    Measured: Before the 3th dose (Day 0)

  3. Neutralizing antibody level

    Neutralizing antibody GMT against coronavirus after the 3th dose

    Measured: 28 days after the 3th dose (Day 28)

  4. Neutralizing antibody level

    Neutralizing antibody GMT against coronavirus after the 3th dose

    Measured: 6 months after the 3th dose

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hanqing He ((0571)87115111, hanqinghe@cdc.zj.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Seroconversion rate (time frame: 28 days after the 3th dose (Day 28)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
