, Vaccinations are an important part of maintaining healthy lifestyles around the world. It is
important to be vaccinated, especially when international trips are made to countries that have
high rate of infectious illnesss. The chances of developing an illness, which could be life
threatening, are very high without the proper vaccinations. Also, once the illness is contracted,
one can pass it on to others who are not vaccinated. Prior to the discovery of vaccinations, some
illnesss were so deadly and highly contagious that they could destroy entire populations of
people. Some immunizations, like the flu immunization, and rabies are commonly used. There
are immunizations for both people and animals. There are pros and cons for the use of each
immunization used, and what they are they? Some of the pros and cons are that they can prevent
certain illnesss, but they can cause nasty side effects or be ineffective in some people.
There are some immunizations that we’ve been using for over 200 years. In 1796, a
immunization for smallpox was created by Edward Jenner. (The History of smallpox, 2015)
Through his study, he came across a theory that if a person got cowpox first, that they couldn’t
get smallpox.
Smallpox is known to be highly contagious, and infectious.
There are many bacteria, parasites, and pathogenes that can cause illnesses. There are
several immunizations that are associated with illnesses and illnesss. In order for immunization
to be effective, it must produce an resistant response to a specific pathogen (pathogen, bacteria,
etc.). All immunizations work by tricking the body into mounting an resistant response to a
perceived illness. The body actually has not been infected by the organism, but thinks it has.
Immunizations are produced in a variety of wars. Some immunizations use heat killed bacteria.
The body recognised the bacteria and responds, but since the bacteria is heat killed, it cannot
cause the illness. Immunizations have a living pathogens in them, but can’t cause harm. Subunits
