MetaStim Adjuvant Added to Swine Vaccine

A reformulated Zoetis vaccine fights porcine circovirus.

Fostera PCV MetaStim is made by Zoetis Inc.

Zoetis Inc. has released a reformulated porcine circovirus (PCV) vaccine that includes the MetaStim adjuvant.

MetaStim, a common vaccine emulsion, slows the release of antigens, giving a pig’s immune system more time to respond to the virus, the company reported today.

“MetaStim has been used in swine, bovine and equine vaccines for years, including most recently, Fostera PCV MH,” said Darrell Neuberger, DVM, of Zoetis’ Pork Technical Services.

The new Fostera PCV MetaStim swine vaccine is indicated to protect against diseases caused by porcine circovirus Type 2 (PCV2).

The vaccine carries 23-week duration of immunity, the Florham Park, N.J., company stated.

Fostera PCV MetaStim, which replaces Fostera PCV, is available in 50- and 250-dose vials.
