The announcement on the vaccine was made by Russian Health Minister Mikhail Murashko, as per an X post by the Russian Embassy in South Africa.

Speaking on the effectiveness of the vaccine, the X post said: "According to the Russian scientists, the vaccine may also protect against the rare Bundibugyo strain linked to the outbreak in the #DRC."

Meanwhile, As a deadly Ebola strain continues to spread in the Democratic Republic of the Congo (DRC), with cases confirmed in neighbouring Uganda, the UN aviation agency is urging governments and flight operators to closely follow guidelines put in place following the COVID-19 pandemic.

The outbreak of the Bundibugyo (BVD) strain is a major cause for concern in the DRC, where there have been more than 900 suspected cases and around 220 suspected deaths.

So far, there have been seven confirmed cases in Uganda. The World Health Organization (WHO) says that the outbreak, which it has declared a public health emergency of international concern, is spreading faster than health workers can contain it.

The International Civil Aviation Organization (ICAO) will update its guidance as necessary in light of the evolving situation, but for now it insists that international air services remain safe.

Clear guidance in place

On Tuesday, the UN agency called on governments and aviation stakeholders to adhere strictly to WHO recommendations to mitigate any Ebola-related risks.

The COVID-19 pandemic caused massive disruption to air travel, prompting ICAO to establish new protocols for rapid, standardised information sharing among States, airlines, airports, and health agencies.

Digital innovations such as electronic health declarations and contactless border processes have been integrated into ICAO’s recommendations to track and manage health risks more effectively, and the agency is coordinating with WHO and its Member States to provide measures to prevent the transmission of the disease through air travel.

These measures are also designed to protect the health of aviation personnel and passengers, reassure travellers, and keep flight cancellations to a minimum.
