What is immunoglobulin for children?

Many children need to get a vaccine - immunoglobulin when they are young because their immune system is not yet fully developed. Prone to illness. Especially those with poor physical condition. When the seasons change or the weather changes. Most likely to catch a cold and have a fever. Therefore, when children are young, they are given immunoglobulin. To enhance immunity. However, many parents are not clear about what immune protein is. Let me explain the composition of immune protein.

Immunoglobulin is a large Y-shaped protein secreted by B lymphocytes and used by the immune system to identify and neutralize foreign substances such as bacteria and viruses. It is only found in the blood and other body fluids of vertebrates and on the cell membrane surface of their B cells. Most of the immunoglobulins in human plasma are present in gamma globulin (γ-globulin). Immunoglobulins can be divided into five categories: IgG, IgA, IgM, IgD, and IgE.

1. The immunity produced after immunoglobulin G is injected into the human body is given passively, not actively produced by the body. It is generally excreted within 2 weeks, after which the immunoglobulin G content in the body returns to its original level. To maintain a high level of immunoglobulin G in the body for a long time, it must be injected once every 2 weeks.

2. The use of immunoglobulin has certain indications because the preventive effect of this drug varies depending on the amount of antibodies it contains. Ordinary immunoglobulin G is mainly used to prevent measles, hepatitis A, mumps, etc. It is impossible to use immunoglobulin G to prevent various diseases.

3. If immunoglobulin is injected repeatedly, it can act as an antigen to stimulate the human body to produce an antibody against immunoglobulin G, namely anti-antibody. Once immunoglobulin G is injected again, it will be neutralized by the antibody and cannot play its anti-disease effect.

4. The human body can synthesize immunoglobulin G by itself. If foreign drugs are used frequently, it will inhibit the production of autoantibodies, thereby reducing the body's disease resistance.

5. Since immunoglobulin G is a blood product, if the source is not strictly controlled, it may cause blood contamination and infect healthy people with diseases. Moreover, to the human body, foreign immunoglobulin G is a "foreign body" after all, and some individuals may have allergic reactions after injection.

Therefore, there is no scientific basis for using immunoglobulin G as a fortifier or tonic, and it is impossible to prevent diseases and enhance physical fitness in the long term by repeated injections of this drug.

In fact, in addition to injecting immunoglobulin, there are other ways to improve children's immunity. For example, take your children out to bask in the sun more often. The diet should be reasonably matched, the nutrition should be balanced, and the children will not be picky eaters. Maintain a regular work and rest schedule. Ensuring that children get enough sleep can increase their resistance.
