Pejana lehlabuleng lena, ho ile ha utloahala eka seoa sa COVID-19 se fetohile sekhutlo. Batho ba entoeng ka botlalo ba ile ba bolelloa ke Litsi tsa Taolo le Thibelo ea Mafu ka Mots'eanong hore ha ba sa hlola ba roala limaske maemong a mangata, mme palo ea linyeoe tsa COVID-19 tsa US le eona e fokotsehile ka nako e itseng. Empa joale, mofuta oa Delta (B.1.617.2) o ile oa qala ho hlahisa hlooho ea eona e mpe.

Phapang ea Delta e ikarabella bakeng sa liperesente tse 82 tsa linyeoe tse ncha tsa COVID-19 ho la US ho tloha ka la 17 Phupu, ho latela data e tsoang ho CDC. E boetse e hokahantsoe le kotsi e kholo ea 85 ea ho kena sepetlele ho feta likhoele tse ling, 'me e fetisoa ka liperesente tse 60 ho feta mofuta oa Alpha (B.1.17), mofuta o neng o le matla pele, ho latela phuputso ea Phuptjane 2021. (E amanang: Hobaneng ha Phapang e ncha ea Delta COVID e tšoaetsana hakaale?)

Liphuputso tsa morao-rao tse tsoang England le Scotland li fana ka maikutlo a hore vaksine ea Pfizer ha e sebetse ho sireletsa khahlanong le phapano ea Delta joalo ka Alpha, ho latela CDC. Hona joale, seo ha se bolele hore ente e ke ke ea u thusa ho felisa lefu la matšoao ho tsoa khatello - e mpa e bolela feela hore ha e sebetse hantle ha e bapisoa le bokhoni ba eona ba ho loants'a Alpha. Empa litaba tse ling tse ka bang monate: Ka Laboraro, Pfizer e phatlalalitse hore tekanyetso ea boraro ea ente ea eona ea COVID-19 e ka eketsa ts'ireletso khahlano le mofuta oa Delta, ho feta moo ho litekanyetso tsa eona tse peli tsa hajoale.

Lintlha tse rometsoeng marang-rang ho tsoa Pfizer li fana ka maikutlo a hore tekanyetso ea boraro ea ente e ka fana ka makhetlo a fetang a mahlano litekanyetso tsa lesole la mmele khahlano le phapano ea Delta ho batho ba lipakeng tsa 18 le 55 ha e bapisoa le ea lithunya tse peli tse tloaelehileng. Mme, ho ea ka liphuputso tsa k'hamphani, booster e ne e sebetsa le ho feta ho batho ba lilemo li 65 ho isa ho tse 85, e eketsa litekanyetso tsa antibody tse ka bang makhetlo a 11 har'a sehlopha sena. Sohle se boleloang, sete ea data e ne e le nyane - ke batho ba 23 feela ba neng ba ameha - mme liphuputso ha li so hlahlojoe ke lithaka kapa li phatlalalitsoe koranteng ea bongaka.

"Re ntse re lumela hore ho kanna ha hlokahala mochini oa booster oa boraro nakong ea likhoeli tse tšeletseng ho isa ho tse 12 kamora ho entoa ka botlalo ho boloka maemo a phahameng a ts'ireletso, mme lithuto li ntse li tsoela pele ho lekola polokeho le boits'ireletso ba tekanyetso ea boraro," ho boletse Mikael Dolsten, MD, Ph.D., ofisiri e ka sehloohong ea mahlale le mopresidente oa Patlisiso ea Lefatše ka Bophara, Nts'etsopele, le Medicalfor Pfizer, polelong ka Laboraro. Dr. Dolsten o tsoetse pele ho re, "Lintlha tsena tsa pele li khothatsa haholo ha Delta e ntse e tsoela pele ho hasana."

