Introducing The 4 Way Horse Vaccine

In recent years, vaccines have hit the headlines, sometimes for all the wrong reasons. However, most of us get our horses vaccinated without querying what is in the vaccine. But what is the 4-way horse vaccine and is it the right one for your horse?

The choice of horse vaccinations can be overwhelming! It can be difficult to know which is the right vaccine for your horse. Let’s take a look at horse vaccinations and find out what they are all about!

What Is A Vaccine?

Vaccines, or vaccinations, are injections that are given to your horse to protect them from certain diseases. They must be given at specific times and at the correct intervals for them to work properly. You may sometimes hear of vaccinations referred to as inoculations.

Vaccinations work by introducing a tiny, harmless replica or fragment of a disease-causing pathogen into the body. This causes an immune reaction in your horse, which creates antibodies that can kill this pathogen. Then, when your horse is exposed to the disease in real life, it can kill the disease-causing pathogen before infection occurs.

In horses, there is a range of different vaccines available. Which ones are given to your horse will depend on many factors, including the age and location of the horse. Whether your horse is used for breeding is also a risk factor, and the cost of the vaccine can also affect which one is used.

What Diseases Can Horses Be Vaccinated Against?

The range of different diseases which horses can be inoculated against is huge! Equine vaccinations are available for all the following diseases:

  • Tetanus
  • Equine Influenza
  • Equine Herpes Virus
  • Botulism
  • Equine Viral Arteritis
  • Equine Encephalomyelitis (Eastern & Western)
  • Rotavirus
  • West Nile Virus
  • Rabies
  • Streptococcus Equi
  • Potomac Horse Fever

As with any type of medication, vaccinations should only be given when absolutely necessary. It would be bad practice to give your horse a vaccination against diseases to which it is unlikely to be exposed.

For instance, in the United Kingdom rabies cases are incredibly rare. Therefore, horses in the UK are not vaccinated against this disease unless they are traveling abroad.

What Is The 4 Way Vaccine For Horses?

So, let’s take a look at different types of vaccines for horses. The first of these is the 4-way horse vaccine, which is one that your veterinarian may recommend to you. This vaccine gives your horse protection against four different transmissible equine diseases.

However, confusingly there are different types of 4-way horse vaccines that protect against different diseases! So, it is very important to check with your veterinarian to discuss which one is right for your horse. They will know which diseases are most prevalent in your local area.

The 4-way horse vaccine may include any combination of four of the following transmissible diseases:

  • Equine Influenza
  • West Nile Virus
  • Tetanus
  • Eastern Equine Encephalomyelitis
  • Western Equine Encephalomyelitis

Most 4-way horse vaccines will contain the last three components, with either equine influenza or West Nile virus as the fourth disease.

Why Do Horses Need The 4 Way Horse Vaccine?

It is very important to get your horse vaccinated as it will protect your horse against some very dangerous diseases. Some of these, such as tetanus, can be transmitted through soil or rusty objects, so even a horse that lives alone should be vaccinated.

Other diseases, such as equine influenza, are highly contagious. This means that they are transmitted from horse to horse very easily. Vaccination of horses prevents the spread of these diseases through the horse population.

What Is A Vaccine

If your horse is fit and healthy, it is your responsibility to get it vaccinated. This helps to contribute to something called herd immunity.

This happens when enough horses are vaccinated to stop the spread of disease. This is essential to protect vulnerable horses such as foals and elderly equines.

Is The Equine 4 Way Vaccine The Right One For Your Horse?

Whether the 4-way vaccine is the right one for your horse is something that depends on your location and other factors. For example, if you want to attend competitions and other events, you may be required to show that your horse has been vaccinated against certain diseases.

It may be that a higher or lower risk of certain diseases in your geographical area will affect your choice of vaccine. Your local veterinary clinic will be able to advise you on the most suitable vaccine for your horse.

When Is The 5 Way Shot For Horses Used?

The 5-way horse vaccination protects against all the same diseases as the 4 way shot. It also includes protection against equine herpes virus. The 5-way horse vaccination is the one most commonly administered by equine veterinary practitioners.

Which Horse Vaccinations Are Essential?

The core equine diseases that horses should be vaccinated against are tetanus, equine encephalomyelitis, and West Nile virus. All these diseases pose a threat to any horse, no matter what circumstances they live in.

Tetanus can be found in the soil and on rusty and grimy surfaces. This means that any horse can be infected with tetanus. Both equine encephalomyelitis and West Nile virus are transmitted to horses by mosquitoes.

The name of a vaccine simply tells you how many diseases are being vaccinated against. You need to know which diseases are being prevented, whether it is a 4-way, 5 way, or even a 6-way vaccine. Don’t assume that just because it covers a lot of diseases that it will protect your horse against the core ones!

Summary

So, as we have learned, a 4-way horse vaccine gives your horse immunity against four diseases. This will normally include eastern and western equine encephalomyelitis, tetanus, and either West Nile virus or equine influenza. This vaccination is not given as commonly as the 5-way horse vaccine, which also gives protection against equine herpes virus.
