Immunization Meaning in Medical

Immunization meaning is an infectious disease prevention program implemented by administering vaccines so that people are immune or resistant to the disease. The immunization program starts from the age of infants hinggan enter school age. Through this program, children will be given a vaccine that contains certain types of bacteria or viruses that have been weakened or disabled to stimulate the immune system and form antibodies in their body. Antibodies formed after immunization are useful to protect the body from the attack of bacteria and viruses in the future.

Vaccine delivery methods in immunization vary, some are injected, put (dripped) into the mouth, or even sprayed into the mouth or nose. A number of vaccines are given only once in a lifetime and there is also a need to be given periodically so that the immune system is perfectly formed.

Newborns do have antibodies from their mothers received while still in the womb, but this immunity can last only a few weeks or months. After that, the baby will become susceptible to various types of diseases and need to start producing its own antibodies. By immunization, the child’s immune system will be ready for future infectious diseases, such as smallpox, measles, polio, tetanus, and mumps, according to the type of vaccine given. Immunization can also help prevent epidemics of infectious diseases as well as reduce spending because prevention costs are cheaper than medical expenses.

Side Effects of Immunization

Generally the side effects of immunization are mild, for example:

  • Pain or scar is reddish in the injected part
  • Fever
  • Nausea
  • Dizzy
  • Missing appetite

For severe side effects (eg seizures and allergic reactions), rarely occur.
Consider again if you plan not to include children in the immunization program because the risk of side effects of vaccination itself is less than its lifetime benefit.
