OBJECTIVE To evaluate the immunogenicity of a combined DTPa-HB vaccine co-administered with Haemophilus influenzae type b conjugate vaccine (PRP-T) in Brazilian infants. MATERIAL AND METHODS A prospective and open clinical study, in which 110 infants were immunized with a three-dose primary vaccination regime at two, four and six months of age and with a single booster vaccination. Blood samp...

SUMMARY Thirteen patients with Haemophilus influenzae type b pneumonia are reported to emphasise the clinical, radiographic, and therapeutic aspects of this illness. All but one patient was tnder 21 years of age. The presenting complaint was a variable duration of upper respiratory infection and fever in most cases. One-third of patients had radiographic evidence of pleural involvement ; one-th...

The age-related acquisition of serum anticapsular and bactericidal antibodies to Haemophilus influenzae type b observed in rats was similar to that of humans. The antigenic source for this "natural" immunity was not identified, since neither pharyngeal infection with H. influenzae b nor enteric colonization by cross-reacting bacteria was detected. Infant rats surviving H. influenzae b bacteremi...

Thirteen patients with Haemophilus influenzae type b pneumonia are reported to emphasise the clinical, radiographic, and therapeutic aspects of this illness. All but one patient was under 2 1/2 years of age. The presenting complaint was a variable duration of upper respiratory infection and fever in most cases. One-third of patients had radiographic evidence of pleural involvement; one-third sh...

An international collaboration was established in 1996 to monitor the impact of routine Haemophilus influenzae type b (Hib) vaccination on invasive H. influenzae disease; 14 countries routinely serotype all clinical isolates. Of the 10,081 invasive H. influenzae infections reported during 1996-2006, 4,466 (44%, incidence 0.28 infections/100,000 population) were due to noncapsulated H. influenza...

Before the introduction of effective vaccines, H. influenzae, type b (Hib) was the leading cause of bacterial meningitis and other invasive bacterial disease among children less than 5 years of age. In 1997, ten confirmed cases of invasive disease caused by the serotype b strain of H. influenzae were reported. This is the first year that the number of cases increased since the conjugate vaccine...

In the period November 1967 to September 1968 Haemophilus influenzae type b was isolated from the blood of 11 young children. Only three of these presented with meningitis; others had septic arthritis, oesteomyelitis, subcutaneous abscesses, cellulitis, respiratory infections, and undifferentiated pyrexia. During the preceding five years H. influenzae type b was isolated from the blood cultures...
