Vaccines are class of drugs designed to prevent the user from contracting a specific disease. A specific Vaccine works for a specific disease, enhancing the patients' immune system to resist the disease. Vaccines must be re-administered periodically usually once per year, through the protective effects of some vaccines last longer.
At TL–10, Vaccines can be tuned to protect against several similar diseases, and the protections last for 10 years. These enhanced vaccines are Cr20 per dose.
