Volunteer for NIAID-funded clinical studies related to pneumococcal pneumonia on ClinicalTrials.gov.
Pneumococcus is spread through contact with people who are ill or who carry the bacteria in their throat. You can get pneumococcal pneumonia from respiratory droplets from the nose or mouth of an infected person. It is common for people, especially children, to carry the bacteria in their throats without being sick.
