Dose

Notes on Immunity 

Active immunity – vaccination stimulates the immune system to produce antibodies which are detectable, within 10-14 days. To stimulate adequate protection in previously unvaccinated animals, a second dose should be given 4-6 weeks after the first. The first or sensitising dose primes the immune system and results in a relatively low, shorter-duration immunity. The second or booster dose results in a higher level of protection lasting for a year. After the second dose is given, it is then necessary to give only one dose, 2-4 weeks prior to lambing as an annual booster to provide strong, long-lasting immunity. 

Passive immunity – the transfer of protective antibodies from the ewe to the lamb via the colostrum. When the ewe is vaccinated 2-4 weeks prior to lambing the high level of immunity developed allows the passive transfer of antibodies during suckling. This protection lasts 3-4 months.
