View clinical trials related to Pneumococcal Infections.
Filter by:Respiratory tract infections are among the leading causes of death worldwide and many of these infections are preventable through vaccination. One of the most important bacteria from an etiological and mortality point of view regarding respiratory and systemic infections is the gram-positive Streptococcus pneumoniae. Four types of vaccines are currently available for this pathogen: three pneumococcal conjugate vaccines (PCV13, PCV15, and PCV20) and one polysaccharide vaccine (PPSV23). In Italy, people over 65 years of age and people suffering from chronic pathologies with effects on the immune system would be advised to be vaccinated with the pneumococcal conjugate vaccine and with the polysaccharide vaccine as a second dose. However, there are no data available in Italy on vaccination coverage in these population categories and above all the vaccination rates in patients who have a history of an episode of invasive pneumococcal infection are not known. The aim of the study is to measure how many patients are vaccinated for S. pneumoniae after hospitalization for a systemic pneumococcal infection in order to understand patients' awareness of preventing this infection after receiving a first diagnosis.
A phase 1b clinical trial of 13-valent Pneumococcal Polysaccharide Conjugate Vaccine (PCV13) developed by Sinovac Life Science Co., Ltd will be conducted in children aged 2 months (42-89 days) and 2 to 5 years. The objective of the study is to evaluate the safety and immunogenicity of Sinovac PCV13. The trial is a randomized, double blinded, positive controlled study.
The purpose of this study is to learn about the safety and immune effects of a pneumococcal vaccine in adults. This vaccine can possibly provide protection against further pneumococcal disease. This study will happen in in 2 stages: Stage 1 is seeking participants who are between 18 years to 49 years of age. The participants will receive 1 of 2 pneumococcal vaccine candidates (different formulations) or 20vPnC (Prevnar 20) as a single shot given into the upper arm muscle. Stage 2 will begin after participants have completed Stage 1, and a pneumococcal vaccine candidate has been decided. Stage 2 is seeking participants who are adults 50 years of age and older. The participants will receive the chosen pneumococcal vaccine candidate from Stage 1 or 20vPnC (Prevnar 20). The vaccines will be given as a single shot into the upper arm muscle. Participants will take part in this study for about 6 months for Stage 1 and 12 months for Stage 2. During this time participants will have from 2 to 4 clinic visits and 1 phone visit. At these clinic visits, participants will be asked if any side effects were experienced. The participants will also have to give blood samples during these clinic visits.
The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of V116 compared to PPSV23 in children 2 through 17 years of age. Researchers want to learn if V116 is as good as, or is better than the PPSV23 vaccine in terms of the antibody immune response. V116 and PPSV23 will be studied in children and teenagers who have a higher risk of getting invasive pneumococcal disease (IPD).
This study is a randomized, blinded, parallel controlled phase 3 clinical trial to evaluate the immunogenicity and safety of the 23-valent pneumococcal polysaccharide vaccine in healthy people aged 2 years and above.
This is a randomized, double-blind, placebo-parallel intervention clinical study that will include approximately 38 healthy subjects based on inclusion and exclusion criteria. Subjects will be assigned to one of four different dosage cohorts. Subjects in each cohort will randomly be given experimental drug or a placebo.
A 6 and 12 month safety and immunogenicity study of participants in study GPNV-001, a novel whole-cell pneumococcal vaccine.
Hypothesis of non-inferiority test for seropositive rate and GMC in each serotype
The goal of this cluster-randomized trial is to study the effect of Audit and Feedback loops on pneumococcal vaccination coverage rate in adults at risk in general practice. The main questions it aims to answer are: - To assess the effect of "clinical AUDIT and feedback" loops on the pneumococcal vaccination coverage rate in adults at risk in general practice. - To explore whether the increase in vaccination coverage rate after implementation of Audit and Feedback loops is different in specific subgroups (risk groups, male/female, age, smoking status). Every general practice center assigned to the control or intervention group will have access to a clinical AUDIT to identify patients that may benefit from a pneumococcal vaccination. The general practice centers in the intervention group will also receive an individualized extended electronic feedback report, with multiple components like benchmarked performances and action plans, at baseline and each 2 months from baseline onwards.
The purpose of this study is to learn about the safety and immune response of 20vPnC in adults in India. This study is seeking participants who: - are generally healthy adults of 18 years or older. - have not received pneumococcal vaccine. The study will have 2 groups based on age. One group will have particpants between 18 to 49 years of age. The other group will have participants of 50 years or older. Participants will take part in the study for about one month which includes two visits to the study clinic. Participants will receive a single dose of study vaccine (20vPnC) into the arm at visit 1 and will come to study site for a follow-up visit after about a month. The study team will ask questions about the participant's health and blood samples will be taken in a subset of participants during the visits.
