Another tool in the PRRS-management toolbox
The United States Department of Agriculture has approved the use of Ingelvac PRRS MLV vaccine for whole-herd (boars excluded) vaccination in PRRS-positive herds. This new product claim provides you with another much needed management tool to help achieve a simultaneous and high level of immunity for the whole herd when dealing with the impact of PRRS. Whole-herd vaccination has been proven safe and effective in pigs, gilts and sows at any stage of production in PRRS-positive herds.
“The strategic objective of whole-herd vaccination in PRRS-positive herds is to eliminate any naïve sub-populations within a herd,” says Reid Philips, manager of swine respiratory technical services for Boehringer Ingelheim Vetmedica. “This is important since field strains of the PRRS virus can persist and appear to spread more readily and chronically circulate when carrier pigs shed virus to sub-populations of naïve pigs in the same population.
This new claim provides the whole sow herd with immunization without inducing disease.”
The claim also gives swine practitioners another tool in their toolbox to significantly reduce reproductive failure and respiratory disease due to the PRRS virus.
According to Tom Gillespie, Rensselaer Swine Services, in Rensselaer, Ind., “A whole-herd ‘double mass’ vaccination strategy has proven to be very effective in stabilizing acute or chronic herds compared to traditional vaccine strategies.” Based on experience with whole-herd immunization, he recommends vaccinating the entire female breeding herd with Ingelvac PRRS MLV twice — 30 days apart — and then following with a single vaccination of the entire female breeding herd again on a quarterly basis.
Ingelvac PRRS MLV is proven safe in pigs as well as gilts and sows at any stage of production in PRRS-positive herds. It provides cross protection against heterologous (including Lelystad virus) and homologous challenge and has been shown to significantly reduce reproductive failure and respiratory disease due to PRRS virus.
Caution: Ingelvac PRRS MLV is not recommended for use in PRRS-naïve herds or breeding-aged boars.
