Pertaining to complement deficiencies, there is no cure and the treatments for complement deficiencies vary widely. The best course of action for management is usually for a patient to treat the complement deficiency as an immune deficiency and get immunized against the microbe associated with their deficiency (or best candidate). As mentioned earlier, individuals with<unk>  are increasingly susceptible to Neisseria bacterium. Recent studies have indicated that individuals with<unk>  respond well when they are immunized with tetravalent polysaccharide meningococcal vaccine, which generates anti capsular antibodies and bactericidal anti-meningococcal activity against serotypes covered by the given vaccine. The vaccine has been reported to lower the chances of reinfection by meningococci in individuals who have undergone the treatment, however the vaccine does not protect against group B meningococci and chemotherapy is recommended if full protection from all meningococci variants is desired.
