PDS0202 (Y2 + NG2 COBRA proteins) prevents viral replication in the lungs of ferrets after vaccination followed by viral challenge with A/Victoria/2570/2019 H1N1 flu strain (1e6 PFU/mL). The quantity of H1N1 virus stays below the detection limits. The vaccine based on the wild type HA (Mich/15 + Sing/16) and the control (Mock) do not effectively prevent replication and expansion of the H1N1 virus in the lungs of the ferrets.
