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.

Ages Eligible for Study

6 months to 5 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

In this study,only children aged 6-71 months old who were judged by vaccination doctors to be eligible for vaccination and voluntary and self-funded completion of EV71 vaccine combined immunization with one of the other type I or II vaccines were enrolled.

Description

Inclusion Criteria:

  • 6 months ≤ Age of enrollment ≤71 months;
