Contrarre il Covid-19 \u00e8 meglio della vaccinazione? Questa \u00e8 una delle domande pi\u00f9 urgenti che circola dall\u2019inizio della pandemia. Un team di ricercatori ha finalmente cercato di trovare risposte a questa domanda. <\/p>\n

In un nuovo studio<\/a> pubblicato su The Lancet, gli scienziati hanno condotto una revisione sistematica e una meta-analisi per scoprire quanta protezione offre una passata infezione da SARS-CoV-2 contro la reinfezione. <\/p>\n

\u201cComprendere il livello e le caratteristiche di protezione dall\u2019infezione passata da SARS-CoV-2 contro la successiva reinfezione, la malattia sintomatica COVID-19 e la malattia grave \u00e8 essenziale per prevedere il potenziale carico futuro della malattia, per progettare politiche che limitino i viaggi o l\u2019accesso alle sedi dove esiste un alto rischio di trasmissione e per orientare le scelte su quando ricevere le dosi di vaccino\u201d, ha scritto il team. <\/p>\n

Hanno sintetizzato sistematicamente diversi studi su COVID-19 per stimare la protezione dalle infezioni passate in base alla variante e al tempo trascorso dalla prima infezione. In questo modo, possono determinare se l\u2019immunit\u00e0 naturale pu\u00f2 fornire protezione da future infezioni.<\/p>\n

<\/div>\n

Gli scienziati hanno analizzato l'efficacia dell'infezione precedente in base all'esito contro la reinfezione, l'infezione sintomatica e la malattia grave o fatale. Vengono presi in considerazione anche la variante e il periodo trascorso dall'infezione originaria. <\/p>\n

Dopo aver raccolto e analizzato i dati di 65 studi provenienti da 19 paesi diversi, il team ha scoperto che una precedente infezione forniva protezione contro la malattia sintomatica del ceppo originale, le varianti alfa, beta e delta preoccupanti. La protezione contro le suddette varianti \u00e8 diminuita nel tempo ma \u00e8 rimasta a 78.6%.<\/p>\n

Ma per la variante omicron pi\u00f9 allarmante, l\u2019efficacia complessiva offerta da un\u2019infezione passata era solo di 45,3%. Anche la protezione dalla reinfezione da parte delle sottovarianti omicron era significativamente inferiore. Tuttavia, la protezione media contro la malattia grave derivante da tutte le varianti studiate era superiore a 78%. <\/p>\n

Il team ha concluso che, sulla base di dati scientifici, l\u2019immunit\u00e0 sviluppata attraverso una precedente infezione era molto efficace contro la reinfezione e la malattia grave di tutte le varianti prima dell\u2019omicron. <\/p>\n

I risultati suggeriscono che anche l\u2019immunit\u00e0 derivante da un\u2019infezione passata dovrebbe essere valutata insieme alla protezione fornita dai vaccini quando si prevede il futuro carico di malattia di COVID-19. Potrebbero anche aiutare a guidare gli esperti nel discernere le raccomandazioni sulle vaccinazioni, come previsto Contagio in diretta<\/a>.
