The trivalent influenza vaccines now contain the following virus strains:

  • A/Michigan/45/2015 as the H1N1-like component (as last year)
  • A/Singapore/INFIMH-16-0019/2016 as the H3N2-like component
  • B/Colorado/06/2017 as the influenza B component.

The tetravalent vaccines contain the additional influenza B strain B/Phuket/3073/2013, the same as last season.

This year sees the launch of two new tetravalent vaccines (Influvac Tetra and Influenza Vaccine Tetra MYL) and two new trivalent vaccines (Fluad and Influenza Vaccine, Mylan). The new trivalent vaccine Fluad contains an adjuvant to increase its immunogenicity in adults aged 65 years and over and is recommended by the Joint Committee on Vaccination and Immunisation for use in this age group.

The live attenuated tetravalent influenza vaccine Fluenz Tetra, which is given as an intranasal spray, continues to be indicated for use in the routine childhood immunisation schedule. It should be offered to children aged 2 to 9 years on 31st August 2018.

Agrippal and Sanofi Pasteur's Inactivated Influenza Vaccine BP are no longer available.
