Active clinical trials for "Pneumococcal Infections"

The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of GSK Biologicals' 10Pn-PD-DiT vaccine in children aged between 2 and 17 years of age having asplenia, splenic dysfunction or complement deficiencies. In addition, this study will include an age-matched control group of healthy children aged 24-59 months in order to descriptively compare the immunogenicity of 10Pn-PD-DiT vaccine in the at-risk population to that of the general, healthy population one month after each pneumococcal vaccination.

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

This study is designed to explore the safety and tolerability of an investigational pneumococcal vaccine through a step-down enrollment. Primary Objective: To evaluate the safety and tolerability of an investigational pneumococcal vaccine. Secondary Objective: To evaluate the immunogenicity of an investigational pneumococcal vaccine.

The purpose of this study is: To assess whether there are differences in antibody persistence eight months post primary (pre-booster) or in responses to the booster with regard to the Meningococcal C Conjugate (MCC) vaccine given in infancy. To examine levels of diphtheria and tetanus antibody pre- and post-booster, with regard to the carrier proteins contained in the conjugate vaccines.

To evaluate the safety of 13-valent pneumococcal conjugate vaccine (13vPnC) in elderly subjects who were vaccinated with one or more doses of 23-valent pneumococcal polysaccharide vaccine (23vPS) at least 3 years before study enrollment.

Two( 2) or three (3) instead of four vaccinations before the age of 6 months with pneumococcal conjugate vaccine are presumed to protect children against invasive pneumococcal disease like meningitis, at least on the short term till 18-24 months of age. The current hypothesis in this study is 2 or 3 vaccinations will protect against IPD but will not alter pneumococcal nasopharyngeal carriage in infants, and consequently not change pneumococcal transmission and induce no herd-immunity. Furthermore, antibody development and memory may benefit from carriage of vaccine type S. pneumoniae

The purpose of this study is to evaluate the safety and immunogenicity of the 13-valent pneumococcal conjugate vaccine (13vPnC) in healthy infants. This is the first study with this vaccine in infants.

Streptococcus pneumoniae is a major cause of morbidity and mortality in children worldwide, resulting in up to 1 million pediatric deaths every year.Since the licensure of PCV7 and PCV13,the reported overall decline in invasive pneumococcal disease in hospitalized children younger than 5 years several years is approximately 60% in Western countries.This is a single center,blind, randomized, positive-controlled clinical trial.The purpose of this study is to preliminary evaluate the safety of PCV13i vaccine in subjects at age of 7 months and above,and to investigate the safety and immunogenicity of PCV13i vaccine at age of 2 and 3 months,compared to PCV13.

Study of the safety and immunogenicity of 20vPnC and a booster dose of BNT162b2 administered at the same visit or each vaccine given alone

This study is designed to evaluate the safety and tolerability of 20vPnC in healthy infants.
