Kuthetha ukuthini ukusebenza kogonyo lwe-corona?

Ukusebenza kogonyo lwe-COVID-19 olusuka kwi-Pfizer ngama-95%, iModerna ngama-94%, kwaye uJohnson & Johnson ngama-66%, kodwa zithetha ukuthini ezi pesenti?

Ngokutsho kweLiveScience, ayingombuzo wemfundo kuphela, indlela eqondwa ngayo ayisiyiyo iingcali La manani achaphazela kakhulu iimbono zabo kunye nezigqibo malunga nokufumana isitofu sokugonya, kunye nobukhulu bokuzinikela kwabo kumanyathelo okukhusela emva kokugonywa, kunye nemiphumo yolu kuqonda ibonakaliswe ekuqiniseni iindlela zokuthintela ukusasazeka kwesi sifo kwinqanaba elikhulu.

Ebhekisa kwisitofu sokugonya i-Pfizer, uNjingalwazi uBrian Parker, ugqirha wentsholongwane egazini kwiYunivesithi yaseDrew eNew Jersey, wavakalisa inkolelo yakhe yokuba “kubalulekile ukuqonda ukuba sisitofu sokugonya esisebenza kakhulu. Kwaye ukuba ukusebenza kwayo kungaphezulu kunokuba abanye benokucinga, ”ephawula ukuba inkolelo yokuba ukusebenza kwama-95% kuthetha ukuba ngexesha lolingo lwezonyango olwenziwe nguPfizer, i-5% yabo bafumana isitofu sokugonya baye bachanabeka kwi-Covid-19 isifo. ukungaqondi okuqhelekileyo.

Intsingiselo echanekileyo yeyokuba elona pesenti yabantu abathi, kulingo lwePfizer okanye lweModerna, bosulelwa yi-COVID-19 yi-0.04%, emalunga nekhulu eliphindwe kalikhulu kunolo mbono uphosakeleyo. Eyona nto ithethwa ngama-95% kukuba abantu abagonyiweyo babenomngcipheko osezantsi wama-95% wokosulelwa yi-COVID-19 kuneqela lolawulo, okuthetha ukuba abantu abangakhange bagonywe kulingo lwezonyango. Ngamanye amazwi, iziphumo zolingo lwezonyango lwesitofu sokugonya se-Pfizer zibonise ukuba abo bafumana isitofu sokugonya babenokuphinda-phinda ngama-20 amathuba okuba baphuhle usulelo kuneqela lolawulo.

Ukonyusa njani ukusebenza kogonyo lweCorona

Ingcono kunemasisi kunye nesitofu sokugonya somkhuhlane

Unjingalwazi uParker wongeze ukuba le ngcaciso ibonisa ukuba isitofu sokugonya, ngokweziphumo zovavanyo lweklinikhi, "lelinye lawona mayeza asebenzayo." Xa kuthelekiswa, isitofu sokugonya se-MMR seedosi ezimbini sisebenza ngama-97% kwimasisi kunye ne-88% esebenzayo ngokuchasene noqwilikana, ngokwedatha yeCDC. Ugonyo lomkhuhlane wonyaka lukwaphakathi kwe-40% kunye ne-60% esebenzayo (ukusebenza kuyahluka unyaka nonyaka, kuxhomekeke kwisitofu salo nyaka kunye nohlobo lomkhuhlane), kodwa lusathintela, umzekelo, kuqikelelwa ukuba zizigidi ezisi-7.5 iimeko zomkhuhlane eUnited States. eUnited States ngexesha lomkhuhlane ka-2019-2020, ngokweCDC.

Ke, ukuba ukusebenza kuthetha ukunciphisa iimeko ze-COVID-19 ngepesenti encinci, kufanelekile ukuba uqaphele inkcazo yento enokuthi ithathwe njenge "ityala le-COVID-19, njengoko zombini uPfizer kunye neModerna beyichaza njengetyala elingabonisa ubuncinci. uphawu olunye.” (Nokuba ithambile kangakanani) iziphumo zovavanyo lwe-PCR. UJohnson & Johnson bachaza 'imeko' njengesiphumo se-PCR se-smear esiqinisekileyo, kunye nobuncinci uphawu olunye oluphakathi (njengokuphefumla kancinci, amaqondo angaqhelekanga eoksijini egazini, okanye umlinganiselo wokuphefumla ongaqhelekanga) okanye iimpawu ezimbini ezingembi kakhulu. , ukudinwa, intloko ebuhlungu, isicaphucaphu).

