Hello, my fully vaccinated friend from a green list country flew over to us (England) for a long weekend. On her passenger locator form she gave my UK mobile number (with my permission). Test and Trace sent me a message while she was boarding her plane back home, to say she has been in close contact with someone who has Covid and should isolate. What do we do now? Can I contact them in some way to let them know it's too late?
My friend will do a test when she's back home but regulations in her country mean that if she had been in contact with someone over there, she would not need to isolate. It looks like the NHS says she should isolate because she got her double Pfizer jab from outside the UK.
