Suppose a new vaccine that prevents the SARS virus is discovered. Each injection costs $10 and is expected to save 1 in 15,000,000 lives. What is the total cost per life saved for this vaccine? Would you support a government-sponsored program to vaccinate each citizen? Would your response change if a huge epidemic of SARS broke out and the injections would save 1 in 1000 lives? Explain why.
