\nDatele provin din cercet\u0103ri nepublicate \u00eenc\u0103, dar din laboratoare excelente, examinate de c\u00e2\u0163iva oameni de \u015ftiin\u0163\u0103, scrie Corriere della Sera.<\/p>\n
\nProfesorul Alessandro Sette, directorul departamentului de cercetare a vaccinurilor din Institutul de Imunologie La Jolla (Ljl) San Diego, este unul dintre semnatari.<\/p>\n
\nAstfel, dr. Sette \u015fi colegii s\u0103i au ales 185 de b\u0103rba\u0163i \u015fi femei cu v\u00e2rste cuprinse \u00eentre 19 \u015fi 81 de ani, care s-au vindecat de Covid-19. Majoritatea avusese simptome u\u015foare, f\u0103r\u0103 spitalizare. Echipa a monitorizat patru componente ale sistemului imunitar: anticorpi, celule B \u015fi dou\u0103 tipuri de celule T, pentru a construi o imagine c\u00e2t mai complet\u0103 asupra imunit\u0103\u0163ii.<\/p>\n
\nConform concluziilor, la opt luni de la infectare, majoritatea celor vindeca\u0163i (peste 90%) are \u00eenc\u0103 suficiente celule imune pentru a evita infec\u0163ia \u015fi pentru a preveni boala Covid-19.<\/p>\n
\nPu\u0163ine persoane infectate nu au prezentat imunitate de lung\u0103 durat\u0103 dup\u0103 recuperare, posibil din cauza cantit\u0103\u0163ii de \u00eenc\u0103rc\u0103tur\u0103 viral\u0103 la care au fost expuse.<\/p>\n
\n\u201eAceast\u0103 cantitate de memorie ar \u00eempiedica probabil marea majoritate a oamenilor s\u0103 se \u00eemboln\u0103veasc\u0103 timp de mul\u0163i ani\u201d, a spus Shane Crotty, virolog la Institutul de Imunologie La Jolla, care a condus noul studiu.<\/p>\n
\nPotrivit echipei de savan\u0163i americani, persoanele vindecate ar putea fi protejate cel pu\u0163in opt luni, \u00eens\u0103 e posibil s\u0103 evite infec\u0163ia c\u00e2\u0163iva ani.<\/p>\n
\nDurata exact\u0103 a imunit\u0103\u0163ii este greu de prezis, deoarece oamenii de \u015ftiin\u0163\u0103 nu \u015ftiu \u00eenc\u0103 ce niveluri ale diferitelor celule imune sunt necesare pentru a protec\u0163ie, dar studiile de p\u00e2n\u0103 acum au sugerat c\u0103 ar putea fi suficient chiar \u015fi un num\u0103r mic de anticorpi sau celule T \u015fi B.<\/p>\n
\nDac\u0103 rezultatele cercet\u0103rii ar fi confirmate, ar reprezenta o veste excelent\u0103, deoarece cea mai mare \u00eengrijorare a fost c\u0103 imunitatea la coronavirus ar putea dura doar c\u00e2teva luni.<\/p>\n","protected":false},"excerpt":{"rendered":"
