Streptococcal pneumonia

This early-stage trial tested a new 23-valent pneumococcal polysaccharide vaccine in 144 healthy people aged 2 and older. Participants received one dose of either the experimental or a control vaccine. The study checked for side effects and measured immune response through blood …

This completed study looked at how effective the Prevnar 13 (PCV13) vaccine is at preventing pneumonia and related infections in adults with HIV. Researchers analyzed health records of over 350,000 people with HIV to compare those who got the vaccine with those who did not. The g…

This study tested a new pneumococcal vaccine (V116) given at the same time as the seasonal flu shot in 1,080 adults aged 50 and older. The goal was to see if giving both vaccines together is safe and produces a strong immune response. Results help determine whether combining thes…

This study tested a new vaccine called AFX3772 in healthy infants about 2 months old. The goal was to see if it is safe and triggers a strong immune response against pneumococcal bacteria, which can cause pneumonia and other serious infections. Researchers compared AFX3772 with e…

This study in Blantyre, Malawi, compares two schedules of the pneumococcal conjugate vaccine (PCV13): the current 3-dose schedule without a booster (3+0) versus a 2-dose schedule with a booster at 9 months (2+1). The goal is to see if the booster reduces carriage of vaccine-type …

This study investigates how a specific strain of pneumococcus bacteria (serotype 3) colonizes the nose of healthy adults. Researchers will give volunteers nose drops containing the bacteria to see what dose leads to colonization and how long the bacteria stay before the immune sy…

This study looks at how common pneumococcus bacteria are in the noses and throats of healthy Vietnamese children aged 6 months to 5 years. Researchers will take a simple swab and interview parents about factors like vaccination history, antibiotic use, and living environment. The…

This study looked at 688 adults hospitalized with pneumonia in 11 hospitals in Colombia to find out how many cases were caused by pneumococcal bacteria. Researchers also identified which bacterial strains were most common and whether current vaccines cover them. The goal is to he…
