Why herd immunity is unlikely to wipe Covid out
At the beginning of the pandemic, scientists speculated that around 60 to 70% of people might need to be immune to the virus to hit the “herd immunity” threshold.
More than 75 per cent of adults in the UK have had both doses of the vaccine and more than 90 per cent have Covid-19 antibodies, either from infection or vaccination.
At the beginning of the pandemic, scientists speculated that around 60 to 70 per cent of people might need to be immune to the virus to hit the “herd immunity” threshold.
