COVID-19 Vaccination: Millions of people around the world raised their sleeves to get the Corona Vaccine, but why don't they remove the pants and get their feet vaccinated? Why do we take vaccines on most arm? Often people ask these questions, and ask about the science behind vaccination on the arm. But every time you feel disappointed. However this time it will not happen. Today we will tell you the answers to all these questions.

Why are muscles so important to vaccines?

Most but not all vaccines are given in the muscle. These are called intramuscular injections. Some vaccines such as Rota Virus vaccines are given through the mouth. Other vaccines, such as measles, are given under Rubella's skin. However, many other muscles are given. But why is muscle so important and why is its location important? Why are the arm muscles in the upper shoulder called deltoid? Let's know ...

Immunization cells occur in muscles

According to the study, muscles are the best place to vaccinate, because muscle tissues hold important immunization cells. These immunization cells identify the antigen (s) of the virus and bacterium transplanted through the vaccine and activate the immune system to produce antibodies.

Vaccine works in the body through this process

However, antigens are not added to the Kovid-19 vaccine, but rather are designed to produce antigens through the vaccine. Immune cells present in the muscle capture these antigens and present them to the lymphatic membrane. Vaccination in the muscle tissue (Tissue) keeps the vaccine locally, and the immune cells there warn other immune cells to function.

Immunization cells identify vaccines

Once the vaccine has been identified by the immune cells, these cells carry the antigen into the lymphatic tube, which carries the antigen containing the immune cells to the lymphatic membrane. Which is an important part of our immunization system. It is here that there are more immunization cells, which identify the antigens present in the vaccine and start the immunization system to make antibodies.

That's why vaccines are applied in the upper part of the shoulder

At the place of vaccination, there is a swarm of lymph nodes. For example, many vaccines are applied in deltoid because the lymph nodes are just below the armpits. When the vaccine is applied to the thigh, the lymphatic tube does not have to travel much distance to reach the swarm of the lymph nodes present in the groin. She keeps muscle activities local. Muscle tissue also localizes the vaccine response.

How is the vaccine selected?

Vaccination in Deltoid may be locally inflammatory or painful at the place of vaccination. If such vaccines are applied in a thick tissue, there is a risk of discomfort or swelling because the blood does not circulate properly in the obese tissue, because some components of the vaccine will not be absorbed properly. Vaccines contain some adjuvants or ingredients that enhance immunity to antigens. It should be given to the muscles to avoid discomfort and swelling. There are several ways in which they support a strong immune response.

That's why the vaccine is applied in the thigh of a small child

Another important factor in deciding the location of a vaccine depends on the size of the muscle. Adults and children three years or above are vaccinated in the deltoid in the upper arm. With these, a small child is vaccinated in the middle of the thigh because their arm is short and less developed. Another aspect in choosing the place of vaccination is convenience and patient acceptance.

Sleeve top is easier than taking off pants

Can you imagine taking off the pants at the big vaccination center? Sleeves are easier to top and are more preferred. In infectious diseases such as flu sessions and epidemics like Kovid-19, our public health system needs to have more people vaccinated in the shortest possible time. For this reason the vaccine is given on the arm because the upper part of the arm is easily accessible. After considering all these aspects, most adults and children prefer to be vaccinated on the arm when the flu or Kovid-19 is vaccinated.
