Advances in pulmonary immunology

Advances in pulmonary immunology often begin with better understanding of the mechanisms of pulmonary defenses. This leads to new technologies or better use of existing technologies to prevent pneumonia. These can be validated in challenge models, but ultimately, advances in pulmonary immunology come from demonstration that a management strategy reduces the burden of disease in a production setting. This can be difficult, and may require team efforts from producers, allied industry, and academia. Each team member brings a unique perspective and set of resources to the endeavor. The alternative is to use immunoenhancing management strategies based on extrapolation and faith.