Ingxaki yokuthelekisa

Umntu onemeko ebuthathaka ye-COVID-19, ngokwale nkcazo, unokuchaphazeleka kancinci okanye ahlale ebhedini kwaye agule iiveki ezimbalwa.

Apha kuvela enye ingxaki ngokuthelekisa ukusebenza kwezitofu zokugonya enye kwenye, njengoko uNjingalwazi uParker echaza ukuba kunzima ukuthelekisa ukusebenza ngokuthe ngqo phakathi kwezitofu zokugonya iPfizer, iModerna kunye neJohnson & Johnson, ukukhankanya ezimbalwa, kuba ulingo lwezonyango lwenzeka kwiindawo ezahlukeneyo zejografi. iindawo ezinamaqela ahlukeneyo abantu, kwaye ngamaxesha ahlukeneyo kancinane kwixesha lobhubhane athetha ukuba kukho utshintsho olwahlukileyo ngexesha lolingo ngalunye.

Unjingalwazi uParker wongeze wathi, "Bekukho abantu abaninzi abosulelwe yi-B117 [utshintsho olujikelezayo e-UK] okanye ezinye iintlobo zoxinzelelo kunye notshintsho ngexesha lovavanyo lukaJohnson & Johnson kunangexesha lolingo lweModerna."

Ukukhuselwa kweempawu

Kwaye akukho nalinye kulingo lokugonya oluthathu olwakhe lwavavanya izigulana ezine-asymptomatic COVID-19. Unjingalwazi uParker uthe: "Onke amanani asebenzayo abonisa ukhuseleko ekuqalekeni kweempawu, hayi ukukhuselwa kusulelo." (Olunye uphononongo lwangaphambili lucebisa ukuba izitofu zokugonya iPfizer kunye neModerna zikwanciphisa inani lamasuntswana entsholongwane egazini emzimbeni womntu, abizwa ngokuba ngumthamo wentsholongwane egazini, kunye namathuba okuze avavanywe ukuba unayo, ukunciphisa usulelo.) Kodwa kusekho imfuneko yokuqinisekisa ukuchaneka NgokukaNjingalwazi Parker, abo batofelwe ngesitofu sokugonya abanakuyeka ukunxiba iimaski zokhuselo kwaye balandele amanye amanyathelo okhuseleko.

Kodwa omathathu amalingo aphinde asebenzisa inkcazo yesibini 'yemeko yosulelo', enokuthi ibaluleke ngakumbi, njengoko eyona nqobo ithatha isigqibo kukusebenza kunye nokhuseleko kwezona ngxaki zimbi ze-COVID-19. Ke, ezi nkampani zintathu zikwalinganise ukusebenza kogonyo lwazo kwiimeko ezimandundu, okuthetha ukuba intliziyo ebukhali okanye izinga lokuphefumla elichaphazelekileyo kunye/okanye imfuno yeoksijini eyongezelelweyo, ukwamkelwa kwe-ICU, ukusilela kokuphefumla okanye ukufa.

100% ukhuseleko lokufa

Zontathu izitofu zisebenze nge-100% ekuthinteleni isifo esiqatha kwiiveki ezintandathu emva kwedosi yokuqala (i-Moderna) okanye iiveki ezisixhenxe emva kwedosi yokuqala (yePfizer noJohnson & Johnson, ekubeni le yokugqibela iqulethe idosi enye kuphela) Akukho namnye ebantwini owagonywayo. ukuze bamkelwe esibhedlele, kwaye akukho kufa kwabantu ngenxa ye-COVID-19 kwarekhodwa, emva kokuba ugonyo lusebenze ngokupheleleyo. “Sinethamsanqa elikhulu ngendlela ezisebenza ngayo ezi zitofu,” uvale ngelo uNjingalwazi uParker.
