Vaccines Prevent The Human Race - 1697 Words

â€Å"Vaccines prevent an estimated 2.5 million deaths among children younger than age 5 every year, [however;] 1 child dies every 20 seconds from a disease that could have been prevented by a vaccine† (Global Health Security: Immunization). Providing immunity to human, vaccines have saved countless lives through one simple injecting and have eradicated many diseases that used be common among people. Vaccines is the solution and allow us to be able to combat diseases that have overwhelmed humans for centuries. Having this preventative practice has been extremely beneficial and vital to the well-being of the human race. Through the year of the first vaccines, it had proven a big stride in treating and preventing diseases from occurring in†¦show more content†¦Immune’s system role is to identify a pathogen, search for it, and destroy it. The major function of the immune system is â€Å"to protect the body from infection† (Alder and Fleming). The immune sys tem is able to make antibodies are able to attack the pathogen and eliminate from the body. The initiation of â€Å"antibody production through exposure to antigens, [labels for pathogens to allow antibodies to search and attack], results in active immunity† (Alder and Fleming). These antigen are unique markers that allow antibodies to identify the pathogen and prepare for the attack. With vaccines, people’s immune system are able to remember the pathogen that have entered their system for a later encounter, which provides them with this artificial immunity. The immunity provided by vaccination will perceive the recipient’s entire life span and can go stronger through exposure to same antigen on the pathogen. This immunity can help the recipient and the public. This allows the immune system to be activated by the deceased or weakened germ and to be able to remember the object to become immunized to it. The ability to mimic infection without receiving an infectio n is the key role to vaccines and how they ae so effective in preventing diseases. With the usage of the immune system’s function, humans are able to construct
