Ngasekuqaleni kwaleli hlobo, kuzwakala sengathi ubhubhane lwe-COVID-19 seluphelile. Abantu abagonywe ngokuphelele batshelwa yiCenters for Disease Control and Prevention ngoMeyi ukuthi abasadingi ukugqoka izifihla-buso ezindaweni eziningi, futhi nenani lamacala e-COVID-19 e-U.S nawo anciphile okwesikhashana. Kodwa-ke, okuhlukile kwe-Delta (B.1.617.2) kwaqala ngempela ukubuyisela ikhanda layo elibi.

Ukuhluka kweDelta kubhekele cishe amaphesenti angama-82 wamacala amasha we-COVID-19 e-U.S. Kusukela ngoJulayi 17, ngokusho kwedatha evela kuCDC. Iphinde yaxhunyaniswa nengozi ephakeme engamaphesenti angama-85 yokulaliswa esibhedlela kunezinye izintambo, futhi ingadluliseka ngamaphesenti angama-60 kunokwehluka kwe-Alpha (B.1.17), uhlobo olwalubusa phambilini, ngokocwaningo lwangoJuni 2021.

Izifundo zakamuva ezivela eNgilandi naseScotland ziphakamisa ukuthi umuthi wokugoma iPfizer awusebenzi kangako ekuvikeleni ekuhlukeni kweDelta njengoba kunjalo nge-Alpha, ngokwe-CDC. Manje, lokho akusho ukuthi umuthi wokugoma awukwazi ukukusiza ukuthi ugweme isifo esinezimpawu ezivela ohlotsheni oluthile - kusho nje ukuthi awusebenzi kahle ekwenzeni kanjalo uma uqhathaniswa nekhono lawo lokulwa ne-Alpha. Kepha ezinye izindaba ezingaba mnandi: NgoLwesithathu, uPfizer umemezele ukuthi umthamo wesithathu womuthi wokugoma we-COVID-19 ungakhuphula ukuvikelwa kokuhlukile kweDelta, ngaphezu kwalokho kusuka emithamo yayo emibili yamanje.

Imininingwane ethunyelwe ku-inthanethi ivela ku-Pfizer iphakamisa ukuthi umthamo wesithathu womuthi wokugoma unganikeza ngaphezu kokuphindwe kahlanu amazinga e-antibody ngokuqhathaniswa nokwehluka kwe-Delta kubantu abaphakathi kweminyaka eyi-18 nengama-55 uma kuqhathaniswa nalokho okusuka kumashothi amabili ajwayelekile. Futhi, ngokusho kokutholwe yinkampani, i-booster yayisebenza kakhulu kubantu abaneminyaka engama-65 kuya kwengama-85 ubudala, ikhuphula amazinga e-antibody acishe abe yi-11 phakathi kwaleli qembu. Konke okushiwoyo, ukusethwa kwedatha bekukuncane - abantu be-23 kuphela abathintekayo - futhi okutholakele kusazobuyekezwa kontanga noma kushicilelwe kumagazini wezokwelapha okwamanje.

"Siyaqhubeka nokukholelwa ukuthi kungenzeka ukuthi kudingeke ukuthi kuthuthukiswe umthamo wesithathu esikhathini esiyizinyanga eziyisithupha kuya kwezingu-12 ngemuva kokugonywa ngokuphelele ukuze kugcinwe amazinga aphezulu okuvikela, kanti futhi kwenziwa ucwaningo lokuhlola ukuphepha nokungabi namandla komzimba komthamo wesithathu," kusho uMikael UDolsten, MD, Ph.D., oyisikhulu esiphezulu kwezesayensi kanye nomongameli we-Worldwide Research, Development, ne-Medicalfor Pfizer, esitatimendeni ngoLwesithathu. UDkt. Dolsten uqhubeke wengeza, "Le datha yokuqala ikhuthaza kakhulu njengoba i-Delta iqhubeka nokusabalala."

