Toxoids: antigens derived from toxins, immune responses neutralizes virulent toxins associated with the disease (e. g. td) is an inactivated version of the toxin boosters needed every 10 years. Conjugate polysaccharide vaccine: the second generation, composed of the capsular polysaccharide bound to protein carrier (e. g. pneumococcal, hib, meningococcal) and may reduce asymptomatic transmission of disease. Live attenuated vaccines: eliminate pathogenic properties without killing them or inactivating their antigenic properties (e. g. rotavirus, mmr, varicella)
