Badanie kliniczne nowej szczepionki przeciwko pneumokokom V118C u dzieci (V118C-002)

30 września 2026 zaktualizowane przez: Merck Sharp & Dohme LLC

Faza 1, randomizowane, podwójnie ślepe badanie z aktywnym komparatorem kontrolnym oceniające bezpieczeństwo, tolerancję i immunogenność nowej szczepionki przeciw pneumokokom u dzieci

Researchers are looking for new vaccines to prevent pneumococcal disease, which is any infection in the lungs or other parts of the body that is caused by a type of bacteria called Streptococcus pneumoniae. V118C is a new vaccine designed to help prevent disease from Streptococcus pneumoniae bacteria.

This study will look at V118C in toddlers and infants. The goal of the study is to learn how safe V118C is for children and how well they tolerate it.
