A global stockpile of Ebola vaccines can be used to protect frontline health workers in high-risk countries routinely, rather than just as an emergency measure during outbreaks, international vaccine group Gavi said on Thursday. A stockpile of half-a-million Ebola vaccine doses was established by Gavi and other global health partners in 2019 for use in outbreaks of haemorrhagic fever, which has an average fatality rate of roughly 60%. Around 11,000 people died in a 2014-16 outbreak in West Africa, the largest ever.
But while highly deadly, Ebola outbreaks are relatively rare. Around 208,000 doses of the stockpiled Ervebo vaccine, made by Merck , were set to expire this year if unused, although some countries have already had doses shipped to them for preventative campaigns, including Democratic Republic of Congo and Uganda. Now there are around 120,000 doses close to expiry.
Gavi said it will fund preventative use of Ervebo routinely for high-risk countries, including transport and vaccination costs, after the World Health Organization (WHO) last month recommended using it this way. The vaccines are also still available for use in outbreaks. The WHO also backed preventative use for high-risk groups of the other Ebola vaccine, Zabdeno, made by Johnson & Johnson , with a booster dose, Mvabea, made by Bavarian Nordic .
This vaccine is not currently held in the stockpile. Both vaccines target the Ebola Zaire strain of the virus, rather than the Sudan strain that caused an outbrea.
