FDA Approves Audenz For Influenza A Virus H5N1 Subtype

HPAI H5N1 virus is one of the most deadly flu strains known

John G. Baresky

Audenz (Influenza A (H5N1) Monovalent Vaccine, Adjuvanted), developed by Seqirus, has been approved by the FDA. The product is indicated 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. It is administered via intramuscular injection and requires two doses (0.5 mL each) spaced at 21 days apart.

Audenz is a welcome addition to the global vaccine family. Of the few avian influenza A viruses hurdling the species barrier to infect humans, Asian HPAI H5N1 virus has caused the largest number of detected cases of severe disease and death in humans. The virus attacks respiratory systems in people creating significant stress on breathing functions including respiratory failure and pneumonia.

The majority of human infections with Asian HPAI H5N1 are children and adults younger than 40 years old. Mortality has been highest in people aged 10–19 years old and in young adults. HPAI Asian H5N1 virus is considered endemic in poultry in six countries (Bangladesh, China, Egypt, India, Indonesia, and Vietnam), although other nations and regions have experienced outbreaks.
