Merck Animal Health has introduced the first porcine circovirus Type 2 (PCV2) vaccine, Circumvent PCV G2, for use in pigs as early as 3 days of age in a one- or two-dose formulation. The vaccine offers five-month duration of immunity (DOI), which the company claims is at least 25% longer than any other PCV2 vaccine on the market. "Vaccines with longer DOI can provide better protection and potentially reduce mortality just prior to marketing, where the loss of a pig approaches market value," says Derald Holtkamp, DVM, Iowa State University. "In a barn of 1,000 pigs, if just one, 270-lb. pig is saved, and carcass prices are at $1 per pound, the benefit is more than $200 or $.20 per pig."
