You do become immune, but as of writing, there is no serology testing for H1N1 that is reliable, therefore, unless you were a confirmed case that had H1N1 (and had a H1N1 positive swab), there is no way to be 100% sure that you did have the H1N1 flu.
Therefore, the advice for people is that even if they think they had the H1N1 flu already but never had it confirmed, is to just go and get the vaccine.
The only silver lining in all of this is that so far, there is no evidence that the H1N1 virus has mutated, therefore, deeming people who have previously contracted it, or received the vaccine, to be immune against it.
