Official Title: A Phase 3, Randomized, Active-Controlled, Double-blind Trial of the Safety, Tolerability, and Immunologic Non-Inferiority of a 13-valent Pneumococcal Conjugate Vaccine Compared to a 7-valent Pneumococcal Conjugate Vaccine in Healthy Infants Given With Routine Pediatric Vaccinations in Germany.
