ABSTRACT:
Chimeric replicons of North American Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) containing the 5′ sequence of an avirulent strain of PRRSV and a 3′ sequence of a virulent strain of PRRSV are provided. Further provided is a method of producing attenuated PRRSV from the chimeric replicon. Also provided are compositions containing the replicon or attenuated virus. Vaccines and a method of vaccinating pigs against PRRSV are also provided.
