WHO Steps Up Ebola Response, Prioritises Vaccine Testing Amid Outbreak
WHO Steps Up Ebola Response, Prioritises Vaccine Testing Amid Outbreak
The World Health Organisation (WHO) has intensified global efforts to contain the ongoing outbreak of Ebola disease caused by the Bundibugyo virus, convening top scientific and advisory groups to urgently evaluate experimental vaccines and therapeutics as cases continue to emerge in the Democratic Republic of the Congo (DRC), with additional cross-border infections reported in Uganda.
The latest outbreak has raised fresh concerns among international health authorities because the Bundibugyo ebolavirus is one of the less common species of Ebola virus, and currently has no licensed vaccine or approved therapeutic treatment, unlike the more common Zaire ebolavirus for which approved countermeasures exist.
In a statement released after a high-level emergency consultation, WHO said its expert advisory groups concluded that all promising medical countermeasures for Bundibugyo virus disease (BVD) should only be deployed within carefully designed clinical trials to ensure scientific evidence generation while maintaining strict safety and ethical standards.

The organisation disclosed that the review involved its R&D Blueprint Technical Advisory Group, the Strategic Advisory Group of Experts on Immunisation (SAGE), and WHO’s Ebola Vaccine Working Group, which assessed all available vaccine and treatment candidates for immediate deployment feasibility.
WHO said the current outbreak underscores a major research gap in global preparedness for non-Zaire Ebola strains, particularly the Bundibugyo species, which caused significant outbreaks in Uganda in 2007 and the DRC in 2012, with fatality rates ranging between 25 and 50 per cent, according to historical outbreak data.

For treatment of confirmed infections, independent experts prioritised three investigational therapeutics for immediate clinical trial evaluation.
These include the monoclonal antibody MBP134, Maftivimab®, and the antiviral drug remdesivir, all of which have shown potential antiviral activity against filoviruses in preclinical and limited clinical settings.
The advisory groups also endorsed testing combination therapy involving a monoclonal antibody and remdesivir to determine whether combined treatment could improve survival outcomes.
WHO stressed that none of these interventions should be administered outside structured clinical protocols.
For post-exposure prophylaxis among individuals who have had direct contact with confirmed or probable cases, experts identified the oral antiviral obeldesivir as a priority candidate.
The strategy involves rapidly administering oral tablets to exposed contacts to assess whether infection can be prevented before symptom onset.
However, WHO warned that this approach depends heavily on rapid case detection and effective contact tracing, both of which remain operational challenges in some affected communities due to security concerns and difficult terrain.
On vaccines, WHO identified the single-dose rVSV Bundibugyo vaccine, developed by the International AIDS Vaccine Initiative (IAVI), as the most promising candidate for future trial deployment.
The vaccine is estimated to require seven to nine months before becoming trial-ready.
A second candidate, ChAdOx1 Bundibugyo, developed by the University of Oxford in collaboration with the Serum Institute of India, could be available for efficacy trials within two to three months, pending additional animal safety and immunogenicity data.
Experts said a single-dose vaccination strategy could be suitable for immediate ring vaccination of contacts of infected persons, while a two-dose regimen may be more appropriate for frontline health workers and other high-risk responders.
The panels also reviewed Ervebo, currently the world’s only licensed Ebola vaccine.
Although Ervebo has proven highly effective against Zaire ebolavirus, WHO said there is currently no conclusive evidence that it offers protection against the Bundibugyo strain.
As a result, the organisation advised that Ervebo should not be used outside rigorously controlled research settings specifically designed to evaluate possible cross-protection.
WHO said it is collaborating closely with the governments of the DRC and Uganda, the Africa Centres for Disease Control and Prevention (Africa CDC), the French National Agency for Research on AIDS and Viral Hepatitis (ANRS), and other global partners to fast-track ethical clinical trial protocols.
The organisation emphasised that all research activities must meet the highest international ethical standards, with affected communities actively involved in decision-making and national authorities maintaining oversight.
WHO also called for accelerated deployment of essential laboratory supplies, stronger surveillance systems, enhanced community engagement, and coordinated international funding to support rapid evaluation of Bundibugyo-specific countermeasures.
Despite the accelerated research push, WHO reiterated that the immediate priority remains containing transmission through established Ebola control measures, including rapid diagnosis, case isolation, contact tracing, infection prevention and control, community education, safe burials, and intensive surveillance.
Health officials warned that while scientific progress offers hope, effective outbreak containment will depend primarily on swift public health action and strong regional cooperation.

