>given half of America is currently infected Point of order: the ideal test of a vaccine is: Given uninfected || infected but early When disease runs course Then Side effects minimized/non-existent Symptoms and severity of disease minimized. The worst time to test a vaccine is when everyone is in the "Oh snap, infected" situation, as it allows for teasing out of long cycle problems (like say unintentional sterilization or birth defects inducement) before introducing it to the majority of the population. Life hardly ever is that accommodating however.
