Heterologous cell-mediated immune responses against PRRS virus in gilts vaccinated intramuscularly and intradermally with UNISTRAIN® PRRS
Miranda, J. et al.; ISERPD 2015.
As expected, the variability of IFN-γ-SC responses observed among different strains was not related to the percentage of ORF5 similarity with the vaccine strain. Results demonstrated that the ID administration of UNISTRAIN® PRRS confers higher levels of cell-mediated immune response than using the IM route. This phenomenon suggests that ID route could be considered a candidate to develop future PRRS vaccines.
