Humans cannot stop aging, aging is inevitable. All human organs and systems are affected by aging, and the immune system is no exception.1. What happens to the immune system as people age?
As we age, do we get sick more often than when we were younger? When the weather changes, does the body immediately feel unwell? And getting back to normal also takes longer than before? This is due to the weakening of the immune system over time.
There is no organ or part of the human body that can avoid the effects of aging, but fortunately the immune system is not affected too much. Compared to other organs of the body, in most cases, the immune system can still function quite well at any age, enough to ensure that the risks from infection or disease are not exceeded. higher than normal.
The immune system has a very complex structure, consisting of many different organs, tissues and cells. The synergistic action between the components helps the immune system fight off infectious agents (such as bacteria, viruses, fungi,...).
Although less affected than other organs, but with age the immune system still weakens gradually. Medical researchers are still actively learning why the immune system declines over time and how it declines. Some questions already answered:
Why do most elderly people respond poorly to vaccines? In the human immune system there are cells called T cells, which are responsible for attacking infected cells, then remembering the pathogen so that it can fight it faster and more effectively in the future. future. As people age, fewer T cells are produced, while the response to vaccines depends on T cells, so the elderly do not respond well to vaccines. . In fact, there are exceptions, which is the case with the shingles vaccine, and that is one of the reasons why this vaccine is so effective when used in booster doses. Why do elderly people get sick more often? Not only does the number of immune cells decrease over time, the immune cells in the elderly do not work together very well, and thus the protection against pathogens is also less effective.

2. Is it possible to tell when the immune system starts to weaken?
The weakening of the immune system does not occur at a certain age, each person will occur at a different time, so there is no way to know in advance. And until now, there is no test that tells us that the immune system is not in optimal condition.
Therefore, it is very important to have regular health check-ups, and if you are sick often or find yourself recovering too slowly from illness or injury.
