According to reports im mainstream media (and we have to not that growing signs of scepticism in print and broadcast news about the government's handling of the pandemic and the push to inject us all with dodgy vaccines that will not make is immune are most welcome,) well-placed government sources, miniosters and scientific advisers are still pushing the idea that the (failed) contact tracing system should remaine in place because it is possible for people to catch and pass on Covid even if fully vaccinated. "There is still a risk of getting the virus and spreading it on," said one.
This means millions of human sheep who rushed to get their vaccine without first checking that the vaccines on offer are safe and effective (figures not reported in mainstream media show they are neither,) and have now had two doses of vaccine could still be made to spend 10 days at home if the NHS alerts them that they have been in close contact with an infected person.
Close contact is defined as having a face-to-face conversation, being within one metre for one minute or within two metres for 15 minutes. Not even a subsequent negative test would be enough to allow them to end their quarantine.
