Lockdown and vaccine rollout helped us - Van-Tampublished at 17:33 British Summer Time 28 April 2021
On the number of people who have received a Covid vaccination, Prof Van-Tam highlights that the peak of a third virus wave was around 24 January - when at that point the UK "didn't really have very many people vaccinated at all".
He says it is epidemiologically true to say that "most of the steady decline that we've seen, the disappearance of our third wave has been down to efforts of the British people in following lockdown".
He says the vaccine has "undoubtedly helped in the later stages", with good evidence showing among other things that the death rate had dropped faster in the older age groups than in the young.
He says it is important to note that the vaccine rollout is the way out of getting out of "trouble" of the same size and magnitude ever again.
