Let me give you a quick vocabulary lesson. GLP, good laboratory practice, is usually applicable to the very earliest stages of developing a vaccine. GMP, good manufacturing practice, is what you have do when making a product that will go into a person either at the clinical level or the commercial level. The other one we're probably going to hear about is GCP, good clinical practice, to make sure the clinical trial follows all of the regulations.
