入选标准
- •Subjects aged 18 years and above, including those with underlying diseases and immunocompromised subjects.
- •Basic or booster immunization with COVID-19 vaccine ≥6 months.
- •≥3 months of SARS-CoV-2 infection history, or never infected.
- •Have the ability to understand research procedures, with informed consent, voluntarily sign informed consent, and be able to comply with the requirements of clinical research protocols.
排除标准
- •Axillary temperature ≥37.3℃.
- •SARS-CoV-2 antigen or nucleic acid screening positive within the last 48 hours.
- •Anti-SARS-CoV-2 IgM antibody was positive during the screening period.
- •It is in the advanced stage of malignant tumor and the disease control is unstable.
- •Female pregnancy (pregnancy test results are positive), lactation period.
- •Have serious cardiovascular diseases, such as arrhythmia, conduction block, myocardial infarction, heart failure, severe hypertension, and can not be controlled by drugs.
- •Have other serious chronic conditions such as uncontrolled asthma, diabetes, chronic obstructive pulmonary disease, pulmonary embolism, chronic kidney disease requiring dialysis, cirrhosis of the liver, convulsions, epilepsy and other neurological/psychiatric conditions.
- •Have been diagnosed with congenital or acquired immunodeficiency, HIV infection.
- •People who are allergic to any component of the investigational vaccine have a history of more severe allergies or allergic reactions to the vaccine in the past.
- •Congenital or acquired angioedema/neuroedema.
- •Asplenia or functional asplenia.
- •Thrombocytopenia or other clotting disorders (which may cause intramuscular injection contraindications).
- •Received another investigational drug within 1 month prior to receiving the investigational vaccine.
- •Received subunit or inactivated vaccine within 14 days prior to receiving the investigational vaccine, or received live attenuated vaccine within 1 month.
- •Fertile female subjects did not use effective contraception within 1 month prior to enrollment.
- •Fertile female and male subjects have pregnancy plans and sperm/egg donation plans from the screening period to 3 months after immunization.
- •Abnormal laboratory test results during the screening period, which were judged by the researcher to be unsuitable for the study vaccine.
- •Medical, psychological, social, or other conditions that, in the investigator's judgment, are inconsistent with the protocol or affect the subject's signing of informed consent.
