Ingabe umthamo owodwa womgomo we-corona wanele??

Imithi yokugomela i-coronavirus yokuqala enikezwa emhlabeni wonke inyuse amathemba empumelelo ekulweni ne-COVID-19, kodwa ochwepheshe manje sebephakamisa ithemba elithe xaxa: Abantu bangadinga kuphela umthamo owodwa esikhundleni sohlobo lwamanje lwemithamo emibili.

Kepha lo mbono udale impikiswano yesayensi, ochwepheshe bethi abukho ubufakazi obanele okwamanje bokuthethelela umthamo owodwa futhi abantu kufanele bahlele ukuthola imithamo emibili.

Imibono evuna ukuhlola umbono womuthi wokugoma wethamo elilodwa yaqiniswa esihlokweni sombono sakamuva ku- iphephandaba I-New York Times kaMichael Mina, udokotela wamasosha omzimba waseHarvard, kanye noZeynep Tufekci, isazi sezokuhlalisana kwabantu esibhale kabanzi ngalesi sifo.

Bacele ukuthi kuqalwe ngokushesha ucwaningo olusha lomtholampilo ukuze kucwaningwe ukuthi umthamo owodwa womuthi wokugoma wanele yini. Bacaphune imininingwane evela ezivivinyweni esezenziwe emithini yokugomela i-Pfizer neModerna ekhombisa ukuvikela kuqale ngemuva komthamo wokuqala, ukusebenza ngempumelelo kwafinyelela cishe ku-90%, uma kuqhathaniswa cishe nama-95% ngemuva kwemithamo emibili.

Kodwa-ke, kuye kwaphakanyiswa imibuzo mayelana nokuthi ukuvikelwa kuzohlala isikhathi esingakanani ngaphandle komthamo wesibili we-booster, kodwa uMina noTawfiqi babhale ukuthi kungenzeka ukuthi udinga umthamo owodwa kufanele uhlolwe ngokushesha.

Ngokwalesi sihloko, “Uma lokhu kuba njalo, lokhu kuzoshintsha umdlalo, okusivumela ukuthi sigome abantu abaningi ngokuphindwe kabili futhi kunciphise kakhulu ukuhlupheka hhayi e-United States kuphela, kodwa nasemazweni lapho ukushoda kwemithi yokugoma ingase ithathe izintambo.” Iminyaka yokuxazulula.

Ingxenye yombuzo, nokho, isasele ukuthi kusebenza kahle kangakanani ukuqhubeka nethamo elilodwa esikhundleni semithamo emibili, noma uhlobo lwethamo elilodwa lungasabalalisa ukuvikelwa kubantu abaningi ngokuphindwe kabili ngesikhathi lapho abantu baseMelika ababalelwa ku-2500 XNUMX befa ngokwesilinganiso igciwane nsuku zonke, ikakhulukazi njengoba imithi yokugoma ingekho endleleni efanele, ukuze itholakale kabanzi izinyanga ezimbalwa.

“Yini esingayenza manje ukuze singabi nabafileyo abangu-60 phakathi nenyanga?” kusho uChristopher Gill, uprofesa wezempilo emhlabeni wonke eBoston University School of Public Health. Waphendula: Kufanele okungenani kube nengxoxo mayelana nokugoma abantu abaningi ngokuphindwe kabili ngomthamo owodwa ngokushesha ngaphandle kokulinda ukuhlolwa okusha. "Uma ulinda, kungenzeka ukuthi ufile."

UScott Gottlieb, owayengukhomishana weFood and Drug Administration (FDA), ungabaze isu labaphathi lokugodla uhhafu wemithamo ukuze baqinisekise ukuthi yanele ukuze wonke umuntu athole umthamo wakhe wesibili, njengoba esimweni esibi kakhulu umthamo owodwa usekhona. okungenani kuhle ngokwengxenye.

UNobhala Womsizi Wezempilo Nezinsizakalo Zabantu uBrett Giroir uthe abaphathi bagcine imithamo eyizigidi ezingama-2.9 ukuthi isebenze njengomthamo wesibili wabantu abayizigidi ezingama-2.9 abazogonywa ngesonto lokuqala kunokuba basebenzise yonke imithamo ngesikhathi esisodwa.

"Siyazi ukuthi umthamo wokuqala uvikela ngokwengxenye, futhi imininingwane ayitholakali njengamanje, ngakho-ke ufuna ukuzama ukukhipha imithamo eminingi ngangokunokwenzeka ukuze unikeze imithamo eminingi ngangokunokwenzeka," uGottlieb, manje oyilungu lenhlangano. Ibhodi labaqondisi bePfizer, lisho ku-CNBC ekuqaleni kwale nyanga. Abantu banezinzuzo ezithile. "

Abanye ochwepheshe, okuhlanganisa nalabo abaseqenjini le-Operation Warp Speed ​​​​kanye ne-FDA, bayaphikisana nalabo abaphakamisa umthamo owodwa esikhundleni semibili, bephawula ukuthi izinyanga zocwaningo olunzulu lwemithi yemithamo emibili zenziwe.

"Umthamo wesibili yingxenye egcwele yomuthi wokugoma uma imigomo ivunyiwe," kusho uMancef Slaoui, umeluleki omkhulu wesayensi ku-Operation Warp Speed, esithangamini nabezindaba. "Kuyandisa ukungatheleleki ezigulini ezibhekene ne-COVID-19, futhi lena idatha ekhombisa ukungatheleleki okuhlala isikhathi eside futhi ngilindele ukuthi izothatha isikhathi eside ngakho-ke abantu akufanele bathathe umuthi wokugoma njengomuthi wokugomela umthamo owodwa."

Nokho, umnyango wawushiywe uvuliwe ukuze kuqhutshekwe nesifundo. Umuntu angabuza umbuzo, kungani zingekho izivivinyo zomthamo owodwa womgomo weModerna noma wePfizer? Lokho kungaba umbuzo osebenzayo futhi vele, isikhathi kuzoba inselele enkulu.
