The most recent ONS figures suggest 1 in 10 people are carrying antibodies.
Some 10% of the UK population is showing signs of recent infection, a doubling since October, says ONS.

Meanwhile I was listening to Radio 2 on my drive to work earlier and on the Jeremy Vine show they were talking about the vaccine. Susan Mitchie, "a Sage Scientist", was proffering the standard dose of doom and gloom. Her suggestion was that even after vaccination we should continue with the current measures for quite some time and we shouldn't get excited about lifting restrictions soon. She suggested we need 90% of the population to be immune one way or the other before we relax restrictions, even then some precautions will still be needed.
Her justification was that
a) there is no evidence the vaccine reduces transmission
b) there is no evidence the vaccine prevents long covid
c) some people won't or can't have the vaccine and vaccinated people might carry the virus and give it to the unvaccinated people who might then get very ill and might die.
