入选标准

  • Age at enrollment is ≥65 years (including the 65th birthday).
  • The participant voluntarily agrees to take part in the trial and has signed the informed consent form.
  • The participant is able to comply with the trial follow-up schedule as required by the protocol (i.e., no plans for long-term absence or relocation from the study site).
  • Medically stable: The participant may have underlying chronic conditions such as hypertension, diabetes, ischemic heart disease, or hypothyroidism, but symptoms/signs must be controlled. If the participant is on any medication, the dosage must have remained stable for at least three weeks prior to vaccination.

排除标准

  • Axillary temperature >37.0°C.
  • Confirmed influenza virus infection by laboratory test or self-test kit positive within the past 12 months.
  • Received any influenza vaccine (licensed or investigational) within the past 12 months or plans to receive any influenza vaccine during the study.
  • Known or suspected allergic to any component of the investigational vaccine.
  • A history of severe allergic reactions to any vaccines or medications (for example, but not limited to: anaphylactic shock, allergic laryngeal edema, allergic purpura, thrombocytopenic purpura, local allergic necrotic reaction (Arthus reaction)).
  • Congenital malformations or developmental disorders, and genetic defects or severe malnutrition.
  • History of convulsions or seizures, epilepsy, psychiatric disorders, or relevant family history.
  • Severe liver and kidney diseases, malignant tumors, various acute diseases, or being in the acute exacerbation stage of a chronic disease.
  • Diagnosed with congenital or acquired immunodeficiency, HIV infection, lymphoma, leukemia, or other immune-mediated/autoimmune diseases.
  • A history of asthma, unstable within the past two years requiring emergency treatment, hospitalization, intubation, or oral/intravenous corticosteroids.
  • Individuals who have received immunostimulant or immunosuppressant therapy within the past 6 months (continuously administered orally or via drip infusion for more than 14 days).
  • Suffering from severe cardiovascular diseases (e.g., heart disease, cor pulmonale, pulmonary edema).
  • Blood pressure ≥150/100 mmHg despite medication control.
  • History of live attenuated vaccine within 28 days prior to vaccination, or any other vaccine within 14 days prior to vaccination.
  • Diagnosed with progressive neurological diseases, or a history of Guillain-Barré syndrome.
  • Asplenia or functional asplenia, including splenectomy due to any reason, or resection/partial removal of other vital organs.
  • Received blood or blood-derived products within the past 6 months.
  • A diagnosed history of coagulation disorders (e.g., coagulation factor deficiencies, coagulopathies, platelet disorders).
  • Currently undergoing anti-tuberculosis treatment.
  • Clinically significant abnormalities in laboratory tests (blood biochemistry, blood routine and urine routine) as determined by the investigator.
  • Any condition that, in the opinion of the investigator, makes the participant unsuitable for this clinical trial.
