The invention concerns a baculovirus expression vector for recombinantly expressing a Foot-and-mouth disease virus (FMDV) capsid precursor protein under control of a promoter, the expression vector comprising a nucleic acid sequence encoding the FMDV capsid precursor protein, wherein the ATG start codon of an open reading frame encoding the FMDV capsid precursor protein © is preceded at position −4 to −1 by the nucleic acid sequence 5′-AAAT-3′. The invention further relates to a host cell comprising the baculovirus expression vector, a method of producing FMDV virus-like particles (VLPs), and a method of producing a vaccine.
