The objective of the study was to assess the CMI response against heterologous PRRSV infection in vitro in gilts vaccinated with UNISTRAIN® PRRS alone or in combination with ERYSENG® PARVO following a common vaccination scheme in commercial farms.

Most of PRRS vaccination programs in commercial farms
consist of a primary immunization with vaccination and
revaccination 3-4 weeks apart and, then, a booster dose every
3-4 months. Results of the present study suggest that
UNISTRAIN® PRRS administered alone or combined with
ERYSENG® PARVO induces a significant specific CMI response
against heterologous PRRSV strains after a common
vaccination scheme with primary vaccination and revaccination
4 months later.
