<p>A compound for protecting a vertebrate against infection by helminths comprising hyaluronidase covalently coupled to an immunostimulating carrier, in preferred form, the immunostimulating carrier to which the hyaluronidase is covalently coupled comprising a copolymer of ethylenepiperazine N-oxide and N-ethylacetylethylenepiperazinium bromide (hereafter referred to as 'synpol'), and a process for protecting a vertebrate against infection by helminths comprising administration to the vertebrate of a therapeutically effective amount of a compound comprising hyaluronidase covalently coupled to an immunostimulating carrier, preferably synpol, in preferred form, the compound being administered to the vertebrate in the form of a vaccine which includes, in admixture with the compound, synpol, and a process comprising reacting hyaluronidase and an immunostimulating carrier under conditions of time and temperature to covalently couple hyaluronidase and said immunogenic carrier.</p> |
