Active clinical trials for "Pneumococcal Infections"

Serum 89 SF is a supply of serum that was collected from people who were vaccinated with the pneumococcal vaccine in the late 1980s. The supply of this serum is running low. The purpose of this study is to give the pneumococcal vaccine to healthy volunteers and take serum blood samples in order to increase the reference serum supply. Study participants will include 250 healthy men and women, ages 18-45. Study procedures will include a physical exam, interviews, blood samples and blood testing. All volunteers will receive the pneumococcal vaccine in the deltoid muscle of the arm. Participants will be involved in the study for approximately 17 weeks.

The purpose of this study is to determine if Pneumovax™ 23 (V110) is safe and immunogenic in participants from the Russian population who are 50 years of age and older or 2 to 49 years of age and at increased risk for pneumococcal disease

The purpose of this study is to determine if revaccination with pneumococcal vaccine (PNEUMOVAX™ 23, V110) is well tolerated and produces an immune response in older Japanese adults. The primary hypothesis being tested is that the geometric mean concentration of antibodies to pneumococcal polysaccharide serotypes 3, 6B, and 23F at 4 weeks after revaccination will be superior to that before revaccination in Japanese adults who received a primary vaccination at least 5 years before revaccination.

The purpose of the study is to evaluate the immune responses of UK infants after one or two doses of pneumococcal conjugate vaccine or one or two doses of three different types of meningococcal conjugate vaccine given at either two and three or two and four months of age.

Infection with Streptococcus pneumoniae (the pneumococcus) is the leading cause of pneumonia, bacterial meningitis and bacteraemia worldwide in the very young and the elderly. Although pneumococcal vaccines exist, they do not provide complete protection and new strategies to combat this pathogen are urgently needed. Asymptomatic infection of S. pneumoniae in the human nasopharynx precedes the development of pneumococcal disease. Previously, an Experimental Human Pneumococcal Carriage (EHPC) model has been developed at the Liverpool School of Tropical Medicine (LSTM). The current study entails to establish this model in healthy adults living in the Netherlands using the inoculation dose currently used at LSTM. Healthy adult participants (M/F) will be inoculated intranasally with strain BHN418, a penicillin sensitive serotype 6B strain of S. pneumoniae that was previously isolated from a healthy carrier. Following inoculation, participants will be monitored and blood and nasal samples will be collected over a period of 28 ± 3 days. Participants will receive a course of amoxicillin to eradicate infection on or shortly after the last visit at day 28 ± 3, unless S. pneumoniae is not detected on both day 14 and 28 ± 3 post-inoculation.

Prevenar 13 is safe for administration to Filipinos.

Premature infants are at a high risk for pneumonia. The PCV-7 vaccine effectively prevents the invasive disease from Streptococcus pneumoniae in full-term infants, but was not thoroughly studied in premature infants. This study evaluated the effectiveness and safety of the vaccine given in routine practice to very low birth weight infants, looking at blood antibody levels 4-6 weeks after the final vaccine dose, and adverse events, survival, infections, and neurodevelopmental outcomes at 18-22 months corrected age.

Pneumococcus is a major cause of morbidity and mortality. In 2000, a pneumococcal conjugate vaccine (PCV) was licensed for use in children and is now part of the routine childhood vaccine schedule. PCV is known to reduce invasive disease and protect against nasopharyngeal (NP) acquisition of vaccine serotype pneumococci; it also results in an increased risk of nonvaccine serotype carriage. This study proposes to assess the longterm impact of vaccine on NP carriage in a setting where there is intense antibody pressure on the ecology of the pneumococcus. A cross sectional study of pneumococcal NP colonization among American Indian children will be combined with surveillance for invasive disease in the same population. The purpose is to determine the impact of community wide PCV use on NP colonization and the relationship with invasive disease. This longterm safety issue needs to be assessed to fully evaluate the impact of vaccine on NP ecology and invasive disease.

The purpose of this study is to identify the following problems and questions with respect to the safety of Pneumococcal 7-Valent Conjugate Vaccine (Diphtheria CRM 197 Protein), Prevenar, during the post-marketing period in Korea, as required by Korea Food and Drug Administration (KFDA) regulations. Adverse reactions (especially serious adverse reactions) Incidences of adverse reactions under routine vaccine use Factors that may affect the safety of the vaccine

The purpose of this study is to estimate the local and systemic tolerability of Prevenar in children ages 2 to 5 years old in usual care settings.