NAFDAC Raises Alarm Over Toxic Pesticides in Beans, Seizes ₦800m Banned Chemicals
The National Agency for Food and Drug Administration and Control (NAFDAC) has raised the alarm over the detection of dangerous pesticide residues in some samples of beans sold in Nigeria, warning that the misuse of agricultural chemicals poses serious risks to public health.
The agency also disclosed that it seized banned agrochemicals worth more than ₦800 million in Ogun, Ondo, Osun and Oyo states in 2025, as part of efforts to prevent prohibited chemicals from entering the food supply chain.
NAFDAC Director-General, Professor Mojisola Adeyeye, disclosed the findings during a media briefing on pesticide safety in Lagos on Friday, October 9, 2026.
According to the agency, a recent market study detected residues of pyrethroids and dimethoate above permitted safety limits in some bean samples, raising concerns about the improper use of pesticides to preserve harvested agricultural produce.
Adeyeye explained that although pesticides play an important role in crop protection, their use must comply with approved regulations and safety instructions.
She warned that the misuse of chemicals, excessive application and failure to observe the prescribed waiting period between pesticide application and harvesting could expose consumers, farmers and the environment to harmful substances.
The NAFDAC chief stressed that a pesticide approved for use on crops in the field is not automatically suitable for preserving harvested food products.
She specifically cautioned against using dimethoate to preserve harvested beans against pests such as weevils, noting that the chemical was not approved for that purpose.

While certain pyrethroids are permitted for post-harvest storage under approved conditions, she said users must follow the prescribed instructions and safety requirements.
Adeyeye identified common violations to include applying excessive quantities of pesticides, using products on crops for which they were not approved, harvesting before the recommended waiting period and improperly mixing chemicals.
She also warned against storing pesticides alongside food, animal feed or household items, reusing empty chemical containers for domestic purposes and disposing of pesticide waste carelessly.
NAFDAC Seizes Banned Chemicals Worth ₦800m
Providing details of the agency’s enforcement operations, Adeyeye said NAFDAC seized banned agrochemicals worth more than ₦800 million in Ogun, Ondo, Osun and Oyo states in 2025.
She added that enforcement operations in the North-West between September 2024 and July 2026 resulted in the seizure, interception or recovery of 2,974 cartons of pesticides containing paraquat, valued at approximately ₦148.7 million.
The agency also intercepted 120 cartons of pesticides containing chlorpyrifos, valued at more than ₦17 million, during the same period.
In a separate operation in Kebbi State, authorities intercepted 5,619 cartons containing 67,428 litres of paraquat, alongside 500 cartons of atrazine products.
The agency said the affected chemicals were among products prohibited under its regulatory measures, with the applicable phase-out periods for paraquat, chlorpyrifos and atrazine ending on January 1, 2026.
NAFDAC also disclosed that it sealed four unauthorised pesticide and agrochemical manufacturing facilities in Bichi, Kano State, in July 2026. Officials reportedly discovered unlabelled products, bulk chemicals and packaging materials associated with illegal production.
Adeyeye said suspects had been arrested in connection with enforcement operations, with one case undergoing prosecution.
She attributed the continued circulation of banned pesticides partly to illegal importation, unauthorised local production and distribution through unofficial supply channels.
The agency also announced restrictions on the 100-millilitre pack size of dichlorvos, prohibiting its importation, manufacture and sale in open markets and supermarkets because of concerns about its misuse on agricultural produce and other risks.
NAFDAC Warns Farmers, Dealers and Consumers
Adeyeye urged farmers to purchase pesticides from recognised agro-input dealers, use only approved products and follow label instructions, including recommended quantities and pre-harvest waiting periods.
Manufacturers, importers, distributors and retailers were also warned to comply with regulatory requirements, while businesses involved in illegal production and distribution could face enforcement action and prosecution.
The agency said it was strengthening surveillance, laboratory testing, inspections and collaboration with law enforcement authorities to identify and remove prohibited chemicals from circulation.
It has also trained more than 2,000 agro-input dealers on responsible pesticide handling and application, while expanding its enforcement zonal offices from three to six to improve regulatory coverage.
Deputy Director of Veterinary Medicine and Allied Products at NAFDAC, Dr Idayat Mudshiru, said continued engagement with farmers and other stakeholders was essential to reducing pesticide misuse.
She said the agency was working with industry stakeholders, including CropLife, to improve public awareness and promote safe handling and application of agricultural chemicals.
The agency emphasised that protecting Nigerians from harmful pesticide residues requires coordinated action across the agricultural value chain, from chemical manufacturers and importers to dealers and farmers.
The findings underscore the importance of food safety monitoring and proper pesticide management, particularly for staple foods such as beans that are widely consumed in Nigerian households.

