Was it Professor Sridhar?
No, It was a female academic from a London university. Indian accent, unlike Sridhar who sounds American.
Found her. Dr Deepdi Gurdasani. She is quoted on the BBC site as saying:
"although vaccines were “critical”, even once the top four priority groups are vaccinated there will still be many more vulnerable groups who will not have received a vaccine by mid-February.
“It’s really worrying this rhetoric that vaccines are this end point that will allow us to open up society when the majority of people will not be protected from infection,” she told the BBC.
“We need a long term plan so that once restrictions are eased we don’t end up exactly in the situation [of] needing yet another lockdown.”
She added that this included an effective test-and-trace system and quarantine measures at borders."
She was basically saying no travel, no kids in school, no nothing until the virus disappears in a puff of smoke. Which is probably fine if the only single thing you have to worry about is Covid. But there are lots more things the government has to think about.
