Our dogs have extra support to fight diseases, and they are injections whose purpose is to create memory cells for the immune system. Do you want to know how they work?

A vaccine is made up of pathogenic microorganisms or their toxins (known as antigens ) that, by injection, will be introduced into the animal’s body. They do not pose any danger to the dog, in this case, because veterinarian has treated these organisms to be stunned or killed.

The lymphocytes are vigilant, and protective cells of the immune system are the most important charge to defend the body of invading infections.

When the substance treated by scientists enters in a dog’s body, the lymphocytes will stop the microorganisms or antigens, examine them and create antibodies against them and memory cells (the main reason we vaccinate our dogs) that will quickly recognize the virus or pathogenic organism when it enters itself on a future occasion, allowing the organism to have those to win that battle against the bad guys.

For the vaccine to be fully effective, it will have to be able to develop the immune response in our animal and at the same time, preserve the ability not to cause the disease when inoculated.

The health of our dog is protected by this method of prevention.

In certain cases, vaccines are the only remedy that can save our dog from severe illness or even death. There are diseases such as rabies that do not have an alternative prevention and if an animal suffers from it, it will not have any treatment, and you will only have to wait for the dog to die.

Therefore, follow the vaccination schedule of your best friend carefully. When they are young, the immune system is not fully mature, so it is better to start with extra help from the first months.

As they become an adult, your pet’s organism will need annual reminders to ensure that protection against such disease, because the risk remains high as the memory cells are still present and active.

Vaccinate him when he is healthy and dewormed, otherwise, he will have low defenses, and his immune system may not be strong enough to attack the disease he suffers and make many memory cells for this vaccine.
