Russian Covid 19 Vaccine – Is it Truth or Bluff – Burning Issue – Free PDF Download

RUSSIAN VACCINE

• Like all the other potential candidates, one being developed in Russia is also far from being ready at this point.
• Numerous reports on Sunday had claimed that clinical trials for a Russian vaccine had been “successfully” 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 are supposed to start Monday, while there is no clarity over phase-III trials.

What is the candidate vaccine being developed in Russia?

• There is only one candidate vaccine being developed in Russia which has reached the human clinical trial stage. That candidate, being developed by the Gamalei National Research Centre for Epidemiology and Microbiology, in partnership with the Russian Defence Ministry, had begun phase-I human trials on June 18, with 18 volunteers from the armed forces having been chosen for administering the vaccine.

So, will there be phase-III if phase-II trials do succeed?

• 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.
• It is not clear as of now whether the Russian candidate vaccine would go through phase-III trials. Usually, that is the case, but recently, considering the current emergency situation, a candidate vaccine developed in China.

What happens after phase-III?

• There are over 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.
• Even after the successful completion of phase-III, it usually takes several months before a vaccine is accessible to a general public. Several rounds of regulatory and administrative approvals are required. That is why several scientists, and even WHO officials, have been maintaining that it would be take at least 12-18 months before any Coronavirus vaccine is able to hit the market.
