondary healthcare could be easily transported to secondary and tertiary health centres, where they can get such help,” he said.
In a goodwill message, Commissioner for Information and Culture Alhaji Yakubu Ahmed expressed gratitude to the governor for the support he has given to the ministry to excel.
While advising the beneficiaries to use the vehicles judiciously, the commissioner advised that services and maintenance of the vehicles must be prompt to derive the maximum benefits from the vehicles.
The commissioner also highlighted some achievements recorded by the government in the last year, including beautification of the state capital, completion of a multimillion-naira ultramodern state secretariat, road construction, construction and renovation of classrooms and upgrading of some health facilities, among others.
