How about this Daily Mail article then?
In the article Tony Blair is quoted as saying "only if people can easily show whether they are clear of coronavirus will industries such as international travel be able to restart." How can we prove we are free of coronavirus other than by proof of vaccination (tests are out of date from the moment they are done)? Yes we can refuse to be tested, refuse to get the ID card, refuse to download the app (its bound to be available for our phone) etc, but that means our freedom of choice will be limited eg unable to go to large public events, concerts etc. and we will not be able to fly. So what about those of us who have close family elsewhere in the world. What it will come down to is "get vaccinated or don't see your loved ones!" So depressing!
