Recently published results from a controlled, randomised trial in UK concluded that concomitant vaccination with one of two SARS-CoV-2 vaccines (ChAdOx1 or BNT162b2) plus an age-appropriate influenza vaccine raised no safety concerns and preserves antibody responses to both vaccines.

Vaccine composition
On 24 September 2021, WHO published recommendations for the components of influenza vaccines for use in the 2022 southern hemisphere influenza season:
Egg-based Vaccines
-
an A/Victoria/2570/2019 (H1N1)pdm09-like virus;
-
an A/Darwin/9/2021 (H3N2)-like virus;
-
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus; and
-
a B/Phuket/3073/2013 (B/Yamagata 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;
-
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus; and
-
a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.

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
-
a B/Austria/1359417/2021 (B/Victoria lineage)-like virus

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
-
a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.
Cell- or recombinant-based Vaccines
-
an A/Wisconsin/588/2019 (H1N1)pdm09-like virus;
-
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.
