Medical Video: A Message for the Anti-Vaccine Movement
A vaccine is an antigenic material that is used to produce immunity to a disease. Provision of vaccines (immunization) is carried out to prevent or reduce the influence of infectious diseases. However, some people may doubt the benefits and safety of this vaccine. Because, some people actually get sick or have a fever after the vaccine. To correct this, see the following explanation.
How the vaccine works
Vaccines work by training the immune system to recognize and fight germs, including bacteria or viruses. To do this, antigens, which are certain molecules from germs, must be inserted into the body to trigger an immune response. However, antigens from germs used in immunization are weak forms (or sometimes forms that are dead so they are inactive). So it's not the disease itself that will enter your body.
By injecting antigens into the body through immunization, the immune system can recognize and record the seeds of disease by producing antibodies.
These antibodies will fight the germs before they spread and cause disease. Then, antibodies that have recorded the seeds of this disease as dangerous organisms will recognize it if one day it returns to the body. Without the "recordings" obtained during immunization, your antibodies may not be able to immediately react to attack the seeds of the disease because they do not know how dangerous the disease is.
Are we sure to get sick after the vaccine?
Yes, you might experience pain after the vaccine, this is a side effect of the vaccine.
Vaccines like other drugs can cause side effects. However, most vaccines rarely cause serious side effects. The risk of vaccine side effects is still far lower than the risk of contracting a vaccine-preventable disease.
Each type of vaccine has different side effects, most of which are mild. Common side effects include:
- Temporary pain
- Redness, swelling, or pain at the injection site
- Flu-like symptoms or not feeling well (mild fever, abdominal pain, vomiting, loss of appetite, and headache)
These side effects appear shortly after the vaccine is given, usually only 1-2 days. However, if you experience ongoing symptoms, immediately consult a doctor.
Even so, vaccines can also cause serious side effects. However, this is indeed very rare. The following are some of the severe side effects that might occur based on the type of vaccine.
- Live attenuated(LAV) for example after the measles vaccine. The MR vaccine for measles can cause a severe allergic reaction from the fluid contained in the vaccine, or it is called anaphylactic shock.
- Inactivates,this includes pertussis. This vaccine causes hypotonic side effects and hyporesponsive episodes.
- Toxoid, this includes the TT (tetanus) vaccine. This vaccine can cause anaphylactic shock and brachial neuritis.
Therefore, before you make an immunization, always tell your doctor or nurse if you have allergies or have experienced an allergic reaction to a vaccine before. Because it will be possible for someone to be allergic to vaccines, but this is very rare.
What makes people sick or fever after a vaccine?
Vaccines provide the defense of the body's immune system to form specific defenses against infections from viruses and bacteria.
When immunizing, your body is injected with foreign substances or antigens. Then, the body will provide an immune response in the same way as when the body is suffering from an illness, but the body does not show symptoms of the disease.
When the body is exposed to the same disease later on, the immune system can respond quickly to prevent the development of the disease.
This form of response causes you to experience pain or other side effects from the vaccine. The body forms a new immune system that is stimulated by a vaccine that is inserted into the body, causing you pain. Therefore, getting sick after the vaccine is actually still reasonable and not dangerous.
However, not everyone experiences side effects after the vaccine. Everyone shows a different response after the vaccine. You may also stay healthy and fit, not feeling any side effects.
