Coronavirus: Experts cast doubt on UK plan for ‘herd immunity’ ‘We really don’t know whether there will be herd immunity or not,’ says head of virology at National Institute for Biological Standards and Control Health Correspondent Friday 13 March 2020 15:31 Article bookmarked Find your bookmarks in your section, under my profile Don't show me this message again ✕ Experts have cast doubt on the government’s policy of letting large numbers of the British population catch in a bid to create "herd immunity", warning it may not work and people could be susceptible to catching it again.
On Friday, the UK’s said a level of herd immunity – where a significant proportion of people recover and become immune to the infection – was desirable and could protect the public in the event the virus became a seasonal infection.
He told Sky News: “Communities will become immune to it and that’s going to be an important part of controlling this longer term.
“About 60 per cent is the sort of figure you need to get herd immunity.” Read more But leading scientists and officials warned there is no guarantee people will become permanently immune to the virus, and said it is too soon to know what could happen as the virus spreads through the population.
Dr Nicola Rose, head of virology at the National Institute for Biological Standards and Control, said: “Obviously contain and delay is the approach being taken in the UK and in a number of different countries.
The approaches are really to buy time in context of the healthcare system and time for vaccines to be developed.
“We don’t know how the pandemic will evolve.
With flu for example it comes and goes in waves.
This may well be the case here.
We really don’t know whether there will be herd immunity or not.

It is early days really with this virus to understand what that looks like.
I think we’re a long way from what we would technically call herd immunity.” She said it would only be after people had been infected and their immune response analysed that the true picture could be established around whether people were immune to further infection.
Professor Hanneke Schuitemaker, global head of viral vaccine discovery for Janssen Vaccines, said: “We don’t know how long natural immunity will last.
And if people who have experienced the infection will be protected forever thereafter or whether we will need vaccines to support them that gives continuous protection against reinfection.” On the variation between different countries’ attitudes on how best to tackle the virus, she added: “I think all governments should look at countries where measures have failed and try to do better.
And that’s why I don’t understand why we don’t have a European approach.” More about 1 /1 Coronavirus: Experts cast doubt on UK plan for ‘herd immunity’ Coronavirus: Experts cast doubt on UK plan for ‘herd immunity’ ‘We really don’t know whether there will be herd immunity or not,’ says head of virology at National Institute for Biological Standards and Control Comments Share your thoughts and debate the big issues ✕ About The Independent commenting Independent Premium Comments can be posted by members of our membership scheme, Independent Premium.
