I-US icebisa "ukuNqumama" kwiJohnson & Johnson COVID-19 Vaccine ngenxa yeXhala leXhala

• Uphengululo lwe

Amaziko oLawulo lweNtsholongwane kunye noThintelo (CDC) kunye noLawulo lwezoKutya kunye noLawulo lweziyobisi (i-FDA) bacebisa ukuba ukulawulwa kwesitofu sokugonya sikaJohnson & Johnson COVID-19 "kuyekiswe" nangona iidosi ezizizigidi ezi-6.8 sele zinikezelwe e-US ukuza kuthi ga ngoku. Iindaba ziza kusetyenziswa ingxelo edibeneyo ebonisa ukuba ababoneleli bezempilo bayayeka ukusebenzisa isitofu sokugonya sikaJohnson & Johnson kude kube kukwazisa.

Esi sincomo sitsha sisiphumo sohlobo olunqabileyo kodwa oluqatha lwehlwili legazi elibizwa ngokuba yi-cerebral venous sinus thrombosis (CVST) elifunyenwe kwabanye abantu abafumene isitofu esithile sokugonya e-US, ngokutsho kwengxelo. Kule meko, "kunqabile" kuthetha ukuba ziimeko ezintandathu kuphela ezichaziweyo zokugonywa kwegazi emva kogonyo kwezi ziphantse zayi-7 yeedosi. Kwimeko nganye, i-clot yegazi yabonwa ngokudibanisa ne-thrombocytopenia, aka amanqanaba asezantsi egazi (iziqwenga zeseli egazini lakho ezivumela umzimba wakho ukuba wenze amahlwili ayeke okanye athintele ukopha). Ukuza kuthi ga ngoku, iimeko ezixeliweyo kuphela ze-CVST kunye ne-thrombocytopenia kulandela isitofu sokugonya sikaJohnson & Johnson sele sikwabafazi abaphakathi kweminyaka eli-18 ukuya kuma-48, kwiintsuku ezi-6 ukuya kwezi-13 emva kokufumana iyeza lonyango olunye, ngokwe-FDA kunye neCDC.

I-CVST luhlobo lwesifo esinqabileyo, ngokukaJohns Hopkins Medicine. (ICYDK, ukubethwa sisibetho kuchaza imeko apho "ukunikezelwa kwegazi kwinxalenye yengqondo yakho kuphazanyiswa okanye kuncitshisiwe, kuthintela izicwili zobuchopho ekufumaneni ioksijini kunye nezakhamzimba," ngokweKliniki yaseMayo.) ii-venous sinuses zobuchopho (iipokotho eziphakathi kweyona maleko engaphandle yobuchopho), nto leyo ethintela igazi ekumpompozeni ebuchotsheni. Xa igazi lingakwazi ukukhupha, ukuphuma kwegazi kunokubangela, oko kuthetha ukuba igazi linokuqalisa ukuvuza kwizicwili zobuchopho. Iimpawu zeCVST zibandakanya intloko, ukungaboni kakuhle, ukuphelelwa ngamandla okanye ukulahleka kwengqondo, ukuphulukana nolawulo lokuhamba, ukuxhuzula, kunye nokudinwa, ngokukaJohn Hopkins Medicine.

Ngokunikwa inani eliphantsi leengxelo zeCVST kubo bonke abantu abafumene isitofu sokugonya sikaJohnson & Johnson COVID-19, usenokuzibuza ukuba ingaba impendulo ye-CDC kunye ne-FDA yinto egqithisileyo. Inyaniso yokuba ii-clots zegazi kunye neeplatelet ezisezantsi zenzeka ngokudibeneyo yile nto yenza ukuba la matyala aphawuleke, utshilo uPeter Marks, MD, Ph.D., umlawuli weZiko le-FDA loVavanyo lweBiologics noPhando, kwindibano yeendaba. “Kukwenzeka kwabo kunye okwenza ipateni kwaye le pateni ifana kakhulu naleyo yabonwa eYurophu nesinye isitofu,” utshilo. Kusenokwenzeka ukuba uGqirha Marks ubhekise kwisitofu sokugonya se-AstraZeneca, enikwe iindaba zokuba amazwe amaninzi ase-Yuropu anqumle ngokufutshane ukusebenzisa kwabo isitofu kwinyanga ephelileyo ngenxa yeengxelo zokugubungela igazi kunye neeplatelets ezisezantsi.

