This study is an open-label phase Ⅳ clinical trial of the inactivated SARS-CoV-2 vaccine(CoronaVac)manufactured by Sinovac Research \& Development Co., Ltd. The purpose of this study is to evaluate the immunogenicity and safety of the Inactivated SARS-CoV-2 Vaccine (Vero Cell) in Healthy Population Aged From 18 to 59 Years.

Read the detailed description

This study is an open-label phase Ⅳ clinical trial in healthy adult aged 18-59 years. The experimental vaccine was manufactured by Sinovac Research and Development Co.,Ltd.. A total of 1400 subjects will be enrolled,the safety and immunogenicity of booster immunization were evaluated in 400 subjects (group A) who received two doses of primary immunization at an interval of 21 to 31 days. And the safety of booster immunization was evaluated in the extended safety group (group B), which included 1000 subjects.

    GMT of the neutralizing antibody to live SARS-CoV-2 within 1month after booster immunization of the Inactivated SARS-CoV-2 vaccine.

    Measured: 1 month after booster immunization

  2. Safety index-incidence of adverse reactions

    Incidence rate of adverse reactions within 1 month after booster immunization of the Inactivated SARS-CoV-2 vaccine

    Measured: 1 month after booster immunization

Secondary outcomes (3)
  1. Safety index-incidence of serious adverse events

    Incidence rate of serious adverse events within 1 month after booster immunization of the Inactivated SARS-CoV-2 vaccine

    Measured: 1 month after booster immunization

  2. Seroconversion rate,seropositivity rate and GMI of the neutralizing antibody to SARS-CoV-2

    Seroconversion rate,seropositivity rate and GMI of the neutralizing antibody to SARS-CoV-2 within 1 month after booster immunization of the Inactivated SARS-CoV-2 vaccine

    Measured: 1 month after booster immunization

  3. Seropositivity rate of IgG antibody

    Seropositivity rate of IgG antibody within 1 month after booster immunization of the Inactivated SARS-CoV-2 vaccine

    Measured: 1 month after booster immunization

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing SARS-CoV-2 Inactivated Vaccine and The SARS-CoV-2 Inactivated Vaccine in people with COVID-19, run by Sinovac Research and Development Co., Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 24 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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 Jiang Wu, Master (13381081732, wj81732@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Geometric mean titer(GMT) of neutralizing antibody to live SARS-CoV-2 (time frame: 1 month after booster immunization). The study lists 2 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?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2021.
