Study of Mixed Vaccination Schedules With a 21-valent Pneumococcal Conjugate Vaccine and a 20-valent Pneumococcal Conjugate Vaccine in Healthy Infants From Approximately 2 Months of Age

This study is a Phase 3, randomized, modified double-blind study which aims to measure whether the investigational pneumococcal conjugate vaccine PCV21 is safe and can help the body to develop germ-fighting agents called "antibodies" (immunogenicity) when it is given after 1 dose, 2 doses, or 3 doses of a licensed …

20-valent Pneumococcal Conjugate Vaccine Safety and Immunogenicity Study of a 4-Dose Series in Healthy Infants

20-valent Pneumococcal Conjugate Vaccine Safety and Immunogenicity Study of a 4-Dose Series in Healthy Infants

Study to Evaluate the Safety Tolerability and Immunogenicity of V114 in Healthy Japanese Infants (V114-033)

The purpose of this clinical study is to evaluate the safety and immunogenicity of a 4-dose schedule (3-dose primary series followed by a toddler dose) of V114 compared with Pneumococcal 13-valent Conjugate Vaccine (PCV13). The hypothesis is that V114 is non-inferior to PCV13 for the 13 shared serotypes between V114 …

Immunogenicity and Safety Study of a Quadrivalent Meningococcal Conjugate Vaccine Administered Concomitantly With Routine Pediatric Vaccines in Healthy Infants and Toddlers

The primary objective of this study is to demonstrate the non-inferiority of the vaccine seroresponse to meningococcal serogroups A, C, Y, and W following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO when given concomitantly with routine pediatric vaccines to infants and toddlers 6 …

Safety and Immunogenicity of a Quadrivalent Meningococcal Conjugate Vaccine When Administered Concomitantly With Routine Pediatric Vaccines in Healthy Infants and Toddlers in the Russian Federation and Mexico

Primary Objective: To describe the antibody titers to the antigens (meningococcal serogroups A, C, Y, and present in MenACYW conjugate vaccine or Menveo measured by serum bactericidal assay using human complement (hSBA), for Groups 1 and 2 when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in …

Safety and Immunogenicity of a Quadrivalent Meningococcal Conjugate Vaccine When Administered Concomitantly With Routine Pediatric Vaccines in Healthy Infants and Toddlers in the Russian Federation and Mexico (MET33)

Primary Objective: To describe the antibody titers to the antigens (meningococcal serogroups A, C, Y, and present in MenACYW conjugate vaccine or Menveo® measured by serum bactericidal assay using human complement (hSBA), for Groups 1 and 2 when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in …
