How do immunization work?
Immunization works by helping the body to prepare antibodies in the fight against the disease. This is done by injection of the body with a small amount of living or dead virus that causes an immune response from the body. This immune reaction will occur not only in vaccination, but also with the future exposure to the virus. If a person were immunized against the disease, exposure to the disease would immediately create an immune response, thereby protecting the person from a real disease. Exposures and contractions of one virus often leave an immune person throughout their lives and is a way to create your own immunization. This does not mean that a person will not have similar viruses with similar symptoms as in many rhinos, which cause common colds. However, it can be noted that in some family, children will receive rhinos who do not get parents. This tends to be because parents have already had this particular virus in the past and are now immune to it.
Several viruses do not cause lifelong immunity. Some recorded examples JSOU respiratory syncytic virus (RSV). Children endangered can receive immunization for RSV when they are young, but after the cessation of immunization does not remain immunization. In addition, they can get RSV more than once.
, however, most immunizations earn the body's ability to become immune to many types of viruses. Instead of waiting for a person to develop natural immunity by infection of the disease, immunization exposes the body of the disease to learn to defend against future exposure.
This is generally considered safer than actually developing immunity by gaining illness. Most viruses or parts of viruses injected can cause a disease for which a person becomes immune. There are several exceptions. Chicken smallpox and measles/mumps/Immunization of Rubella are taken from live viruses. In rare cases, a child may develop one of these viruses after immunization, but cases are relatively mild.
bagThe tin against oral palsy also brought a certain risk for contractual palsy. This has been very rare and instead of polio (IPV) vaccination (IPV) is most often used, using a dead virus. This means that the child cannot get palsy from IPV and is probably immunized for life.
Some immunization does not lead to lifelong immunity. Immunization must often be repeated in early adolescence or early adulthood to continue to provide protection from disease. Many have found that the recommendation of a doctor when immunization has changed over time. It is recommended to consult a doctor about new recommendations for immunization, especially for seniors, and for children.
Some viruses are known for not being stopped by immunization. This was the case of HIV vaccination. The HIV problem when it comes to vaccination is that HIV attacks cells that usually evoke an immune response. Because these cells are deactivated, they are not able to fight the virus. While someRé drugs helped to reduce the severity of HIV, no one has yet been able to develop a vaccine, which would cause immune cells to correspond properly.
It is also HIV Retrovirus, which means that it tends to change its shape when the body is trying to fight. Thus, the injection of the dead HIV virus into man could mean that the body could fight one form of HIV, but it would not be able to get to know or fight it in other forms.
To learn more about the body's immune reaction can result in HIV vaccination later, but many scientists conclude that it is not so close to this. In many diseases, however, new vaccines can help significantly reduce the risk of serious disease. New vaccination for human papillomavirus is a significant step towards reducing the occurrence of cervical cancer.
