Union heath secretary Rajesh Bhushan has said the government had never spoken of inoculating the entire country when a coronavirus vaccine is approved. "I want to make it absolutely clear. I repeatedly say that before discussing the topics related to science, it would be good to know the factual information about it and then analyse it. So the vaccination of the whole country was never spoken of," he said on Tuesday when asked by when the government would be able to vaccinate the whole country.
The Supreme Court on Tuesday weighed in on the local authorities' practice of pasting cautioning posters outside the homes of COVID-19 patients.

The government on Tuesday said it had found no reason to stop the Oxford vaccine trials in India after reviewing a Chennai volunteer's allegation of serious adverse effects, including memory loss and change in behavior.

Scientists at the University of Pennsylvania and the biotech firm Regeneron are investigating whether technology developed for gene therapy can be used to make a nasal spray that will prevent infection with the new coronavirus.

England on Wednesday ended a month-long lockdown but most of the country remained under restrictions as a new regional system for cutting coronavirus infection rates kicked in.
