M'masiku angapo apitawa, chitetezo ndi chidwi cha Merna, kapena MRNA, katemera wabwera mwachangu.
Lachiwiri, iwe. Awiri omwe ali Mrna Katemera -- Kwa azaka 65 ndi okulirapo kapena ndi okwera - mikhalidwe yoopsa. Bungweli likufuna mayesero ena asayansi ogonjetsera kuwombera kwa achinyamata.
Bungweli linatumizanso makalata kwa onse a Anderna ndi PFizani mwezi watha kuwauza kuti achulukitse machenjezo awo a Mrna Covid - Katemera wa 19 kuti apititsetse anthu omwe angakhalepo ndi vuto lalikulu.
Akatswiri azachuma atauza ABC ndipo a Mrna ndi katemera ali otetezeka komanso othandiza, ndipo kuwombera kumathandizanso kupulumutsa anthu pa Covird - 19 Mliri.
"Pano pali chomangira: Mrna Katemera wa ku Covid, malinga ndi kuyerekezera kuchokera ku sukulu yakale ya Health Health," Dr. Peter, a ABC News.
"Chifukwa chake m'malo mwa anthu aku America mamiliyoni awiri omwe adataya moyo chifukwa cha Covid, akadakhalapo mamiliyoni 4.4," anawonjezera. "Chifukwa chake, ndikuganiza kuti ndi zoyipa kuti anti - Othandizira katemera amakwaniritsa makatemera a mrna monga momwe amachitira, koma ndi ukadaulo wabwino."
Kodi MRNA ndi chiyani?
MRNA adapezeka palokha ndi magulu awiri mu 1961 kuphatikizaponso mawotchi achi French.
Dr. Chin Chin - Hong, pulofesa wamankhwala opatsirana ku Yunivesite ya California, San Francisco adayamba ku Circines, pambuyo pake katemera 1920.
Ngakhale katemera wambiri umagwiritsa ntchito virus yofooka kapena yolimbitsa chitetezo chathupi, katemera wa MRNA amaphunzitsa matebulo momwe angapangire mapuloteni omwe angayambitse kuyankha kwathupi ndikulimbana ndi matenda.
"Momwe zimagwirira ntchito ndikuti sizimapita mu nyukiliya [mwa khungu] "Koma koposa zonse, izi ____ net netch. Masiku ambiri, ndipo imafa."
Anapitiriza, "Chifukwa chake MRNA amachoka, koma zinthu zomwe ndi chinthu chofunikira kwambiri -- Mapuloteni ndi ma antibodies -- Khalani, ndipo ndichifukwa chake timatetezera."
Chin - Hong adanenanso za mabodza ena omwe amafafaniza kuti katemera wa MRNA akhoza kusintha DNA mu nyukiliya.
"Maselo athu sangathe kuteteza Mrna ku DNA chifukwa MRNA salowa mu DNA, yomwe ili mu nyukiliya," adanenanso.
Kodi tikudziwa bwanji kuti ndiotetezeka?
Chin - Hong adati kuti m'mbiri yayikulu - Mayesero Olimbitsa Crust - 19
Kuphatikiza apo, anthu 37,000 adakumana ndi mayesero azachipatala a RSV, Chin - Hong adatinso.
Ofufuzawo adapeza zotsatirazi -- kuphatikiza maluma, kupweteka kwa mkono ndi kutupa kwa jakisoni -- Kwa Covid - 19 Mrna Katemera wa 19 anali ngati zachikhalidwe, omwe ali - RNNA ndipo anali ndi nthawi yochepa - mitengo yokwanira yoposa 90%.
Maphunziro owonjezera Chitetezo champhamvu chija chimakhala chogwirizana ndi chitetezo chanenedwa kuti katemera.
"Pali zosunga zonsezi zomwe zimagwiritsidwa ntchito kutsatira malipoti a anthu, osati kudziko lino lokha, zomwe adakumana nazo pogwiritsa ntchito katemera, komanso m'maiko ena," Chin - Hing adati. "Pakhala maphunziro angapo kuyambira 2020 kuwonetsa kuti palibe chomwe chimapangitsa kubereka, zinthu zonse zomwe anthu akhala nazo."
Hotezi anati palibe ukadaulo wa katemera ndi waluso, kuphatikiza ukadaulo wa MRNA, koma zili ndi zabwino monga phindu lopangidwira mwachangu mwachangu mwachangu, kuwalola kuti atumizidwe mwachangu.
Amatsutsana ndi lingaliro la FDA kuti achepetse Covid mtsogolo - akatemera 19 chifukwa covid ali ndi nthawi yayitali - Matenda a mtima ochulukirapo.
"Ndikuganiza kuti pali achichepere ambiri, kapena omwe ali ndi zaka 65, omwe akukhudzidwa ndi matenda a mtima wamtima kapena pansi." Adatero.
Nanga Bwanji Myocarditis?
Mafunso alumbira mozungulira momwe myocarditis amakhalira, omwe ndi kutupa kwa minofu ya mtima, kumachitika pambuyo pa Covird - Katemera 19.
Myocarditis imatha kuyambitsa arrhythmias, yomwe imakhala yofulumira kapena yovuta kwambiri. Zitha kupangitsanso minyewa ya mtima kufooka, chifukwa cha Cardiomomyapathy, zomwe zimakhudza kuthekera kwa mtima kum'patsa magazi moyenera.
Milandu ya myocarditis ndi pericarditis -- kutupa kwa sac yomwe ili ndi mtima -- zawonedwa kawirikawiri katemera wa kovid, malinga ndi Malo ogwiritsira ntchito matenda ndi kupewa.
Popeza sakanachitika, kwakhala pakati pa amuna achichepere, nthawi zambiri pakati pa zaka 18 ndi 29, patangotha masiku 7 atalandira kasitomala wachiwiri wa Mrna Covid, bungwe linalo likunena.
FDA, pofunsa makampani a katemera kuti achulukitse zolemba zawo, zomwe zatchulidwazi "-- deta kuchokera kumodzi mwa dongosolo la chitetezo cha bungwe la bungwe la bungwe ndi Phunziro lofalitsidwa mu Okutobala Izi zikutsatira anthu omwe adapanga myocarditis olumikizidwa ndi katemera wa Covid.
Chin - Hong adati chiwopsezo cha myocarditis ndichokwera kwambiri pambuyo pa Covid - 19 poyerekeza ndi katemera, ndipo kuti kukonzekera kuphikako kumakhala kopambana.
"Chiwopsezo cha Covid ndiwokwera kwambiri. Ngati mungayang'ane, 22 mpaka 31 milandu 29 miliyoni," adatero. "Panthawi yomwe Katemera awa amagwiritsidwa ntchito kwambiri pagululo, [chiopsezo cha myocarditis] ndi 1,500 miliyoni. Chifukwa chake, mukulankhula za 22 mpaka 31 mphindi."