Ngokusobala, ukuvikelwa okunikezwa umgomo ojwayelekile we-Pfizer wemithamo emibili kungase kuqale "ukuncipha" ezinyangeni eziyisithupha ngemuva kokugonywa, ngokwethulwa kwesikhulu sezemithi ngoLwesithathu. Ngakho-ke, umthamo wesithathu ongaba khona ungasiza kakhulu, ngokulula, ukuvikela ukuvikelwa kwabantu kwi-COVID-19 isiyonke. Kubalulekile ukuqaphela, nokho, ukuthi amazinga e-antibody - nakuba kuyisici esibalulekile sokuzivikela komzimba - akuwona kuphela i-metric yokukala amandla omuntu okulwa naleli gciwane, ngokusho kombiko. I-New York Times. Ngamanye amagama, isikhathi esiningi nocwaningo luyadingeka ukuqonda ngempela ukuthi ngabe umthamo wesithathu kaPfizer, uyiphutha, konke kuqhekeziwe.

Ngokungeziwe ku-Pfizer, abanye abenzi bomuthi wokugoma nabo baye bawusekela umbono we-booster shot. Umsunguli weModerna uDerrick Rossi utshele Izindaba ze-CTV ekuqaleni kukaJulayi lapho kuzodingeka isibhamu esivamile somuthi wokugomela i-COVID-19 “cishe” ukuze kugcinwe ukuzivikela ngokumelene naleli gciwane. URossie uze wathi, "Kungenzeka kungamangalisi ukuthi sidinga i-booster shot njalo ngonyaka." (Okuhlobene: Ungase Udinge Umthamo Wesithathu Womgomo we-COVID-19)

Isikhulu esiphezulu sikaJohnson & Johnson u-Alex Gorsky naye wagxuma esitimeleni esithuthukisa esikhathini esizayo ngesikhathi I-Wall Street Journals Tech Health ekuqaleni kukaJuni, ethi umthamo(imitha) owengeziwe kungenzeka udingekile ekugomeni kwenkampani yakhe - okungenani kuze kube yilapho ukuzivikela komhlambi (okungukuthi lapho iningi labantu lingagonyiwe ezifweni ezithathelwanayo) kufinyelelwa. "Kungenzeka ukuthi sibheka lokhu kumaka kanye nokudutshulwa komkhuhlane, cishe eminyakeni embalwa ezayo," engeza.

Kodwa ekuqaleni kukaJulayi, i-CDC kanye ne-Food and Drug Administration bakhiphe isitatimende esihlanganyelwe sokuthi "abantu baseMelika abagonywe ngokugcwele abadingi i-booster shot ngalesi sikhathi" nokuthi "i-FDA, CDC, kanye ne-NIH [Izikhungo Zezempilo Zikazwelonke ] babambe iqhaza ohlelweni olunzulu olusekelwe kwisayensi ukubheka ukuthi ngabe i-booster ingadingeka noma nini. "

"Siyaqhubeka nokubuyekeza noma iyiphi idatha entsha njengoba itholakala futhi sizogcina umphakathi unolwazi," sifunda isitatimende "Sizilungiselele imithamo ekhuthazayo uma futhi isayensi ibonisa ukuthi iyadingeka."

Empeleni, ngoLwesithathu uDkt.Dolsten uthe uPfizer "usezingxoxweni eziqhubekayo" nezinhlangano ezilawulayo e-U.S. Mayelana nomthamo wesithathu wokufukula womuthi wamanje. Uma ama-ejensi enquma ukuthi kunesidingo, uPfizer uhlela ukufaka isicelo sokugunyazwa sokusetshenziswa okuphuthumayo ngo-Agasti, ngokusho kukaDkt Dolstein. Ngokuyisisekelo, ungathola i-COVID-19 booster shot ngonyaka olandelayo.

Imininingwane ekule ndaba inembile njengesikhathi sokushicilela. Njengoba izibuyekezo mayelana ne-coronavirus COVID-19 ziqhubeka nokuvela, kungenzeka ukuthi ulwazi oluthile nezincomo kule ndaba kushintshile kusukela ekushicilelweni kokuqala. Sikukhuthaza ukuthi uhlole njalo izinsiza ezifana ne-CDC, i-WHO, kanye nomnyango wezempilo womphakathi wendawo ukuze uthole imininingwane yakamuva nezincomo.
