What is immunity?
Immunity (Latin of immunitas — release, disposal of
something) is an ability of immune system to struggle with the most different,
alien objects for an organism: viruses, bacteria, toxic agents of a vegetable
or animal origin, the elementary microorganisms, mushrooms, allergens. Besides,
"strangers" also own cells of the person which underwent changes
for one reason or another, for example, cancer admit.
Recognition of "enemies" or, scientifically,
anti-genes happens at the gene level. The immune system constantly analyzes
genetic information of each cage which got to an organism or changed in it. If
this information does not correspond to put, protective mechanisms turn on. For
fight against each type of an anti-gene own specific antibodies are developed –
they liquidate alien objects and help an organism to cope with a disease.
Bodies of immune system of the person
If you want that your child was healthy, pay special
attention to bodies of its immune system. You see what important role is
played, for example, in it by a gastrointestinal tract: intestines and liver?
Features of immunity at children
The immunity (acquired) of each person is formed for
long years, since the birth. Experts allocate five main critical periods:
First 28 days of life of the child
During this period children's immunity – what is
received by the kid from mother to birth, so, the probability to catch an
infection against which it is not protected by maternal antibodies is high. The
most important factor of protection of health at this age is breastfeeding.
4-6 months
Usually, approximately by 6 months babies completely
lose maternal immunity. For formation of own immunity it is time to begin
vaccination against the most dangerous infections.
2 years
The kid begins to learn actively the outside world and
constantly faces the unfamiliar infectious environment including with new
anti-genes. The number of contacts with adults, children, perhaps, pets
increases. It is not necessary to limit the child in it, trying to protect from
possible diseases, naturally, all well moderately and under your vigilant
supervision including behind immunity of the kid. Its immunity from it will
only become stronger if preventive actions are picked correctly up and
balanced. Diseases will not follow a train any more, continuously one behind
another, and after everyone need will not recover and restore up to the end
immunity!
4-6 years
At this age the child already has saved up (some
acquired) an immunity which was created as a result of vaccination and various
postponed diseases. At most of children – behind the first, most difficult year
spent in kindergarten. We hope that you managed to avoid formation of many
chronic diseases and it will not happen in the future. The special attention
should be paid to timely, correct treatment, final recovery and a complete
recovery of an organism after ORZ and a SARS.
12-15 years
During the teenage period and hormonal reorganization the volume of
lymphoid bodies decreases. During this period types of the immune answer are
finally formed, and the child closely approaches adulthood with that baggage of
health which you together with it did not spend, and could save up for all
these years.
