Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is a randomized, double-blind, controlled phase Ⅳ clinical trial. And 920 infants will be assigned to investigational group and controlled group in a 1:1 ratio. The investigational vaccine is manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd. The controlled vaccine is manufactured by Shanghai institute of biological products Co., Ltd.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The seroconversion rate of hemagglutination inhibition (HI) antibody
Time Frame: the 30th day after vaccination
Immunogenicity index, One of the standard to evaluate the immunogenicity of experimental vaccine
the 30th day after vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The GMT of HI antibody
Time Frame: the 30th day after vaccination
Immunogenicity index, Another standard to evaluate the immunogenicity of experimental vaccine
the 30th day after vaccination
The incidence of the solicited local and systemic adverse reactions
Time Frame: from day 0 to day 14 after vaccination
Safety index, The adverse reactions refers to the adverse events which were considered related to the vaccination
from day 0 to day 14 after vaccination
The incidence of the unsolicited adverse events
Time Frame: from day 0 to day 30 after immunization
Safety Index
from day 0 to day 30 after immunization
The incidence of the serious adverse events
Time Frame: from day 0 to day 30 after immunization
