Like all the other potential candidates, one being developed in Russia by Gamalei National Research Centre for Epidemiology and Microbiology, in partnership with the Russian Defence Ministry, is also far from being ready at this point. Numerous reports on Sunday had claimed that clinical trials for a Russian vaccine had been โ€œsuccessfullyโ€ completed. What most of these reports did not specifically mention is that only phase-I of the clinical trials had been completed. Phase-II trials began Monay 13th July 2020 while there is no clarity over phase-III trials. Allow me to educate you a little bit about vaccine development;

A. ๐—ฃ๐—ฟ๐—ฒ-๐—–๐—น๐—ถ๐—ป๐—ถ๐—ฐ๐—ฎ๐—น ๐—ฑ๐—ฒ๐˜ƒ๐—ฒ๐—น๐—ผ๐—ฝ๐—บ๐—ฒ๐—ป๐˜

This is the first stage of vaccine development and usually involves animal testing.

B. ๐—–๐—น๐—ถ๐—ป๐—ถ๐—ฐ๐—ฎ๐—น ๐——๐—ฒ๐˜ƒ๐—ฒ๐—น๐—ผ๐—ฝ๐—บ๐—ฒ๐—ป๐˜

This stage sees the vaccine being tested on humans. Which involves 3 phases.

๐—ฃ๐—ต๐—ฎ๐˜€๐—ฒ ๐Ÿญ: Safety and tolerability of the vaccine is tested.

๐—ฃ๐—ต๐—ฎ๐˜€๐—ฒ ๐Ÿฎ: This phase expands the scope of the clinical trials and assesses the effectiveness of the vaccine against simulated infections.

๐—ฃ๐—ต๐—ฎ๐˜€๐—ฒ ๐Ÿฏ: a vaccine is tested on hundreds of participants across multiple locations, with the hope of evaluating efficiency against natural disease conditions.

In the case of Russian candidate vaccine, as with any other candidate, the success of phase-II trials, which could take at least couple of months, is not guaranteed. The success can only be ascertained after the completion of the trials.

Currently we've got 150 candidate vaccines for coronavirus being developed all over the world. Nearly half of these are still in pre-clinical stages, meaning they are being tried on animals or are still in early stages of development. About 15 vaccines are in phase-I trials and about ten in phase-II trials. Three vaccines are in phase-III trials which include Oxford University, Sinopharm and Sinovac. The earliest time we can expect a successful completion of Phase 3 and approval is September.

Meanwhile lets remember to wear a mask, sanitize and observe social distance.
