Namhlanje, i-US FDA ibhengeze ukuvunywa kweyeza elitsha le-SIGA Technologies i-TPOXX (tecovirimat) lokunyanga i-smallpox. Kubalulekile ukukhankanya ukuba eli liyeza elitsha lama-21 elivunyiweyo yi-US FDA kulo nyaka kwaye liyeza elitsha lokuqala elivunyiweyo lokunyanga i-smallpox.
Igama le-smallpox, abafundi beshishini lezonyango abayi kuba baqhelekile. I-smallpox vaccine yeyona vaccine yokuqala eyenziwe ngempumelelo ngabantu, kwaye sinesixhobo sokuthintela esi sifo sibulalayo. Ukusukela oko kwagonywa i-smallpox vaccine, abantu baye baphumelela kwimfazwe yokulwa neentsholongwane. Ngo-1980, i-World Health Organisation yabhengeza ukuba siyisusile ingozi ye-smallpox. Olu hlobo lwesifo esosulelayo, esiye sachaphazeleka kakhulu kwaye kuthethwe ngaso, siye saphela kancinci kancinci emehlweni abantu.
Kodwa ngenxa yobunzima bemeko yamazwe ngamazwe kule minyaka ingamashumi eminyaka, abantu baqala ukuxhalaba kukuba intsholongwane ye-smallpox inokwenziwa izixhobo zebhayoloji, nto leyo esongela ubomi babantu abaqhelekileyo. Ngenxa yoko, abantu bagqibe ekubeni benze iyeza elinokunyanga i-smallpox xa kukho imeko engxamisekileyo. I-TPOXX yavela. Njengeyeza elilwa neentsholongwane, linokujongana ngempumelelo nokusasazeka kwentsholongwane ye-variola emzimbeni. Ngokusekelwe kumandla alo, eli yeza litsha linikwe iziqinisekiso ezikhawulezileyo, iziqinisekiso zokujonga kuqala, kunye neziqinisekiso zamayeza eenkedama.
Ukusebenza kakuhle kunye nokhuseleko lwale chiza litsha kuye kwavavanywa kwizilingo zezilwanyana kunye nabantu, ngokulandelelana. Kwizilingo zezilwanyana, izilwanyana ezosulelwe yi-TPOXX ziphile ixesha elide kunezo ziphathwe nge-placebo emva kokosulelwa yintsholongwane ye-variola. Kwizilingo zabantu, abaphandi baqeshe abantu abangama-359 abasempilweni (abangenalo usulelo lwe-smallpox) baza babacela ukuba basebenzise i-TPOXX. Izifundo zibonise ukuba iziphumo ebezingalindelekanga eziqhelekileyo yintloko ebuhlungu, isicaphucaphu, kunye nentlungu yesisu ngaphandle kweziphumo ebezingalindelekanga ezinzulu. Ngokusekelwe ekusebenzeni kakuhle okubonakaliswe kwizilingo zezilwanyana kunye nokhuseleko olubonakaliswe zizilingo zabantu, i-FDA ivumile ukuqaliswa kwale chiza litsha.
“Ngenxa yokusabela kwingozi yobugrogrisi be-bioterrorism, iCongress ithathe amanyathelo okuqinisekisa ukuba iintsholongwane zisetyenziswa njengezixhobo, kwaye siye saphuhlisa saza savuma amanyathelo okulwa. Imvume yanamhlanje imele inyathelo elikhulu kule mizamo!” UMlawuli we-FDA uScott Gottlieb Ugqirha uthe: “Eli liyeza lokuqala elitsha elinikwe uphononongo oluphambili lwe-'Material Threat Medical Countermeasure'. Imvume yanamhlanje ikwabonisa ukuzibophelela kwe-FDA ekuqinisekiseni ukuba sikulungele ingxaki yempilo yoluntu kwaye sibonelela ngokhuseleko ngexesha elifanelekileyo. Iimveliso zamayeza amatsha ezisebenzayo.”
Nangona eli yeza litsha kulindeleke ukuba linyange i-smallpox, sisalindele ukuba i-smallpox ayizukubuya kwakhona, kwaye silindele imini apho abantu bangasayi kuze bayisebenzise le yeza litsha.
