What kind of injection can boost immunity?

There are many ways to boost the immune system, and injections are one effective method. First, the most common type is vitamin B complex injections. The B vitamins are essential components of the immune system, and deficiencies may reduce the body's immunity. Another option is injecting human immunoglobulin, which not only activates cellular immune mechanisms but also directly combats viruses, thereby enhancing immunity. Additionally, injections containing active ingredients from traditional Chinese medicine can help resist external viruses and strengthen the body’s immune function. Finally, injections of essence extracts can support and enhance the immune system, offering better protection against viral infections. In summary, injections can improve immunity, but due to various individual factors, no single injection suits everyone. Before undergoing treatment, patients are advised to consult a doctor to ensure the selected injection formula is optimal.
