The virus's evolution is being studied already, and some vaccine producers have announced new trials to their formulas to face new challenges.
In late November, the Omicron strain was identified for the first time in South Africa. Last week, South African President Cyril Ramaphosa announced that Omicron has a significant percentage of the daily COVID-19 new cases in most South African provinces.
President Ramaphosa tested positive for COVID-19 on Sunday, even after being fully vaccinated. The new COVID-19 variant's spread has reached 77 countries so far.
