Vaccines to Farm Animals

How to Properly Administer Vaccines to Farm Animals.

Quite surprisingly, a customer once said that vaccines should not be administered to farm animals reared for consumption as they could harm humans. This article has been created to help you better understand vaccination, the role it plays in animal husbandry, and how to properly administer vaccines. Just like humans need medical care and are encouraged to visit their doctor, farm animals also frequently need the same care and attention considering their fragile nature. Also, their inability to communicate verbally makes it impossible to know when they are sick except you are observant enough to notice a change in their behaviour or general performance. Vaccines limit the spread of infectious diseases from animal to animal and animal to humans while ensuring that farm produces are healthy and safe for consumption. Before vaccinations are made available or commercialised, they pass through a series of tests to prove their potency, safety, and efficacy. 

Farm Animals suffer from diseases caused by pathogens which usually leads to their death if they are not immediately attended to. Apart from the death of farm animals which could result to scarcity and hike in the prices of both the animal and their products, like meat, milk, or eggs, the outbreak of a disease in a particular farm could lead to national or global crises. Without the use of vaccination, animals will not be able to live fully and enjoy a healthy and productive life. It’s a good time to also inform you that the consumption of vaccinated farm animals does not have any negative effect on humans. 

Tips for Administering Vaccines to Farm Animals. 

Being a successful farmer doesn’t qualify you to diagnose sick animals or administer their vaccine. Once you have noticed a shift in the performance of an animal, it is important to immediately invite a veterinarian to have a close examination of the affected animals.

Vaccine Administration

When it comes to the administration of vaccines to farm animals, you should go through proper training before you perform such duty or simply call on trained personnel for assistance. Furthermore, the vaccine should be administered in the right part of the animal’s body, in the right proportion and time of the day. The amount of vaccine to be administered on a regular basis should be in accordance with the advice of your veterinarian as their dosage is dependent on the level of risk the animal is faced with. 


To prevent the further spread of diseases and bacteria, needles should be used with great care when administering vaccines to farm animals. A new needle should be used frequently, let’s say after every 8 -10 animals; needles should also be disposed of properly and a single needle shouldn’t be used to administer separate injections. It’s not strange for needles to break during vaccination. Do not be nonchalant if this occurs, instead, mark the area of the animal’s body where the needle has broken in, then seek medical attention to get it removed. However, such an incident can be avoided by being extra careful, making use of the right size of a needle, and changing a needle immediately it gets bent. Positioning animals properly to reduce their movement while administering vaccines could also prevent the needle from getting broken.


Documentation is an important aspect of the vaccination process and should be done religiously. I bet you don’t want to administer the wrong drugs to a group of animals or mix up the vaccine administration date. Create a system that helps you record information about your animals like their identity number, breed, disease type, vaccine, administration procedure and dosage, along with other important details. While the vaccination process is ongoing, ensure you make a mark on animals that have already been administered their drugs and put them in a separate area to prevent them from interacting with the rest else the effectiveness of the vaccine can be reduced.


Storing vaccines wrongly could make them less effective, therefore, they should be stored in a cool temperature according to the manufacture’s recommendation; if they have been removed from their pack, they should be properly labelled. The storage of vaccines is the duty of all parties including the manufacturers, distributors, and administration staff.
