COVID-19 Kev Tiv Thaiv Cia Kub Kub: Vim Li Cas ULT Lub Freezer?

Thaum Lub Kaum Ob Hlis 8, Tebchaws Askiv tau dhau los ua thawj lub tebchaws hauv ntiaj teb uas tau pib txhaj tshuaj tiv thaiv pej xeem nrog Pfizer tau pom zoo tag nrho thiab tau soj ntsuam cov tshuaj tiv thaiv COVID-19.Thaum Lub Kaum Ob Hlis 10, Lub Chaw Tswj Xyuas Khoom Noj thiab Tshuaj (FDA) yuav ntsib los tham txog kev tso cai xwm txheej ceev ntawm tib yam tshuaj tiv thaiv.Tsis ntev no, cov teb chaws thoob ntiaj teb yuav ua raws li kev cai, ua cov kauj ruam meej kom nyab xeeb xa ntau lab ntawm cov iav me me no rau pej xeem.

Kev tuav tswj qhov ntsuas kub qis qis uas yuav tsum tau ua kom khaws cov tshuaj tiv thaiv kev ncaj ncees yuav yog qhov kev thauj khoom loj rau cov neeg xa tshuaj tiv thaiv.Tom qab ntawd, ib zaug cov tshuaj tiv thaiv uas tau tos ntev heev thaum kawg mus txog cov chaw muag tshuaj thiab tsev kho mob, lawv yuav tsum tau khaws cia rau hauv qhov kub thiab txias.

Vim li cas cov tshuaj tiv thaiv COVID-19 yuav tsum muaj qhov kub thiab txias?

Tsis zoo li cov tshuaj tiv thaiv kab mob khaub thuas, uas yuav tsum tau khaws cia ntawm 5 degrees Celsius, Pfizer's COVID-19 tshuaj tiv thaiv yuav tsum khaws cia ntawm -70 degrees Celsius.Qhov ntsuas kub qis no tsuas yog kwv yees li 30 degrees sov dua li qhov txias tshaj plaws uas tau sau tseg hauv Antarctica.Txawm hais tias tsis txias heev, Moderna cov tshuaj tiv thaiv tseem yuav tsum tau qis dua xoom kub ntawm -20 degrees Celsius, txhawm rau tswj nws lub zog.

Txhawm rau kom nkag siab qhov xav tau ntawm qhov txias txias, cia peb tshuaj xyuas cov tshuaj tiv thaiv thiab seb cov tshuaj tiv thaiv tshiab no ua haujlwm raws nraim.

mRNA Technology

Cov tshuaj tiv thaiv ib txwm, zoo li mob khaub thuas raws caij nyoog, txog niaj hnub no tau siv cov kab mob tsis muaj zog lossis tsis muaj zog los txhawb kev tiv thaiv kab mob hauv lub cev.Cov tshuaj tiv thaiv COVID-19 uas tsim los ntawm Pfizer thiab Moderna siv messenger RNA, lossis mRNA luv luv.mRNA hloov tib neeg lub hlwb mus rau hauv cov chaw tsim khoom, ua rau lawv tsim cov kab mob coronavirus tshwj xeeb.Cov protein tsim cov tshuaj tiv thaiv kab mob hauv lub cev, zoo li muaj tus kabmob coronavirus tiag tiag.Yav tom ntej, yog tias tus neeg raug tus mob coronavirus, lub cev tiv thaiv kab mob tuaj yeem tua tau yooj yim dua.

mRNA tshuaj tiv thaiv tshuab yog tshiab heev thiab cov tshuaj tiv thaiv COVID-19 yuav yog thawj zaug uas tau pom zoo los ntawm FDA.

Fragility ntawm mRNA

Lub mRNA molecule yog tshwj xeeb tsis yooj yim.Nws tsis siv ntau los ua kom nws tawg.Kev raug rau qhov kub thiab txias tsis zoo lossis cov enzymes tuaj yeem ua rau cov molecule puas.Txhawm rau tiv thaiv cov tshuaj tiv thaiv los ntawm cov enzymes hauv peb lub cev, Pfizer tau qhwv cov mRNA hauv cov npuas roj ua los ntawm lipid nanoparticles.Txawm hais tias muaj kev tiv thaiv npuas, mRNA tseem tuaj yeem ua kom sai sai.Kev khaws cov tshuaj tiv thaiv ntawm qhov kub qis qis tiv thaiv qhov kev puas tsuaj no, ua kom muaj kev ncaj ncees ntawm cov tshuaj tiv thaiv.

Peb Txoj Kev Xaiv rau Kev Cia Tshuaj Tiv Thaiv-19

Raws li Pfizer, cov neeg muab tshuaj tiv thaiv muaj peb txoj kev xaiv thaum nws los khaws lawv cov tshuaj tiv thaiv COVID-19.Cov neeg xa khoom tuaj yeem siv lub freezers ULT, siv cov thermal shippers rau khaws cia ib ntus ntev txog 30 hnub (yuav tsum rov ntim cov dej khov qhuav txhua tsib hnub), lossis khaws cia hauv lub tub yees tshuaj tiv thaiv rau tsib hnub.Cov chaw tsim tshuaj siv tau siv thermal shippers siv cov dej khov qhuav thiab GPS-enabled thermal sensors kom tsis txhob kub excursions thaum taug kev mus rau qhov chaw siv (POU).
