All these questions stay largely unanswered, although Jha stated it’s “tremendous unlikely” that the variant will render vaccines ineffective.
Specialists say it could take weeks to know if present vaccines are much less efficient in opposition to omicron. Epidemiologist Céline Gounder estimated it could take about two weeks to make this willpower.
Gounder stated in a Twitter thread that scientists do not but understand how omicron might examine to delta when it comes to how infectious it’s and its incubation interval.
What’s taking place in South Africa as omicron spreads?
