Figure 1: Comparison of Vaccine Development Timelines. As time may be of the essence during a Bioterrorism attack, the ability to rapidly produce a vaccine that drives sterilizing immunity to the attack strain may be critical. While the most frequently used platform (Attenuated or Killed virus) may take 5 to 6 months on order to generate a vaccine, that time can be significantly reduced with alternative platforms such as DNA, which has the ability to cut that time in half.
