ncov-s.fasta and vaccine-s.fasta contain the same sequence which appears to be the virus sequence (if I compare with side-by-side.csv). For example, the first two codons for the vaccine according to side-by-side.csv is ATG-TTC, however if you look at the first two codons in vaccine-s.fasta the first two codons are ATG-TTT.
