Active clinical trials for "Pneumococcal Infections"

This study is designed to evaluate the safety and immunogenicity of 20vPnC in healthy children 15 months through 17 years of age

The purpose of this clinical study is to evaluate the safety and immunogenicity of a 4-dose schedule (3-dose primary series followed by a toddler dose) of V114 compared with Pneumococcal 13-valent Conjugate Vaccine (PCV13). The hypotheses are that: 1) V114 is non-inferior to PCV13 for the 13 shared serotypes between V114 and PCV13 based on the response rates at 30 days following dose 3; 2) V114 is non-inferior to PCV13 for the 2 unique V114 serotypes based on the response rate of the 2 unique V114 serotypes at 30 days following dose 3; 3) V114 is non-inferior to PCV13 for the 13 shared serotypes between V114 and PCV13 based on anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) geometric mean concentrations (GMCs) at 30 days following dose 3.

20-valent Pneumococcal Conjugate Vaccine Safety and Immunogenicity Study in Healthy Japanese Infants

The purpose of this study will be to assess the safety, tolerability, and immunogenicity of 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) when given to healthy adults older than 50 years of age who haven't received 23-valent pneumococcal polysaccharide vaccine in Mexico.

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 17-39 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. All routinely recommended vaccinations on the standard vaccination schedule will continue to be offered by the subject's vaccine provider in accordance with current clinical practice. The primary outcome will be prevalence of middle ear disease 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 one or more vaccine type pneumococci at seven months of age compared to infants in each of the other two groups. A similar comparison of the proportion with middle ear disease will be undertaken between the control group and the respective intervention group.

The purpose of this study is to determine whether Zoster Vaccine Live and Pneumococcal Vaccine, polyvalent are as well tolerated and immunogenic when the vaccines are given together (in different body sites), as when they are given alone, in adults 60 years of age and older.

To test the hypothesis that immune responses to 23-valent pneumococcal polysaccharide vaccine (PPV-23) could be improved in Alaska Native elders by immune priming with 7-valent pneumococcal conjugate vaccine (PCV-7), we assessed post-vaccination immune responses among Natives aged 55 years and older who were randomized into three arms: (1) one dose of PPV-23 according to current state and ACIP recommendations; (2) one dose of PCV-7 followed two months later with a dose of PPV-23; and (3) one dose of PCV-7 followed six months later with a dose of PPV-23.

20-valent Pneumococcal Conjugate Vaccine Safety and Immunogenicity Study of a 4-Dose Series in Healthy Infants

The purpose of this study is 1) to evaluate the safety and tolerability of V114 with respect to the proportion of participants with adverse events (AEs) and 2) to evaluate the anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) at 30 days following the last dose for each vaccination group. There is no formal hypothesis testing in this study.

This Phase 1b will describe the safety and immunogenicity of 2 multivalent pneumococcal conjugate vaccine formulations in healthy Japanese adults in the United States.
