[FRIAM] Omicron--what we know now

[Merle Lefkoff]

Omicron’s genetic profile is unique from other circulating variants,
meaning it represents a new lineage of the virus.



It is distinct from other variants in another crucial way: There are a
greater number of mutations. Tulio de Oliveira, director of the Center for
Epidemic Response and Innovation in South Africa, said there are more than
30 mutations in the spike protein, the part of the virus that binds to
human cells, allowing it to gain entry.



Scientists are worried that those mutations could make omicron more
transmissible and potentially equipped to defy immune defenses, making
vaccines less effective. The WHO said last week that preliminary evidence
suggests an “increased risk of reinfection” compared with other variants.
