Si ka duwan tallaalo kale oo badan oo ay ku jiraan cudur-sidaha faafa ama qayb ka mid ah, tallaalada fayraska fayraska waxay isticmaalaan fayras aan waxyeello lahayn si ay u gaarsiiyaan qayb ka mid ah code-ka hiddaha unugyadeena, taas oo u oggolaanaysa inay sameeyaan borotiinka cudur-sidaha.Tani waxay tababaraysaa habdhiska difaaca si uu uga falceliyo caabuqyada mustaqbalka.
Marka aan qabno caabuqa bakteeriyada ama fayraska, habka difaacayagu wuxuu ka falceliyaa molecules-ka cudur-sidaha.Haddi ay tahay kulankayagii ugu horeeyey ee aan la kulano soo duulayaasha, habab si fiican loo habeeyey ayaa isu yimaada si ay ula dagaallamaan cudur-sidaha oo ay u dhisaan difaacyada kulamada mustaqbalka.
Tallaal dhaqameed badan ayaa keena jeermiska faafa ama qayb ka mid ah jirkeena si ay ugu tababaraan nidaamka difaaca si aan uga hortagno soo-gaadhista mustaqbalka ee cudur-sidaha.
Tallaalka fayraska fayraska ayaa si kala duwan u shaqeeya.Waxay adeegsadaan fayras aan waxyeello lahayn si ay qayb ka mid ah koodka hidde-sideyaasha u gaarsiiyaan unugyadeena si ay ugu ekaysiiyaan caabuqa.Fayraska aan waxyeellada lahayn wuxuu u shaqeeyaa sida habka dhalmada, ama vector, ee taxanaha hidaha.
Unugyadeenu waxay markaas sameeyaan borotiinka fayraska ama bakteeriyada ee uu fayrisku keenay waxayna u soo bandhigaan habdhiska difaaca.
Tani waxay noo ogolaanaysaa inaan horumarino difaac gaar ah oo ka hortaga cudur-sidaha iyada oo aan loo baahnayn infekshan.
Si kastaba ha ahaatee, fayraska laftiisa ayaa door dheeraad ah ka ciyaara isagoo kor u qaadaya jawaab celinta difaacayada.Tani waxay keenaysaa falcelin ka adag marka loo eego haddii habka hidde-sideyaasha cudur-sidaha keligiis la keenay.
Tallaalka Oxford-AstraZeneca COVID-19 wuxuu isticmaalaa fayruuska hargabka caadiga ah ee chimpanzee loo yaqaan ChAdOx1, kaas oo bixiya koodka u oggolaanaya unugyadeena inay sameeyaan borotiinka sare ee SARS-CoV-2.
