Effect of early PRRSV (Porcine Reproductive and Respiratory Syndrome virus) vaccination on pig health and performance: the earlier the better?

Vaccination is a cornerstone of infectious disease control, especially in intensive swine farming systems with high infectious pressure. Despite being very vulnerable, newborn piglets are not commonly vaccinated because most vaccines are susceptible to...

Assessment of the replication of Porcine Reproductive and Respiratory Syndrome modified live virus attenuated vaccines in porcine alveolar macrophages

The method of attenuation influences the properties of modified live virus (MLV) vaccines. PRRSV is typically attenuated on simian cells, but a new vaccine, Suvaxyn PRRS MLV (vaccine S), was attenuated on a hamster-origin engineered cell line expressing...

Effect of mass-vaccinating sows with attenuated PRRSV vaccine on the PRRS status of breeding herds

Vaccinating sows with modified live PRRS virus vaccines (MLV) may result in transient shedding of the vaccine’s virus, which has the potential to be transmitted to their offspring. Therefore, sow mass vaccination (SMV) programs may affect PRRS status of...
