The World Health Organization issued a statement on the 11th saying that the new crown vaccine that has been certified by WHO for emergency use is still effective against the Omicron strain, but the existing new crown vaccine may need to be updated to continue to provide people with sufficient protection.

Experts from the WHO's new crown vaccine composition technical advisory group are currently analyzing evidence related to the "required concern" variant strains, and may revise the recommendations for new crown vaccine strain components accordingly, the statement said
.
According to the transmissibility and pathogenicity of the mutated new coronavirus, the WHO has classified the mutated strains as "requiring attention" or "requiring attention", among which Omicron and Delta are all mutant viruses that "require attention" strains

WHO has also proposed a number of options for updating the programme, including the development of monovalent vaccines against the main circulating variant strains, multivalent vaccines containing antigens from multiple variant strains that "require attention", or the development of more sustained, multivalent vaccines targeting different variants.
