Moraxella bovis vaccine is indicated for healthy cattle to help prevent or control pinkeye (infectious bovine keratoconjunctivitis (IBK)), caused by M. bovis.

INDICATIONS

• Prevention of Pinkeye (IBK): The primary use is to protect cattle from the clinical signs of pinkeye, like corneal opacity, ulcers, tearing, and redness.
• Herds with History of Pinkeye: Recommended for herds experiencing recurrent pinkeye outbreaks.
• Age: For healthy cattle, typically starting from 2 months (8 weeks) or 3 months of age, with some vaccines targeting older calves (e.g., 14 weeks).
• Specific Strains: Vaccines often contain multiple M. bovis isolates to broaden protection, though effectiveness can vary with circulating strains. 

ADMINISTRATION

• Dosage: A single 2 mL dose is administered per animal.
• Method: The vaccine is to be injected subcutaneously (under the skin).
• Timing: It should be given prior to the expected onset of the pinkeye season.
• Age: The vaccine is safe for use in cattle 2 months of age or older.
• Revaccination: A 2 mL booster dose is recommended annually before pinkeye season to maintain immunity.
• Adverse Reactions: Anaphylactoid (allergic) reactions may occur. Epinephrine is the antidote.
