Active clinical trials for "Pneumococcal Infections"

Streptococcus pneumoniae is a major cause of pneumonia, sepsis, bacteremia, and pneumococcal meningitis among infants and children worldwide. The 7-valent conjugate pneumococcal vaccine (Prevenar) has been introduced in the Greek Market in 2004. Additionally, as of 2006 Prevenar has been included in the Greek National Immunization Program. The effect of the mass vaccination on the incidence of pneumococcal serotypes involved in the occurring invasive pneumococcal disease, is an important factor to consider for the introduction of the 13-valent pneumococcal conjugate vaccine.

The purpose of this study is to assess the indirect effects of a pneumococcal conjugate vaccine administered to infants on vaccinees' elder non-vaccinated siblings aged 3 to 7 years.

This is an observational study to determine the reactogenicity and immunogenicity of pneumococcal conjugate vaccine in non-pregnant women of reproductive age in Papua New Guinea.

The purpose of the study is to expand the understanding of the safety profile of 13vPnC in routine use following licensure and introduction of the vaccine.

This postmarketing surveillance study will evaluate the safety profile of Prevenar in Indian children. Prevenar is indicated for active immunization of infants and children from 6 weeks of age through 9 years of age against invasive disease (including meningitis, bacteraemic pneumonia, bacteraemia, sepsis) caused by Streptococcus pneumoniae serotypes 4, 6B, 9V, 14, 18C, 19F and 23F. Prevenar has been marketed in India since June 2006. The Board of Health in India has given restricted permission to import and market Prevenar. The present study is a post-approval regulatory commitment to the Board of Health in India. This is an observational study and the protocol for the study has been approved by the Board of Health.

PneuMum is a randomised controlled trial that aims to find out if pneumococcal vaccination for Australian Indigenous mothers, in the last few months of pregnancy or at delivery, can prevent ear disease in infants. Mothers will receive the 23 valent pneumococcal polysaccharide vaccine (23vPPV) either: a) during the third trimester of pregnancy; b) soon after child birth; or c) seven months after child birth (control group). The adult diphtheria, tetanus and acellular pertussis vaccine (dTPa) will be used as the control vaccine for the birth dose. The study aims to recruit 210 Indigenous women aged 18-39 years who have an uncomplicated pregnancy. Following recruitment, subjects will be randomly assigned to one of the three groups. Each mother and infant will be followed from pregnancy until the baby is seven months of age. Children will receive all of their routinely recommended vaccinations in accordance with the standard vaccination schedule. The primary outcome will be prevalence of ear infection at seven months of age, defined as middle ear effusion or tympanic membrane perforation or acute otitis media. Pneumatic otoscopy, video-otoscopy and tympanometry will be used in the ear examinations. The primary analyses will be a direct comparison of the proportion of infants in the control group who have nasopharyngeal carriage of vaccine type pneumococci at seven months of age compared to infants in each of the other two groups and a similar comparison of the proportion with middle ear disease.

phase-1 study pneumococcal conjugate vaccine study in healthy adults

This study evaluated the change in nasopharyngeal carriage (NPC) of Streptococcus pneumoniae (SPn), hypothesizing that it would be reduced post-vaccination with Streptococcus pneumoniae whole cell vaccine with aluminum hydroxide adjuvant (PATH-wSP) and that PATH-wSP would remain safe and well-tolerated over the course of the study.

The aim of this study is to evaluate the postlicensure effectiveness of Prevnar in the prevention of IPD in the Spanish paediatric population (children younger than 5 years)

Infection by Streptococcal pneumoniae is a common invasive bacterial infection in HIV infected children. The purpose of this study is to determine the safety of and immune response to a pneumococcal polysaccharide-protein conjugate vaccine (PncCV) in HIV infected and uninfected children. The study will also determine the safety of and immune response to Haemophilus influenzae vaccine (HibCV) in these children. Recruitment for this study will occur at two hospitals in South Africa, and all HIV infected infants participating in this study must also be coenrolled in the CIPRA SA-Project 2 study.
