Conjugated meningococcal capsular saccharides will be introduced into immunisation schedules in the near future, but the phenomenon of "carrier suppression" must first be addressed, particularly where multiple conjugates are to be used. In the invention, tetanus toxoid is used as the carrier protein, even where multiple meningococcal conjugates are administered at th e same time and where a patient has previously been exposed to the carrier protein, either in the form of a previous immunogen (e.g. in a DTP vaccine) or as a previous carrier protein (e.g. in a Hib or pneumococcal conjugate vaccine). The invention provides a method for immunising a patient, comprisi ng administering multiple conjugates of meningococcal capsular saccharides, wherein each conjugate comprises a tetanus toxoid carrier protein, and the capsular saccharide, and wherein the patient has been pre-immunised with a tetanus toxoid.
