Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy infants and children aged 2 months to 5 years who have not received any pneumococcal vaccine.

Probably not a fit

Patients with a history of pneumococcal disease or allergic reactions to vaccines may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 3 clinical trial evaluates the immunogenicity and safety of the 13-valent pneumococcal conjugate vaccine (PCV13) developed by Sinovac Life Science Co., Ltd. The study will involve healthy children aged 2 months to 5 years, who will be randomized into two groups to receive either the Sinovac PCV13 or the active control vaccine, Prevenar13®. The trial aims to enroll at least 3080 participants and will be conducted in a double-blind manner to ensure unbiased results.

Why it matters

Potential benefit: If successful, this vaccine could significantly reduce the incidence of pneumococcal infections in young children.

How similar studies have gone: Previous studies of pneumococcal vaccines have shown success in improving immunogenicity and safety profiles.
