Question

why 2020 is different than 2021 about covid​

Answer 1

Answer:

PARIS: 2020 was a year turned upside-down by the novel coronavirus. But with the prospect of several vaccines coming online and less stringent restrictions, experts say it's possible 2021 will return to a semblance of normality. With a second Covid-19 wave currently battering Europe, the United States battling its third, and Hong Kong facing a fourth, disease specialists say they can't rule out more resurgences in cases and deaths as 2021 gets underway.

France's scientific council, which guides government policy on the pandemic, envisages "several successive waves" of Covid-19 over the winter and well into next year.
