Influvac® Tetra

Influvac® Tetra is an inactivated (surface antigen), quadrivalent influenza vaccine indicated for the prophylaxis of influenza, especially in those who run an increased risk of associated complications.

The composition of Influvac® Tetra complies with the WHO recommendations on the composition of influenza vaccines.1

Influvac® Tetra is indicated in adults and children from 3 years of age2.

What are the advantages of Influvac® Tetra?1

  • Influvac® Tetra provides active immunisation against 4 influenza virus strains. The constituents of Influvac® for the 2019/2010 season, as recommended by the World Health Organization, are as follows:
    • - an A/Brisbane/02/2018 (H1N1)pdm09-like virus;
    • - an A/Kansas/14/2017 (H3N2)-like virus;
    • -a B/Colorado/06/2017-like virus B/Victoria/2/87 lineage); and
    • -a B/Phuket/3073/2013-like virus (B/Yamagata/16/88 lineage)3.
  • Influvac® Tetra can be used in all stages of pregnancy and during breastfeeding.1
  • Influvac® Tetra is available in pre-filled, single-dose syringe (Single packs: syringes with needles. Packs of ten: Syringes can be ordered with/without needle).1
  • The safety profile of Influvac® Tetra builds on the well established safety profile of the trivalent vaccine, Influvac®.1

Influvac® Tetra with 4 influenza virus strains potentially offers a wider protection in case of vaccine strain mismatch.1,4

Since 1985, 2 antigenically distinct lineages of influenza B viruses (Victoria and Yamagata) have been co-circulating globally.5

Trivalent influenza vaccines contain only one B-strain; therefore, mismatch can occur between the recommended lineage for TIV and the circulating B-strain.4

Vaccine mismatch for circulating B strain was noted in 5 of the 10 previous influenza seasons (2001–2002 through 2010–2011).4

In the 2017-2018 season (till week 10/2018) in Europe, more influenza type B (66%) than type A (34%) viruses were detected.5
