The CDC also said yesterday that any coronavirus vaccine would, at least at first, be used under the Food and Drug Administration's emergency use authorization, and that there could be a limited supply of vaccines before the end of 2020.
"We must respect this participant's privacy", the Johnson & Johnson statement said. He also said that Deputy Prime Minister Tatyana Golikova and the head of Russia's consumer safety watchdog, Anna Popova, had both received the vaccine known as EpiVacCorona.
The development comes as Mr Putin seeks to play a leading role in battling the global pandemic that has hit Russian Federation particularly hard.
"Can you imagine.if most vaccines go to developed countries?" Russian Federation has had more than 1.3 million infections, the fourth highest globally after the United States, India and Brazil, and added a record 14,231 new cases over the last day.
Vaccine trials rely on a certain number of infections to occur.
China has said that while reasonable profits for companies are permitted, COVID-19 vaccines should be priced close to cost. Russian authorities say the "conditional" registration is similar to fast-track programmes in the West and China and will allow them to ramp up production while testing continues. "We also know that preventing this disease could require multiple vaccines and we're investing in those that we believe have the greatest potential for success".
The UK government has asked people of Indian, Asian, Afro-Caribbean origin to participate in the ongoing clinical trials, including the trials conducted by the University of Oxford-AstraZeneca, Hindustan Times reported.
A cheap campaign is being run in Russian Federation so that the vaccine being prepared by the scientists of Oxford University can be declared wrong.
Preliminary work for the trials, which aim to speed up the process of determining the efficacy of a vaccine candidate, is being carried out by hVIVO, a unit of pharmaceutical services group Open Orphan, the company said.
