Kafukufuku woyambirira akuwonetsa kuti katemera wa COVID-19 wovomerezedwa ku India ndi wothandiza motsutsana ndi mitundu ina yaku Britain ya coronavirus yatsopanoyo, koma palibe zambiri pazomwe amachita motsutsana ndi masinthidwe aku South Africa ndi Brazil omwe apezeka mdzikolo. Lachiwiri, Unduna wa Zaumoyo udati anthu anayi adapezeka ndi mtundu waku South Africa wa SARS-CoV-2 ndipo m'modzi adapezeka kuti ali ndi mtundu waku Brazil, woyamba ku India, zomwe zidapangitsa asayansi kutsindika kufunika kowonjezera. deta ndi kafukufuku kuti pulogalamu ya katemera ya dzikolo igwirizane ndi zomwe zikufunika kusintha. Chiwerengero cha anthu omwe adayezetsa zaku UK mdziko muno chakwera kufika pa 187, aboma anawonjezera.
Makatemera omwe avomerezedwa kuti agwiritsidwe ntchito mwadzidzidzi ku India ndi Covishield, wochokera ku khola la Oxford-AstraZeneca lopangidwa ndi Serum Institute of India ku Pune, ndi Covaxin, lopangidwa ndi Bharat Biotech yochokera ku Hyderabad, mogwirizana ndi Indian Council of Medical Research ndi National Institute of Virology (NIV).
Poyankha funso lalikulu m’maganizo mwa anthu ambiri, wofufuza Deepak Sehgal ananena kuti n’zovuta kunena mmene awiriwa adzakhala othandiza polimbana ndi mitundu yatsopano yomwe ikubwera, makamaka ya ku South Africa ndi ku Brazil, pokhapokha asayansi atawaphunzira bwino.
Izi zati, pakati pa katemera awiriwa omwe ali ku India, Covaxin atha kugwira ntchito bwino motsutsana ndi osinthika atsopano chifukwa amapereka chitetezo ku kachilomboka konse. Katemera wa Covishield amayang'ana puloteni imodzi mwa kachilomboka, atero Sehgal, wamkulu wa dipatimenti ya Life Sciences ku Shiv Nadar University, Uttar Pradesh. PTI.
Covaxin, adalongosola kuti, imatha kupanga ma antibodies motsutsana ndi ma epitopes ambiri kapena zigawo zambiri za kachilomboka, pomwe Covishield imapanga ma antibodies kudera linalake la kachilomboka.
Chifukwa chake ngakhale patakhala masinthidwe m'chigawo chimodzi, ma antibodies akupangidwa motsutsana ndi zigawo zina za kachilomboka zomwe zitha kukhala zothandiza pankhani ya Covaxin, anawonjezera.
Covaxin ndi katemera "wosagwira ntchito" wopangidwa pochiza zitsanzo za ma coronavirus atsopano kuti asathe kuberekana. Izi zimasiya mapuloteni a virus osakhazikika, kuphatikiza mapuloteni a coronavirus omwe amagwiritsa ntchito kulowa m'maselo amunthu.
Covishield ili ndi mtundu wopangidwira wa ma adenovirus omwe amapatsira anyani kuti atenge jini yomwe imayambitsa mapuloteni a spike coronavirus yatsopano.
Adenoviruses ndi ma virus omwe nthawi zambiri amayambitsa chimfine kapena matenda a chimfine.
Katemera onsewa amati ali ndi mphamvu motsutsana ndi ku UK.
Malinga ndi kafukufuku yemwe sanasindikizidwe mwa anthu 26, Covaxin idapezeka kuti ikugwira ntchito motsutsana ndi ku UK, Bharat Biotech adatero kumapeto kwa Januware.
Momwemonso, kafukufuku waku University ya Oxford adapeza kuti katemera wa ChAdOx1-nCoV19, wotchedwa Covishield ku India, anali wothandiza kuthana ndi kusiyanasiyana kwa UK.
Katswiri wodziwa za chitetezo chamthupi Vineeta Bal adanenanso kuti kusinthaku ku UK kunali ndi kusintha kumodzi komwe kunali kofunikira ndipo chifukwa chake izi sizinali zodabwitsa.
