Phase I (1982-1990):  Investigation of outbreaks of vaccine-preventable diseases (e.g., diphtheria, pertussis, polio, measles) in US and abroad.  Established protective correlate of immunity for measles.

Phase II (1988-2005): Modernized vaccine safety infrastructure in the U.S. and elsewhere (e.g., Vaccine Adverse Event Reporting System [VAERS], Vaccine Safety Datalink [VSD] Project, Clinical Immunization Safety Assessment [CISA] Centers, the Brighton Collaboration, and the Safe Injection Global Network [SIGN]) and using it for rigorous studies of vaccine safety (e.g., rotavirus vaccine and intussusception, thimerosal/MMR and autism).

Phase III (2005 +) : Preventing medical transmission of HIV via unsafe injections or blood transfusions and develop new safe and effective HIV prevention biomedical interventions  via clinical trials in settings with high HIV incidence.
