Hello Anmol

Taking into consideration the present corona virus pandemic your question is completely valid. Russia claiming to successfully prepared a covid-19 vaccine should have supplied it to the world, but the process of providing a vaccine is not that simple.

The vaccine has paased the initial human trials, so now it would undergo mass trials in Russia first. Then if the vaccine works then only Russia would start its mass production and then it would sell the vaccine to the world and make profit from the vaccine.

So its basically a race between nations to prepare a vaccine to the global pandemic and then sell it to other nations and earn huge profits, and Russia is definitely leading the race at the present moment.

So I hope my answer would have cleared all your doubts. Still if you have any queries or doubts feel free to ask.

Thanks.

Manufacturing is going in start in few days ,and vaccine would be available in market till September,As each serum vaccine requires a time to be kept in isolated type environment ,by Russia if everything goes right, according to predictions.

Thank you
