Who needs to self isolate?
From today, the fully vaccinated and under-18s can sidestep app pings.
Double-dosed people must wait two weeks for their immunity to kick in before the guidance applies to them, however.
They will receive alternative advice when contacted by the NHS app.
The app will advise them to take a PCR test, and they do not have to self-isolate while they await their result.
Those who can’t comply with this replacement guidance don’t have to, as it isn’t compulsory.
