Russia has become the first country in the world to register a coronavirus vaccine for use.
Vladimir Putin, the country’s president, announced one of his daughters has already been inoculated.
The move comes despite many scientists in Russia and abroad questioning the decision to make the vaccine available for use before Phase 3 trials, which normally last for months and involve thousands of people.
Speaking at a government meeting on Tuesday, Putin said that the vaccine has proven efficient during tests, offering a lasting immunity from the coronavirus.
Putin said that his daughter had a temperature of 38 degrees Celsius on the day of the first vaccine injection, and then it dropped to just over 37C on the following day.
After the second shot she again had a slight increase in temperature.
“She’s feeling well and has a high number of antibodies,” Putin added. He didn’t specify which of his two daughters received the vaccine.
The Health Ministry said in a statement on Tuesday that the vaccine is expected to provide immunity from the coronavirus for up to two years.
Russian authorities have said that medical workers, teachers and other risk groups will be the first to be inoculated.
Deputy Prime Minister Tatyana Golikova said that the vaccination of doctors could start as early as this month.
Large-scale production of the vaccine will start in September, and mass vaccination may begin as early as October, officials said.
Professor Alexander Gintsburg, head of the Gamaleya institute that developed the vaccine, raised eyebrows in May when he said that he and other researchers tried the vaccine on themselves.
Human studies started on June 17 among 76 volunteers. Half were injected with a vaccine in liquid form and the other half with a vaccine that came as soluble powder. Some in the first half were recruited from the military, which raised concerns that servicemen may have been pressured to participate.
Amid Russia’s rush to become the first to create a vaccine, the US, Britain and Canada last month accused Russia of using hackers to steal vaccine research from Western labs.
Despite not completing Phase 3 trials, Putin insisted the vaccine has undergone the necessary tests.
