Vaccines are made of viruses or bacteria that originally cause the diseases. In order to make this viruses and bacteria usable as a vaccine, scientists choice one of the three basic methods depending on the vaccine they want to produce. The first method is using weak version of the virus causing the disease. They weaken the virus by limiting its production using chemical material. This method helps produce small amount of the virus to stimulate the immune system without harming the body. Scientists use it to make vaccines for diseases like measles, chickenpox, and mumps. (“ Weaken the Virus”1,2,3). The benefit of this method is providing a life lasting immunity for the person with one or two doses of the vaccine.( “Weaken the Virus” 9,10). However, this type of vaccine can not be used for people with low immune system .(“ Weaken the Virus” 10,11).
The second method is using dead virus that does not produce any viruses, but still has its character. Vaccines for diseases like polio and influenza usually use this method .(“ Inactivate the Virus” 2,3). There are two advantages in using this method. One, unlike the weak virus method people with low immune system can use these vaccines. Two, because of the absence of the production system in the virus it can not cause harm to the body.( “Inactivate the Virus” 7,8). The disadvantage is it needs multiple doses to get immunity. (“Weaken the Virus” 10,11).
