Usokhemesti uvula isikhenkcezisi ukulungiselela idosi yePfizer / BioNTech Comirnaty COVID-19 ngoJanuwari 8, 2021 kwindawo yokugcina engachazwanga yesibhedlele iBordeaux CHU ngaphambi kokuba isasazwe kumaziko ogcino ahlukeneyo ale ndawo.I-MEHDI FEDOUACH / AFP ngokusebenzisa imifanekiso kaGetty I-Pfizer kunye ne-BioNTech bangenise idatha entsha kwi-FDA ebonisa ukuba isitofu sabo se-COVID-19 singagcinwa kwiqondo eliqhelekileyo lefriji, endaweni yeemeko ezinqabileyo ezinqabileyo, ukuya kuthi ga kwiiveki ezimbini, ukufunyanwa okuphuculweyo okunokuthi kunciphise kakhulu ukuhanjiswa kokugonya.
Kwisibhengezo sakusasa ngoLwesihlanu, uPfizer uthe idatha yozinzo eveliswe kwiibhotile ezenziwe kwinyanga ezilithoba ezidlulileyo ibonise ukuba isitofu sinokugcinwa kwi -25 ° C ukuya -15 ° C (-13 ° F kuye kwi-5 ° F), amaqondo obushushu aqhelekileyo afunyanwa Kwifriji yamayeza ukuya kuthi ga kwiiveki ezimbini. I-pharma giant iyathemba ukuba i-FDA iyakubandakanya ukufunyanwa kugunyaziso lwe-Emergency Use Authorization (i-EUA), efuna ukugcinwa kubushushu obugqithisileyo phakathi kwe -80ºC kunye -60ºC (-112ºF ukuya ku -76ºF) ngawo onke amaxesha.

Siqokelele ngokuqhubekayo idatha enokuvumela ukugcinwa kwindawo ejikeleze -20 ° C. Idatha engenisiweyo inokuququzelela ukuphathwa kweyeza lethu kwii-pharmacy kwaye inike amaziko okugonya ubhetyebhetye ngakumbi, utshilo u-CEO we-BioNTech u-Ugur Sahin ingxelo .
Besiqhuba ngokuqhubekayo kwizifundo zokuzinza ukuxhasa imveliso yesitofu kwinqanaba lezorhwebo, ngenjongo yokwenza isitofu ukuba sifikeleleke kangangoko kubanikezeli bezempilo nakubantu baseMelika nakwilizwe liphela, utshilo uSihlalo wePfizer kunye ne-CEO u-Albert Bourla a ingxelo . Ukuba ivunyiwe, olu khetho lutsha lokugcina luya kunika iikhemesti kunye namaziko okugonya ukuba bhetyebhetye kwindlela abalawula ngayo unikezelo lokugonya.
Isicwangciso sePfizer kunye neBioNTech sokungenisa ezi datha zozinzo kwiiarhente zolawulo kwihlabathi liphela kwezi veki zimbalwa zizayo.
Ukufunyanwa okutsha kuphakamisa ithemba lokukhutshwa kweyeza lokugonya elikhawulezayo nelitshiphu kwiPfizer kunye neBioNTech. Isitofu sokugonya se-Pfizer-BioNTech COVID-19 saba sesokuqala sokususa isigunyaziso sokusetyenziswa okungxamisekileyo e-US Ngeentsuku zokuqala zokuphuma, uPfizer wadibana nothotho lwezixhobo, kubandakanya ezinye izitofu ezigcinwa kubushushu obugqithisileyo kwaye ezinye zingagcinwa zibanda ngokwaneleyo .

Olunye ugonyo lwe-COVID-19 eligunyazisiweyo e-U.S, olwenziwe nguModerna, lukwafuna ukugcinwa kwikhonkco elibandayo, kodwa kuphela -20 ° C (-4 ° F).
Zombini izitofu zePfizer kunye neModerna zisekwe kwitekhnoloji yemfuza yenoveli eyaziwa ngokuba yi-messenger RNA (mRNA). Moderna utshilo isitofu sayo sokugonya asidingi kugcinwa sibanda njengombulelo wePfizer kwizakhiwo zayo ezikhethekileyo ze-lipid nanoparticle kunye nolwakhiwo. IModerna ikwanamava amaninzi nge-mRNA. Inkampani ivelise iyeza lokuthintela i-mRNA ezilishumi ukuza kuthi ga ngoku.
Phakathi kwePfizer neModerna, malunga ne-1.6 yezigidi zeedosi zokugonya zilawulwa e-US yonke imihla. Njengoko imveliso inyuka kwaye ngaphezulu izitofu zisusa umqobo we-FDA, inqanaba lokugonya kulindeleke ukuba liphindwe kabini kwiiveki ezizayo, ngokwe Uhlalutyo lweBloomberg .
UPfizer kunye noModerna bathembisile ukuhambisa ngaphezulu kwe-500 yezigidi zeedosi e-US ukuphela kukaJulayi. UJohnson noJohnson, ogonyo lwedosi enye liphantsi kokuphononongwa yi-FDA, iceba ukuhambisa iidosi ezili-100 lezigidi ngoJuni.
