Our drive-through simulation has been developed and parameterized based on the past and current best practices available for drive-through design, settings, and operations. However, because the details of a potential SARS-Cov-2 vaccination protocols are not available yet, our drive-through mass vaccination simulation tool can be further tuned as new information becomes available. For example, the vaccination and recovery times may be very much influenced by the specific immunization protocols for SARS-Cov-2 vaccine, which may be different from previous vaccination. In the absence of real drive-through cases, such simulations can play a significant role in pre-planning.
