I don’t see how covid passports have any impact on the spread of the virus, when the vaccine doesn’t stop you from contracting it? You could have a pub with half jabbed/half un-jabbed, and every person who’s been jabbed could test positive?
The only covid GUIDANCE there should be is:
• Get the vaccine and booster if you feel comfortable to do so.
• If you don’t feel well, stay at home.
• If you have any symptoms that could be covid, get tested.
• If wearing a mask makes you feel better protected, wear one.
