If that's the case, out of curiousity why there has been numerous reported cases of people that catched covid again after already recovering from it?

Edit: So... after reading the article I'm not sure this is the case for all people as this research has been done only on a group of asymptomatic & low/mild response people. IMHO for a sentence like that to be valid, it should be demonstrated on the other part of the population, those that have a high immune response against the virus and end up in a critical state from it.

There have been many, many news articles that speculate about this, but to date, I'm aware of two papers that document re-infections. Both papers isolated and sequenced the viruses involved, and both papers documented re-infection with significantly mutated variants of the same virus.

Yes, here is an example of a paper that mentions a re-infection with significant genomic differences between the two samples: https://www.thelancet.com/journals/laninf/article/PIIS1473-3...
