Thermotolerant Vaccines: A Game Changer?
The Serengeti Health Initiative (SHI)—cofounded byWashington State University and Lincoln Park Zoo(Chicago)—has,since2003,beencontrollingrabiesthroughtheimplementationofannualmassdograbiesvaccinationcampaignsinremotevillagesinnorthernTanzania.Theeffectivenessofcampaignssuchasthese,andtheepidemiologicalfeaturesthatmakeeliminationfeasible(e.g.,effectivevaccinesareavailable;domesticdogs,notwildlife,arethereservoirofinfection;and rabies has a relatively low R0 (thenumberofsecondaryinfectionsproducedfromaprimarycase))haveledtheWorldHealthOrganization(WHO),togetherwiththeFood&AgriculturalOrganization(FAO)and the World Organization for AnimalHealth(OIE),torecognizecanine-mediatedhuman rabies as a global health priorityand to unite in a tripartite commitmenttoitsglobaleliminationby2030.Whetherthis commitment is met with successwill, in part, be determined by vaccinedeliveryprogramsbeingabletoovercomethe logistical problems associated withrampingupfromthesmalltotheregionalscale. One constraint that poses a particularproblem is the difficulty of achievingvaccination coverage of 70% of the dogpopulationconsistentlyacrossthevastandremoterural landscapesthatcharacterizemuchofsub-SaharanAfrica and Asia. With the elimination of rabies critically dependent on contiguous vaccination coverage,evensmallpocketsoflowcoverage(e.g.,involving<0.5%ofthedogpopulation)willcausesignificantdelay.Consequently,ifthelarge,coalescent,disease-freezonesnecessaryforregionaleliminationaretobecreated,itwillbeessentialtoovercomethisconstraint.
