ʻAʻole e like me nā lāʻau lapaʻau ʻē aʻe i loaʻa i kahi pathogen infectious a i ʻole kekahi hapa o ia mea, hoʻohana nā lāʻau lapaʻau vector i kahi maʻi ʻino ʻole e hāʻawi i kahi ʻāpana o ka genetic code i kā mākou mau cell, e ʻae iā lākou e hana i ka protein o kahi pathogen.Hoʻomaʻamaʻa kēia i kā mākou ʻōnaehana pale e pane i nā maʻi e hiki mai ana.
Ke loaʻa iā mākou ka maʻi bacterial a i ʻole ka maʻi viral, hoʻopili kā mākou ʻōnaehana pale i nā molekala mai ka pathogen.Inā ʻo kā mākou hui mua ʻana me ka mea hoʻouka kaua, e hui pū ʻia nā kaʻina hana e hakakā i ka pathogen a kūkulu i ka pale no nā hālāwai e hiki mai ana.
Hāʻawi ka nui o nā lāʻau lapaʻau kuʻuna i kahi pathogen infectious a i ʻole kekahi ʻāpana o ia mea i ko mākou kino e hoʻomaʻamaʻa i ko mākou ʻōnaehana pale e pale aku i ka hoʻolaha ʻana i ka pathogen.
He ʻokoʻa ka hana o nā lāʻau lapaʻau vector.Hoʻohana lākou i kahi maʻi ʻino ʻole e hāʻawi i kahi ʻāpana o ka genetic code mai kahi pathogen i kā mākou mau cell e hoʻohālike i kahi maʻi.Hana ʻia ka maʻi ʻino ʻole ma ke ʻano he ʻōnaehana lawe, a i ʻole vector, no ke kaʻina genetic.
A laila hana ko mākou mau cell i ka protein viral a i ʻole bacteria i hāʻawi ʻia e ka vector a hōʻike i ko mākou ʻōnaehana pale.
Hāʻawi kēia iā mākou e hoʻomohala i kahi pane kūlohelohe kūʻē i kahi pathogen me ka ʻole o ka loaʻa ʻana o kahi maʻi.
Eia nō naʻe, ke pāʻani nei ka vector viral ponoʻī i kahi hana hou ma ka hoʻonui ʻana i kā mākou pane pale.Ke alakaʻi nei kēia i kahi hopena ʻoi aku ka ikaika ma mua o ka hāʻawi ʻia ʻana o ke kaʻina genetic o ka pathogen iā ia iho.
Ke hoʻohana nei ka lāʻau lapaʻau ʻo Oxford-AstraZeneca COVID-19 i kahi chimpanzee maʻamau maʻamau viral vector i kapa ʻia ʻo ChAdOx1, e hāʻawi ana i ke code e hiki ai i kā mākou mau cell ke hana i ka protein spike SARS-CoV-2.
