British travellers who fail to take their booster jabs face renewed restrictions, The Mail on Sunday can reveal.
Plans to reimpose quarantine and testing for those who have refused their third vaccine are currently being drawn up by Ministers to protect the UK against the spread of new
coronavirus variants.
But they are likely to prove controversial if introduced before most of those eligible for their booster have received it. So far, only 60 per cent have done so.
The move would change the definition of 'fully vaccinated' from having had two jabs to three.
