Zeziphi izitofu ezisebenzayo ngokuchasene ne-delta mutant?

Ngelixa i-Delta mutant isasasazeka kwaye ibeka ulawulo lwayo kwihlabathi liphela, uphononongo olutsha luveze ukuba ukusebenza kwesitofu sokugonya i-Pfizer Biontech anti-Coronavirus ekuthinteleni usulelo oluneempawu ezimandundu ezifuna ukulaliswa esibhedlele, okanye ukufa, kufikelela kwi-90%, kwaye ithatha ixesha elide. iinyanga ezintandathu ubuncinane.

Uphononongo, oluxhaswa ngemali nguPfizer kwaye lupapashwe yi-abc News, lufumanise ukuba xa kufikwa ekuthinteleni usulelo, ukusebenza kwesitofu sokugonya kuncipha ngokukhawuleza ngokuhamba kwexesha, oko kukuthi, kwiinyanga ezi-6 emva kwedosi yesibini, kwaye kuphela ngama-47% asebenzayo ekuthinteleni. usulelo.

Abaphandi baphinde baqwalasela ukuba isizathu sisekwehleni kokusebenza kwesitofu sokugonya ngokuhamba kwexesha, kwaye hayi ekujonganeni neentlobo ezikwaziyo ukusasazeka kunentsholongwane.

Ukusebenza kuncipha ngokuhamba kwexesha

Idatha ibonise ukuba ukusebenza kwesitofu sokugonya i-Delta kwakuyi-93% emva kwenyanga yokuqala, kwaye yehla ukuya kuma-53% emva kweenyanga ezine.

Xa sijongana nolunye utshintsho lwentsholongwane yeCorona, ukusebenza kwehle ukuya kuma-67% ukusuka kwi-97%.

Iziphumo zophononongo zihambelana nedatha epapashiweyo ngaphambili evela kwaSirayeli kunye namaZiko e-US oLawulo lweSifo kunye noThintelo, ajonga ukusebenza kwesitofu sokugonya ngokuhamba kwexesha, kodwa uphononongo oluxhaswe yiPfizer lolokuqala ukujonga ukuba ukwahluka kwedelta kuyichaphazela njani iPfizer. isitofu sokugonya.

Uqhubana njani nomntu ongakuhoyiyo ngobukrelekrele?
