OBJECTIVE New vaccines that offer protection against otitis media caused by nontypeable Haemophilus influenzae and by Moraxella catarrhalis are under development. However, the potential health benefits and economic effects of such candidate vaccines have not been systematically assessed. METHODS We created a computerized model to compare the projected benefits and costs of (1) the currently a...
AIMS The purpose of this study was to determine the prevalence of nasopharyngeal carriage of Streptococcus pneumoniae in healthy children aged 0-6 years who were vaccinated with pneumococcal conjugate vaccine. METHODS The cross-sectional study was conducted on 150 healthy Turkish children aged between 1 month and 6 years of age. Serotyping was performed and risk factors of carriage were evalu...
The vaccine developed for pneumococcal diseases is a heptavalent conjugate vaccine (PCV 7). This particular vaccine consists of capsular polysaccharides originated from seven different Streptococcus pneumoniae species along with the protein diphtheria crm197 as conjugate antigens. In a month time after inoculation in children this vaccine is able to increase the IgG level sufficiently to combat...
Three years after a 7-valent pneumococcal conjugate vaccine was replaced by a 10-valent pneumococcal conjugate vaccine in the Netherlands, we observed a decrease in incidence of invasive pneumococcal disease caused by Streptococcus pneumoniae serotypes 1, 5, and 7F. Our data do not support or exclude cross-protection against serotype 19A.
BACKGROUND Pneumonia remains the leading cause of death in young children. The poor specificity of chest radiographs (CXRs) to diagnose pneumococcal pneumonia may underestimate the efficacy of pneumococcal conjugate vaccine in preventing pneumococcal pneumonia. METHODS AND FINDINGS The efficacy of nine-valent pneumococcal conjugate vaccine among children not infected with HIV (21%; 95% confid...
The objective of this study was to evaluate the projected health benefits, costs, and cost-effectiveness of pneumococcal conjugate vaccination for infants and children aged <5 years in Canada. A health state model incorporating incidence, vaccine efficacy, costs, and transitional probabilities for the health states (well, meningitis, bacteremia, otitis media, pneumonia, and death) was construct...
OBJECTIVES To evaluate the impact of heptavalent pneumococcal conjugate vaccine in invasive pneumococcal diseases in the United States, and to analyze the potential impact of this vaccine in Brazil. SOURCES OF DATA MEDLINE, LILACS, Cochrane Database Reviews, as well as the websites of the Centers for Disease Control and Prevention (CDC), Brazilian Ministry of Health and Centro de Vigilância E...
Children 12-18 months old were randomized to receive one dose of a conjugate heptavalent pneumococcal vaccine, two doses of the same vaccine, or one dose of a 23-valent native polysaccharide vaccine. Before immunization, pneumococci included in the conjugate vaccine were isolated from 24% of the children, and an antibiotic-resistant pneumococcus was isolated from 22% of the children. The vaccin...
Pneumococcal polysaccharide vaccine has been licensed for use in the United States for >30 years, and two-thirds of the elderly population in the United States have received this vaccine. Observational studies have demonstrated that pneumococcal polysaccharide vaccine reduces the risk of invasive pneumococcal disease in immunocompetent elderly individuals, but neither observational studies nor ...
BACKGROUND Serogroup distribution of sterile site pneumococcal isolates varies between developing and developed countries as well as between different geographical regions. The potential efficacy of any pneumococcal vaccine depends on the degree of representation of the prevalent serogroups in the vaccine. We conducted this study to determine the prevalent pneumococcal serogroups causing invasi...
