Do you REALLY need the vaccine in order to travel?

What about those people who tested positive for COVID and have recovered?

Can't we just provide proof that we had it?

I find it odd that people who get the vaccine, which the vaccine is really just meant to "lessen" the severity of catching it.

But now is almost being dubbed as "the cure"

Seems a bit odd that they'd approve someone of a passport who's had the vaccine but also has the potential to get sick versus someone who was sick and recovered from it.
