In general, the concept behind immunization is similar to that of homeopathic approach of ‘like treating like’. In effect, the body is exposed to a little amount of the organism, causing a particular disease. Though the organisms are modified to make them safe enough for the body, they are rendered with the ability to create the specific infection. With this, the immune system of the body becomes active and produces antibodies to fight the foreign organism.
This process makes the body equipped for fighting against the specific disease. This is because whenever the same organism will enter the system, the immune cells will recognize it and will mount an efficient resistance against it. Thus, vaccination works great deal in strengthening the immunity and protecting the body from fatal diseases. After learning about the advantages, let us move on the disadvantages as well.
Like any other medication, in case of vaccines too, there are certain disadvantages. There exists the risk of adverse reactions with vaccinations as well. Mostly, the reactions associated with vaccinations are minor in nature, including pain or swelling at the injection site, mild fever and irritability. In rare cases, severe reactions have also been noticed. However, the rate of occurrence cannot be determined as side effects are usually not reported and there is very less research being done in the area.

Choi 1Wendy ChoiMrs. StallingsAP Biology (Period 5)12 May 2008The Benefits and Dangers of VaccinationVaccination, also known as immunization, is to receive an injection of prepared killedmicroorganisms, living attenuated organisms, or living fully virulent organisms that isadministered to produce or artificially increase immunity to a particular disease. Immunizationis a subject that evokes very strong opinions and usually stirs up heated debate as to their efficacy, safety, and reliability. The main questions parents have to answer are whether toimmunize or not, and if so, when and with which ones. In an overview, the common benefits of being vaccinated is the total elimination of diseases, the prevention of pandemics and epidemics,an obvious decrease in health care costs, and the prevention of harmful side-effects of certaindiseases. However, an English doctor Sarah Myhill shares her view: “Vaccinations are a twoedged sword because whilst they have the potential to prevent illness, they can certainly causeflares of CFS. Indeed I have several patients with CFS dated from vaccinations such as flu or hepatitis B. However usually this has been on the background of overwhelming stress” (Myhill).Some risks and contradictions to immunization includes the suggestion that a routineimmunization should be deferred during acute febrile illness, atopic dermatitis or acute skin rash,“altered” newborns under six month of age or undeveloped fetus during pregnancy,hypersensitivity to any vaccine component, cases where the patient is undergoingimmunotherapy, and cases where the patient has an altered immunity.
