Reports said that researchers tried the vaccine on themselves
As Russia plans to register the world's first coronavirus vaccine on August 12, the chief of the lab developing the vaccine has given some hints on how it will work.
The vaccine has been developed jointly by the Gamaleya Research Institute and the Russian Defence Ministry, reports Livemint.
Gamaleya National Research Centre Director Prof Alexander Gintsburg said that vaccines used inanimate particles created on the basis of adenovirus, the report said citing Sputnik News.
There are no concerns that the vaccine could potentially cause harm to an individual's health, he said.
"The particles and objects that can reproduce their own kind are the ones that are considered alive. The particles in question cannot multiply."
The professor said some people naturally have a fever when the immune system of the person receiving the vaccine receives a powerful boost, but this "side-effect" can easily be overcome by taking paracetamol.
Reports said that Prof Alexander Gintsburg and other researchers tried the vaccine on themselves.
Earlier, Russian Health Minister Mikhail Murashko said that members of "risk groups," such as medical workers, may be offered the vaccine this month.
Deputy Prime Minister Tatyana Golikova pledged to start "industrial production" in September, and Murashko said mass vaccination is likely to begin as early as October.
While Russia is getting prepared to register the vaccine, top US infectious disease specialist Dr Anthony Fauci sounded a note of caution.
He said: "I do hope that the Chinese and the Russians are actually testing a vaccine before they are administering the vaccine to anyone, because claims of having a vaccine ready to distribute before you do testing, I think, is problematic at best."
In April, President Vladimir Putin ordered state officials to shorten the time of clinical trials for a variety of drugs, including potential coronavirus vaccines.
The World Health Organization (WHO) said all vaccine candidates should go through full stages of testing before being rolled out.
