Answers: also what is the coat and core made out of the leukemia virus
A tri valent vaccine is a vaccine that has three different alive or dead strains of various viruses injected into your body to create antibodies to fight that particular disease. That's why no flu-shop is 100% effective but really does help.

a vaccine that creates ones body to bring or build up its depleted immune system.
