Can you be vaccinated against h1n1 after contracting it?

Sure: Of course, you just may not receive any appreciable value from the vaccine as you likely already have reacted and created some natural immunity. However, the h1n1 vaccine is now combined with the regular flu shot seasonally and its likely you would still realize some additional seasonal protection from those other strains.

Yes, however: One should never get any vaccines when acutely ill, so if you currently have influenza do not get vaccinated at this time. Once you have recovered from H1N1 you are likely to be naturally immune to it for a few years. Unfortunately getting flu vaccine appears to increase one's risk of getting strains of flu not in the shot! See https://tinyurl.com/zeccbso for details...
