Abstract: The vaccine immunization is an important tool to prevention and control of porcine reproductive and respiratory syndrome currently. The traditional PRRS vaccines played a major role in preventing and controlling porcine reproductive and respiratory syndrome,variation with the acceleration of PRRSV,the traditional PRRSV vaccines can not afford full protection in recent years. With the development of genetic engineering technology,a number of new vaccines developed very rapidly,some vaccines have been commercialized on the market and widely applied to production,it gives human and animal disease prevention and treatment has brought new hope. Although the new vaccine is also flawed,but as molecular biology,immunology and other disciplines,the development of new vaccines through constant transformation,will better serve the sustainable development of humans and livestock.

Key words: PRRSV vaccines; traditional vaccines; new vaccines; new progress
