Notice to Readers: Availability of Maxi-Vac Alternative

Maxi-Vac Alternative, a public use software program, is now available. Maxi-Vac Alternative was developed by CDC to help public health officials plan smallpox vaccination clinics in the event of a bioterrorist attack. Maxi-Vac Alternative allows planners to refine human resource allocations (e.g., physicians and nurses) at clinics, with the goal of maximizing patient flow-through. Maxi-Vac Alternative is a companion program to Maxi-Vac 1.0, which was released in 2003. The two programs differ in terms of the time patients will require at each station (e.g., pre-vaccination screening and vaccination) and the selections the user can make for number of personnel, size of patient pre-vaccination orientation rooms, and the need for vaccination witnesses. Because no one scenario can describe all contingencies of an emergency mass smallpox vaccination campaign, users should examine both versions before deciding which version to use.

Both Maxi-Vac Alternative and Maxi-Vac 1.0 and their manuals can be downloaded from Both programs and manuals are in the public domain and may be used and copied without permission; however, citation as to source (provided in the manuals and in online help functions) is appreciated.
