Different vaccines may differ somewhat, but about one of them I read that full immunity isn't achieved for about four weeks. If that is correct, airlines might (?) require travellers to have been vaccinated at least a month before flying. A last minute jab might not be enough.
As I understand it, you get the jab and your body has some initial reaction quite quickly, but then your immune system more slowly ramps up what it needs to fight Covid-19 more specifically. I think, it isn't yet clear that EVERY vaccinated person's immune system will respond strongly enough, but if yours does, encountering the virus means not only that will you not get sick, but also that you are very unlikely to spread it on to others. This is different to normal asymptomatic carriers without the vaccine. So that's good.
Good too. If you had Covid already you probably won't get sick when you meet it again because at least for a while, you have natural immunity. Less good, is that individual immune response after having Covid seems even more variable than individual response to the vaccine. They don't exactly know why. (Maybe the amount of virus that initially entered your body, but maybe something else.)
On the face of it, it seems stupid for airlines to require ALL passengers to be vaccinated, surely anyone who had had Covid and recovered shouldn't need it. However, because non vaccination immunity now seems more variable, it MAY be the case, at least with some airlines, and/or some countries, that ALL passengers must get it. Or, maybe more likely (??) they might say proof of antibodies is enough.
Then, come 2022, who knows what "Best Practice" will be.