Ngokwesiqhelo, isiyobisi esijiwayo ekuthiwa yi-heparin sisetyenziselwa ukunyanga amahlwili egazi, ngokwe-CDC kunye ne-FDA's ingxelo edibeneyo. Kodwa i-heparin inokubangela ukwehla kwamanqanaba eplatelet, ke kunokuba yingozi xa isetyenziselwa ukunyanga abantu abasele benenani eliphantsi leplatelet, njengakwimeko yabasetyhini abathandathu abanemicimbi yeJ & J. Ukuphelisa ukusetyenziswa kweyeza lokugonya ngumzamo "wokuqinisekisa ukuba ababoneleli bayazi ukuba xa bebona abantu abanegazi elinegazi eliphantsi, okanye ukuba babona abantu abanamahlule egazi, kufuneka babuze malunga nembali yogonyo lwamva nje kwaye emva koko benze ngokufanelekileyo kuxilongo kunye nolawulo lwabo bantu, utshilo uGqr Marks ngexesha lengcaciso.

Kubalulekile ukuqaphela ukuba ngenxa yokuba i-CDC kunye ne-FDA icebisa "unqumamo" ayithethi ukuba ulawulo lwesitofu sokugonya sikaJohnson & Johnson luya kunqunyanyiswa ngokupheleleyo. "Sincoma ukuba isitofu sinqunyanyiswe ngokwemiqathango yolawulo lwaso," utshilo uGqirha Marks ngexesha lengcaciso. "Nangona kunjalo, ukuba umboneleli wezempilo ngamnye unencoko kunye nesigulane ngasinye kwaye banqume ukuba inzuzo / umngcipheko wesigulane eso sifanelekile, asiyi kummisa loo mnikezeli ekulawuleni isitofu sokugonya." Izibonelelo ziya kudlula umngcipheko "kuninzi lwamatyala," wongeze watsho.

Ukuba ungomnye wezigidi zabantu baseMelika abasele befumene isitofu sokugonya sikaJohnson noJohnson, ungoyiki. "Kubantu abafumene iyeza lokugonya ngaphezulu kwenyanga ephelileyo, umngcipheko usezantsi kakhulu ngeli xesha," utshilo u-Anne Schuchat, MD, umlawuli oyintloko we-CDC, nakule ngxelo yeendaba. "Kubantu abasandula ukufumana iyeza kwisithuba seeveki ezimbalwa ezidlulileyo, kufanele ukuba bazi ukuba bajonge naziphi na iimpawu. Ukuba ufumene isitofu kwaye ukhula nentloko ebuhlungu, iintlungu zesisu, iintlungu zomlenze, okanye ukuphefumla kancinci, kufuneka unxibelelane umboneleli ngenkathalelo yezempilo kwaye ufuna unyango.

Ulwazi kweli bali luchanekile ngexesha lokushicilelwa. Nangona kunjalo, njengoko imeko ejikeleze i-COVID-19 iqhubeka nokuvela, kunokwenzeka ukuba idatha ethile itshintshile ukusukela oko yapapashwa. Ngelixa iMpilo izama ukugcina amabali ethu ehlaziywa ngokusemandleni, sikwakhuthaza abafundi ukuba bahlale benolwazi ngeendaba kunye neengcebiso kuluntu lwabo ngokusebenzisa i-CDC, i-WHO, kunye nesebe labo lezempilo likarhulumente lendawo njengezixhobo.
