Positions showing statistically significant differences in Shannon entropy between controls and vaccinees.

The sequences of all vaccinees were compared against the sequences of all control animals or the sequences of vaccines were divided according to the vaccination protocol (groups 1 and 2) and compared against controls. The last column shows the nucleotide sites-of-interest identified using a Bayesian model.CT: cytoplasmic tail.no: sites not identified by the Bayesian tool.
