Be Sure You Have The Right Strategy

Work with your herd's veterinarian to find the best vaccination strategy for your operation.

• Producing the negative weaned pig — Start addressing influenza at the top of the production system. Pre-wean pigs have been shown to harbor IAV-S and can carry it to the nursery after weaning.¹
• Whole breeding herd vaccination — If animals continue to be chronically infected, this strategy helps shut down continuous viral shedding.²
• Pre-farrow vaccination — This strategy can help protect newborn piglets by increasing influenza maternally derived antibodies (MDA) transferred from the mother after colostrum intake.³
• Gilt vaccination — Immunizing incoming gilts is critical to maintaining stability in the sow herd.

Producing The Negative Weaned Pig

While pigs of all ages can be infected by IAV-S, weaning-age pigs are an important subpopulation for infection.¹

Pre-farrowing vaccination is a studied strategy that:

• Helps protect suckling and growing pigs from IAV-S.²
• Induces maternal antibodies in piglets, helping provide them with early immunity.²
• Pre-wean pigs have been shown to harbor IAV-S and can carry it to the nursery after weaning.⁴
• In a 2,000-sow farrow-to-wean farm, up to 63% of pigs* were infected with IAV-S at weaning even though there was no detectable disease in breeding-age pigs.⁵
• IAV-S mantained longer than expected in growing pig populations, for up to 70 days in a finisher pig population.⁴

*Aged 11 days and older

Whole Breeding Herd Vaccination

Whole herd or mass vaccination is a common strategy on many U.S. farms, along with pre-farrow and pre-breeding vaccination.²

A whole breeding herd vaccination strategy with FluSure XP^®:

• Might be the best strategy if animals continue to be chronically infected — it helps shut down continuous viral shedding²
• Should be administered as a two-dose blanket vaccination with semiannual revaccinations after the initial two doses²
• Must be accompanied by biosecurity control and isolation measures, as well as strategic gilt immunization and entry procedures²

See the results two swine operations had using this vaccination strategy.

Pre-Farrow Vaccination

Vaccines can help protect newborn piglets by increasing influenza maternally derived antibodies (MDA) transferred from the mother after colostrum intake.³

• Higher antibody titers were found in piglets born to sows vaccinated before farrowing compared with those of unvaccinated sows.²
• MDA can protect the piglet for eight to 10 weeks after birth.²

A pre-farrow vaccination strategy with FluSure XP:

• Helps decrease viral shedding at farrowing²
• Induces piglet maternal antibodies, helping strengthen early immunity²
• Should be administered as a single dose (as a booster in previously vaccinated animals) two to four weeks pre-farrowing²
• Helps provide higher levels of maternal antibodies when administered as a two-dose regimen²

Gilt Vaccination

Failure to properly vaccinate gilts can lead to ongoing circulation of influenza in the sow herd.

A gilt vaccination strategy with FluSure XP:

1. Includes two doses of FluSure XP beginning at age 11 to 14 weeks
2. Shots triggered three weeks apart
3. Can be administered prior to breeding with FluSure XP/FarrowSure^® GOLD or
   FluSure XP/FarrowSure GOLD B
4. Can be administered in combination with RespiSure^®, RespiSure-ONE^® or
   ER Bac^® Plus as part of complete gilt immunization protocol
