Description

technical field

[0001] The invention relates to a vaccine adjuvant composition, in particular to a compound vaccine adjuvant composition for animals. Background technique

[0002] "Adjuvant" generally refers to any substance that increases the humoral or cellular immune response to an antigen. An adjuvant is used for two purposes: it slows the release of antigen from the injection site, and it stimulates the immune system; it allows smaller doses of antigen to be used to stimulate a similar immune response, reducing the cost of manufacturing the vaccine. Thus, the potency of certain antigens can be significantly increased when the antigen is combined with an adjuvant.

[0003] Porcine reproductive and respiratory syndrome is caused by porcine reproductive and respiratory syndrome virus (porcine reproductive and respiratory syndrome virus, PRRSV), which is characterized by fever, abortion in sows, increased mortality of piglets before and after weaning, respiratory disorders...
