During the time that the infected Cylons are held captive aboard Galactica, Dr. Cottle creates a simple vaccine that dramatically reverses the effect of the virus on said Cylons. However, an antibody in their blood breaks down the vaccine's RNA backbone, rendering the treatment useless. Because of that, the Cylons require regular close interval injections of the vaccine, or their condition significantly worsens. If regular injections are provided, an infected Cylon could be kept alive indefinitely.
