an A/Darwin/9/2021 (H3N2)-like virus;
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus; and

It is recommended that trivalent influenza vaccines for use in the 2022 southern hemisphere influenza season contain the following:

Egg-based vaccines

an A/Victoria/2570/2019 (H1N1)pdm09-like virus;
an A/Darwin/9/2021 (H3N2)-like virus; and
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus.

Cell- or Recombinant-based vaccines

an A/Wisconsin/588/2019 (H1N1)pdm09-like virus;
an A/Darwin/6/2021 (H3N2)-like virus; and

On 26 February 2021, WHO published recommendations for the components of influenza vaccines for use in the 2021-2022 northern hemisphere influenza season:

Egg-based Vaccines

an A/Victoria/2570/2019 (H1N1)pdm09-like virus;
an A/Cambodia/e0826360/2020 (H3N2)-like virus;
a B/Washington/02/2019 (B/Victoria lineage)-like virus; and

an A/Cambodia/e0826360/2020 (H3N2)-like virus;
a B/Washington/02/2019 (B/Victoria lineage)-like virus; and
a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.

It was recommended that the influenza B virus component of both trivalent vaccine types for use in the 2021–2022 northern hemisphere influenza season should be a B/Washington/02/2019-like virus of the B/Victoria-lineage.
