Where are the influenza vaccines made?

AFLURIA QUAD JUNIOR, INFLUVAC TETRA, AFLURIA QUAD and FLUAD QUAD are manufactured in the UK or the USA.

How are influenza vaccines produced?

  • FLUAD QUAD is an inactivated vaccine that contains inactivated haemagglutinin proteins from the surface of the virus and a squalene-based oil-in-water emulsion. Influenza virus is grown in embryonated hens’ eggs and inactivated with formaldehyde. The haemagglutinin protein for each strain is harvested, purified and combined with the MF59 squalene-based oil-in-water adjuvant.
  • AFLURIA QUAD and AFLURIA QUAD JUNIOR are split virion vaccines that contain disrupted haemagglutinin proteins from the surface of the virus. Influenza virus is grown in embryonated hens’ eggs from disease-free flocks and inactivated. The haemagglutinin protein for each strain is harvested, purified and inactivated for use in the vaccine.
  • INFLUVAC TETRA is an inactivated vaccine that contains inactivated haemagglutinin proteins from the surface of the virus. Influenza virus is grown in embryonated hens’ eggs and inactivated with formaldehyde.

Do we have to use the needles sourced by Seqirus to administer AFLURIA QUAD or FLUAD QUAD?

No. At the time of vaccination, the choice of needle gauge and length will be based on the vaccinator’s clinical judgment to ensure needle length is appropriate to reach muscle. Table 2.8 in the online Immunistaion Handbook 2020 provides guidance on the needle gauge and length by site and age:

Age Site Needle guage and length Rationale
5–6 years Deltoid 23–25 G x 16 mm A 16 mm needle should be sufficient to effect deep IM deposition in the deltoid in most children.
7–64 years
65 years or older
Deltoid 23–25 G x 16 mm
23–25 G x 25 mm
21–22 G x 38 mm
Most adolescents and adults will require a 25 mm needle to effect deep IM deposition.
Very large or obese person Deltoid 21–22 G x 38 mm Use clinical judgment to ensure needle length is appropriate to reach muscle.
