A Double-Blind Placebo-Controlled Trial of the Safety and Immunogenicity of a Seven Valent Pneumococcal Conjugate Vaccine in Presumed HIV-Infected Infants

2014-08-27 03:59:55 | BioPortfolio

Summary

To assess whether HIV-infected infants who receive a heptavalent pneumococcal conjugate vaccine have more local reactions at the site of injection and systemic reactions than placebo subjects. To assess whether this vaccine is more immunogenic than placebo following the third vaccination.

Children with HIV infection are at increased risk for invasive pneumococcal infection, particularly bacteremia. A large proportion of pneumococcal disease is caused by a limited number of serotypes. The maximum number of pneumococcal serotypes that can be included in a new conjugate vaccine is felt to be limited by the amount of carrier protein. A heptavalent pneumococcal conjugate vaccine has been developed that consists of pneumococcal capsular saccharides from serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F bound to a diphtheria toxin mutant carrier protein.

Infants are randomized to receive either heptavalent pneumococcal conjugate vaccine or placebo by intramuscular injection at study months 0, 2, and 4, and then at 15 months of age. Additionally, patients receive PNU-IMUNE 23 ( pneumococcal polyvalent vaccine ) at 24 months of age.

Medical and Biotech [MESH] Definitions

A pneumococcal vaccine which 7 pneumococcal serotypes (6B, 14, 19F, 23F, 18C, 4, 9V), each conjugated individually to the outer membrane protein complex of NEISSERIA MENINGITIDIS.

A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.

A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)

A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.

A live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had mumps or been immunized with live mumps vaccine. Children are usually immunized with measles-mumps-rubella combination vaccine.
