I'm not sure how you can argue that immunity or vaccine passports won't reduce transmission. This the classic false dichotomy that if it isn't 100% effective then it's useless.
Ok, firstly, I didn’t mention immunity. An unvaccinated person may be immune but atm they still have to test. Secondly, I’m not saying that ‘it’s useless’, I’m saying that it doesn’t guarantee that someone is immune so we shouldn’t be assuming that they are and exempting them from testing/isolation etc as the passport currently allows. Exempting potentially infectious people from testing allows transmission to occur where testing would not.
Other countries also include proof of recovery from infection as proof of immunity.
@Foliageeverywhere122 yes, some classes may be more popular than others but, in general, I do not think lecturers are as ‘up close and personal’ with their students compared to a teacher and the rooms do tend to be bigger.
