Hong Kong doctors detailed the case of a man who contracted COVID-19 twice in less than five months.

Yes. I was waiting for this type of evidence because everything I'm studying says that you could theoretically at least get coronavirus about 4 times a year. In other words if it doesn't kill you the first time it might the 2nd, 3rd or 4th time you get it.

Doctors say that the LONGEST you can be immune to coronavirus is only 3 months.

So, my ongoing question is: (Which there is not an answer to yet I believe is) "If you can only be immune from coronavirus for 3 months maximum does that mean that you have to get a vaccine every 2 months to stay immune to coronavirus?"

As of yet I have heard no confirmation one way or another for this question.

And then there is the even worse question of: "Is Coronavirus mutating into something resembling the common cold which no vaccine can work on because of constant mutation which might mean people are going to be dying from this sort of like from AIDS worldwide for years and years to come?"

At least 30 million people worldwide have died from AIDS since the 1980s by the way.

Coronavirus might be something that keeps on killing for the next century as well the way it presently looks.
