The tabs in this editor are organized by vaccine type (this editor also includes bednets) and display the herd effect by age cohort, coverage rate of the vaccine, and affected disease (tabs at the bottom of the table).
Declines in mortality from vaccines are modeled based on vaccine efficacy specific to the child receiving the immunization and a herd effect. The herd effect is modeled as the percent of unprotected children (the sum of unvaccinated population and the vaccine failures) who are protected by the reduced transmission of the disease resulting from increased immunization rates. The parameters for herd effect are entered as the percent of the unprotected population which is protected for five-percentage-point bands beginning at 0 percent coverage. Currently, the defaults for herd effect are zero for all vaccines except Hib, Pneumococcal, Rotavirus, and Measles vaccines. For details on how the herd effects were calculated for various vaccines in LiST, please see this LiST Technical Note |