NAFDAC Disowns Viral Fake Products List, Warns Nigerians of Misinformation
NAFDAC Disowns Viral Fake Products List, Warns Nigerians of Misinformation
The National Agency for Food and Drug Administration and Control (NAFDAC) has warned Nigerians against circulating a viral social media list alleging that several products sold in the country are fake, adulterated or substandard, saying the list is not an official communication from the agency.
The warning comes amid growing concern among consumers over the authenticity and safety of products available in Nigerian markets, with unverified claims circulating online about food, beverages, medicines and other consumer goods.
NAFDAC cautioned that sharing unconfirmed allegations could mislead the public, trigger unnecessary panic and damage the reputation of legitimate manufacturers, distributors and retailers.
The agency stressed that the appearance of a product or brand on a social media list does not automatically establish that it is counterfeit, adulterated or unsafe for consumption or use.
According to the regulator, claims about the safety or quality of products must be assessed through appropriate regulatory procedures, including investigations, product sampling and laboratory testing where necessary.
NAFDAC also explained that official product alerts and recall notices contain verifiable information about the affected products and any regulatory action taken. Consumers were therefore urged to distinguish between confirmed safety warnings and claims circulated by individuals or unofficial social media accounts.
The agency advised Nigerians to consult its official communication channels for information on product recalls, safety alerts, counterfeit medicines and substandard consumer goods before acting on or sharing such claims.

It further encouraged consumers to report suspected fake or adulterated products to the appropriate authorities for investigation rather than relying solely on viral posts.
NAFDAC warned that the indiscriminate circulation of unverified product allegations could have serious consequences for businesses whose products are wrongly identified, while also making it more difficult for consumers to distinguish genuine safety warnings from misinformation.
The agency’s position highlights the importance of verifying product-related information, particularly when allegations involve widely used brands or essential household items.
Consumers should check the details of any official warning, including the product name, batch number, registration details and instructions issued by the regulator. Where a specific product has been recalled or flagged, the applicable notice should guide consumers on whether to stop using it or take other recommended precautions.
The public is also encouraged to report suspicious products, misleading labels and suspected counterfeit goods through NAFDAC’s official reporting channels.
The agency reiterated the importance of protecting public health and urged Nigerians to verify claims before sharing them online.
Consumers should note that the warning about the viral list does not mean every product named in it has been independently cleared as safe. The status of any particular product should be determined through verified regulatory information and applicable official notices.

‘We Are Ignorant, We Don’t Read’ — NAFDAC DG Raises Food Safety Concerns
‘We Are Ignorant, We Don’t Read’ — NAFDAC DG Raises Food Safety Concerns
The Director-General of the National Agency for Food and Drug Administration and Control (NAFDAC), Prof. Mojisola Adeyeye, has said poor understanding of food safety guidelines and regulatory responsibilities remains a major challenge in Nigeria.
Adeyeye made the remarks while explaining the roles of government agencies in regulating food products and agricultural practices across the country.
“We are ignorant in this country. We are very ignorant. We don’t read. We don’t understand,” the NAFDAC DG said.
She explained that several government agencies are responsible for different stages of the food chain, from production on the farm to consumption, stressing that NAFDAC’s mandate primarily covers processed and semi-processed foods.
According to Adeyeye, the Federal Ministry of Agriculture has the primary responsibility for fresh agricultural produce sold in markets.
“NAFDAC mandate is for processed or semi-processed foods. So the oranges you buy in the market, we don’t control the oranges you buy in the market,” she said.
However, she said NAFDAC has regulatory responsibilities when pesticides are used in agricultural production because the agency approves, regulates and controls such products.
Adeyeye said NAFDAC works with the Ministry of Agriculture to train farmers on the proper use of pesticides, including the quantity to apply and the appropriate period between treatment and harvesting.

She said some farmers may misuse agricultural chemicals because they do not fully understand instructions on pesticide labels.
“We have about 56 per cent illiteracy. If it’s a literate country, they will read: ‘Put one teaspoon in one gallon.’ Sometimes our people don’t understand. And they think the more you put, the better,” she said.
The NAFDAC chief said the agency’s Veterinary Medicine and Allied Products Directorate also trains farmers and other stakeholders on the appropriate use of pesticides.
She, however, noted that NAFDAC cannot independently reach the entire farming population because of the number of farmers across the country.
“We cannot go to one million farmers in Nigeria. NAFDAC cannot do that. It is the Ministry of Agriculture that should be doing that,” Adeyeye said.
She added that while NAFDAC has an obligation to support farmer education because of its role in regulating pesticides, the Ministry of Agriculture should take the lead in educating farmers on fresh produce and agricultural practices.
Adeyeye also said many Nigerians do not understand the specific responsibilities of government agencies involved in food regulation, resulting in misplaced expectations about what NAFDAC can regulate.
The comments come amid continuing concerns over food safety, pesticide misuse, counterfeit products and consumer protection in Nigeria.
Adeyeye disclosed that NAFDAC receives more than 200 complaints from Nigerians through its complaint channels each month. The agency also reported receiving 225 complaints involving suspected counterfeit products in August.
She said complaints from consumers provide important leads for NAFDAC’s investigations and enforcement activities.
The agency has continued to urge Nigerians to pay attention to product information, follow safety instructions and report suspected counterfeit, substandard or unsafe products through its established channels.
