Maxay ka dhigan tahay waxtarka tallaalka corona?

Waxtarka tallaalka COVID-19 ee Pfizer waa 95%, Moderna waa 94%, Johnson & Johnson waa 66%, laakiin maxay dhab ahaantii boqolleydan ka dhigan yihiin?

Sida laga soo xigtay LiveScience, maaha kaliya su'aal cilmiyeed, sida loo fahmay maaha khabiiro Tirooyinkani waxay si weyn u saameeyaan aragtidooda iyo go'aanadooda ku saabsan qaadashada tallaalka, iyo xadka ay ka go'an tahay tallaabooyinka taxaddarka ah ee tallaalka ka dib, iyo saameynta fahamkan ayaa ka muuqda kor u qaadida hababka looga hortagayo faafitaanka cudurka si baaxad weyn.

Isaga oo tixraacaya tallaalka Pfizer, Professor Brian Parker, oo ku takhasusay fayrasyada kana tirsan Jaamacadda Drew ee New Jersey, ayaa muujisay aaminsanaanta in "ay muhiim tahay in la fahmo in uu yahay tallaal aad waxtar u leh. Iyo in waxtarkeedu aad uga badan yahay sida ay dadka qaar u malayn karaan, "iyaga oo xusay in aaminsanaanta in waxtarka 95% ay ka dhigan tahay in inta lagu jiro tijaabooyinka caafimaad ee ay samaysay Pfizer, 5% kuwa qaatay tallaalka ay la kulmeen cudurka Covid-19, waa ismaandhaaf guud.

Macnaha saxda ah ayaa ah in boqolkiiba dhabta ah ee dadka, tijaabooyinka Pfizer ama Moderna, uu ku dhacay COVID-19 ay yihiin 0.04%, taas oo qiyaastii boqol jeer ka yar fikradda khaldan. 95% waxa ay dhab ahaantii ka dhigan tahay in dadka la tallaalay ay 95% ka yaraayeen halista in uu ku dhaco COVID-19 marka loo eego kooxda kantaroolka, taas oo ah, dadka aan lagu tallaalin tijaabooyinka caafimaad. Si kale haddii loo dhigo, natiijooyinka tijaabooyinka caafimaad ee tallaalka Pfizer waxay muujiyeen in kuwa qaatay tallaalka ay 20 jeer ka yar yihiin inay qaadaan caabuqa marka loo eego kooxda xakamaynta.

Sida kor loogu qaado waxtarka tallaalka Corona

Ka fiican tallaalka jadeecada iyo hargabka

Professor Parker waxa uu intaa ku daray in caddayntan ay muujinayso in tallaalku, marka loo eego natiijooyinka tijaabooyinka caafimaad, uu yahay "mid ka mid ah tallaallada ugu waxtarka badan." Marka la barbardhigo, tallaalka MMR ee laba-qiyaasta ah ayaa 97% waxtar u leh jadeecada iyo 88% waxtar u leh qaamo-qashiirta, marka loo eego xogta CDC. Tallaalka ifilada xilliyeedku waxa uu u dhexeeyaa 40% iyo 60% wax ku ool ah (waxtarku wuu kala duwan yahay sannadba sanadka ka dambeeya, iyadoo ku xidhan tallaalka sanadkaas iyo noocyada hargabka), laakiin wuxuu weli ka hortagayaa, tusaale ahaan, qiyaastii 7.5 milyan oo xaaladood oo hargab ah oo gudaha Mareykanka ah. Maraykanka inta lagu guda jiro xilliga hargabka 2019-2020, sida uu qabo CDC.

Markaa, haddii waxtarku ka dhigan yahay in la dhimo kiisaska COVID-19 boqolkiiba dhawr, waxa kale oo mudan in la xuso qeexida waxa loo qaadan karo “kiis caabuqa COVID-19, sida Pfizer iyo Moderna labaduba u qeexaan kiis muujin kara ugu yaraan hal calaamad." Johnson & Johnson waxay ku qeexeen "kiis" natiijada smear PCR oo togan, oo lagu daray ugu yaraan hal calaamad dhexdhexaad ah (sida neefta oo gaaban, heerarka ogsijiinta dhiigga ee aan caadiga ahayn, ama heerka neefsiga oo aan caadi ahayn) ama laba calaamadood oo fudud. , daal, madax xanuun, lallabbo).

