Abstract:

The porcine epidemic diarrhea (PED) is an infectious intestinal disease caused by porcine epidemic diarrhea virus (PEDV), which results in an outbreak of diarrhea in pigs and high mortality in newborn piglet. In 2010, a highly pathogenic mutant strain of PEDV emerged and spread globally, which has presently been one of the main pathogens of porcine diarrhea and caused large losses for the global swine industry. Vaccination is the primary measure for preventing and controlling PED. Currently, available commercial PED vaccines mainly consist of traditional inactivated and attenuated vaccines. With the development of genetic engineering technologies in recent years, significant advancements have been made in the study of subunit vaccines, virus-like particle vaccines, recombinant vector vaccines, transgenic plant vaccines, and nucleic acid vaccines. The frequent variations of PEDV continues to bring new challenges to the vaccine development. Therefore, efficient vaccine development platforms and engineering vaccines are crucial for future prevention and control of PED. This article provides a systematic review of the pathogenic characteristics of PEDV and the latest advancements in vaccine research, as well as prospects for future vaccine development, aiming to provide a reference for effective prevention and control of PED.

Key words: porcine epidemic diarrhea (PED), porcine epidemic diarrhea virus (PEDV), inactivated vaccine, attenuated vaccine, engineering vaccine, nucleic acid vaccines
