Table 2. Determining Dynamic Health Policies Using Real-Time Data.

At time t = 0
1. Obtain estimates for model parameters (Inline graphic), initial number of susceptibles, Inline graphic, and a prior distribution for random variable Inline graphic.
2. Use Eqs. (7)–(8) to determine the dynamic health policy Inline graphic.
3. Find the optimal number of susceptibles to immunize, Inline graphic, using Eq. (10).
4. Increment time to Inline graphic.
5. Update the number of susceptibles at time Inline graphic: Inline graphic.
While Inline graphic
1. Given the availability of vaccine, use Eq. (8) or Eq. (12) to find the optimal number of susceptibles to immunize, Inline graphic, and the optimal transmission-reducing intervention, Inline graphic.
2. At the end of period Inline graphic, use the real-time data Inline graphic to update the model parameters (using for instance, maximum likelihood estimation) and the dynamic health policy Inline graphic, using Eqs. (7)–(8).
3. Increment time: Inline graphic.
4. Use Table 1 to update the epidemic state at time Inline graphic.
