    Abstract: A computer-implemented method of selecting one or more amino acid sequences for inclusion in a vaccine from a set of predicted immunogenic candidate amino acid sequences includes identifying an immune profile response value for each candidate amino acid sequence with respect to each one of a plurality of sample components of an immune profile. The immune profile response value represents whether the respective candidate amino acid sequence results in an immune response for the sample components of the immune profile. A plurality of immune profiles are retrieved for a population. A plurality of representative immune profiles are generated for the population. The representative immune profiles overlap with the sample components of the immune profiles. The one or more amino acid sequences for inclusion in the vaccine that minimises a likelihood of no immune response for each representative immune profile, based on the immune profile response values, are selected.
