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.

结局指标

主要结局

AE and AR

时间窗: 0-7 days after vaccination
