These studies were performed to assess the utility of the baboon as a nonhuman primate model to evaluate vaccines for use in humans. Specifically, we examined the antibody response of baboons immunized during the third trimester of pregnancy with Haemophilus influenzae type b (Hib) polyribosylribitol phosphate (PRP) conjugate and unconjugated polysaccharide vaccines. Some of the vaccinated moth...
heamophilus influenzae type-b (hib) is a gram - negative pleomorphic bacterium that causes meningitis infections in children with the age of less than 5 years particularly in two years old infants. in the present study various isolates of heamophilus influenzae from infants suspected to meningitis were collected, identified, characterized and were used throughout our experiments. different cult...
The effect of a Haemophilus influenzae type b (Hib) polyribosylribitol phosphate-tetanus toxoid conjugate vaccine (Hib/PRP-T) on oropharyngeal carriage of Hib was studied during an efficacy trial in Gambian infants. Children were vaccinated with Hib/PRP-T and diphtheria-tetanus toxoids-pertussis (DTP) or DTP alone at ages 2, 3, and 4 months. Groups of 1000 children aged 1-2 years were studied e...
We compared antibody levels following separate but simultaneous administration of diphtheria and tetanus toxoids with acellular pertussis vaccine (DTaP) containing pertussis toxoid, filamentous hemagglutinin, and pertactin (PRN); hepatitis B vaccine; and Haemophilus influenzae type b polysaccharide (polyribosylribitol phosphate; PRP) vaccine conjugated to tetanus toxoid (PRP-T) with those follo...
This study compared the levels of immunogenicity and safety of diphtheria-tetanus toxoid-five-component acellular pertussis (DTaP(5)), inactivated poliovirus (IPV), and Haemophilus influenzae type b (Hib) (DTaP(5)-IPV-Hib) and DTaP(3)-IPV/Hib vaccines for study participants 3, 5, and 12 months of age. Post-dose 3 noninferiority criteria comparing DTaP(5)-IPV-Hib to DTaP(3)-IPV/Hib using rates o...
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...
results the optimal conditions were considered to perform elisa. comparison between results obtained from optimized elisa kit and commercial elisa kit showed a good agreement. background haemophilus influenzae type b (hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. enzyme-linked immunosorbent assay (elisa) technique is the most used method to d...
In pneumococcal conjugate vaccines (PCVs), polysaccharide antigens are often conjugated to protein carriers related to other common vaccines. It is therefore important to test PCV interaction with other pediatric vaccines when administered simultaneously. We assessed the immune response to an 11-valent PCV conjugated to diphtheria and tetanus carriers (PncD/T11), administered concomitantly, but...
BACKGROUND Haemophilus influenzae type b (Hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. Enzyme-linked immunosorbent assay (ELISA) technique is the most used method to detect antibodies against H. influenzae. Available commercial ELISA kits are expensive and not always readily available, particularly for epidemiological studies. OBJECTIVES T...
Haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. The disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. Despite the availability of new and more powerful antibiotics children with Hib meningitis still suffer from high mortality or morbidity. The emergence of multir...
