How do I prepare myself to become a scientist in a biotech/pharm industry?

<p>Goal: To become a biomedical scientist working preferebly for genentech or novartis. I am very interested in vaccine research and infectious diseases. </p>

<p>What do biotech/pharmaceutical companies prefer? Also, what PhD concentration would be mostly sought after for scientist positions? Would they rather take a PhD in immunology rather than a PhD in translational molecular biology? Please help!</p>
