Mishonga inodzivirira zvirwere kwemakore akawanda here?

Tichifunga nezvemafungu ekuchinja kwecorona kutenderera pasirese uye kuwedzera kwehuwandu hwehutachiona, ongororo ichangobva kuitika yakaratidza kuti majekiseni maviri ePfizer nemumwe wake "Bionic", kuwedzera kuModerna, anogona kupa dziviriro kubva kuhutachiona hweCorona kwemakore. kana kunyange kwoupenyu hwose.

Ongororo yeUS yakawana kuti vanhu vazhinji vakabayiwa nhomba yeMRNA vanogona kunge vasingade mamwe madosi ekuwedzera, chero hutachiona uye hutsva hwahwo husina kushanduka zvakanyanya.

"Chiratidzo chakanaka chekuchengetedzwa kwekudzivirira kwedu kwekudzivirira nejekiseni," akadaro Ali Al-Yaidi, mutariri wechidzidzo uye mubatsiri purofesa paWashington University muSt. Louis, maererano nezvakataurwa ne "New York Times."

Maseru ekudzivirira zvirwere ndiwo akavanzika

Chiremba nevamwe vake muchidzidzo ichi vakawana kuti masero edziviriro anoona hutachiona anoramba ari mumiviri yevanhu vakapora kubva kukorona kwemwedzi ingangoita misere mushure mekutapukirwa.

Zvakare, ongororo yakaitwa neimwe timu yakaratidza kuti masero anonzi "memory B" anoramba achikura uye achisimba kwerinenge gore mushure mekutapukirwa.

Muchidzidzo chitsva ichi, masayendisiti akakurudzira kuti kusadzivirirwa kwaizogara kwemakore, uye pamwe kwehupenyu, muvanhu vakatapukirwa nehutachiona uye vakabaiwa gare gare, asi hazvina kujeka kwavari kana kubaya kwega kungave nemhedzisiro yenguva refu. zvakafanana nevaya vaiva nechirwere kare.

Saka, timu yakatarisa kunobva masero endangariro, malymph nodes, uko aya masero ekudzivirira anodzidziswa kuziva uye kurwisa hutachiona.

Vakaona kuti mushure mekutapukirwa kana kubaiwa, chiumbwa chinonzi germinal centre chinoumba mumalymph nodes. Iri muchimiro ichi umo masero anodzidzisa zvakasimba kurwisa utachiona.

Kana maseru aya achidzidzira kurebesa, ndipo paanowedzera mukana wekumisa hutachiwana hunogona kubuda.

B-cell kuvandudzwa inodzivirira kubva kuhutachiona

Zvimwechetezvo, Marion Pepper, chiremba wezvirwere zvezvirwere paUniversity yeWashington kuSeattle, akatsanangura kuti munhu wese anogara akatarisisa kushanduka kwehutachiona, achiona kuti ongororo iyi inoratidza kuti "immune B masero ari kubudawo, zvinoreva kuti kuenderera mberi uku kuchaita. kudzivirira utachiona.”

Muchidzidzo ichi, chikwata chakaongorora dhata revanhu makumi mana nemumwe, kusanganisira vasere vaive nenhoroondo yekutapukirwa nehutachiona, uye vese vakabaiwa madosi maviri ejekiseni re "Pfizer", uye boka rakatora sampuli kubva mumalymph nodes e. 41 vanhu mushure metatu, ina, shanu, manomwe uye mavhiki gumi nemashanu mushure mekutanga dosi. .

Vatsvakurudzi vakaona kuti mavhiki gumi nemashanu mushure mekutanga kwejezi rekudzivirira, nzvimbo yehutachiona yakanga ichiri kushanda zvakanyanya muvatori vechikamu gumi nevana, uye kuti nhamba yendangariro "B" masero akaziva hutachiona haana kuderera.

Pamusoro pezvo, Al Yabidi akatsanangura kuti "kuenderera mberi kwemhinduro kweinenge mwedzi mina mushure mejekiseni chiratidzo chakanaka kwazvo," sezvo hutachiona hwehutachiona hunowanzosvika pakakwirira kwevhiki imwe kusvika mbiri mushure mekudzivirira uye dzobva dzapera.

Vakwegura uye vanhu vasina immunocompromised vanoda boosters

Nekuda kwake, Dipta Bhattacharya, chiremba wekudzivirira zvirwere paYunivhesiti yeArizona, akati nzvimbo dzeutachiona dzinokurudzirwa nemishonga yekudzivirira "mRNA" yakaramba ichishanda mwedzi mushure mekunge zvaitika.

Akasimbisa kuti kukosha kwechidzidzo ichi kuri pakuti zvizhinji zvinozivikanwa nevesainzi nezvekuenderera mberi kwekuvapo kwenzvimbo dzehutachiona zvinobva mukutsvagisa mhuka, uye chidzidzo ichi ndicho chekutanga pavanhu.

Mhedzisiro yacho inoratidza kuti ruzhinji rwevanhu vakabaiwa vachange vaine hutachiwana hwenguva refu kubva kumatambudziko aripo ekoronavirus.

Asi vanhu vakuru, vanhu vane immune system isina simba, uye avo vanotora mishonga inodzvanyirira immune system vangada zvinosimudzira.

Kana vari vanhu vakapora kubva kuhutachiona uye vakabaiwa, vanogona kusada zvachose, sezvo mazinga avo ekudzivirira anowedzera nekuti ndangariro "B" masero akange achikura pamberi pejekiseni.

Chidzidzo ichi chakaratidza kuti zvinonetsa kufanotaura nguva yekudzivirirwa kwekudzivirira muviri uchishandisa mRNA vaccine, asi kana pakashaikwa madhiri anogona kutiza kusadzivirirwa, zvinoita sekuti zvinokwanisika kuenderera kwehupenyu.

Mimwe misoro: 

Unoita sei nemudiwa wako mushure mekudzoka kubva mukurambana?
