Methods are provided for treating a vaccine containing infectious particles which may be viral, bacterial, and/or cellular in nature. Preferred methods include the steps of adding an effective, non-toxic amount of an endogenous photosensitizer to the fluid and exposing the fluid to photoradiation sufficient to inactivate the infectious particles but not enough to damage the antigenic characteristics of the infectious particles.