Kamoo ho bonahalang kateng, ts'ireletso e fanoang ke ente e tloaelehileng ea litekanyetso tse peli ea Pfizer e ka qala ho "feela" likhoeli tse tšeletseng kamora ho entoa, ho latela tlhahiso ea senatla sa meriana ka Laboraro. Kahoo, tekanyetso ea boraro e ka bang molemo e ka ba molemo haholo ho, habonolo feela, ho ts'ehetsa ts'ireletso ea batho khahlano le COVID-19 ka kakaretso. Ho bohlokoa ho hlokomela, leha ho le joalo, hore li-antibody - leha e le karolo ea bohlokoa ea boits'ireletso - ha se eona feela metric ea ho metha bokhoni ba motho ba ho loants'a vaerase, ho latela The New York Times. Ka mantsoe a mang, ho hlokahala nako le lipatlisiso tse ngata ho utloisisa kannete hore na tekanyetso ea boraro ea Pfizer e fosahetse, ke sohle seo e leng sona.

Ntle le Pfizer, baetsi ba bang ba ente le bona ba tšehetse mohopolo oa ho thunngoa ha booster. Mothehi-mothehi oa Moderna, Derrick Rossi Litaba tsa CTV Mathoasong a Phupu hore ho thunngoa khafetsa ha ente ea COVID-19 "ka sebele" ho tla hlokahala ho boloka boits'ireletso khahlanong le vaerase. Rossie o bile a fihla a re, "Ho kanna ha se makatse hore ebe re hloka booster e thunngoang selemo se seng le se seng." (E amanang: U kanna oa hloka lethal dose ea boraro ea ente ea COVID-19)

Johnson & Johnson CEO Alex Gorsky le eena o ile a qhomela holim'a terene ea booster-in-the-future nakong Wall Street Journal 'Seboka sa Tech Health mathoasong a Phuptjane, a re tekanyetso e ekelitsoeng e kanna ea hlokahala bakeng sa ente ea k'hamphani ea hae - bonyane ho fihlela boits'ireletso ba mehlape (aka ha bongata ba batho bo sa tšoaroe ke lefu le tšoaetsanoang) bo fihletsoe. O ile a eketsa a re: "Re kanna ra sheba ho tšoaea hona hammoho le mafu a feberu, mohlomong lilemong tse 'maloa tse tlang."

Empa mathoasong a Phupu, CDC le Tsamaiso ea Lijo le Lithethefatsi li phatlalalitse polelo e kopaneng e reng "MaAmerika a entetsoeng ka botlalo ha a hloke ho thunngoa ka nako ena" le hore "FDA, CDC, le NIH [Mekhatlo ea Naha ea Bophelo ] ba tšoarehile ts'ebetsong e thehiloeng ho saense, e matla ea ho nahana hore na ho ka hlokahala kapa ha ho hlokahala matlafatso."

"Re ntse re tsoela pele ho hlahloba lintlha leha e le life tse ncha ha li ntse li fumaneha 'me re tla tsebisa sechaba," ho bala polelo eo "Re itokiselitse litekanyetso tsa booster haeba le ha saense e bontša hore lia hlokahala."

Ebile, ka Laboraro Dr. Dolsten o boletse hore Pfizer o "lipuisanong tse tsoelang pele" le mekhatlo ea taolo naheng ea U.S. mabapi le monyetla oa boraro oa booster oa ente ea hajoale. Haeba mekhatlo e nka qeto ea hore ho hlokahala, Pfizer e rera ho kenya kopo ea tumello ea ts'ebeliso ea tšohanyetso ka Phato, ho latela Dr. Dolstein. Ha e le hantle, o kanna oa fumana sethunya sa COVID-19 selemong se tlang.

Litaba tse paleng ena li nepahetse ho tloha nakong ea khatiso. Ha lintlafatso mabapi le coronavirus COVID-19 li ntse li tsoela pele ho fetoha, ho ka etsahala hore tlhahisoleseling le likhothaletso tse ling paleng ena li fetohile ho tloha ha e qala ho phatlalatsoa. Re u khothaletsa ho etela khafetsa ka lisebelisoa tse kang CDC, WHO, le lefapha la hau la bophelo bo botle ba sechaba bakeng sa lintlha le likhothaletso tsa morao-rao.
