Recommendation schedule for sheep vaccination in Kenya (Narok and Kajiado)
The timetable for vaccinating your sheep depends on your region and the diseases prevalent in your area. It also depends on the animal’s age and use. Your veterinarian can help you devise the best vaccination schedule. Even if you give your vaccinations for your livestock, always follow your vet recommendations.
No matter where you live or the age of your sheep you should vaccinate your flock regularly for tetanus and two types of enterotoxaemia, commonly called overeating disease. The three in one vaccine known as CD-T provide protection against these potentially fatal ailments caused by clostridium bacteria. Lambs must receive this vaccine within a few days of birth as overeating disease is a leading cause of death in lambs. They need another CD-T shot a few months later, at weaning.
There are 4 main types of vaccines;
- Live-attenuated vaccines
- Inactivated vaccines
- Subunit, recombinant, polysaccharide, and conjugate vaccines
- Toxoid vaccines
