The working principle of vaccines


The principle of operation of all vaccines is this - they contain a weakened or "killed" infectious agent or its particle, which safely familiarizes our immune system with the threat and teaches it how to destroy it. When we encounter a real infection, our immunity is already ready to protect us from it.

For the human body, it makes no difference how it gets acquainted with pathogens - in several separate monocomponent vaccines or as part of one multicomponent vaccine. The result will be the same - we will have protection against these infections.

However, there is still a difference between mono- and polyvaccines. It consists in the number of injections.

At 2 months, for example, a child should be vaccinated against six infections: whooping cough, diphtheria, tetanus, hepatitis B, HIV infection and poliomyelitis. If they are made as separate vaccines, it will be four shots: monovaccine for hepatitis B, monovaccine for HIV infection, monovaccine for poliomyelitis and combined vaccine for whooping cough, diphtheria and tetanus. And you can inject one six-component vaccine, which will protect against all these infections, or one five-component and one monocomponent vaccine.

All these options will provide exactly the same protection. But for a small child, each injection is additional stress. Therefore, if you have a choice, you can give preference to a multicomponent vaccine. If there is no such choice, it is worth vaccinating the child with those vaccines that are available.

In times of war, protection against infectious diseases is especially important. It is better to give your child several vaccines on time than to leave him unprotected while you wait for the right multi-component vaccine.
