Active clinical trials for "Pneumonia, Pneumococcal"

The aim of this study is to assess the effectiveness of GSK Biologicals' pneumococcal conjugate vaccine (GSK1024850A), administered according to different vaccination schedules, against invasive disease caused by S. pneumoniae or H. influenzae as well as vaccine impact on the occurrence of hospital-diagnosed pneumonia cases, tympanostomy tube placement and outpatient antimicrobial prescriptions. This study will also explore vaccine impact on occurrence of respiratory tract infections (RTIs), including acute otitis media (AOM) in a subset of children in Turku area.

Streptococcus pneumoniae are bacteria which normally live in the upper respiratory tract of humans. However, these bacteria can also cause severe infectious diseases such as pneumonia, septicemia and meningitis. Elderly subjects are especially vulnerable to these infections, and the diseases can result in death. The currently available licensed Streptococcus pneumoniae vaccine is recommended for prevention of pneumococcal diseases in individuals over the age of 65. However, the antibody level elicited by this vaccine, is not always satisfactory in elderly people. To overcome the problem, GlaxoSmithKline Biologicals is currently developing candidate vaccines that are hoped to work better than the currently available vaccines. As a first step in this development, the present study is being conducted in order to evaluate the immune response to the currently marketed vaccine.

The primary objectives of this study are to evaluate the immunogenicity (antibody response) and safety and tolerability of a 2-dose primary series and booster dose (2+1 schedule) of Pneumosil co-administered with routine pediatric vaccines in healthy infants in The Gambia.

To obtain first-in-human data on a new candidate vaccine against Streptococcus pneumoniae in healthy adult and elderly volunteers. The study aims to assess the safety and immunogenicity of a bioconjugate investigational vaccine compared to the control group (Pneumovax23).

GEN-004 is a combination of 3 conserved proteins from Streptococcus pneumoniae. This is a randomized, double-blind, placebo-controlled, dose escalation study. Eligible subjects (male and non-pregnant female) will be assigned sequentially to 1 of 3 dose cohorts and randomized in a 3:1:1 ratio to receive GEN-004 with adjuvant, GEN-004 without adjuvant, or placebo, respectively. Each subject will receive up to 3 doses at 4 week intervals. Subjects will be followed for safety, tolerability, and immunogenicity for 12 months after their last dose.

The purpose of this study is to investigate and valuate the immunogenicity and safety of the 13-valent pneumococcal polysaccharide conjugate vaccine in 2-71 months old healthy infants and toddlers (the youngest could be 6 weeks old)

This study was designed to evaluate the safety, tolerability, and immunogenicity of three doses of an investigational pneumococcal vaccine in healthy adult volunteers. Primary Objective: To evaluate the safety and tolerability of an investigational Pneumococcal vaccine.

The purpose of the study is to evaluate the safety and reactogenicity of Synflorix™ (GSK 1024850A) given as a 3-dose primary immunization course when co-administered with Infanrix hexa™ vaccine at 2, 3 and 4 months of age in infants in Vietnam.

This protocol posting deals with objectives & outcome measures of the extension phase up to 48-50 months post booster vaccination, to assess long-term antibody persistence in children at around 30, 42 and 66 months of age, who received previously 4 doses of pneumococcal conjugate vaccine. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = 00307554). This Protocol posting has been updated in order to comply with the FDA AA (Sep 2007).

This household-based prospective cohort study aims to stablish the household transmission of Respiratory syncytial virus and S. pneumoniae especially in the elderly and infants/children as well as inter-relationship between S. pneumoniae and Respiratory syncytial virus.
