Parliament passed measures to introduce Covid passes on Tuesday, despite a large Tory rebellion.
From Wednesday, people in England will have to provide an NHS Covid Pass proving their vaccination status or a recent negative test to enter nightclubs and other venues where large crowds gather.
But with lateral flow tests unavailable for home delivery on the Government website at various points in the past week, those who have not been vaccinated could find it difficult to obtain a pass.
Latest data from NHS England shows almost six million people aged 12 and over have still not received a first dose of a coronavirus vaccine.
In Leeds, an estimated 95,824 had not been vaccinated by December 5.
Population analysis is based on figures sourced from the Office for National Statistics and are estimates.
