The herpes zoster vaccine developed by BCHT is a groundbreaking immunization against the varicella-zoster virus, making it the first of its kind domestically. This vaccine is derived from a high-titer attenuated varicella-zoster virus and is specifically designed to stimulate the body's immune system to combat varicella-zoster virus and prevent herpes zoster, commonly known as shingles, in adults over the age of 40.
