Background: Induction of immunologic memory was assessed following primary vaccination with 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV).
Methods: Infants were randomized (1:1) to receive 3 doses of PHiD-CV or 7vCRM (7-valent CRM197-conjugated pneumococcal conjugate vaccine [PCV]) at 2, 3, and 4 months of age followed by 23-valent pneumococcal polysaccharide vaccine (23vPS) booster dose at 11 to 14 months of age. Pneumococcal geometric mean antibody concentrations (GMCs) and opsonophagocytic activity (OPA) geometric mean titers were measured.
Background: This randomized single-blind study in Korea evaluated noninferiority of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) versus the 7-valent pneumococcal conjugate vaccine (7vCRM) when both were coadministered with H. influenzae type b (Hib) conjugate vaccine, as opposed to coadministration with diphtheria-tetanus-acellular pertussis-based combination vaccines in previous studies.
Methods: Infants received 3 primary doses at 2, 4, and 6 months and a booster dose at 12 to 18 months of PHiD-CV (N = 374) or 7vCRM (N = 129), both coadministered with Hib vaccine.
Background: We evaluated catch-up vaccination schedules with 10-valent pneumococcal nontypeable Haemophilus influenzae Protein D Conjugate Vaccine (PHiD-CV).
Methods: In this open, controlled study, children stratified into 4 age groups (N = 150 each) were vaccinated with PHiD-CV: (a) <6 months reference group: 3 primary doses with booster at 12 to 15 months, (b) 7 to 11 months: 2 doses and booster at 12 to 15 months, (c) 12 to 23 months: 2 doses, and (d) 2 to 5 years: 1 dose. Serotype-specific pneumococcal responses were measured by 22F-inhibition enzyme-linked immunosorbent assay (ELISA) and opsonophagocytic activity (OPA) assay.
