Covid-19 in South America: Vaccine Rollout Led to Big Drop in Cases

South America, exceptionally hard-hit by Covid-19, is seeing a sudden drop in cases and deaths, apparently from rapid and thorough vaccines on the heels of a horrific wave that provided antibodies to those it didn’t kill. Over a seven-day period, the continent now makes up 6% of cases and 9% of deaths, the lowest since the start of the pandemic. At its peak in June, it represented 38% of global infections and 44% of fatalities. One peculiarity of the continent is that the delta variant upending plans from Asia to the U.S. hasn’t found traction there.
