I recently read in the news that countries are thinking to offer a "green passport" based on the vaccination against SARS-CoV-2, allowing vaccinated people to do things with less restrictions than the non-vaccinated :
If those passports are to be put in place, why do they not include people that were exposed naturally to SARS-CoV-2, this number being bigger days after days (60 millions people, 17/02/2021) ?
Does that mean that vaccines offer more immunity than being exposed naturally to SARS-CoV-2 and recover ?
My questions don't address the ethical aspect of implementing a "green passport", I'm only trying to figure out if vaccination offers more immunity than being exposed to the virus. A possible answer to this question can simply be "we don't know so far" because of the lack of feedback on a long term view.
