The researchers used studies from Chile and Britain to calculate the “baseline efficacy” of current vaccines -CoronaVac in the case of Chile and the Pfizer and Oxford/AstraZeneca shots in Britain. But even with a global vaccination rate of 95%, if population mobility was restored to 2019 levels, the researchers estimated that all COVID-zero regions would see more than 234 million infections within a year, including 64 million symptomatic cases and 2 million deaths.
They said it was more important for new vaccines to be effective against infection than against symptomatic disease or death.
