Vaccination with UNISTRAIN® PRRS significantly reduced the clinical respiratory signs associated with PRRS and the percentage of antibiotic treatments. Moreover, vaccination reduced the percentage of animals with lung lesions and positive to PRRSV. Moreover, vaccination significantly improved the ADWG of the piglets after a PRRS outbreak. Therefore, UNISTRAIN® PRRS is effective in piglets and it is a useful tool to reduce the negative clinical and productive consequences of a PRRS outbreak.
