The UK government has said that Covid-19 vaccine certification from all countries must meet a “minimum criteria” and that it is working with India on a “phased approach” to its international travel norms.

It follows Covishield, the Serum Institute of India manufactured Oxford/AstraZeneca vaccine, being added as eligible to an expanded UK travel advisory on Wednesday. But with India’s vaccine certification not on a list of 18 approved countries, Indian travellers to the UK will continue to be treated as non-vaccinated and therefore required to quarantine for 10 days on arrival.
