PRRS vaccine overcomes maternal immunity in day-old piglets

A new vaccine for porcine reproductive and respiratory syndrome (PRRS) has been shown to overcome maternal immunity in newborn piglets, offering protection from this costly disease from before weaning through slaughter.
Speaking to Pig Health Today at the recent PROHEALTH Symposium in Ghent, Belgium, Tom Meyns, DVM - a swine veterinarian at Zoetis - said vaccination has long been an effective strategy for controlling PRRS, which causes a host of reproductive issues in sows as well as mortality, illness and production losses in growing pigs.
