The new vaccine offers convenient one- or two-dose administration options with five-month duration of immunity (DOI), which is at least 25 per cent 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 its market value," says Derald Holtkamp, D.V.M., M.S., associate professor, Iowa State University College of Veterinary Medicine. "In a barn of 1,000 pigs, if just one 270-pound pig is saved, and carcass prices are at $1 per pound, the benefit is more than $200, or $0.20 per pig."

Merck Animal Health is focused on providing new products that get pigs off to a healthy, stronger start for a more profitable finish, as well as on responding to the changing needs of its customers.

"Whether your operation uses a one-dose vaccine protocol or you choose to vaccinate with two doses, Circumvent PCV G2 offers you convenience and the same superior efficacy you have come to expect from our Circumvent line of vaccines," says Brad Thacker, D.V.M., M.B.A., Ph.D., Merck Animal Health senior technical services veterinarian. "We are pleased that we can now offer our customers options that make their operations even more efficient and productive, and excited that this new vaccine is just the beginning of what we will be able to offer the industry in terms of PCV2 protection."

One-dose option: One 2-mL dose can be given to pigs three weeks of age or older.

Two-dose option: The initial 1-mL dose can be given to pigs as early as three days of age with the second 1-mL dose following three weeks later.

Circumvent PCV G2 aids in the prevention of PCV2 viraemia, which helps stop infection early in the disease process before tissue damage can occur. This in turn helps reduce the risk of co-infection from porcine reproductive and respiratory syndrome virus (PRRSv), Mycoplasma hyopneumoniae and swine influenza virus (SIV) because the immune system is not compromised. This vaccine also aids in the reduction of virus shedding and lymphoid infection.
