Merck Cattle Vaccines

Merck Animal Health has just introduced Nasalgen 3, a three-way intranasal vaccine that protects beef and dairy cattle from the most common pneumonia-causing viral pathogens. Administering intranasal vaccines to neonatal calves is considered one of the most effective strategies to put protective immunity in place quickly and establish a strong foundation for future respiratory protection. Nasal administration generally isn’t considered to be affected by maternal antibodies.

Merck says Nasalgen 3 has the longest six-and-a-half-month duration of immunity (DOI) against infectious bovine rhinotracheitis (IBR), an 11-week DOI against bovine respiratory syncytial virus (BRSV) and a three-month DOI against parainfluenza 3 (PI3). “Nasalgen 3 mimics natural exposure to the most common pneumonia viruses,” says Scott Nordstrom, D.V.M., associate director of ruminant life cycle management, Merck Animal Health. “The intranasal administration of Nasalgen 3 stimulates a strong, early immune response because the vaccine antigens are delivered to mucosal surfaces in the nose – an area loaded with immunologically active tissues.”

Nasalgen intranasal vaccines avoid interference from maternal antibodies in colostrum that can block injectable vaccines and are less stressful on calves compared to similar injectable vaccinations. Nasalgen 3 also is designed with an IBR that is not temperature-sensitive, so the vaccine will replicate and protect in a moderate to high temperature environment, Merck says.

Description

Merck Animal Health has announced that Bovilis Nasalgen 3-PMH is now available to veterinarians and cattle producers to protect cattle from five of the most common pneumonia-causing viral and bacterial pathogens. Approved for use in dairy and beef cattle, this is the first intranasal vaccine effective in providing early, broad-spectrum respiratory protection against both viral and bacterial pathogens in a needle free, animal- and BQA-friendly administration.

     “Bovilis Nasalgen 3-PMH is a modified-live, intranasal vaccine that stimulates a strong early immune response to help give calves a strong foundation of respiratory disease protection,” says Scott Nordstrom, D.V.M., director of livestock innovation and discovery, Merck Animal Health. “Results of efficacy, duration of immunity and safety studies demonstrate the vaccine is safe and effective for calves at 1 week of age or older.  The vaccine protects against infectious bovine rhinotracheitis (IBR), bovine respiratory syncytial virus (BRSV), parainfluenza 3 (PI3), Mannheimia haemolytica and Pasteurella multocida.
