White House chief medical adviser Anthony Fauci said in an interview with CNN on December 14 local time that the new crown variant virus Omicron strain will definitely become the main source of infection for new crown pneumonia in the United States. Conventional two doses of mRNA vaccine (Pfizer or Modena) are not very effective against it and spread very quickly.
Still, Fauci said, the likelihood of the Omiljun strain causing serious disease is relatively low. In South Africa, where the Aumi kerong strain was first discovered, although the rate of new coronavirus infection has skyrocketed, the hospitalization rate has not surged because of the Omiljun strain. He called on the American people to get the covid-19 vaccine as soon as possible, and said that this is the best way to protect it at present.
