Obviously those who've had covid should be treated the same as vaccinated, it's my understanding the immunity is similar. Unfortunately the government doesn't recognize that, so in this case uncomfortable, you have to wear a mask at all times, and risky in the sense that if you have a positive test onboard, you'll probably be disembarked.
Curious if my COVID-positive ELISA test proving I have immunity would be accepted as proof. Probably not, despite the 2 studies this month — Wash U St. Louis and another one I’d have to look up — showing that natural immunity > jab immunity.
It is more than possible that those who had covid already and recovered, have similar immunity to the vaccinated crowd.
Problem is cruise ship has only 4 to 5 hours on sailing day to board thousands of passengers. How are they to know for sure you had covid before? Does one get a certificate of recovery from a hospital?
It would be highly impractical to perform anti-body tests on all passengers in line to board who do not have vaccination docs.
