What is the most effective injection to improve immunity

First of all, let's pour some real cold water on this - there is no so-called "most effective" immunity-boosting injection suitable for all people. All injections that promote broad-spectrum immunity improvement are either extremely narrow in indication and only targeted at specific patients, or they are marketing gimmicks to harvest IQ taxes.

I have been working as a general nurse in a community hospital for almost 8 years. Every autumn and winter, I encounter dozens of people asking if they can get a few injections to improve their immunity, so as to avoid catching colds and flu during the change of seasons. It was even more exaggerated at the peak of the COVID-19 epidemic at the end of last year. Many people stood in front of the pharmacy with cash and asked for intravenous human immunoglobulin. They said that scalpers outside were willing to buy it for thousands of dollars a bottle. But in fact, we were only prescribing blood products like G-globulin on demand to severe COVID-19 patients in the ICU, children with congenital gammaglobulin deficiency, and patients in the acute stage of autoimmune diseases. Ordinary people would not be able to prevent infection at all. Instead, they might trigger rashes and allergic reactions. Even regular products that have undergone multiple rounds of screening have a very low risk of spreading blood-borne diseases. There is absolutely no need to take this risk.

There are also thymosin peptide preparations such as thymosin and thymopentin, which are touted as "immune miracle shots" by many micro-businessmen, and they are not something ordinary people can take casually. We usually prescribe this kind of injections to patients who are immunosuppressed after tumor radiotherapy and chemotherapy, or to people with low immunity due to long-term glucocorticoid consumption. The treatment period is only 1 to 3 months at most. Healthy people have normal thymus secretion function. Extra supplementation with these exogenous peptides will "flatten" the thymus secretion function, which will disrupt the immune balance in the long run. Two years ago, I met a 32-year-old young man. I heard from a WeChat businessman that taking thymosin can reduce acne and prevent colds all year round. I privately found a channel to take it for half a year. In the end, he broke out in urticaria repeatedly. After a lot of research, it was found that the cause was an immune disorder caused by exogenous supplementation.

If we really want to be more honest about whether injections can actually improve immunity, the vaccine that everyone hears about every day is the most reliable choice. For example, the elderly at home should receive influenza vaccine and 23-valent pneumonia vaccine every autumn, the herpes zoster vaccine should be vaccinated as early as possible for those over 50 years old, and the HPV vaccine should be vaccinated for women of the right age as needed. These have been clinically proven for decades and can enable the body to produce corresponding antibodies in a targeted manner, which can actually improve the resistance to specific pathogens. The cost-effectiveness is much higher than those "magic shots" that often cost thousands or tens of thousands.

Nowadays, many high-end medical aesthetics and private institutions are promoting projects such as immune cell reinfusion and stem cell reinfusion, claiming that one injection can prevent you from getting sick for three to five years. Research on this type of technology has indeed been ongoing, and it also has certain auxiliary treatment value for some refractory autoimmune diseases and advanced tumors. However, there are currently no relevant indications approved for ordinary healthy people in China. , most of the injections available on the market are in a gray area, and the effect is uncertain. There are also cases of severe allergies and immune storms after infusion. A while ago, a 40-year-old sister came to our hospital for treatment. She said that she spent more than 60,000 yuan on a so-called NK cell infusion, and she had a fever for 4 days. After that, she still had a cold when the season changed, and the money was completely wasted.

In fact, for most healthy people who have no underlying diseases and have a fairly regular schedule, there is really no need to rely on injections to improve immunity. Sleep enough for 7 hours a day, take a walk for half an hour three or four days a week, and eat less takeaways that are heavy in oil and salt. If you stick to these three things for three months, you will find that it is more effective than any injection. If you really feel that you get sick easily and your immunity is low, you should first find a doctor to check if there are any hidden underlying diseases. Don’t just look for random channels to get injections, which will cause trouble for your body.
