Amashothi e-Covid aklanyelwe ukuvikela okuhlukile kwe-omicron aqala ukusabela okubuthakathaka kokuzivikela komzimba ngokumelene ne-subvariant evela ngokushesha ye-BQ.1.1 kunohlobo olunamandla ngaphambili, ngokocwaningo olusha lwelebhu.
Ososayensi eNyuvesi yaseTexas Medical Branch, iUcwaningo olushicilelwe ku-inthanethi ngoLwesibili ku-Nature Medicineithole ukuthi amashothi e-booster asebenze kahle ngokumelene ne-BA.5 subvariant abeklanyelwe ukukhomba.
Kodwa ama-booster awazange aqalise impendulo eqinile lapho ebhekene ne-BQ.1.1, ososayensi bathola. Amasosha omzimba ayephansi ngokuphindwe kane uma kuqhathaniswa ne-BQ.1.1 uma kuqhathaniswa ne-BA.5. Lawa ma-antibodies avimbela igciwane elibangela i-Covid-19 ukuthi lingangeni kumaseli abantu.
Abantu abanomlando wangaphambili wokutheleleka abathole i-omicron booster, nokho, babe nempendulo enamandla ku-BQ.1.1. Amasosha omzimba anciphisa i-BQ.1.1 ayecishe abe phezulu ngokuphindwe kane kuleli qembu uma kuqhathaniswa nabantu abangenawo umlando wokutheleleka ababhekane ne-subvariant, ososayensi bathola.
Cishe u-42% wabantu abadala e-US banomlando wangaphambili wokutheleleka, ngokocwaningo olushicilelwe yiCenters for Disease Control and Prevention ngesonto eledlule. Imiphumela yayisekelwe kumasampula egazi labantu abadala aqoqwe kusukela ngo-Agasti 2021 kuya kuMeyi 2022.
I-subvariant ye-Omicron BQ.1.1 ivela endleleni ukuze ibe okuhlukile okuvelele e-US Okwamanje yenza cishe u-32% wezifo e-US, ngokusho kwedatha yokubhekwa kwe-CDC. I-Omicron BA.5, ngakolunye uhlangothi, manje imele cishe u-14% wezifo ezintsha.
Ama-booster enze obuthaka kakhulu ngokumelene ne-subvariant ye-XBB.1, ososayensi bathola. Amasosha omzimba abe ngaphansi ngokuphindwe izikhathi eziyisishiyagalombili uma kuqhathaniswa ne-XBB.1 kune-omicron BA.5. Kodwa-ke, abantu abanomlando wangaphambili wokutheleleka abathola i-booster babenamasosha omzimba aphindwe kathathu ngokumelene ne-XBB.1 kunabantu abangenawo umlando we-Covid, ngokocwaningo.
UDkt. Anthony Fauci, umeluleki omkhulu wezokwelapha e-White House, uthe ngenyanga edlule ukuvikelwa okuhlinzekwa ama-booster kuyehla ngandlela-thile ku-BQ.1.1, kodwa kuncipha ngokuphindaphindiwe ku-XBB.
“Ngakho-ke, ungalindela ukuvikelwa okuthile, kodwa hhayi ukuvikelwa okufanele,” kusho uFauci etshela izintatheli esithangamini nabezindaba eWhite House ngaphambi kweholidi lokubonga.
Ucwaningo lwaseTexas luhlole amasampula egazi abantu abangu-29 abangenawo umlando wokutheleleka abathole i-omicron booster; amasampula angama-23 avela kubantu abathole i-booster ababenomlando wokutheleleka; kanye nabantu abangama-25 abathole umthamo wesine womgomo wokuqala.
Amasampula aqoqwa ezinsukwini eziyi-14 kuya kwezingama-32 ngemuva kwe-omicron booster kanye nezinsuku ezingama-23 kuye kwezingama-94 ngemuva komthamo wesine womgomo wokuqala.
