Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A total of 1200 people aged 18 years and older who have completed two or three-dose inactivated COVID-19 vaccine for 6-18 months will be recruited in this study. Subjects will be received 1 dose at day 0 as a booster vaccination.Immunogenicity and safety of Recombinant SARS-CoV-2 Vaccine (CHO Cell) LYB001 will be evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is a randomized, double-blind, positive control design and 1200 subjects are randomly assigned to LYB001 and positive control groups in a 1:1 ratio to evaluate the safety and immunogenicity as a booster vaccination.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy subjects aged 18 years and older, including both males and females;
* Subjects who agree to participate in this clinical trial voluntarily and sign the informed consent form, are capable of providing valid identification, understanding and complying with the requirements of the clinical protocol.

* For female participants of childbearing potential, effective contraception measures should be used within 2 weeks prior to participation in this study and the results of pregnancy test is required to be negative. Participants should voluntarily agree to use effective contraceptive measures from the time of signing the informed consent form to the end of the study (effective contraceptive measures including oral contraceptives (excluding emergency contraceptives), injectable or implantable contraceptives, sustained-release topical contraceptives, hormonal patches, intrauterine device, sterilization, abstinence, condoms (for males), diaphragms, cervical caps, etc.).

Exclusion Criteria

* Receipt of any COVID-19 prophylactic medication other than inactivated COVID-19 vaccine (e.g., receipt history of any approved or under developing COVID-19 vaccines, or other COVID-19 prophylactic medication, etc.), or previous vaccination history other than two- or three-dose inactivated COVID-19 vaccination;
* Systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg or axillary body temperature ≥ 37.3°C prior to enrolment;
* Known allergy, or history of anaphylaxis or other serious adverse reactions to vaccines or their excipients;
* History of severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS);
* History of COVID-19, or close contact with a confirmed/suspected COVID-19 patient or positive results for SARS-CoV-2 nucleic acid ;
* Receipt of any live attenuated vaccine within 28 days prior to vaccination, and other vaccines such as subunit and inactivated vaccine within 14 days prior to vaccination;
* Receipt of blood or blood-related products, including immunoglobulins, monoclonal antibodies, within 3 months prior to vaccination; or any planned use during the study period.
* Subjects with the following diseases:

1. Any acute diseases or acute attacks of chronic diseases within 7 days prior to enrolment;
2. Congenital malformations or developmental disorders, genetic defects, severe malnutrition, etc.;
3. Congenital or acquired immunodeficiency or autoimmune disease, or long-term receipt (\>14 consecutive days) of glucocorticoid (reference value for dose: ≥20 mg/day prednisone or equivalent) or other immunosuppressive agents within the past 6 months, with exception of inhaled or topical steroids, or short-term use (≤14 consecutive days) of oral corticosteroids;
4. Currently suffering from or diagnosed with infectious diseases, such as hepatitis B, hepatitis C, syphilis, AIDS etc.;
5. History or family history of neurological disorders (convulsions, epilepsy, encephalopathy, etc.) or psychiatric disorders;
6. Asplenia, or functional asplenia;
7. Presence of severe, uncontrollable or hospitalized cardiovascular diseases, endocrine diseases, blood and lymphatic diseases, immune diseases, liver and kidney diseases, respiratory diseases, metabolic and skeletal diseases, or malignant tumors;
8. Contraindications to IM injections and blood draws, such as coagulation disorders, thrombotic or bleeding disorders, or conditions that needs continuous anticoagulant usage.
* Drug or alcohol abuse (alcohol intake ≥ 14 units per week) which in the investigator's opinion would compromise the participant's safety or compliance with the study procedures;
* Pregnant or lactating females;
* Having participated or participating in COVID-19 related clinical trials, and those participating or planning to participate in other clinical trials during the study period;
* Presence of any underlying disease or condition which, in the opinion of the investigator, may place the subject at unacceptable risk, is unable to meet the requirements of the protocol, or interfere with the assessment of vaccine response
