Una variante altamente mutata del ceppo Omicron, denominata BA.2.86, ha sollevato preoccupazioni in tutto il mondo con l\u2019aumento dei casi negli Stati Uniti, nel Regno Unito, in Cina e in diverse parti d\u2019Europa. Gli esperti ora ritengono che la nuova variante, denominata anche Pirola, sia meno contagiosa e meno efficace dal punto di vista immunitario di quanto temuto.<\/p>\n

In due esperimenti di laboratorio separati condotti negli Stati Uniti, gli scienziati hanno testato come gli anticorpi di persone vaccinate e infette potrebbero essere in grado di difendere le attuali varianti di COVID-19, inclusa la variante BA.2.86.<\/p>\n

Hanno scoperto che il sistema immunitario delle persone recentemente infettate dalla sottovariante XBB forniva il pi\u00f9 alto livello di protezione contro una serie di varianti circolanti, tra cui BA.2.86. I risultati dei test hanno inoltre indicato che il vaccino aggiornato contro il COVID-19 mirato alla variante XBB.1.5 pu\u00f2 fornire una protezione aggiuntiva contro Pirola.<\/p>\n

"Due laboratori indipendenti hanno sostanzialmente dimostrato che BA.2.86 essenzialmente non rappresenta un'ulteriore fuga immunitaria rispetto alle varianti attuali", ha affermato il dottor Dan Barouch, direttore del Centro per la virologia e la ricerca sui vaccini presso il Beth Israel Deaconess Medical Center e leader di uno dei laboratori che hanno testato la variante, detto<\/a> CNN.<\/p>\n

\u201cOra abbiamo il 2\u00b0 laboratorio che riporta i dati di neutralizzazione su BA.2.86 E la notizia \u00e8 migliore di quanto mi aspettassi E mi rende pi\u00f9 incoraggiato dal fatto che il nuovo vaccino in arrivo avr\u00e0 un vantaggio reale anche contro l\u2019attuale variante dominante (EG.5) come BA.2.86", il dottor Ashish Jha, ex coordinatore della risposta al COVID-19 della Casa Bianca, twittato<\/a>.<\/p>\n

Pirola ha pi\u00f9 di 30 mutazioni nella sua proteina spike rispetto a XBB.1.5, che in precedenza era una variante dominante negli Stati Uniti. L'enorme numero di mutazioni in Pirola ha destato preoccupazione tra gli esperti.<\/p>\n

\u201cQuando siamo passati dalla [variante Omicron] XBB.1.5 alla [Eris] EG.5, si trattava forse di una o due mutazioni. Ma questi massicci spostamenti, che abbiamo visto anche da Delta a Omicron, sono preoccupanti\u201d, ha affermato Scott Roberts, specialista in malattie infettive di Yale Medicine. disse<\/a>.<\/p>\n

Tuttavia, secondo i rapporti, legati al COVID deceduti<\/a> sono diminuiti con la diffusione di Pirola e la variante \u00e8 circa 60% meno contagiosa dei virus XBB.1.5.<\/p>\n

La variante BA.2.86 si \u00e8 diffusa in almeno 11 paesi dopo essere stata identificata per la prima volta in Danimarca il 24 luglio. L'OMS e i Centri per il controllo e la prevenzione delle malattie (CDC) hanno aggiunto la variante alla loro lista di controllo.<\/p>\n

\u201cL\u2019attuale valutazione dei CDC \u00e8 che questo vaccino aggiornato sar\u00e0 efficace nel ridurre le malattie gravi e i ricoveri ospedalieri.
