Flublok Quadrivalent Influenza Vaccine

Flublok Quadrivalent Description

Flublok is a recombinant influenza vaccine. 

For 2020-2021, cell- or recombinant-based vaccines are recommended to contain:

  • A/Hawaii/70/2019 (H1N1)pdm09-like virus (updated)

  • B/Washington/02/2019 (B/Victoria lineage)-like virus (updated)
  • B/Phuket/3073/2013-like (Yamagata lineage) virus
