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

Descrizione dettagliata
Stage 1 of the study will be conducted in toddlers enrolled at 12 through 15 months of age who previously completed a primary 3-dose infant series with a licensed pneumococcal conjugate vaccine (PCV). Stage 2 will be conducted in infants enrolled at approximately 2 months of age, who will receive the 3+1 schedule (3 infant doses followed by a toddler dose).
