If my vaccination pass expires then I can't go eat, get on a plane, go to work. So it's a requirement to get another shot, the politicians/government just didn't say it out loud - typical. Last time I got the vaccine for covid I was promised 5 years. It was reduced to 5 months post-facto. Do you seriously expect me to believe it will be at least the advertised 9 months this time - or that it's going to increase?
