Tshaj li ntawm ob peb hnub, kev nyab xeeb thiab ua tau zoo ntawm cov neeg xa xov lna, lossis mrna, txhaj tshuaj tiv thaiv tau los hauv qab scrutiny.
Hnub Tuesday, U.S. Kev Tswjhwm Saib Xyuas Zaub Mov thiab Tshuaj Yeeb Tshuaj yuav txwv tsis pub nkag mus rau yav tom ntej Ob tug uas yog MRNA txhaj tshuaj tiv thaiv -- rau cov laus 65 thiab laus dua lossis nrog siab - pheej hmoo. Lub chaw haujlwm yuav xav tau kev sim tshawb fawb ntxiv mus rau lub teeb rau cov hnub nyoog rau cov hnub nyoog yau.
Lub chaw haujlwm tseem xa cov tsiaj ntawv rau ob lub hlis tshiab thiab Pfizer lub hli tas los nthuav qhia cov neeg uas yuav muaj kev pheej hmoo ntawm lub plawv ua tau.
Cov kws tshuaj tiv thaiv kab mob kis tau tias MRNA thiab MRNA cov tshuaj tiv thaiv tau kawm tau zoo thiab ua tau zoo, thiab cov tshuaj tiv thaiv no tau ua tau zoo thiab ua tau zoo, thiab cov tshuaj tiv thaiv tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj txhaj tau zoo, thiab cov tshuaj tiv thaiv no tau ua rau txuag lub neej thaum lub sijhawm
"Ntawm no yog cov tshuaj tiv thaiv hauv qab: MRA txhaj tshuaj tiv thaiv rau kev kwv yees, tau txais kev zam txim rau ABLOR tsev kawm ntawv hauv Hoteton, hais rau ABC Xov Xwm.
"Yog li hloov 1.2 lab Asmeskas uas poob lawv lub neej vim yog covid, nws yuav yog 4.4 lab," nws ntxiv. "Yog li, Kuv xav tias nws tsis muaj hmoo tias anti - Cov tshuaj tiv thaiv kev tiv thaiv mRA zoo li lawv ua, tab sis nws yog lub thev naus laus zis zoo."
MRNA yog dab tsi?
MRNA tau nrhiav pom ntawm nws tus kheej los ntawm ob pab pawg hauv xyoo 1961 suav nrog Fabkis thiab American molecular biologist.
Dr. Peter Chin - Hong, yog tus xibfwb qhia tshuaj thiab kis tau tus kabmob MRA, San Francisco tau pib thaum ntxov 2000,, cov tshuaj tiv thaiv hauv 2020.
Thaum cov tshuaj tiv thaiv feem ntau siv tus kab mob uas tsis muaj zog lossis tsis muaj zog los txhawb kev tiv thaiv kab mob mermune qhia tau tias yuav ua rau cov tshuaj tiv thaiv kab mob mws uas tuaj yeem tawm tsam tus kab mob.
"Txoj kev uas nws ua haujlwm yog tias nws tsis txawm mus rau hauv lub nucleus [ntawm lub cncleusc, thiab cia li qhia lub cncleus," puab tsaig sab nraud ua kom cov protein, "puab tsaig - Hong qhia ABC News. "Tab sis qhov tseem ceeb tshaj plaws, nws tus kheej - puas tsuaj rau teeb meem, nyob rau ntawm feem ntau hnub, thiab nws tuag."
Nws txuas ntxiv, "yog li mRNA ploj mus, tab sis cov khoom uas tseem ceeb tshaj plaws -- cov protein thiab cov tshuaj tiv thaiv -- yog vim li cas peb tau txais kev tiv thaiv."
Siv lub puab tsaig - hong tseem nyob ntxiv lwm qhov kev tsis raug uas tau ncig ua ke, ua rau cov tshuaj tiv thaiv mRA tuaj yeem hloov DNA hauv cov nucleus.
"Peb cov cell tsis tau hloov MRNA vim tias MRNA tsis nkag DNA, uas yog nyob rau hauv lub nucleus," nws ntxiv.
Ua li cas peb thiaj paub tias nws muaj kev nyab xeeb?
Lub puab tsaig - Hong tau hais tias thaum lub sij hawm loj - nplai kev sim siab rau kev sim, hauv 2020, ntau dua 70,000 tus neeg tau koom nrog hauv Pfizer - Biontets ua ke.
