Millions of people have rolled up their sleeves to get it vaccine against Covid-19. But why are people mostly vaccinated on the side? Most vaccines are injected intramuscularly, and this process is known as intramuscular injection. Disa vaccine, si vaccine e Rotavirus, taken orally.
Others are injected slightly under the skin, such as the measles, mumps vaccine and rubella. But many others are injected into muscle. But why muscle is so important and does the place matter? And why in the arm muscles – called the deltoid – and at the top of the shoulder?
Muscles make an excellent vaccine injection site, as muscle tissue contains important immune cells. These immune cells recognize it antigen, a piece smallpox of a virus or bacteria introduced by the vaccine that stimulates an immune response.
In the case of the COVID-19 vaccine, I am not introducing one antigen, but manages the project for the production of antigen. Immune cells in muscle tissue receive these antigens and present them in nodes lymphatic. The vaccine injection into muscle tissue keeps the vaccine localized, allowing immune cells to sound the alarm on other immune cells and get to work.
Once a vaccine is recognized by immune cells in the muscle, these cells carry it antigen in the lymphatic vessels, which transport the immune cells they contain antigen IN nodes lymphatic. Nodeslymphatic, the main components of our system immune, contain more immune cells they recognize antigens of the vaccine, and begin the process immune of antibody production.
Piles of joints lymphatic, are located in areas near vaccine injection sites.
For example, many vaccines are injected into the deltoid as it is close by joints lymph nodes located just below the armpit. When vaccines are injected into the thigh, the lymphatic vessels do not have much to do to reach the cluster i joints lymphatic in the groin.
Also, muscle tissue tends to stay localized vaccine reactions. injections of a vaccine in the deltoid muscle, may result in local inflammation or irritation at the injection site. If certain vaccines are injected into adipose tissue, the chance of irritation and reaction with inflammation increases, as adipose tissue has a poor blood supply, what that leads to poor absorption of some components of the vaccine.
Vaccines that involve the use of ancillary elements — or ingredients that strengthen itimmune response to antigen – should be done on the muscle to avoid irritation and inflammation. Auxiliary elements act in different ways to stimulate a stronger response immune.
However, another crucial factor at the vaccine injection site is muscle size. Adults and children aged 3 and over tend to to receive the vaccines in the upper arm, precisely in the deltoid.
Younger children get their vaccines in the middle of the thigh, as the arm muscles are smaller and less developed. Another element to consider when administering the vaccine is commodity of the patient.
Can you imagine taking off your pants at a mass vaccination clinic? tuck upethe sleeve is one action too easier and more preferable. Outbreaks appear to be exacerbated during the flu season or in the case of pandemic Covid-19, require our health systems to vaccinate as many people as possible within one short time. For these reasons, it is preferable to get the vaccine on the arm, because the upper part of the arm is easily accessible. (Bota.al)
