I don't understand why there is a debate on this? Surely it should be implemented as soon as possible (taking into consideration the availability of vaccines for all those who want to travel). The government need to step up and make some tough decisions and make sure that the fabulous work down with our vaccination programme isn't undone. It's done for yellow fever and that's a vaccine people have to pay for. If there's a valid reason people can't have the vaccine they can get an exemption certificate. And I've never heard anyone complaining about it?