Ngakhale zotsatira za Bharat Biotech zidadalira zitsanzo zochepa kuti zitsimikizire zoletsa ku kachilombo ka UK muzochitika zomwe zikuchitika, izi zitha kutengedwa ngati chidziwitso chokwanira, adatero Bal waku Indian Institute of Education and Research. Pune Scientist (IISER).
Komabe, mitundu yonse ya ku South Africa ndi Brazil ili ndi masinthidwe ochulukirapo, motero kuchepa kwakukulu kwa magwiridwe antchito kumatha kuwoneka, adatero.
Tilibebe yankho pakuchita bwino motsutsana ndi mitundu yatsopanoyi. Ndili wotsimikiza kuti kuyesayesa kukuchitika kuyesa sera (magazi) kuchokera kwa anthu omwe ali ndi katemera kuti athe kulepheretsa kukula kwa mitundu yatsopano ya chikhalidwe cha minofu, adatero Bal. PTI.
Chifukwa chake, ma virus osinthika ayenera kupezeka komanso kuyika mayeso. Mwachitsanzo, NIV ili ndi luso lochita izi ndipo ndikutsimikiza kuti akuyesera kuyesa, adatero, ndikuwonjezera kuti palibe zotsatira zomwe zilipo pagulu.
Padziko lonse lapansi, katemera 10 wa COVID-19 avomerezedwa ndi mayiko angapo kapena agwiritsidwa ntchito pang'onopang'ono mwadzidzidzi.
Mitundu yatsopano ya coronavirus ikutuluka yomwe ili yopatsirana kuposa yomwe idayambitsa mliri.
Alangizi asayansi ku boma la UK ati mitundu yomwe yafala kwambiri ya COVID-19 mdziko muno ikhoza kukhala "yakufa" 30-70% kuposa mitundu yam'mbuyomu, kutsindika nkhawa za momwe masinthidwe angasinthire mawonekedwe a matendawa.
Kafukufuku waposachedwa akuwonetsa kuti katemera wopangidwa molumikizana ndi chimphona chachikulu chamankhwala ku US Pfizer ndi kampani yaku Germany ya BioNTech atha kuthetsa mitundu ina ya coronavirus yatsopano yomwe idanenedwa koyamba ku UK ndi South Africa.
Kafukufukuyu, yemwe adasindikizidwa mu nyuzipepala ya Nature Medicine, adawona kuti katemerayu amagwira ntchito motsutsana ndi mitundu yosiyanasiyana ya ma coronavirus omwe amanyamula masinthidwe a N501Y ndi E484K.
M'mwezi wa Januware, kampani yaku America yaukadaulo yaku America Moderna idati kafukufuku wa labotale adawonetsa katemera wake wa COVID-19 apitiliza kuteteza ku mitundu ina ya coronavirus yomwe idadziwika koyamba ku UK ndi South Africa.
Komabe, ngati kusamala, kampaniyo iyesa kuwonjezera chowonjezera chachiwiri pa katemera wake, wa jakisoni atatu onse, ndipo yayamba maphunziro a preclinical pa chilimbikitso makamaka cha mtundu waku South Africa.
Mu katemera wa Pfizer ndi Moderna, messenger RNA, kapena mRNA, imakhala ngati pulani yopangira mapuloteni a coronavirus spike ndipo imakutidwa ndi mamolekyu a lipid ndikuperekedwa ku maselo amunthu. Ma RNA ali ndi ndondomeko yopangira mapuloteni m'maselo
M'malo motsatira zomwe zasindikizidwa, zikuwoneka kuti kufalikira kwachangu kwa mitundu yomwe ikubwerayi ingakhale pachiwopsezo kwa anthu omwe achira matenda am'mbuyomu, komanso omwe adalandira katemera kale, adatero Bal.
Ku India, sitikudziwa momwe kuyezetsa, kuzindikira ndi kuika kwaokha kumayendetsedwa moyenera kwa omwe akulumikizana nawo komanso milandu.
Kutengera izi, kufalikira kumatha kuchepetsedwa ndi magwiridwe antchito osiyanasiyana, ndipo mwachiyembekezo palibe kufalikira kwakukulu komwe kudzachitika ndipo kuzungulira kwina sikungakhale kofunikira, anawonjezera.
