A single 2ml dose is given by subcutaneous or intramuscular injection to all classes of cattle. For practicality, subcutaneous injection is recommended – The mineral oil adjuvant acts as a depot at the local and regional lymph nodes – Prolonged antigenic exposure stimulates a primary and secondary response with one injection, so a secondary booster vaccination is not required. Inject into the side of the anterior third of the neck. Animals should be vaccinated 3-6 weeks before the onset of the expected pinkeye season. Calves as young as 1 week of age can be vaccinated
