Dr Susan Hopkins told Sky News some measures may have to stay in place beyond that, until more is known about COVID-19 transmission, so “we can release everything and get back to life as it was”.
Speaking on a special programme, COVID Crisis: Learning The Lessons, she admitted it was “difficult to say” if rules this summer could be tighter than they were during the same period last year.
“One of the things we’ve learned is that when people go on holiday, perhaps they drop their guard a bit, perhaps they mingle a bit closer and they mingle in groups,” Dr Hopkins said.
“That may be one of the areas in which spread of infection can occur.
“So I think we are going to have to have some measures in place until the whole population is vaccinated, at least all of the adult population.
“And even then I think we’ll need to know more about transmission before we can release everything and get back to life as it was.”
