The second and third years of the SARS-CoV-2 pandemic have been marked by the repeated emergence and replacement of ‘variants’, the most recent examples being Delta and Omicron.

Researchers from theme 5 of the PROTECT NCS presented their work at this year’s Options conference in Belfast, which is the only global scientific meeting with a dedicated focus on influenza. Their poster describes a hamster contact exposure challenge model to assess protection conferred by vaccination or prior infection against re-infection.
