Introduction
In recent years, influenza vaccines have received more and more attention from people, but some doctors do not recommend taking influenza vaccines. So why? Next we will discuss this issue from two aspects: the effectiveness and safety of influenza vaccines.
Effects
First, let’s look at the effectiveness of the flu vaccine. There are many types of influenza vaccines, and each year\’s vaccine needs to be adjusted according to the mutation of the influenza virus that year. However, because the virus mutates very quickly, the effectiveness of the vaccine is difficult to guarantee. In fact, according to historical data, the effectiveness of influenza vaccines ranges from 30% to 70%, and some viruses are not covered at all. Therefore, even if you get the flu vaccine, you cannot completely prevent infection with the flu virus.
In addition, the effectiveness of the influenza vaccine is also affected by individual differences. For example, the immune system of the elderly and children is weak, and the effectiveness of the vaccine is also limited. In addition, for some people, getting the flu vaccine may cause allergic reactions and other adverse reactions.
Security aspects
Second, let’s look at the safety of the flu vaccine. Influenza vaccine is either a live vaccine or an inactivated vaccine, with live vaccines more likely to cause adverse reactions. For example, after vaccination, uncomfortable symptoms such as fever, local pain, redness, swelling, and rash may occur, and may even cause neurological complications such as myasthenia gravis, poliomyelitis, etc. In addition, for some people, such as pregnant women and asthma patients, influenza vaccination may cause adverse reactions and even affect the fetus or airway conditions.
Natural immunity
In addition to the above factors, there is another issue worth noting, that is, the body’s own immunity. The human body\’s own immune system is very strong. As long as you stay healthy, you may not get the flu when you are exposed to the flu virus. According to research, the human immune system\’s defense mechanism against influenza viruses is more effective than vaccines. Therefore, as long as you maintain good living habits, such as washing hands frequently, exercising, eating healthily, etc., you can enhance your body\’s immunity and effectively prevent influenza.
Suggestions and Summary
Although there are certain risks and uncertainties in getting the flu vaccine, in certain circumstances, such as the elderly, children, patients with chronic diseases, etc., it is recommended to get vaccinated to prevent the occurrence of serious complications. In addition, maintaining good living habits, enhancing one\’s own immunity, and avoiding contact with sick people are also important measures to prevent influenza.
To sum up, doctors do not recommend blindly taking the flu vaccine. Analysis and judgment are required based on individual circumstances. At the same time, maintaining good living habits and improving one\’s own immunity are also important ways to effectively prevent influenza.
