Many days after the lockdown, when the vaccination started, we thought that now we will get rid of covid-19. But this thought is being dusted off by a new variant of covid-19 called Omicron. It is rumored that most vaccines have no effect on this new variant of the virus. The new variant is spreading very fast and also it is the most dangerous variant of covid-19.
new variants continue to appear and omicron is the latest variant at the end of this year. what new variant will appear in 2022, I'm sure it's many times more widespread than omicron LOL