Dhibaatada isbarbardhigga

Qofka qaba kiis fudud oo ah COVID-19, marka loo eego qeexitaankan, wax yar ayuu saamayn karaa ama sariirta ayuu joogi karaa oo wuu bukoon karaa dhawr toddobaad.

Halkan dhibaato kale ayaa ka dhalata marka la is barbar dhigo waxtarka tallaallada midba midka kale, sida Professor Parker uu sharraxay inay adag tahay in la barbardhigo waxtarka tooska ah ee u dhexeeya tallaallada Pfizer, Moderna iyo Johnson & Johnson, si aan u magacaabo dhowr, sababtoo ah tijaabooyinka bukaan-socodka ayaa ka dhacay meelo kala duwan oo juquraafi ah. aagagga ay ku nool yihiin kooxo kala duwan, iyo waqtiyo kala duwan oo waqtiyo kala duwan lagu jiro xilliga masiibada waxay sidoo kale ka dhigan tahay inay jiraan isbeddello kala duwan wakhtiga tijaabada kasta.

"Waxaa jiray dad badan oo uu ku dhacay B117 [isbeddelka ku wareegaya Boqortooyada Midowday] ama noocyo kale oo noocyo ah iyo isbeddello intii lagu jiray tijaabada Johnson & Johnson marka loo eego intii lagu jiray tijaabada Moderna," Professor Parker ayaa raaciyay.

Ilaalinta calaamadaha

Saddexda tijaabo ee tallaal midkoodna waligii ma tijaabin bukaannada COVID-19 asymptomatic. Professor Parker wuxuu yiri: "Dhammaan tirooyinka waxtarka leh waxay muujinayaan ka-hortagga bilawga calaamadaha, maaha ka-hortagga caabuqa." (Daraasadaha hore qaarkood waxay soo jeedinayaan in tallaalada Pfizer iyo Moderna ay sidoo kale hoos u dhigaan tirada qaybaha fayraska ee jirka qofka, loo yaqaan 'viral load', iyo suurtagalnimada in weligood la tijaabiyo si togan, hoos u dhigista gudbinta.) Laakiin weli waxaa jirta baahi loo qabo in la xaqiijiyo saxnaanta Sida laga soo xigtay Professor Parker, kuwa lagu duray tallaalka kama tagi karaan xirashada maaskaro ilaalin ah oo raacaan inta kale ee tallaabooyinka taxaddarka ah.

Laakiin dhammaan seddexda tijaabo waxay sidoo kale adeegsadeen qeexitaan labaad oo ah 'kiisas caabuqa', kaasoo laga yaabo inuu aad uga muhiimsan yahay, maadaama heerka ugu muhiimsan uu yahay waxtarka iyo ka hortagga dhibaatooyinka ugu xun ee COVID-19. Markaa, saddexda shirkadood waxay sidoo kale cabbireen waxqabadka tallaalkooda xaalado daran, taasoo la macno ah wadnaha ama heerka neefsiga oo daran iyo/ama u baahan ogsijiin dheeri ah, gelitaanka ICU, neefsashada oo xumaata ama dhimasho.

100% ilaalinta dhimashada

Saddexda tallaalba waxay 100% waxtar u ahaayeen ka hortagga cudurrada daran lix toddobaad kaddib markii la qaatay qiyaasta koowaad (Moderna) ama toddoba toddobaad kaddib markii la tallaalay (Pfizer iyo Johnson & Johnson, maaddaama kan dambe uu ka kooban yahay hal dose oo keliya) Midna dadka lama tallaalin. In isbitaalka la seexiyo, mana jirin wax dhimasho ah oo ka dhashay Covid-19 oo la diiwaan geliyay, ka dib markii tallaalku noqday mid si buuxda waxtar u leh. "Aad ayaan ugu nasiib badannahay sida ay waxtar u leeyihiin tallaalladan," Professor Parker ayaa hadalkiisa ku soo gabagabeeyey.
