i have a major problem with a non-mandatory vaccine and a passport/ID system effectively legislated by business (internal UK, not talking cross border travel). You're allowing folks to choose whether to be vaccinated, as throughout UK history, and then creating a two tier society in which people can operate and function. This is willful segregation is it not? surely just make the bloody thing mandatory?
and surely there are further ramifications of employment, why should pubs and concerts allow this verification of existence while the NHS, care homes, even banks etc not do it, and if they did surely there'd be large scale problems. It's extremely poorly thought through, in my opinion.
