Ingabe imithi yokugoma inikeza ukugonywa iminyaka eminingi?

Ingabe imithi yokugoma inikeza ukugonywa iminyaka eminingi?

Ngenxa yamagagasi okushintshashintsha kwe-corona emhlabeni wonke kanye nokwanda kwesibalo sabantu abangenwa izifo, ucwaningo lwakamuva luveze ukuthi imigomo emibili ye-Pfizer kanye nozakwabo “i-Bionic”, ngaphezu kwe-Moderna, inganikeza isivikelo egciwaneni leCorona iminyaka. noma ngisho ukuphila.

Ucwaningo lwase-US luthole ukuthi abantu abaningi abagonywe ngemithi yokugomela i-mRNA kungenzeka bangadingi imithamo eyengeziwe ye-booster, inqobo nje uma igciwane nezinhlobo ezintsha zalo zingaguquki kakhulu.

"Kuwuphawu oluhle lokusimama kokugoma kwethu sisebenzisa lo mgomo," kusho u-Ali Al-Yaidi, umphathi wocwaningo kanye nomsizi kaprofesa eYunivesithi yaseWashington eSt. Louis, ngokusho kwacashunwa "New York Times."

Amasosha omzimba ayimfihlo

Udokotela nozakwabo ocwaningweni bathole ukuthi amaseli omzimba abona leli gciwane ahlala emizimbeni yabantu abeluleme ku-corona okungenani izinyanga eziyisishiyagalombili ngemuva kokutheleleka.

Futhi, ucwaningo olwenziwa elinye ithimba lubonise ukuthi amangqamuzana abizwa ngokuthi "inkumbulo B" ayaqhubeka nokuvuthwa futhi aqine okungenani unyaka ngemva kokutheleleka.

Ocwaningweni olusha, ososayensi baphakamise ukuthi ukungatheleleki kuzohlala iminyaka, futhi mhlawumbe impilo yonke, kubantu ababengenwe yileli gciwane futhi bagonywa kamuva, kodwa akuzange kucace kubo ukuthi ukugoma kukodwa kungaba nalo mphumela wesikhathi eside, efana nalabo ababenalesi sifo ngaphambili.

Ngakho-ke, iqembu labheka umthombo wamangqamuzana enkumbulo, ama-lymph nodes, lapho la mangqamuzana omzimba omzimba eqeqeshelwa ukubona nokulwa naleli gciwane.

Bathola ukuthi ngemva kokutheleleka noma ukugonywa, isakhiwo esibizwa ngokuthi i-germinal centre yakheka kuma-lymph nodes. Kulesi sakhiwo, amaseli aqeqeshwe ngokuqinile ukulwa negciwane.

Uma la maseli eziqeqesha isikhathi eside, maningi amathuba okuthi amise izinhlobo zegciwane ezingase ziqhamuke.

Ukuthuthukiswa kwama-B-cell kuvikela ngokumelene negciwane

Ngokufanayo, uMarion Pepper, udokotela wamasosha omzimba eNyuvesi yaseWashington eSeattle, uchaze ukuthi wonke umuntu uhlale egxile ekuziphendukeleni kwegciwane, ephawula ukuthi lolu cwaningo lukhombisa ukuthi “amangqamuzana amasosha omzimba B nawo ayavela, okusho ukuthi le ntuthuko eqhubekayo izovela. vikela igciwane.”

Ngesikhathi socwaningo, ithimba lacwaninga imininingwane yabantu abangu-41, okuhlanganisa abayisishiyagalombili abanomlando wokutheleleka ngegciwane, futhi bonke bagonywe ngemithamo emibili yomgomo we-“Pfizer”, futhi ithimba lathatha amasampula kuma-lymph nodes. Abantu abayi-14 ngemuva kwamasonto amathathu, amane, amahlanu, ayisikhombisa nayi-15 ngemuva komthamo wokuqala.

Abacwaningi bathola ukuthi emasontweni ayi-15 ngemuva komthamo wokuqala womgomo, isikhungo samagciwane sisasebenza kakhulu kubo bonke ababambiqhaza abangu-14, nokuthi inani lamaseli enkumbulo "B" aqaphele igciwane alizange lehle.

Ngaphezu kwalokho, u-Al Yabidi wachaza ukuthi "ukuqhubeka kwempendulo cishe izinyanga ezine ngemuva kokugoma kuwuphawu oluhle kakhulu," njengoba izikhungo ze-microbial ngokuvamile zifinyelela inani eliphakeme emasontweni amabili kuya kwamabili ngemva kokugoma bese ziphela.

Abantu abadala kanye nabantu abakhubazekile badinga ama-booster

Ngokwakhe, uDipta Bhattacharya, udokotela wamasosha omzimba eNyuvesi yase-Arizona, uthe izikhungo zamagciwane ezigqugquzelwe imigomo ye-"mRNA" ziqhubekile nokusebenza ezinyangeni ngemuva kokwenzeka kwayo.

Ugcizelele ukuthi ukubaluleka kwalolu cwaningo kulele ekutheni okuningi ososayensi abakwaziyo ngokuqhubeka nokuba khona kwezikhungo ezinamagciwane kususelwa ocwaningweni ngezilwane, kanti lolu cwaningo luqala kubantu.

Imiphumela ikhomba ukuthi iningi labantu abagonyiwe bazoba nokugonywa okungenani isikhathi eside ezinhlobonhlobo zamanje ze-coronavirus.

Kodwa abantu abadala asebekhulile, abantu abanamasosha omzimba abuthakathaka, nalabo abathatha imishanguzo ecindezela amasosha omzimba bangase badinge ama-booster.

Ngokuqondene nabantu abeluleme egciwaneni futhi bagonyiwe, bangase bangawadingi nhlobo, njengoba amazinga abo amasosha omzimba enyuka ngenxa yokuthi amaseli enkumbulo “B” ayekhula ngaphambi kokugonywa.

Ucwaningo luveze ukuthi kunzima ukubikezela ubude besikhathi sokugoma kusetshenziswa imigomo ye-mRNA, kodwa uma kungekho zinkinga ezingabalekela ukungatheleleki, kuyenzeka ngokwengqondo ukuthi uqhubeke impilo yonke.
