Why are Covid cases so high when millions are fully vaccinated? Blame the delta variant, experts say

  • The number of Covid cases being recorded daily in the West remains high, and even resembles earlier peaks at different points, or Covid waves, during the pandemic.
  • The high numbers of cases remains attributable to the spread of the highly infectious delta variant, which usurped previous variants that themselves were more infectious than the original strain of Covid-19.

LONDON — Looking at the Covid case data in the U.S., U.K. and the rest of Europe, you'd be forgiven for thinking that, despite 18 months of a global health crisis and advanced vaccination rollouts, we're in just as bad a situation as we ever were.

Certainly the number of Covid cases being recorded daily in the West remains high, and even resembles earlier peaks at different points, or Covid waves, during the pandemic.

The current 7-day moving average of daily new cases stands at 153,246, an increase of 4.9% compared with the previous 7-day moving average (of 146,087). The current 7-day moving average is 123.6% higher than the value observed around a year ago, according to data compiled by the Centers for Disease Control and Prevention (CDC). In total, more than 40 million Covid cases have been counted in the U.S. since the pandemic began.
