The invention relates to the field of veterinary biological products, in particular to a porcine epidemic diarrhea virus attenuated strain and a vaccine and application thereof. The porcine epidemic diarrhea virus attenuated strain provided by the invention is obtained through in-vitro separation culture and continuous five rounds of plaque purification and screening technology, and has stable culture characteristics. Meanwhile, the virulence of the strain on newborn piglets and weaned piglets is remarkably reduced, and the virulence does not have the phenomenon of reversion after continuous passage for five times in a pig body. The strain has good immunogenicity, and mucosal immunity and systemic immune response of an organism can be activated at the same time by adopting an oral immunization mode. A neutralizing antibody of 1: 8-1: 16 can be detected in oral fluid and serum after the piglets are immunized for 14 days, and a large amount of sIgA is generated in milk after the pregnant sows are immunized, so that the piglets obtain effective passive immune protection.
