Unfortunately, the jury is still out on whether one would be immune after already having it. There is some promising research being done using the serum of people who have recovered to make a makeshift "vaccine" (although not a technical one).

The only thing we can say with any certainty is that you are more likely to get a severe case the more often you are exposed to the virus. So, if you are exposed to it 80 times, you are more likely to have a severe version. The quantity of viral particles is key, which makes it interesting. It is a "common cold" virus, so immunity is probably only for a few years at best.

It is one virus- the cold virus- that has mutated.
