Abstract
Vaccine adjuvants comprising a liquid medium contain polymers with anionic constitutive repeating units and hydrophobic constitutive repeating units. Advantageously, the adjuvants are aqueous solutions of partially esterified polyacrylic acids. The novel adjuvants are highly stable, effective and have a relatively low level of local toxicity. Further, vaccines comprising such adjuvants and a process for producing them are described.
