According the report in The Lancet, over 76 participants of these trials would be monitored up to 180 days and more rigorous phase 3 clinical trial was planned with the involvement of 40,000 volunteers from different age and risk groups.

“Large, long-term trials including a placebo comparison, and further monitoring are needed to establish the long-term safety and effectiveness of the vaccine for preventing COVID-19 infection,” The Lancet said.

Earlier, Russia had said that it is planning to produce 6 million doses of coronavirus vaccine per month. The RIA news agency cited Russian Industry Minister Denis Manturov as saying that Russia is planning to produce between 1.5 million and 2 million doses per month of its potential coronavirus vaccine by the year end.

In another development, Russia had said it is looking for a partnership with India for producing COVID-19 vaccine Sputnik V.

Russian President Vladimir Putin had announced that his country has developed the world’s first vaccine against COVID-19, which works quite effectively and forms a stable immunity against the disease.

The Sputnik V vaccine consists of two shots that use different versions of adenoviruses — virus types, some of which cause the common cold — that the manufacturers have engineered to carry the gene for the surface protein of SARS-CoV-2 that causes COVID-19.
