It's ridiculous that we don't have even the simplest restrictions here, which could save lives. Masks, for a start. It's hardly a massive sacrifice to wear one and it can reduce the risk of transmission, particularly if combined with scrupulous hygiene. Social distancing would obviously make a big difference, though the hospitality industry would presumably lobby hard against that being re-introduced. That's why we should have vaccination passports.
Scientists are warning of the danger of relying totally on vaccination to prevent a winter wave of infection, which could cost many lives and put massive pressure on the NHS. It appears that the government isn't listening and again won't act until its hand is forced, ie if the death toll rises in winter.
I can see why Singapore is going to charge the unvaccinated for medical care. There are many people here who have been unable to get the medical treatment they need, eg cancer operations, because the NHS is overburdened by Covid. My daughter was one of them and we ended up going private in desperation. People who could have the vaccine but choose to refuse, and then get very ill and need intensive hospital care, are putting pressure on the NHS that could have been avoided if they had just had the damn vaccine.
As for the rather tasteless remark about making the unvaccinated wear a yellow star - a more appropriate symbol would be a big "S" for selfish.
