According to BBC: Whitty says says social distancing will need to stay in place when the vulnerable have been vaccinated, as those outside of this group will still be at risk.
I don’t get this - the whole point was to save the vulnerable and the NHS (and rightly so). So why do measures need to stay in place once they are protected?
Whitty's answered that
"Population immunity will occur if we have vaccines that can reduce transmissions between people," Whitty says.
He says they have a "high degree of confidence" that the vaccine reduces the risk of serious disease "by a large amount".
But, he says, "we don't yet know if this will lead to a reduction in transmission".
"We hope we will have a vaccine that protects the person that has it and protects people around them, but we will have to wait and see over time," he says.
Whitty adds that there will be deaths "for the foreseeable future but at a much lower level".
