Mr Putin did not give any name for the vaccine, nor did he say how it worked, who was developing it or give details of any trials.
He said “corresponding tests” had revealed the new drug to be “more effective” than any of the many trialled since the outbreak of the deadly haemorrhagic fever two years ago.
“We have good news,” Mr Putin was quoted as saying by RIA Novosti news agency. “We have registered a drug against Ebola, which after the corresponding tests has been shown to be highly effective, more effective than the drugs used worldwide up to now.”
Experts working on other vaccine trials poured scorn on his claim, saying the Russian drug was in the early stages of testing. They described his claim of superiority as “mind-boggling”.
Ban Ki-moon, the United Nations Secretary General, appealed to world health authorities to maintain “vigilance” to prevent the return of Ebola as the West Africa epidemic which claimed the lives of 11,000 people was declared officially over on Thursday at the UN General Assembly.
The WHO confirmed that with the release last month of Liberia’s two last patients from hospital, “all known chains of transmission have been stopped in West Africa”.
