Intramuscular injection generally has two types, one is hip injection and the other is deltoid injection of the arm. Why were you chosen these two places to get vaccinated? First of all, we need to understand the formation process of human immune .

When human immune cells encounter antigen introduced by the vaccine (including a small number of viruses and bacteria), the antigen will be delivered to our lymphatic vessels. After the lymphatic vessels encounter immune cells carrying antigens, they will be further passed to lymph nodes . Lymph nodes are an important part of the human immune system and contain more immune cells. When lymph nodes receive antigen information carried by immune cells, they will generate an immune response and produce antibodies. This process is the immune process. Therefore, when vaccinating, in order to better deliver antigens, areas containing immune cells and close to lymph node clusters must be selected.
human muscle tissue contains important human immune cells. The common intramuscular injection area includes the deltoid muscle area of the upper arm, which is close to the lymph nodes under our armpits; and the buttock area, which is closer to the lymph node clusters of inguinal . In addition, the muscles in these two places are relatively thick, and it is not easy to damage the bones and deep blood vessels when inserted into the needle.
