Uno Studio Clinico del Nuovo Vaccino Pneumococcico V118C nei Bambini (V118C-002)

30 settembre 2026 aggiornato da: Merck Sharp & Dohme LLC

Studio di Fase 1, Randomizzato, in Doppio Cieco, Controllato con Comparatore Attivo per Valutare la Sicurezza, la Tollerabilità e l'Immunogenicità di un Nuovo Vaccino Pneumococcico nei Bambini

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.
