Abstract

The present invention discloses a gene vaccine for resisting SARS coronavirus and its application, including eucaryotic expressino plasmid containing total or partial gene fragment of total-length gene sequence of SARS coronavirus S protein. The nucleotide sequence of coded SARS coronavirus S protein can be operatively connected with a promotor, then it can express the complete or partial polypeptide of the coded SARS coronavirus S protein in vivo. The described gene vaccine can be used for immunizing host including human body and rodent, for example mouse to make it produce specific protective body fluid immune and cell immune to resist the infection of SARS coronavirus. Said invention is good in stability, convenient in production and low in cost.
