United Kingdom may re-evaluate its new COVID travel policy for India

The UK's decision to treat fully vaccinated people arriving from India as 'unvaccinated', may be reviewed. "India has a robust platform like CoWin to register, authenticate and issue vaccine certificates, with a QR code verification, even some so-called developed countries don't have this kind of platform," the source said.

"Everybody knows that it is identical, it is been proven. We have submitted the data to EMA and the UK MHRA. They are reviewing it, I have had a personal consultation with the regulator there, they going to get back to us shortly," Adar Poonawalla, CEO of SII told CNBC-TV18.

Poonawalla said he is unable to understand "why they (countries) have not been able to come together."

"They have to be united on one regulatory quality standards, clinical trials, and for vaccine certificate approvals," Poonawalla added.

The UK government has said if a person has been vaccinated in Africa, or South America, or countries including UAE, India, Turkey, Jordan, Thailand, Russia, they will be considered unvaccinated and will have to follow quarantine rules.
