Even though the vaccine was designed before the emergence of the Alpha, Beta, Gamma, Delta and Omicron variants of SARS-CoV-2 in 2020, it provided a strong protection against all of these and against more recent variants, suggesting that vaccines developed within this consortium may also protect against future SARS-CoV-2 variants. The results are reported in the journal Nature Biomedical Engineering.
