The subject is now very much discussed. The New York Times has recently published several articles on the subject. On 15 February, their science and disease prevention correspondent Gina Kolata wrote that covid-type diseases, especially some types of influenza or flu, have spread several times in the last one hundred and fifty years in different countries of the world. Then slowly gone. But it has been seen to come back after 20-30 years. Now the United States and some cold countries have to take the flu vaccine every year. Because the resistance gradually decreases. Studies in the United Kingdom have shown that the incidence of the common cold, whooping cough-type coronavirus, decreases in about a year. That's the problem.
Virus experts say that the immune system that develops after vaccination depends on a number of factors, including how long it will last. If the virus spreads rapidly and changes its variant frequently, it is difficult to develop effective vaccines in the long run. This is because the virus acquires some new features due to new types, which require the creation of new immunity to prevent it. However, if vaccinated, a new type of covid infection occurs, but its severity does not increase. Maybe there are some minor symptoms. But older people and patients with kidney, liver, hypertension or diabetes are at higher risk. Even after being vaccinated, many of them can be infected with the new type of covid and can suffer serious consequences.
The smallpox, measles or polio virus variants are almost stable, and the vaccine provides long-lasting immunity to the body. So once vaccinated in these cases, vaccination may not be needed for many years. But in the case of Kovid, the type changes rapidly. As a result, he may have to be vaccinated for at least several more days.
When Kovid is infected or vaccinated, antibodies are made in the body. In addition, the vaccine strengthens B-cells and T-cells. Later, when infected, the virus can be detected by B-cells and activates rapid resistance. These are basically memory-capable cells. When antibodies have a problem preventing the disease, T-cells come forward and flush out the infected and damaged body cells.
At present amicron type covid is capable of causing rapid transmission. As a result, more people are being attacked in a very short time. Since its severity is low, many people recover within five to seven days after a slight cold. In this situation, the World Health Organization says that if it is possible to vaccinate everyone, covid could be eradicated by 2022. However, the use of masks, avoiding public gatherings, washing hands with soap and water from time to time should be followed. Then maybe you don't have to take booster dose anymore.
Besides, it should be kept in mind that nutritious food including vegetables, fish, meat and fruits should be eaten as much as possible. Physical labor is very necessary. Those who have to work sitting in the office, walking is almost non-existent, they need to exercise regularly. If there is a lack of time, 15-20 minutes of exercise every day also gives many benefits. What exercises to do? Very easy. Inhale and exhale slowly for five minutes. For five minutes move all the limbs of the body, especially the wrists, elbows, neck, legs, knees, that is, all the joints. It is also necessary to rotate the eyeballs from side to side. Light race for the remaining five minutes. It is possible to keep the body fit throughout the year if it becomes a habit. Scientists have found that exercise increases blood circulation in the body. The alveoli of the lungs remain active. Therefore, covid virus cannot easily infect lung cells. In addition, new neurons are formed in the brain. As a result, the body is always fresh and active.
