MJPRRS® vaccine is a cost-effective new tool in PRRS control in pregnant sows as well as nursery and grow-finish pigs.

Many veterinarians are now recommending MJPRRS® vaccine in both pregnant sows and nursery-grow-finish pigs. Certain results from the field have shown noticeably improved herd health and reduced death loss.

  • Current generation of autogenous killed MJPRRS® vaccine is a tool for PRRS stabilization and control in PRRS positive herds and is not designed for use as a stand alone vaccine in a PRRS naive herd.

  • MJPRRS® vaccine is an autogenous vaccine exclusively produced, distributed, and sold by MVP Labs in Omaha Nebraska. MVP autogenous vaccines are produced in MVP’s licensed facilities and are only available through licensed veterinarians.

  • MJPRRS® autogenous vaccine requires authorization for use by the attending veterinarian.
