Russia Claims Breakthrough Ebola Vaccine Could Protect Against Rare Bundibugyo Strain Amid Africa Outbreak Concerns
Russian scientists have reportedly developed a new vaccine targeting a recently identified strain of the Ebola virus, with early claims suggesting it may also protect against the rare Bundibugyo strain currently linked to outbreaks in parts of Africa.
The announcement was made by Russian Health Minister Mikhail Murashko and later shared by the Russian Embassy in South Africa through a post on X.
According to the statement, researchers in Russia believe the vaccine could help protect against the Bundibugyo variant of Ebola, which has been associated with recent cases reported in the Democratic Republic of the Congo (DRC).
The development comes at a time when health authorities across the world are closely monitoring fresh Ebola outbreaks in Africa and searching for broader medical solutions capable of protecting against multiple strains of the deadly virus.
Amid the growing concern, the World Health Organization (WHO) on May 17 declared the Ebola outbreaks in the Democratic Republic of the Congo and Uganda a Public Health Emergency of International Concern (PHEIC) under the International Health Regulations (IHR) 2005.
India’s Ministry of Health and Family Welfare, citing information from the Africa Centres for Disease Control and Prevention (Africa CDC), said the ongoing spread of the Bundibugyo strain in both countries has also been classified as a Public Health Emergency of Continental Security (PHECS).
Health authorities are particularly worried because the Bundibugyo strain is considered rare, and currently there are no approved vaccines or targeted treatments specifically designed to combat it.
To strengthen international preparedness, the WHO’s IHR Emergency Committee issued temporary recommendations on May 22 urging countries to tighten disease surveillance measures at airports, border crossings and other entry points.
The advisory specifically called for closer monitoring of travellers arriving from regions where Bundibugyo virus cases have been detected, especially those showing symptoms such as unexplained fever or signs of severe illness.
The WHO has also discouraged non-essential travel to affected areas until the outbreaks are brought under control.
According to India’s Health Ministry, countries sharing borders with the Democratic Republic of the Congo and Uganda — including South Sudan — are currently considered at high risk for possible transmission of the disease.
Ebola is a severe viral haemorrhagic fever caused by infection with different strains of the Ebola virus. The illness can spread rapidly and is known for its high fatality rate, especially in areas with limited healthcare infrastructure.
Medical experts say the emergence of new vaccine research is encouraging, particularly because broader protection against multiple Ebola strains remains one of the biggest challenges in global outbreak preparedness.
While Russia’s announcement has generated attention, scientists and health agencies are expected to closely examine clinical data and trial results before the vaccine’s effectiveness against the Bundibugyo strain can be independently verified.
