The invention relates to a vaccine against coronavirus infections and, in particular, against feline infectious peritonitis (FIP). The inventive vaccine comprises immunogenic peptides included in the S protein of feline coronaviruses (FcoV), which do not result from immunologic enhancement. The invention also relates to the use of at least one peptide for the preparation of a vaccine that induces protection against coronavirus infections, said peptide being selected from the group comprising fragments of an S protein of coronavirus of at least 12 amino acids, included in the SEQ ID NO: 5, or nucleic acid fragments of at least 36 nucleotides, included in the SEQ ID NO: 10 and coding for one of said peptides.
