Salvi grazie al vaccino. L'arrivo dei preparati contro il Covid-19 ha consentito di salvare quasi 20 milioni di persone nel mondo solo nel primo anno di campagna vaccinale (dicembre 2020-dicembre 2021). Lo mostrano le stime realizzate da un gruppo di ricercatori guidati dall'Imperial College London di Londra e pubblicate su The Lancet Infectious Diseases.
La gestione della pandemia

Lo studio, basato sui dati di 185 Paesi, evidenzia come le differenze di accesso ai farmaci abbiano penalizzato i Paesi poveri e come si sarebbero potuti evitare altri 599'300 decessi (il 59,7% dei quali nei paesi a medio/basso reddito) se si fosse raggiunto l'obiettivo dell'Organizzazione mondiale della sanità (OMS) di vaccinare il 40% della popolazione in ogni paese entro la fine del 2021.
Secondo lo studio, il 79% dei decessi (15,5 milioni dei 19,8 milioni totali) è stato evitato grazie alla protezione diretta fornita dai vaccini contro le forme gravi di Covid, mentre la restante quota di decessi è stata prevenuta grazie alla protezione indiretta, cioè alla ridotta trasmissione del virus nella popolazione e al minore peso del Covid sui sistemi sanitari, che ha migliorato l'accesso alle cure mediche per chi ne aveva più bisogno.
Nel mondo il numero dei decessi ad oggi, secondo i dati della Johns Hopkins University, è di 6,32 milioni.
