Vaccination vs. Immunization
Vaccination and immunization are both processes used to provide protection from various diseases. Both involve the introduction of a biological agent, such as a virus or bacteria, into the body in order to induce an immune response. However, there are some key differences between the two.
Vaccination
Vaccination is the process of introducing a weakened or killed form of a virus or bacteria into the body to protect against a future infection. Vaccines work by triggering the body’s immune system to create antibodies against the disease. Vaccines are often administered through injection, but can also be administered orally or through a nasal spray.
Immunization
Immunization is the process of introducing an antigen, such as a virus or bacteria, into the body to stimulate an immune response. This response is usually in the form of the body producing antibodies to fight the antigen. Unlike vaccination, immunization does not involve the introduction of a weakened or killed form of the virus or bacteria, but rather a live version of the antigen. This means that immunization can provide more effective protection against disease, but can also cause more severe side effects.
