Immunogenicity and Safety of Two Different Haemophilus influenzae Type b Conjugate Vaccines in Korean Infants

The incidence of invasive diseases, including meningitis caused by Haemophilus influenzae type b (Hib) was markedly decreased after routine immunization of Hib vaccine through diverse schedules in many countries. The purpose of this study was to evaluate the immunogenicity and safety of Hib conjugate vaccines in Korean children before the implementation of a national immunization program agains...

Haemophilus influenzae type B conjugate vaccines.

In summary, all of the Hib conjugate vaccines are highly immunogenic and efficacious in children older than 12-15 months of age, and HbOC, PRP-OMPC, and PRP-T are highly immunogenic and demonstrated to be efficacious in infants as young as 2 months old. HbOC, PRP-OMPC, and PRP-T have been licensed in numerous countries for infants and are recommended for infant immunization. However, perhaps th...

Safety and immunogenicity of two Haemophilus influenzae type b conjugate vaccines.

OBJECTIVES Haemophilus influenzae type b (Hib) infection remains a major public health problem in the developing world. We evaluated the safety and immunogenicity of a new PRP-CRM197 conjugate Hib vaccine (Vaxem Hib, Chiron Vaccines), compared with the HibTITER vaccine (Wyeth-Lederle Vaccines), following the World Health Organisation (WHO)'s accelerated schedule which allows 4-week intervals be...

Immunogenicity of Haemophilus influenzae Type b Conjugate Vaccines in Korean Infants: A Meta-analysis

A meta-analysis was performed on the immunogenicity of Haemophilus influenzae type b (Hib) conjugate vaccines after 2 (2 and 4 months) and 3 doses (2, 4, and 6 months) in Korean infants. A database search of MEDLINE, KoreaMed, and Korean Medical Database was done. The primary outcome measure was the proportion of infants with anti-polyribosylribitol phosphate (PRP) concentrations > or =1.0 micr...
