Vaccine innovation helps swine producers stay ahead of PCV2

Since emerging as a major pathogen 20 years ago, porcine circovirus type 2 (PCV2) has become a fact of life for swine producers. “Virtually every farm is infected,” says Dr. James “Jamie” Lehman, DVM, MS, swine technical services veterinarian for Merck Animal Health. “It’s just a challenge of managing your immunity both in the sow herd and among your piglets.”

A large part of Dr. Lehman’s job is working with producers and veterinarians to troubleshoot PCV2 health problems. He sees pigs with PCV2 infections exhibiting poor growth rates, lethargy and skin lesions.1 Understanding the dynamics of each herd helps Merck Animal Health recommend PCV2 vaccine protocols that create the most positive outcome.

“We support customers with diagnostic plans and herd visits as needed, getting to know the operation and help plan the investigation.” Dr. Lehman says. “Every case is different, depending on the age of pig affected.”
