Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to evaluate the safety and tolerability of three dose levels of ASP3772 in comparison to the active comparator Prevnar 13® (PCV13) in toddlers who have previously been administered the routine three-dose series of PCV13.
