Audenz (influenza A (H5N1) monovalent vaccine, adjuvanted) is a cell-based influenza vaccine designed to protect against influenza A (H5N1) in the event of a pandemic.

  • An influenza pandemic is a global epidemic caused by the emergence of a new influenza virus to which there is little or no pre-existing immunity in the human population.
  • Audenz is approved for use in persons 6 months of age and older at increased risk of exposure to the influenza A virus H5N1 subtype contained in the vaccine.
  • Audenz combines two leading-edge technologies - MF59® adjuvant and cell-based antigen manufacturing. The adjuvant reduces the amount of antigen required to produce an immune response, increasing the number of doses of the vaccine developed so that a large number of people can be protected as quickly as possible.
  • Audenz is a two-dose immunization series. The two doses are administered via intramuscular injection 21 days apart.
  • Common side effects include injection site pain, fatigue, headache, malaise, joint and muscle pain, and nausea. Hypersensitivity reactions can occur and appropriate medical treatment must be available to manage possible anaphylactic reactions following administration of the vaccine.
