How does the TB vaccine work?

  • All vaccinations work on the same principle. By injecting into the body a material which is chemically similar to a given disease organism (such as the tuberculosis baccilus) the immune system is activated, and will prepare an immune response to that disease before the actual disease organism ever enters the body. Therefore there is a faster and more effective immune response if the disease is ever actually encountered.

    I may desire an hourly pay if I am asked to create a program/script to automate a procedure, there may be considerable amount of time gathering the requirements, investigating how it is currently done and then putting together a project plan on the separate steps that need to be done.
