Filter by:Bacterial meningitis is a major cause of morbidity and mortality in childhood. Antibiotic treatment recommendations are based on epidemiological and susceptibility data. The epidemiology of bacterialméningitis has changed in recent years, mainly owing to widespread use of different conjugate vaccines. The aim of this prospective national survey is to describe epidemiology of bacteria implicated in bacterial meningitis in children.
After 7 then 13 valent pneumococcal conjugate vaccine implementation in France in children, we will evaluate the impact of this vaccination on invasive pneumococcal disease (IPD). We will describe the clinical characteristics of IPD, pneumococcus serotyping, underlying conditions and vaccination status.
The investigators intend to investigate the carriage of pneumococci and other respiratory microbes since the introduction of pneumococcal conjugate vaccines (Prevenar 7 and Prevenar 13). The principal aim is to gain a collection of samples that can be used to help investigate any changes that might occur in the epidemiology of microbes that are carried in the upper respiratory tract and which may cause respiratory disease, sepsis or meningitis after the introduction of Prevenar. Nasopharyngeal and nasal swabs will be taken from up to 2,000 children aged 4 years and under in each year of the study. Swabs will be processed using traditional microbiology and molecular diagnostic techniques and isolated microbes such as S. pneumoniae further characterised using molecular methods. The investigators will also ask parents to complete a short questionnaire requesting: basic demographic data; vaccine history; recent illness; overseas travel and antibiotic usage. The study will contribute to the success of the introduction of pneumococcal conjugate vaccines and will play a central role in maintaining confidence. The study will also help provide information for future vaccine policy as further vaccines are developed against microbes which cause respiratory disease, sepsis and meningitis.
The purpose of this study is to assess the safety and immunogenicity of 13-valent Pneumococcal conjugate vaccine in Chinese infant and young children.
The purpose of this study is to evaluate the safety, tolerability and immunogenicity of a single dose of 13-valent pneumococcal conjugate vaccine compared to a single dose of 23-valent pneumococcal polysaccharide vaccine in Japanese adults aged 65 years old and older.
This study is to evaluate the safety, tolerability and immunogenicity of 13-valent pneumococcal Conjugate Vaccine in children with Sickle Cell Disease who have already been vaccinated with 23-valent polysaccharide vaccine. The study will measure the amount of antibodies (the proteins that fight off germs) produced by children with Sickle Cell Disease after they have been given the 13-valent pneumococcal vaccine between 6 and less than 18 years of age. They will be given the vaccination twice, each vaccination separated by approximately 6 months.
The purpose of this study is to assess the "late" immune response to further doses of pneumococcal conjugate vaccine more than 10 years after primary immunization with Prevnar (7vPnC) in infancy, as compared with individuals who did not receive Prevnar in infancy (the Prevnar naive cohort which received MnCC). The study will take place at a single study center. Study participants must have participated previously in a specific Wyeth Prevnar study (Study D118-P8) and must still be enrolled in the Northern California Kaiser Permanente (NCKP) health plan.
The purpose of this study is to assess the safety, tolerability and immunogenicity of a 13-valent pneumococcal conjugate vaccine (13vPnC), relative to a 7-valent pneumococcal conjugate vaccine (7vPnC) when given concomitantly with routine vaccines in Taiwan.