Tsis tas li ntawd, 37,000 tus neeg tau koom nrog Modan cov tshuaj ntsuam xyuas rau nws cov tshuaj tiv thaiv RSV rau nws RSV txhaj tshuaj, puab tsaig - tus neeg siab hais.
Cov kws tshawb nrhiav pom tias kev phiv -- Xws li kub taub hau, caj npab mob thiab o ntawm qhov chaw txhaj tshuaj -- Rau cov lus qhia - 19 mRA zoo li cov tsoos, tsis muaj tshuaj tiv thaiv thiab lawv muaj luv luv nqi ntawm ntau dua 90%.
Cov kev tshawb fawb ntxiv tau pom tias kev tiv thaiv kev nyab xeeb tau zoo sib xws nrog kev nyab xeeb rau kev txhaj tshuaj tiv thaiv thawj.
"Muaj tag nrho cov databases uas tau siv los ua raws li cov lus qhia ntawm cov neeg, tsis yog nyob rau lwm lub tebchaws, ntau lub tebchaws thiab lwm lub tebchaws thiab," "Muaj ntau txoj kev tshawb fawb txij li 2020 uas qhia tias tsis muaj kev cuam tshuam rau kev muaj peev xwm, mob stroke, txhua yam uas tib neeg tau txhawj txog."
Hotez tau hais tias tsis muaj tshuaj tiv thaiv kab mob yog zoo meej, tab sis nws muaj nws cov txiaj ntsig zoo li muaj peev xwm tau txais kev txhaj tshuaj sai dua, tso cai rau kev tshem tawm sai.
Nws tsis pom zoo nrog kev txiav txim siab FDA los txwv yav tom ntej
"Kuv xav tias muaj ntau tus neeg hluas, lossis cov neeg muaj kev txhawj xeeb ntev txog cov tshuaj uas xav tau txoj kev xav tau lub plawv MRN," nws tau hais.
Yuav ua li cas hais txog myocarditis?
Cov lus nug muaj yi yaig ncig yuav ua li cas mycoritis, uas yog o ntawm lub plawv cov leeg, tshwm sim tom qab lub zos - 19 Txhaj tshuaj tiv thaiv.
MySocarditis tuaj yeem ua rau Arrhythmias, uas yog lub plawv dhia ceev lossis txawv txav. Nws kuj tseem tuaj yeem ua rau lub plawv ua kom tsis muaj zog, ua rau lub plawv dhia, uas cuam tshuam rau lub siab muaj peev xwm nqus ntshav.
Cov kab mob ntawm myocarditis -- Cov mob o ntawm cov hnab uas muaj lub siab -- tau pom tsis tshua muaj tom qab kev txhaj tshuaj tiv thaiv lub hau? Cov chaw rau tus kab mob kev tswj hwm thiab kev tiv thaiv.
Thaum lawv tsis tshua muaj tshwm sim, nws tau nyob ntawm cov tub ntxhais hluas cov neeg laus 18 thiab 29, tsis pub dhau xya hnub tom qab tau txhaj koob tshuaj thib xya, lub chaw haujlwm hais.
Lub FDA, hauv kev nug cov tuam txhab txhaj tshuaj tiv thaiv kom nthuav lawv cov ntawv ceeb toom, hais txog "cov ntaub ntawv kev nyab xeeb tshiab" -- cov ntaub ntawv los ntawm ib qho ntawm lub koom haum kev nyab xeeb kev soj ntsuam cov kab ke thiab ib Txoj kev kawm ntawv tshaj tawm thaum Lub Kaum Hli Cov neeg ua raws cov neeg uas tau tsim myocarditis txuas rau txoj kev txhaj tshuaj txhaj.
Chin - Hong tau hais tias kev pheej hmoo ntawm MySocarditis yog ntau dua tom qab kev sib tshuaj - 19 piv rau cov tshuaj tiv thaiv, thiab kev cog lus hlua nws tus kheej siab dua.
Txoj kev pheej hmoo ntawm cov lus yog qhov siab dua. Yog koj saib nws, 22 rau 31 txog 29 xyoos piv txwv li, "nws hais. "Lub sijhawm uas cov tshuaj tiv thaiv no tau siv ntau zaus nyob rau hauv pab pawg ntawd, [MyScarditis txoj kev pheej hmoo] yog, koj hais lus txog 22,500 ib lab."
Nco tseg: luam tawm los ntawmABC Xov Xwm 'Koji Benadjaoud muaj txiaj ntsig rau daim ntawv tshaj tawm no.
