Phase 1
Completed
Conditions
Pneumococcal Infections
Interventions
Biological: V114, Aluminum Nonadjuvanted
Biological: Prevnar™
Biological: V114, Aluminum Adjuvanted
Registration Number
NCT01215175

Brief Summary

This study is being conducted to evaluate the safety, tolerability, and immunogenicity of 15-valent pneumococcal conjugate vaccine (V114) compared to Prevnar™ in healthy adults and toddlers.

Detailed Description

The study was extended to obtain additional sera from adult participants to support further development, validation, and performance of anti-pneumococcal antibody assays.

Primary Outcome Measures
NameTimeMethod
Adult: Percentage of Participants With Any Adverse EventUp to Day 14 after vaccination

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

Toddler: Percentage of Participants With Any Serious Adverse EventUp to Day 14 after vaccination

A serious adverse event (SAE) is an AE that results in death, is life threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment.

Toddler: Percentage of Participants With Any Adverse EventUp to Day 14 after vaccination

An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

Adult: Percentage of Participants With Any Vaccine-related Adverse EventUp to Day 14 after vaccination

An AE is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. Relatedness of the AE to study vaccine was determined by the investigator.
