It is a substance that has been manufactured in the laboratory and used to stimulate the immune system to produce antibodies to immunize the body against disease or several diseases. Injecting this agent into the cat/dog’s body. This stimulates the body’s immune system, allowing it to recognize it as a threat and resist it. After that, it is usually immune to this disease, so that if the animal’s body faces the same disease in the future, the immune system is ready to fight it and escape from it, God willing. It usually takes about 7-14 days for the body to respond and boost immunity.

How do vaccinations work?

When an animal is born, its immune system contains all the components found in the immune system of an adult animal, except that it is considered naive, meaning it has never been exposed to any infection before, so if such an animal is exposed to infectious diseases while it is not immunized, it may take two weeks for symptoms to appear ( The immunity is fighting the infection with its defensive response. As for treatment (with the help of certain antibiotics and rehydration solutions), it may take 10 days or more and it may or may not survive it. We may not even notice he has it.

When an animal is vaccinated, the veterinarian injects a small amount of a virus or bacteria (or other infectious agents) under the skin. A Modified Live Virus or an inactive type killed vaccine from a virus or disease-causing bacteria so that the body has immunity to it and recognizes it while it is in good health so that if it is exposed to the same virus or bacteria in the future, the probability of its ability to resist and survive it increases, God willing. But just vaccinating a cat/dog does not guarantee 100% immunization and we will discuss that shortly.

Here we will mention how to stimulate the immune system to have a protective response against infectious organisms, and let's get acquainted with the components of the immune system of living organisms:

1. Antigen

A protein or sugar on the surface of an infectious cell, foreign body, or organism that the immune system can recognize and decide to attack. The immune system identifies antigens as “self” (the body is familiar = not threatening) or “foreign” (the body is unfamiliar with them). = threatening), the immune system attacks only foreign antigens.

2. Lymphocytes

It is a specific line of white blood cells found in the body, of which there are two main types:

  • T lymphocytes/T cells: which determine the antigen and help the B cells to do their job
  • B lymphocytes/B cells: Once they have matured and made antibodies, they are called plasma cells, and each cell makes only one type of antibody to block a specific antigen.

T and B lymphocytes regulate immune system responses and are involved in the activation of other immune and inflammatory cells. Both T and B cells and antibodies target only the antigen foreign to the immune system. When the antibody finds a foreign antigen, it blocks its movement and then calls upon the antigens. inflammatory cells to kill it

3. Virulent

This term is used to describe an infectious organism capable of causing severe disease, especially in an unvaccinated animal.

4. Infectious organisms in the Wild-type environment

This term refers to naturally occurring viruses and bacteria in the environment, wild-type viruses and bacteria that the animal encounters in the environment and may cause infection, so we vaccinate them.

5. Types of Vaccines Vaccines

Modified Live Virus (MLV) Vaccine

It is considered an active vaccine in which the virus/bacteria that we are trying to immunize against, but it has been modified by removing the disease-causing trait, and this type is more effective, effective, and immune stimulating.

Inactive Killed Vaccine

It contains dead bacteria or viruses or parts of them that are unable to reproduce in the animal's body. Recently, rabies vaccines are mostly inactive.

Subunit Vaccines

They are small parts of organisms, certain proteins or sugars (called antigens) that the immune system recognizes as foreign to the body, a form of inactive killed vaccine

Inactive killed vaccines and subunit vaccines are generally considered to be less immune-stimulatory, meaning that they are less able to elicit an immune response and therefore the body may not benefit from them (immunization does not occur), compared to Modified Live Viruses. Additives (called adjuvants) are added to inactive killed vaccines and the like to stimulate immunity and increase the possibility of immunization.

Bactrim Vaccine

Vaccinations that are against the Bactrim vaccine (for the sake of analogy as well: fungal vaccinations) are added to stronger adjuvants to stimulate immunity to make antibodies, because often without these enhancers the immunity will not react with them, and the stronger the strength of the enhancers in the vaccination, the greater the chance of recurring symptoms Adverse reactions to the animal are higher, but the immunity to this type of vaccination is less effective and short-lived and therefore the breeder needs to re-vaccinate every 6-12 months. 

SoonThe worst thing is that it was observed in many cases of dogs who received the Bactrim vaccine against Leptospirosis Vaccine and then caused them to contract the same bacteria instead of protecting them from it, and some cases of kidney failure in older animals have also been linked to their taking this type of vaccination.


6. Is vaccinating cats/dogs dangerous for them?

Vaccination for puppies and very young cats is important, because their immune system, as we mentioned, is considered naive, so the possibility of forming an immune memory and achieving immunization is higher than when they grow up, but vaccinations may be considered dangerous in some cases, such as:

Vaccination at an inappropriate age:

It is not correct to vaccinate puppies and kittens before the age of two months, because before this age they usually take their immune bodies from the mother’s milk, and their immune system before the age of 6-8 weeks is not able to receive the vaccination material efficiently, so even if it harms them, it will not benefit them, and even at the age of two months they must Examine them and make sure that they are safe and that they do not have any disease, digestive problems or heat, and that their weight is normal and appropriate for their age and size, and then vaccination is done according to a specific course for kittens and puppies, and we do not recommend delaying childhood vaccinations at all.

It is better that we have finished the entire course of childhood vaccinations at the age of 3-4 months (we look at the courses) 

It is also not recommended to vaccinate old cats and dogs because of the risk to body functions and immunity, and we will mention in detail several opinions about when we should stop vaccinating them and why

Improper vaccination:

Vaccinating a cat/dog during his illness, where the immunity is already in an unstable situation and the body is weak and cannot tolerate vaccination and may not survive its consequences or not benefit from vaccination at all, so you should not vaccinate your cat/dog during his illness or in a period when he is tense or A period of travel or even before/after drooling for a period of two weeks as a minimum because taming damages the immune system

Warning: Vaccinations do not work as a cure for diseases, but rather as prevention of them only. If we vaccinate an infected cat/dog, the possibility of his death is great, God forbid.
