if we get a flu vaccine, will my child no longer get sick often?

Dear parents!
Recently, many have asked the question "if we get a flu vaccine, will my child no longer get sick often?"
I want to inform you that in nature there are a lot of airborne viruses that cause flu-like symptoms, such as nasal congestion, cough, nasal discharge, fever, chills, apathy, malaise, pain throughout the body and etc. Among them are viruses such as, adenoviruses, parainfluenzal viruses, respiratory syncytial virus, rhinoviruses, ECHO viruses, coksaki viruses, Epstein-Barr virus, etc.

In addition, most of these viruses have different strains with different antigenic characteristics. This means if you have had a single strain, even temporarily, but you only develop immunity to this strain. For example, if you have been ill with strain A of a virus, you will become immune to this strain, and this immunity will not protect you from infection with strain B.

Take the flu vaccine. This vaccine is a trivalent vaccine, and it develops immunity to two strains of influenza A — h1n1 and h3n2 — and one strain of influenza B virus. Quadrant vaccines against influenza act according to the same principle, but additionally demonstrate high efficacy against the influenza B strain. as mentioned above, the flu vaccine only protects you against the influenza virus and not against other influenza-like viruses. In addition, not from all of its strains (there are a lot of them), but from only H1N1, H3N2 and one strain of influenza B. In the case of an epidemic of the H1N1 or H3N2 influenza virus, it will definitely help, and if another virus is the cause of the epidemic that will not help.
So, if you think that, after this vaccination, your child will no longer have an acute respiratory illness - then you are deeply mistaken.
