What is a weakened vaccine?

The weakened vaccine is a vaccine that uses live pathogenic material for the purposes of induction of immunity. The strength of the pathogen is weakened or weakened during the vaccine processing to reduce the disease. Many vaccines including typhoid, tuberculosis, polio, measles, mumps and rubber vaccines can be offered in a weakened form. The cultivated pathogen is introduced in low quantities for the patient, often inhalation, where it multiplies in the body. The immune system, exposed to a pathogen in the form of a weakened vaccine, reacts and develops antibodies so that when someone meets a version of full force, the body will be able to fight.

The idea of ​​a weakened vaccine is that it is strong enough to cause immunity, but too weak but too faint to cause the disease. However, the use of such vaccines was sometimes associated with the disease in some patients. In some cases this seems to be because a lot of vaccines has not been properly processed while in another patient reacted badly or the virus mutated inside the body to become a virulentto him. That is why weakened vaccines are considered to be more risky than killed or inactivated vaccines in which the pathogen is killed before introduction into the body so that he cannot become ill.

Since weakened vaccines can sometimes cause disease, it can be adequately guided to think why they are used at all when inactive vaccines are available and are likely to be much safer. One of the key reasons for using a weakened vaccine is that they are more efficient, while some vaccinations are not available in the killed form. Live vaccines also stimulate a greater reaction of the immune system, lead to the development of more antibodies and provides longer -term immunity. In addition, they are less expensive to produce than killed vaccines, which is appealing to a quick effort for a pile.

When someone is vaccinated by a weakened vaccine, it is not uncommon to develop some minor symptoms of the disease such asFever, fatigue or slowness as the body's immune system reacts. The physician may discuss the common side effects of specific vaccines with patients and their families, and the physician may also speak of more serious side effects. It is generally assumed that the personal and social benefits of vaccination outweigh risks, but there are certain specific circumstances in which it may be dangerous to someone, which is crucial for a doctor or nurse to provide a complete history before vaccination or strengthening.
