The vaccine course should be completed at least 2 weeks before maximum immunity is required i.e., a risk period, or in pregnant ewes during lambing.
Previously sensitised ewes should be injected 2 to 6 weeks before lambing is due to commence. This provides passive protection of the lamb, via the colostrum, for up to
12 weeks.
Covexin® 10 may be used in lambs as young as 2 weeks of age, regardless of serum antitoxin levels acquired from maternal transfer.
- Cows and calves over 2 weeks of age
Two injections of 2 mℓ each, at an interval of 6 weeks, and a booster annually thereafter.
Previously sensitised cows should be injected 2 to 6 weeks before calving is due to commence. This provides passive protection of the calf, via the colostrum, for up to
12 weeks.
Covexin® 10 may be used in calves as young as 2 weeks of age, regardless of serum antitoxin levels acquired from maternal transfer.
