Niemann, O. et al.; IPVS 2014.
The results may be indicative of a decrease in the infection pressure exerted by PRRSV in the nursery as a consequence of the active vaccination of the sows. Nevertheless, it was not possible to eradicate the infection from the herd, but the productive parameters show clinical and virological stabilization of the breeding herd and the nursery.
Notas
Niemann, O. et al.; IPVS 2014.
After the change of vaccine the reproduction data of the farm improved. No side effects occurred and the production was successfully stabilized. Nevertheless the transmission of PRRSV from sows to piglets couldn`t be found the nursery remained PRRSV positive and showed clinical signs of PRDC. A full clinical stabilisation would require a piglet vaccination.
Notas
Miranda, J. et al.; ESPHM 2015.
When discussing about PRRS vaccine strain efficacy, one of the most important challenges for any vaccine strain is their ability to confer heterologous protection in front of arrival of new field strains.. The present study is a good example to demonstrated that in front the same field challenge, the strain contained into UNISTRAIN® PRRS confers better heterologous protections than another EU strain MLV vaccine.

Vaccination with the combined administration of ERYSENG® PARVO and UNISTRAIN® PRRS significantly reduced the percentage of viraemic gilts and the duration of viraemia in gilts after a heterologous PRRS infection. Also, the combined use of the vaccines reduced vertical and horizontal transmission to their piglets. The results obtained allow the conclusion to be drawn that the efficacy in terms of viraemia after a PRRS challenge with the combined use of the two vaccines is comparable to that of UNISTRAIN® PRRS administered alone.
Notas
Miranda, J. et al.; ESPHM 2015.
After gilt infection, piglets from the vaccinated gilts were heavier when weaned and grew faster than piglets from the control gilts. Overall piglet performance was significantly better in piglets born from vaccinated gilts with the combined administration of ERYSENG® PARVO and UNISTRAIN®PRRS.
Notas
Miranda, J. et al.; ESPHM 2015.
The combined administration of ERYSENG® PARVO and UNISTRAIN® PRRS significantly reduced the number of weak piglets and the presence of mummies in vaccinated gilts after a heterologous PRRSv challenge. So the use of the vaccine mixture clinically protected gilts from a heterologous PRRSv infection. The results obtained allow the conclusion to be drawn, that efficacy in terms of clinical protection after a PRRS challenge with the combined use of the two vaccines is comparable to that of UNISTRAIN® PRRS administered alone.

Notas
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.
Notas

Miranda, J. et al.; IPVS 2014.
Genetic/antigenic diversity and variability in the immunobiological properties of the PRRSV (3,4) may compromise the heterologous protection generated by vaccination in PRRS control strategies. Although PRRS immunity is not yet fully understood, the significance not only of the NA but the cell-mediated immunity is important for a better understanding of vaccine performance (3). The present study showed that primo-immunization of naïve gilts with UNISTRAIN® PRRS induced a significant specific cell-mediated immunity against 5 heterologous PRRSV strains.
