Abstract
Abstract Anti-viral vaccines for domestic animals are prepared from glycoprotein envelope whole virus or antigenic glycoprotein obtained therefrom by complexing the glycoprotein antigenic agent with a lectin, which is preferably a mitogenic lectin. The recovery of the immunizing agent from an aqueous solution or suspension is facilitated since the lectin-glycoprotein complex is readily recoverable. The mitogenic lectin administered in the vaccine with the glycoprotein antigen can enhance the anamnestic response, in effect, acting as an adjuvant.
