Research Focus
Vaccine Development and Evaluation
Research Overview
Dr. Pichichero was a member of the discovery team at the University of Rochester that invented, tested and licensed a Haemophilus influenzae b (Hib) conjugate vaccine (HibTITER®) now universally given to children in the U.S. This “conjugate” vaccine technology was used in the subsequent development of another universally-given vaccine- the pnuemococcal conjugate vaccine (Prevnar®). Dr. Pichichero has played a role in the clinical and/or translational research leading to licensure of many vaccines including acellular pertussis vaccines (DTaP), combination vaccines (DTaP-Hib-polio and DTaP-Hepatitis B-polio), meningococcal conjugate vaccine, Rotavirus vaccine, Human papillomavirus vaccine, adolescent Tdap vaccines and others.
Now Dr. Pichichero is leading a research team of scientists at the UR working toward the development of a multi-component vaccine to prevent ear, sinus and lung infections caused by pneumococci and non-typeable H. influenzae. The approach is multi-focused including:

  1. The study of natural infection and asymptomatic colonization with these bacteria in children.
  2. Evaluation of serum and mucosal antibody; generation of B memory cell and T cell responses to disease, colonization and vaccine candidates.
  3. Molecular epidemiology.
  4. Vaccine antigen discovery.
The Pichichero lab also collaborates with vaccine companies, international scientists, federally funded investigators, the NIH, FDA, CDC and WHO to characterize immunogenicity and efficacy of vaccines.
