Thyreos develops herpesvirus vaccines and vaccine vectors for the animal health and human health markets. Thyreos vaccines are based on a recombinant herpesvirus platform that elicits robust immune responses without infecting the nervous system. 


Herpes simplex viruses, known for causing cold sores and genital sores, are members of the herpesvirus family. This virus family also includes varicella zoster virus, the causative agent of chickenpox and shingles, and many veterinary pathogens that share a unique property: the ability to robustly invade the nervous system and quietly reside there lifelong. Periodic reactivation of the latent infection results in the contagious shedding of infectious virus, which is often associated with mild or sometimes severe disease.

All neuroinvasive herpesviruses are amendable to Thyreos R2 vaccine implementation.
