As of current scenario, it is a setback for Sputnik, Covaxin and Sinovac as these are still not recognised internationally. That means vaccine passport with any of these vaccines may not be valid. Good thing is, Covaxin has sent its phase 3 data to The Lancet. Hopefully, it will be recognised soon. If we go a year back there was a breaking news about stocks in US going sharply high due to first trial of vaccine by Moderna pharmaceutical on 45 patients all recovered within days.
