Quadrivalent The New Standard

3rd August 2018
Quadrivalent The New Standard

The quadrivalent vaccine offers the same benefits as the trivalent vaccine, with the added bonus of covering  both B-strains, four strains total.


In the past, vaccine manufacturers were only able to include three strains in each season’s vaccine (Trivalent vaccines). The trivalent vaccine includes two types of flu A strain and one of flu B, while the Quadrivalent includes two types of A and two B strains (available since 2013).

A number of manufacturers have started to produce Quadrivalent vaccines, covering all four strains. During the 2017-18 flu season the following strains included in the vaccinations were:

  1. A/Michigan/45/2015 (H1N1)pdm 09-like virus;
  2. A/Hong Kong/4801/2014 (H3N2)-like virus
  3. B/Brisbane/60/2008-like virus
  4. B/Phuket/3073/2013-like virus (included only in Quadrivalent vaccine)

The Quadrivalent vaccine has proved to be partially effective against the H3N2 strain, but highly effective against the 4th strain, which is caused approximately 60% of clinical cases. To learn more click here.
