Does having meningococcal disease give you immunity?

I know having chicken pox means for the rest of your life you're immune to it. Is meningitis like that? Does it have long term effects like chicken pox?

    Whether infection results in life-long immunity is not clear, but life-long immunity is unlikely due to the nature of the immunizing antigens of the bacteria, namely the capsular polysaccharide. Polysaccharides tend to be poor immunogens in general. In addition, there are several seroptypes of meningococci, and they each afford serotype-specific immunity.
