Porter W. Anderson Jr. and David Hamilton Smith were two of the four scientists principally responsible for developing the Haemophilus influenzae type b (Hib) vaccine. Their work transformed Hib from a leading cause of childhood meningitis into a largely vaccine-preventable disease

Their research began in the late 1960s at Boston Children's Hospital, where they investigated why Hib caused severe infections in infants and young children. Anderson, a microbiologist, and Smith, a pediatric infectious disease specialist, identified the bacterium's capsular polysaccharide—polyribosylribitol phosphate (PRP)—as the critical antigen capable of inducing protective immunity.
