INFORCE 3® was the first commercially available intranasal respiratory vaccine that helps protect against respiratory disease caused by BRSV, while also protecting against IBR and PI3, to help get cattle off to a healthier, more productive start.

INFORCE 3 has seen continued improvements since approval in 2010, including a six-month duration of immunity claim for IBR protection, and a single-nostril administration claim. Additional research also demonstrated no maternal antibody interference for IBR and BRSV.

INFORCE 3® is safe for use in all types, ages and classes of cattle. INFORCE 3 was demonstrated safe for use in very young calves; high-stress calves; weaned and high-stress stocker calves; recently calved cows; and pregnant heifers and cows.
