-
Nasal immune responses in older adults with pneumococcal or viral respiratory infections
This project will test whether nasal immune responses differ in adults 60–85 with pneumococcal pneumonia, older adults carrying pneumococcus without symptoms, and those with flu or RSV.
-
PCV-20 vaccination for adults during a short febrile illness
This test sees if giving the PCV-20 pneumococcal vaccine to adults hospitalized with a short, non-severe fever produces the same immune response and safety as giving it after the fever has resolved.
-
Evaluating a new pneumococcal vaccine in infants
This study is testing a new pneumococcal vaccine for infants to see if it is safe and works as well as an existing vaccine when given with other routine shots.
-
Vaccination safety and immune response in adults with HIV
This study is testing how safe and effective meningococcal and pneumococcal vaccines are for adults with HIV who are on treatment.
-
Evaluating the impact of pneumococcal vaccination on invasive infections in children
This study is trying to see how well the pneumococcal vaccines are working to protect children from serious infections caused by pneumococcus.
