Fauci, director of the National Institute of Allergy and Infectious Diseases, the top authority on COVID-19 in the United States, said that Omicron will also exist in the United States.



As it has already spread in many countries, there will be unconfirmed infections.

Still, he strongly recommended the additional vaccination.



As basic immunity is expanded by receiving booster vaccinations, it is the best way to respond to new mutations at this time.



Some experts expected that the existing vaccine would also have some effect on Omicron as the vaccine made based on the first COVID-19 virus had a significant effect on the delta mutation.



However, I thought it would take 2-3 weeks to check this.
