Chikamu-chechipiri chekiriniki yekuyedza yeCCIDID-19 mukwikwidzi wekudzivirira akagadzirwa neAcademy of Military Medical Sayenzi uye kambani yeChinese biotech CanSino Biologics yakaona kuti yakachengeteka uye inogona kuunza mhinduro yezvirwere zvemuviri, sekureva kwetsvakiridzo yakaburitswa muThe Lancet medical magazine on. Muvhuro.
Zvakare nemusi weMuvhuro, The Lancet yakaburitsa mhedzisiro yechikamu chekutanga uye chikamu-chechipiri chekiriniki yekuedzwa yeadenovirus vectored vaccine yakagadziriswa nesainzi kuOxford University uye biotech kambani AstraZeneca.Mushonga uyu wakaratidzawo kubudirira mukuchengetedza uye potency kurwisa COVID-19.
Nyanzvi dzakadana mhedzisiro iyi "inovimbisa".Zvisinei, mibvunzo inomanikidzira inoramba iripo, yakadai sehupenyu hurefu hwekudzivirirwa kwayo, muyero wakakodzera wekukonzera mhinduro yakasimba yekudzivirira zvirwere uye kana paine misiyano yakananga yevaenzi sezera, bonde kana dzinza.Iyi mibvunzo ichaongororwa mune yakakura chikamu-yechitatu miedzo.
Mushonga weadenovirus vectored vaccine unoshanda nekushandisa hutachiona husina simba hunozivikanwa kuunza genetic zvinhu kubva painoveli coronavirus mumuviri wemunhu.Pfungwa ndeyekudzidzisa muviri kugadzira masoja ekudzivirira chirwere anoziva coronavirus spike protein uye kuirwisa.
Muchikamu chechipiri chekuedza kwekudzivirira kweChinese, vanhu mazana mashanu nevasere vakatora chikamu, mazana maviri nemakumi mashanu nevatatu vavo vachiwana mushonga wakakwira wejekiseni, zana nemakumi maviri nepfumbamwe dosi yakaderera uye 126 placebo.
Makumi mapfumbamwe neshanu muzana evatori vechikamu muboka redosi yepamusoro uye 91 muzana muboka redosi yakaderera vaive neT-cell kana antibody immune immune mazuva makumi maviri nemasere mushure mekugamuchira vaccine.T-masero anogona kunanga zvakananga nekuuraya utachiona hunopinda, huchiita chikamu chakakosha chemhinduro yekudzivirira kwemuviri wemunhu.
Vanyori vakasimbisa, zvisinei, kuti hapana vatori vechikamu vakaoneswa tsvakiridzo yekoronavirus mushure mekudzivirira, saka zvichiri kukurumidza kutaura kana mumiriri wekudzivirira anogona kudzivirira nekudzivirira kubva kuCOVID-19 kutapukira.
Kana zviri zvekukonzeresa, fivha, kuneta uye kurwadza kwejekiseni-panzvimbo yaive mamwe emhedzisiro yaizivikanwa yekudzivirira kweChinese, kunyangwe mazhinji ekuita uku aive akapfava kana pakati.
Imwe caveat yaive yekuti nevector yekudzivirira iri hutachiona hunotonhora, vanhu vanogona kunge vaine preexisting immune immune inouraya mutakuri wehutachiwana musati watanga kushanda, izvo zvinogona kukanganisa zvishoma mhinduro dzemuviri.Kuenzaniswa nevanhu vadiki, vatori vechikamu vakura kazhinji vaive nemhinduro dzakadzikira dzekudzivirira zvirwere, chidzidzo chakawana.
Chen Wei, akatungamira basa rekudzivirira, akataura mukuburitswa kwenhau kuti vanhu vakura vangangoda imwe dosi kuti vape simba rekudzivirira zvirwere, asi kumwe kutsvagisa kunozodiwa kuongorora nzira iyi.
CanSino, mugadziri wejekiseni, ari muhurukuro dzekutangisa nhanho-nhatu munyika dzinoverengeka dzekunze, Qiu Dongxu, director director uye co-muvambi weCanSino, akadaro pamusangano muSuzhou, mudunhu reJiangsu, neMugovera.
Chinyorwa chinoperekedza muThe Lancet pazvidzidzo zviviri zvevaccine zvichangoburwa zvakadaidza mhedzisiro yemiedzo kubva kuChina neUnited Kingdom "yakafanana uye inovimbisa".
