I think a vaccine passport is inevitable if people want to get back to anything like normal this summer.
bottom line, you cant tie people down and forcibly inject them, but you can ask people to get a (voluntary) passport if they want to (voluntarily) travel.
To any who suggest it is against their rights and freedoms, I say what about the rights of a company to keep their staff and other customers safe, or the rights of a country to keep their populace safe from people coming in (or the rights of me to not have to sit next to someone who is choosing to put my life at risk by invading my personal space not vaccinated).
Arguably we shouldnt be travelling abroad any time soon, and should stay local, any foreign travel will be a risk, but perhaps a passport will make that risk manageable.
To those unable to have a vaccine for medical reasons (genuine ones, I dont mean being as lax as those who dont wear a face mask) I suspect there will be a medical exemption.
those who want a vaccine but have been unable to get one, that sucks and i sympathise... perhaps initially at least there could be a proof of negative tests section but even that is not ideal.
But those who choose to refuse a vaccine, but then get uppity about having their personal freedoms limited I have zero sympathy for. Millions of people are taking the vaccine, to keep not only them but others safe, but it isnt a shield.... for the vaccine roll out to be most effective as many people as possible need to be covered as well as possible. (2 people with a 70% effective vaccine sitting next to each other keeps both of them far more safe than only one of them with a 70% effective vaccine)
We need herd immunity to protect those who cant be covered and mass vaccination is the only (sane) way to get herd immunity......... I am with Spok on this one (needs of the many yada yada yada)
