Matenda opambana komanso owonjezera

Nkhani yabwino ndiyakuti mlingo wathunthu wa katemera wovomerezeka wa COVID-19 udakali wothandiza. "Matemera onse amagwira ntchito bwino," atero a Jeff Kwong, katswiri wa matenda opatsirana ku Yunivesite ya Toronto. "Ndipo katemerayu anali woteteza kwambiri ku zotsatira zoyipa poyerekeza ndi matenda," Kwong awonetsa mu kafukufuku, yemwe sanawunikenso ndi anzawo, mphamvu ya katemera wa Pfizer, Moderna, ndi AstraZeneca polimbana ndi matenda, kugona m'chipatala, kapena imfa pakati pa Disembala 2020 ndi Meyi 2021.

Kafukufuku wambiri wasonyeza kuti katemera wa Moderna ndi Pfizer amatetezabe ku Delta, ngakhale osati komanso motsutsana ndi mitundu yakale. Anthu omwe alibe katemera amapanga oposa 90 peresenti ya milandu yatsopano yomwe yatsimikiziridwa pakati pa mayiko omwe amatsata deta komanso momwe aliri katemera.

"[Katemera] amachepetsa chiopsezo chokhala ndi vuto lalikulu monga kugonekedwa m'chipatala," akutero Aziz Sheikh, katswiri wazachipatala ku The University of Edinburgh, Scotland, UK yemwe adawonetsa kuti Delta idapangitsa kuti anthu ambiri azigonekedwa m'chipatala kuposa mtundu wa Alpha, womwe udayambitsa matenda oopsa kuposa omwe adayambitsa SARS-CoV-2. "Ponseponse, akugwira ntchito." Zidole za Silicone Zogonana

CDC ikuyerekeza kuti katemera wa COVID-19 amachepetsa chiwopsezo cha matenda a SARS-CoV-2 kasanu ndi katatu komanso chiopsezo chodwala, kugonekedwa m'chipatala, kapena kufa ka 25.

Koma kuyesa kosakwanira m'dziko lonse lapansi kumapangitsa kuti zikhale zosatheka kudziwa momwe Delta imafalikira ndi mitundu ina. Pakakhala kufalikira kwakukulu kwa Delta m'derali, ngakhale anthu omwe ali ndi katemera wathunthu amakhala pachiwopsezo chotchedwa "katemera woyambitsa matenda," omwe CDC imatanthauzira ngati ma genetic kapena mapuloteni ochokera ku SARS-CoV-2 amapezeka mumphuno patatha masiku 14 munthu atalandira mlingo wovomerezeka wa katemera wovomerezeka ndi FDA.

Mlingo iwiri ya katemera wa AstraZeneca ndi Pfizer akuti ndi 60 ndi 88 peresenti yogwira ntchito, motsatana, motsutsana ndi matenda oyambitsidwa ndi Delta. Makatemera ambiri omwe amaperekedwa ku US (Moderna ndi Pfizer) amafunikira kuwombera kawiri kuti atetezedwe kwambiri. Katemerawa sagwira ntchito kwambiri polimbana ndi Delta pambuyo pa jab imodzi yokha, akutero Olivier Schwartz, wamkulu wa Virus and Immunity Unit ku Institut Pasteur, Paris, yemwe adatsogolera kafukufuku yemwe adawonetsa kuti mlingo umodzi wa katemera wa AstraZeneca ndi Pfizer kapena matenda am'mbuyomu saletsa kusiyana kwa Delta.

Chifukwa cha kuchuluka kwa kuchepa kwa mphamvu zolimbana ndi mitundu yatsopano monga Delta, Pfizer ikufuna kuvomerezedwa ndi mlingo wowonjezera wa katemera wake. Moderna akuyesanso mlingo wosinthidwa wa katemera wa mRNA. US Food and Drug Administration (FDA) ikuyembekezeka kumaliza dongosolo la katemera wa COVID-19 posachedwa.
