Assessing Vaccine Efficacy and Data

Abstract

To scientifically choose a vaccine or design a vaccination program it is necessary to consider many variables.⁷ Some of these include: 1.) presence and degree of challenge of the particular diseases on the farm or ranch; 2.) management practices on the facility that lend themselves to or hinder vaccination programs; 3.) at what times or ages are the disease problems occurring, and are they associated with any stresses; 4.) what immune system components are necessary to afford protection against the various disease; 5.) some basic immunology concepts; 6.) the information that is available on products being considered, and the source and quality of the information.
