Ngaba idosi enye yesitofu sokugonya se-corona yanele??

Izitofu zokuqala zokugonya ze-coronavirus ezenziwa kwihlabathi liphela ziphakamise ithemba lempumelelo kumlo ochasene ne-COVID-19, kodwa iingcali ngoku ziphakamisa ithemba elithe kratya: Abantu banokufuna idosi enye endaweni yerejimeni yangoku yedosi ezimbini.

Kodwa lo mbono ubangele impikiswano yesayensi, iingcali zithi akukho bungqina baneleyo okwangoku bokuthethelela idosi enye kwaye abantu mabacwangcise ukufumana ezimbini.

Izimvo ezixhasa ukuphonononga umbono wesitofu sokugonya sedosi enye zacaciswa kwinqaku loluvo lwamva nje iphephandaba INew York Times kaMichael Mina, ugqirha wamajoni omzimba kwiYunivesithi yaseHarvard, kunye noZeinab Tawfiqi, isazi ngezentlalo esibhale kakhulu ngesi sifo.

Kwaye baye bacela ukuqalisa kwangoko kolingo olutsha lweklinikhi ukufunda ukuba idosi enye yesitofu sokugonya yanele na. Bacaphula idatha kulingo esele lwenziwe ngogonyo lwe-Pfizer kunye neModerna olubonise ukhuseleko oluqalwe emva kwethamo lokuqala, olusebenzayo ukuya kuthi ga kwi-90%, xa kuthelekiswa malunga ne-95% emva kweedosi ezimbini.

Nangona kunjalo, imibuzo yaphakanyiswa malunga nokuba ukhuseleko luya kuhlala ixesha elingakanani ngaphandle kwedosi yesibini ye-booster, kodwa uMina noTawfiqi babhala ukuba ithuba lokufuna idosi enye ye-booster kufuneka liqwalaselwe kwangoko.

Ngokutsho kweli nqaku, “Ukuba oku kungqineke kunjalo, kuya kuba kutshintsha umdlalo, okusivumela ukuba sigonye ngokuphindwe kabini abantu abaninzi kwaye sinciphise kakhulu ukubandezeleka kungekuphela eUnited States, kodwa nakumazwe apho ukunqongophala kwesitofu sokugonya. kungathatha iminyaka ukusombulula.

Nangona kunjalo, inxenye yombuzo isala ukuba iya kusebenza kangakanani na ukuqhubela phambili ngedosi enye kunokuba ibe zimbini nangona idosi yedosi enye ingasasaza ukhuseleko ukuphinda kabini inani labantu ngexesha apho malunga nama-2500 XNUMX abantu baseMelika ngokomndilili babulawa yintsholongwane. yonke imihla, ngakumbi njengoko izitofu zokugonya zingekho kumkhondo ochanekileyo Ukuze zifumaneke ngokubanzi kangangeenyanga ezininzi.

UChristopher Gill, unjingalwazi wezempilo yehlabathi kwiBoston University School of Public Health uthi: “Sinokwenza ntoni ngoku ekubeni singekafi abantu abangama-60 XNUMX ngenyanga nje?” Kwaye uphendule wathi: Kufuneka ubuncinane kubekho ingxoxo malunga nokugonya abantu abaninzi ngedosi enye ngokukhawuleza ngaphandle kokulinda ulingo olutsha. Kwaye ukuba uyalinda, usenokuba ufile.”

UScott Gottlieb, owayesakuba ngumkomishinala woLawulo lokuTya kunye neDrugs (i-FDA), uye wabuza isicwangciso solawulo sokubamba isiqingatha seedosi ukuqinisekisa ukuba kukho okwaneleyo ukuze wonke umntu afumane idosi yakhe yesibini, kuba kwiimeko ezimbi kakhulu idosi enye isekhona. ubuncinci isohlwayo.

Unobhala oNcedisayo wezeMpilo kunye neeNkonzo zoLuntu uBrett Giroir uthe ulawulo lubhukisha i-2.9 yezigidi zeedosi ukuba zisebenze njengedosi yesibini yabantu abazizigidi ezi-2.9 abagonywe kwiveki yokuqala kunokuba basasaze zonke iidosi kanye.

Siyazi ukuba idosi yokuqala ikhusela ngokuyinxenye, kwaye idatha ayifumaneki ngoku, ke ufuna ukuzama ukutyhala iidosi ezininzi kangangoko unakho ukunika iidosi ezininzi kangangoko kunokwenzeka,” uGottlieb, ngoku olilungu lebhodi yePfizer. yabalawuli, uxelele i-CNBC ekuqaleni kwale nyanga.

Ezinye iingcali, kubandakanywa nezo zikwi-Operation Warp Speed ​​​​team kunye ne-FDA, ziyachasa abo bacebisa idosi enye kunezimbini, bephawula ukuba iinyanga zokuphononongwa ngononophelo kwerejimeni yeedosi ezimbini zenziwe.

"Idosi yesibini yinxalenye epheleleyo yesitofu sokugonya ukuba izitofu zivunyiwe," utshilo uMancef Al-Salawi, umcebisi oyintloko wesayensi kwi-Operation Warp Speed, kwinkomfa yabezindaba. Yongeza ukungakhuseleki kwizigulana ngokuchasene ne-COVID-19, kwaye le yidatha ebonisa ukungagungqi kwexesha elide kwaye ndilindele ukuba ibe lixesha elide ukuze abantu bangasithathi isitofu sokugonya njengesitofu sedosi enye. ”

Noko ke, walushiya ucango luvuliwe ukuze aqhubeke nesifundo. Umntu unokubuza umbuzo, kutheni amalingo engenziwa ngedosi enye yeModerna okanye iPfizer? Lowo iya kuba ngumbuzo osebenzayo, kwaye ewe, ixesha liya kuba ngumngeni omkhulu.
