Ibyago byo kwandura Covid byaragabanutse cyane nyuma ya doze ya mbere y’urukingo rwa AstraZeneca cyangwa Pfizer, nk’uko byagaragajwe n’ubushakashatsi mu Bwongereza.
Izi nkingo zarakoze no mu bantu barengeje imyaka 75 ndetse n’abafite izindi ndwara, kimwe no ku bandi bantu.
Ubushakashatsi bubiri bw’ikigo gishinzwe ibarurishamibare hamwe na Kaminuza ya Oxford buvuga ko bwabonye ubwirinzi bw’umubiri bukomeye mu bantu bo mu myaka yose nyuma ya ziriya nkingo.
Bwerekana ibimenyetso ko ziriya nkingo zikoreshwa ahatandukanye mu kurinda abantu kurwara bakazahazwa na Covid-19 ziri gukora no mu kubarinda kwandura coronavirus.
Hari ibigaragaza ko abantu batewe doze imwe ya Oxford-AstraZeneca cyangwa Pfizer-BioNTech ku gipimo cya 65% badashobora gufatwa n’ubwandu bushya bwa Covid.
Kurinda ubwoko bushya
Ibyumweru bitatu nyuma yo gukingirwa, ku barutewe hagati y’ukwa 12/2020 n’intangiriro z’ukwa kane 2021, ubwandu bufite ibimenyetso byagabanutse kuri 74%, mu gihe ubwandu budafite ibimenyetso bwagabanutse kuri 57%.
Ababonye doze ya kabiri y’urukingo rwa Pfizer bo kuri 90% ntibashoboraga kwandura. Ibipimo mu mibare ku bafashe urukingo rwa AZ ntiyashoboraga kuboneka kuko abantu bacye cyane ari bo bari babonye doze ya kabiri.
Ubu bushakashatsi bwerekana ko izi nkingo zombi zikora mu kurinda abantu kwandura ubwoko bushya bwa Covid buzwi nka Kent (B117) buvugwa mu Bwongereza.
Dr Koen Pouwels, umushakashatsi muri kaminuza ya Oxford ishami ry’ubuzima bw’abantu, avuga ko aya makuru ashimangira impamvu y’icyemezo cyo kongera igihe hagati ya doze zombi.
Ati: “Ubwirinzi ku bwoko bushya butangwa na doze ya mbere burashimangira icyemezo cyo kongera igihe hagati ya goze ya mbere n’iya kabiri kikaba ibyumweru 12 kugira ngo habe gukingira benshi bashoboka, no kugabanya abajya mu bitaro n’abapfa.”
Gusa, avuga ko hari imibare yerekana ko abantu bakingiwe bashobora kwandura Covid nanone ndetse bakayanduza abandi, bityo ashimangira ko guhana intera no kwambara udupfukamunwa bigikenewe.
Nubwo ubwirinzi bw’umubiri bwazamutse buhoro kandi ku gipimo gito kuri doze ya mbere ya AstraZeneca, byari bitandukanye nyuma ya doze ya mbere ya Pfizer, cyane cyane mu bantu bakuze.
Kwiyongera kw’ubwirinzi ku barengeje imyaka 80
Ku bahawe doze zombi, habaye ubwirinzi bukomeye ku bantu bagejeje imyaka y’ubukure ugereranyije n’abarengeje imyaka 60, ariko nyuma ya doze zombi za Pfizer ubwirinzi bwari hejuru cyane mu bantu b’imyaka yose, nk’uko ubu bushakashatsi bubivuga.
Kimwe mu byabonywe byatunguye abashakashatsi ni ikigero ubwirinzi bw’umubiri bwazamutseho ku barengeje imyaka 80 nyuma yo guhabwa doze ya kabiri – bwazamutse kurenza abo mu myaka yo hasi.
Ibyabonetse bishimangira akamaro ka doze ya kabiri mu kongera ubwirinzi, nk’uko aba bashakashatsi babivuga.
Gusa ntabwo harasobanuka neza ngo ‘izi nkingo zirinda abantu mu gihe kingana gute.’
Prof Sarah Walker, ukuriye abakoze ubu bushakashatsi, wo muri kaminuza ya Oxford ati: “Ntituramenya neza neza ingano y’ubwirinzi umubiri ukeneye, kandi mu gihe kingana gute, ngo birinde umuntu kwandura Covid mu gihe kirekire – ariko mu mwaka utaha, amakuru azava mu ibarura azadufasha gusubiza ibi bibazo.”
