Coronavirus live updates: India's indigenous vaccine against Covid-19 Covaxin achieves remarkable feat, says ICMR

Around 20 passengers and crew coming from Heathrow airport tested positive for Covid-19 virus at five international airports — Delhi, Amritsar, Kolkata, Ahmedabad, and Chennai — after all the passengers and crew of Air India flights from London were screened using RT-PCR test in the last two days.

British drugmaker AstraZeneca Plc told Reuters on Tuesday its Covid-19 vaccine should be effective against the new coronavirus variant, adding that studies were under way to fully probe the impact of the mutation.

If the sequencing is consistent with the current strain of the virus going around in the country, then the ongoing treatment protocol, including home isolation or treatment as per case severity, will be followed.

A new set of standard operating procedures (SOPs) issued by the Centre prescribes various actions from the point of entry and in the community for all international passengers who have travelled from or transited through the UK in the past four weeks — from November 25 to December 23.
