The national disease control authority has hired your team to help manage flu vaccine production. Key facts: The problem is serious. Even in a year without vaccine shortages, ~36,000 deaths, 200,000 hospitalizations, $20 billion productivity loss. Demand for influenza vaccinations is expected to be 100 million. Actual nationwide demand is uncertain, but can be approximated with a normal distribution with mean mu = 100 million and standard deviation sigma = 10 million. A shortfall in vaccine supply exceeding 10 million doses is considered be unacceptable. One of the critical goals of the national vaccination policy is to ensure that the probability of such shortfall does not exceed 5%. Each year a new virus is targeted, so the vaccine formulation from one year cannot be used the following year. At the end of each flu season, all unused vaccines need to be discarded. What is one of the critical goals of the national vaccination policy?
1) To minimize the number of deaths caused by the flu
2) To reduce the number of hospitalizations due to the flu
3) To minimize the economic loss caused by the flu
4) To ensure a sufficient supply of flu vaccines
