In the US, the Delta variant was first detected by mid-March 2021, and rapidly led to a new wave of infections. A nationwide study in the US reported a drop in Alpha variant cases from 70% in late April to 42% in mid-June, with the B.1.617.2 variant driving the shift [12]. In the early summer of 2021, Delta became the predominant variant in North America, as well as in South Africa, India, the UK and Canada [11,12,13,14,15]

美国大众普遍打疫苗是2021夏季的事情。那时候德尔塔早就扩散开了。几年前的事情都记不清楚？
