| 摘要 |
<p>The invention concerns a vaccine composition comprising two valences; (i) a first valence which is adjuvant-enhanced with aluminium hydroxide and (ii) a second valence which contains a polysaccharide of bacterial capsule comprising one or more -O- acetyl groups and which is not adsorbed with aluminium oxide due to the presence of a protecting compound which may be a phosphate, a citrate or a carbonate and which prevents said adsorption. The first valence can be any vaccine valence. In one particular embodiment, the vaccine composition contains (i) the Hepatite A valence, adsorbed on aluminium hydroxide and (ii) the typhoid fever valence formed by the polysaccharide Vi of the Salmonella typhi capsule.</p> |
