摘要

Vaccine adjuvant, comprising for 100% of its mass: - from 10% to 95% of a mineral oil comprising: - from 0.05% by mass to 10% by mass, of hydrocarbon chains having less than 16 carbon atoms; - from 0.05% by mass to 5% by mass, of hydrocarbon chains having more than 28 carbon atoms; - and which has a P / N ratio, which corresponds to the ratio of the mass quantity, of the paraffinic hydrocarbon chains to the mass quantity, of the naphthenic hydrocarbon chains, between 2.5 and 3.
