Russian Coronavirus vaccine, Sputnik V, which has created a buzz around the world for its fast-tracked testing procedure, has entered the "civil circulation" in the country. But Russian cosmonauts, soon going for the International Space Station, have refused to take the shot.

Sergei Ryzhikov from Roscosmos, the leader of the next expedition to ISS which will happen in October, on Thursday, September 24, said, "I'd personally say that I would not get vaccinated because I tread very carefully on this issue."

The astronauts including Ryzhikov were wearing face masks during an online news conference at the Star City training center outside the Russian capital. Their comments about the COVID-19 vaccine came after President Vladimir Putin announced that the country developed an effective vaccine against the virus within a limited time and named the vaccine as "Sputnik V"—after the Soviet-era satellite which was launched in 1957.

As per reports, another astronaut from the Russian crew, Sergey Kud-Sverchkov said, "As soon as the vaccine is tried and tested and proves its reliability then a decision will be taken to recommend that cosmonauts get vaccinated." He also added that the immunization decision is not up to them but to the doctors who are responsible for looking after the astronauts' health. According to the Ryzhikov, the ISS is currently the safest place and the astronauts do not have to be vaccinated because "we strictly follow all sanitary rules."

However, Russia's vaccine development has created a controversy among the researches, as many experts expressed that they are doubtful how effective Sputnik V would work. They also questioned the efficacy of the vaccine which received its approval before the completion of the clinical trials.

But many people in Russia, especially high-profile personalities have taken shots of Sputnik V—including Moscow Mayor Sergei Sobyanin and Defence Minister Sergei Shoigu—meanwhile, Putin also said that his daughter was also immunized.

Russian Healthcare Minister Mikhail Murashko said on Friday, September 25 that "today post-registration clinical studies are conducted. There are over 3,500 patients who have received this vaccine. Everything is proceeding as normal."
