A Study of the Immunogenicity, Tolerability, and Safety of a New Formulation of RotaTeq™ in Infants (V260-035)
2018年10月19日 更新者：Merck Sharp & Dohme LLC
A Double-blind, Randomized, Controlled, Multicenter Study to Evaluate the Safety, Tolerability, and Immunogenicity of a New Formulation of RotaTeq™
A study to compare safety, tolerability, and immunogenicity of a new formulation of RotaTeq™ with the existing formulation in infants.
The primary hypothesis of the study is that the new formulation will be noninferior to the existing formulation on the basis of immunogenicity.

An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the product.
Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an adverse event.
Protocol-defined Tier-1 adverse events to be collected up to 7 days after any vaccination were diarrhea, vomiting, elevated temperature (rectal >=38.1°
C, >=100.5°
F), and irritability.
