ʻO ka wela mālama ʻana o ka maʻi maʻi COVID-19: No ke aha ka ULT Freezer?

Ma ka lā 8 o Dekemaba, ua lilo ʻo United Kingdom i ʻāina mua ma ka honua e hoʻomaka i ka hoʻopaʻa ʻana i nā kamaʻāina me ka lāʻau lapaʻau COVID-19 i ʻae piha ʻia e Pfizer.Ma ka lā 10 o Kekemapa, e hui ka Food and Drug Administration (FDA) e kūkākūkā i ka ʻae ʻana i ka ulia pōpilikia o ka lāʻau lapaʻau like.Ma hope koke iho, e hahai ana nā ʻāina a puni ka honua i ka hoʻopiʻi ʻana, e hana ana i nā hana kūpono e hoʻopakele palekana i nā miliona o kēia mau hue aniani liʻiliʻi i ka lehulehu.

ʻO ka mālama ʻana i nā mahana sub-zero e pono ai e mālama i ka kūpaʻa o ke kano he mea nui ia no nā mea hoʻolaha kano.A laila, i ka hiki ʻana o nā lāʻau lapaʻau i kali lōʻihi ʻia i nā lāʻau lapaʻau a me nā halemai, pono lākou e hoʻomau i ka mālama ʻana i nā mahana sub-zero.

No ke aha e koi ai nā kano COVID-19 i nā wela haʻahaʻa haʻahaʻa?

ʻAʻole like me ka maʻi maʻi influenza, e koi ana i ka mālama ʻana ma 5 degere Celsius, pono ka maʻi maʻi COVID-19 o Pfizer i ka mālama ʻana ma -70 degere Celsius.Ma kahi o 30 degere wale nō kēia mahana ma lalo o ka wela ma mua o nā mahana anu loa i hoʻopaʻa ʻia ma Antarctica.ʻOiai ʻaʻole anuanu loa, koi mau ka lāʻau lapaʻau a Moderna ma lalo o nā mahana ʻole o -20 degere Celsius, i mea e mālama ai i kona ikaika.

No ka hoʻomaopopo pono ʻana i ka pono o nā wela hau, e nānā kākou i nā ʻāpana kano a pehea e hana pono ai kēia mau lāʻau lapaʻau hou.

ʻenehana mRNA

Ua hoʻohana nā lāʻau lapaʻau maʻamau, e like me ka maʻi maʻi maʻi kau, i kēia lā i kahi maʻi nāwaliwali a i ʻole i hoʻohana ʻia e hoʻoulu i kahi pane pale i loko o ke kino.ʻO nā kano COVID-19 i hana ʻia e Pfizer a me Moderna e hoʻohana i ka messenger RNA, a i ʻole mRNA no ka pōkole.Hoʻololi ka mRNA i nā pūnaewele kanaka i nā hale hana, hiki iā lākou ke hana i kahi protein coronavirus kūikawā.Hoʻopuka ka protein i kahi pane kūlohelohe i ke kino, me he mea lā he maʻi coronavirus maoli.I ka wā e hiki mai ana, inā ʻike ʻia ke kanaka i ka coronavirus, hiki i ka ʻōnaehana pale ke hakakā maʻalahi iā ia.

He mea hou loa ka ʻenehana lapaʻau mRNA a ʻo ka maʻi COVID-19 ka mea mua o kāna ʻano e ʻae ʻia e ka FDA.

ʻO ka palupalu o ka mRNA

He palupalu loa ka mole mRNA.ʻAʻole nui ka mea e hoʻopau ai.Hiki ke hoʻopōʻino i ka molekala i ka ʻike ʻana i nā wela a i ʻole nā ​​enzyme.No ka pale ʻana i ke kano mai nā enzymes i loko o ko mākou kino, ua kāʻei ʻo Pfizer i ka mRNA i loko o nā ʻōmole ʻaila i hana ʻia me nā nanoparticles lipid.ʻOiai me ka puʻupuʻu pale, hiki i ka mRNA ke hoʻohaʻahaʻa koke.ʻO ka mālama ʻana i ka lāʻau lapaʻau ma lalo o ka zero e pale ai i kēia haki ʻana, e mālama ana i ka pono o ke kano.

ʻEkolu mau koho no ka mālama ʻana i ka maʻi maʻi COVID-19

Wahi a Pfizer, ʻekolu mau koho i ka wā e mālama ai i kā lākou mau kano COVID-19.Hiki i nā mea hoʻolaha ke hoʻohana i ka ULT freezers, hoʻohana i nā mea hoʻouna wela no ka waiho manawaleʻa a hiki i 30 mau lā (pono e hoʻopiha hou me ka hau maloʻo i kēlā me kēia ʻelima mau lā), a i ʻole e waiho i loko o ka friji no nā lā ʻelima.Ua hoʻonoho ka mea hana lāʻau lapaʻau i nā mea hoʻouna wela e hoʻohana ana i ka hau maloʻo a me nā mea ʻike wela i hiki i ka GPS ke pale aku i nā huakaʻi wela i ka wā e hele ana i kahi o ka hoʻohana (POU).
