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.
The goal of this interventional clinical trial is to investigate the impact of medicine and pharmacy-led education on patient acceptance rates of Prevnar 20 pneumonia vaccination in patients eligible to receive the vaccine. The education intervention and subsequent option to get the vaccine will be done while the patient is admitted to inpatient care, prior to discharge. The main questions the study aims to answer are: - Will supplemental education about the Prevnar 20 Pneumococcal vaccine influence patient acceptance rates when given a decision to receive it? - Is there any other statistically relevant qualitative reasoning behind the patient's final decision for accepting or refusing the vaccine?
The goal of this experimental pneumococcal carriage study is to to characterise rates and determinants of experimental pneumococcal carriage in PLHIV. The main questions it aims to answer are: - can PLHIV be experimentally inoculated with pneumococcus in a safe manner? - what are the immunological determinants of pneumococcal carriage in PLHIV compared to HIV-negative participants? - how do the pneumococcal carriage dynamics differ between PLHIV and HIV-negative participants? Participants will be inoculated intranasally with a controlled concentration of pneumococcus after which they will be monitored for 21 days during which nasal and systemic immune dynamics and pneumococcal carriage dynamics will be evaluated. At the end of the study any participants exhibiting carriage will have the pneumococcus cleared with antibiotics.
The current study provides data necessary to evaluate the safety and immunogenicity of Serum Institute of India's PNEUMOSIL® [Pneumococcal Polysaccharide Conjugate Vaccine Adsorbed (10-Valent)] in Healthy Vietnamese Infants and Toddlers, 6 weeks to 24 months of age. This is an open label, prospective, bridging study.
This household-based prospective cohort study aims to stablish the household transmission of Respiratory syncytial virus and S. pneumoniae especially in the elderly and infants/children as well as inter-relationship between S. pneumoniae and Respiratory syncytial virus.
The purpose of this study is to evaluate Immunogenicity and safety of 15-Valent Pneumococcal Conjugate Vaccine in healthy volunteers aged 2 and 3 months.
