Kupita patsogolo kwa katemera wa coronavirus 'kulonjeza'

Kuyesa kwachipatala kwa gawo lachiwiri la katemera wa COVID-19 wopangidwa ndi Academy of Military Medical Science ndi kampani yaku China ya CanSino Biologics yapeza kuti ndiyotetezeka ndipo imatha kuyambitsa kuyankha kwa chitetezo chamthupi, malinga ndi kafukufuku wofalitsidwa mu magazini yachipatala ya The Lancet pa. Lolemba.

Komanso Lolemba, The Lancet inafalitsa zotsatira za mayesero a gawo loyamba ndi lachiwiri la katemera wofanana ndi adenovirus vectored opangidwa ndi asayansi ku Oxford University ndi kampani ya biotech AstraZeneca.Katemerayu adawonetsanso kupambana pachitetezo komanso potency motsutsana ndi COVID-19.

Akatswiri adatcha zotsatirazi "zolonjeza".Komabe, mafunso okakamiza amakhalabe, monga kutalika kwa chitetezo chake, mlingo woyenera woyambitsa kuyankha kwamphamvu kwa chitetezo cha mthupi komanso ngati pali kusiyana kwapadera kwa wolandira monga zaka, kugonana kapena fuko.Mafunso awa adzayankhidwa m'mayesero akuluakulu a gawo lachitatu.

Katemera wa adenovirus vectored amagwira ntchito pogwiritsa ntchito kachilombo kozizira kocheperako kuti abweretse ma genetic kuchokera ku coronavirus yatsopano kulowa m'thupi la munthu.Lingaliro ndikuphunzitsa thupi kuti lipange ma antibodies omwe amazindikira mapuloteni a coronavirus ndikuthana nawo.

Pakuyesa kwa gawo lachiwiri la katemera waku China, anthu 508 adatenga nawo gawo, 253 mwa iwo adalandira mlingo waukulu wa katemera, 129 mlingo wochepa ndipo 126 wa placebo.

Makumi asanu ndi anayi mphambu asanu mwa anthu 100 aliwonse omwe adatenga nawo gawo pagulu la mlingo waukulu ndi 91 peresenti mugulu laling'ono lochepa anali ndi mayankho a T-cell kapena antibody patatha masiku 28 atalandira katemera.Ma T-cell amatha kulunjika mwachindunji ndikupha tizilombo toyambitsa matenda, kuwapanga kukhala gawo lofunikira pakuyankha kwa chitetezo chathupi chamunthu.

Olembawo adatsindika, komabe, kuti palibe otenga nawo mbali omwe adakumana ndi kachilomboka atalandira katemera, kotero kukadali koyambirira kunena ngati katemerayu angatetezere ku matenda a COVID-19.

Pankhani yoyipa, kutentha thupi, kutopa komanso kupweteka kwa malo ojambulira zinali zina mwazotsatira zodziwika bwino za katemera waku China, ngakhale zambiri mwazotsatirazi zinali zochepa kapena zocheperako.

Chenjezo lina linali loti vekitala ya katemerayo imakhala kachilombo koyambitsa matenda a chimfine, anthu amatha kukhala ndi chitetezo chokwanira chomwe chimapha wonyamula ma virus katemera asanayambe kugwira ntchito, zomwe zitha kulepheretsa kuyankha kwa chitetezo chamthupi.Poyerekeza ndi achinyamata, okalamba omwe adatenga nawo gawo nthawi zambiri amakhala ndi mayankho otsika kwambiri a chitetezo chamthupi, kafukufukuyu adapeza.

Chen Wei, yemwe adatsogolera ntchito ya katemerayu, adati m'nkhani yofalitsa nkhani kuti anthu okalamba angafunike mlingo wowonjezera kuti chitetezo chamthupi chitetezeke, koma kafukufuku wowonjezera adzafunika kuunika njirayo.

CanSino, yemwe amapanga katemerayu, akukambirana zoyambitsa mayesero atatu m'maiko angapo akunja, Qiu Dongxu, wamkulu komanso woyambitsa nawo CanSino, adatero Loweruka pamsonkhano ku Suzhou, m'chigawo cha Jiangsu.

Mkonzi wotsagana nawo mu The Lancet pa kafukufuku waposachedwa wa katemerayu adatcha zotsatira za mayeso ochokera ku China ndi United Kingdom "zofanana komanso zopatsa chiyembekezo".
