[Antitetanus prophylaxis: actual practice and cost benefit analysis of a hypothetical mass vaccination].

: The actual practice of immunoprophylaxis in a Sanitary District of Campania (Italy) is described. As everywhere in Italy, in subjects at risk (wounded) the passive immunoprophylaxis by human specific immunoglobins is currently applied: at very high cost and with unreliable protection. The Authors suggest to implement antitetanus mass vaccination, with benefits incoming from lower expenses and higher protection.
