Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes

You may qualify if:

  • Different age groups from 18 to 60 years, with normal intelligence and health. Volunteers (or their guardians) are well informed of the situation and sign the consent
  • Vaccination recipients qualified for this product have been inquired about medical history and clinically proven to be healthy
  • Requests of clinical research program can be obeyed

  • Volunteers allergic to ingredient of vaccine composition (can be checked from vaccination history), especially to egg
  • History of progressive or severe neurologic disorder
  • Serious adverse reactions to vaccines such as anaphylaxis, hives, respiratory difficulty, angioedema, or abdominal pain
  • Known or suspected impairment/alteration of immune function, for example receiving immunosuppressive therapy or receiving blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation
  • Asthma that is unstable or required emergent care, hospitalization or intubation during the past two years or that required the use of oral or intravenous corticosteroids
  • Bleeding disorder diagnosed by a doctor (e.g. factor deficiency, coagulopathy, or platelet disorder requiring special precautions) or significant bruising or bleeding difficulties with IM injections or blood draws
  • History of thyroidectomy or thyroid disease that required medication within the past 12 months
  • Serious angioedema episodes within the previous 3 years or requiring medication in the previous two years
  • Guillain-Barre Syndrome
  • Self-reported seropositivity for Human Immunodeficiency Virus (HIV), Hepatitis B, or Hepatitis C
  • Any other vaccines or immunoglobulin preparation within 1 weeks prior to enrollment
  • Axillary temperature ≥ 38.0 degrees Celsius within 3 days of intended study vaccination
  • Any conditions may influence the evaluation
