With omicron’s excessive variety of mutations, specialists have raised but unanswered questions concerning the threat of reinfection for individuals who have been vaccinated or beforehand contaminated with different variants.
Specialists have applauded the WHO for transferring shortly to sound the alarm on omicron, and South Africa for its quick, clear reporting on the variant.
That may kickstart research over the following few weeks into its contagiousness, virulence, and “immune escape,” which is its skill to withstand an immune response from prior infections or from vaccines, emergency doctor and public well being professor at George Washington College Dr. Leana Wen mentioned.
“The extent of alarm at this level is totally applicable,” Wen instructed USA TODAY. “I might a lot reasonably that we take motion after which discover out that, really this this variant does reply very effectively to the vaccines that now we have.”
Early information is troubling, however incomplete, specialists say.
The outbreak of the omicron variant in South Africa was like a “vertical line,” in line with Dr. Eric Topol, vice chairman for analysis at Scripps Analysis in La Jolla, California.
“We’ve not seen something like that,” he instructed USA TODAY. “The road of slope is way larger than the preliminary delta line.”
Topol mentioned the variety of regarding mutations to the virus might make it extra contagious than earlier variants, and that it’s more likely to have developed in an immunocompromised particular person.
Additionally within the information:
►The CDC issued a degree 4 advisory, its highest, resulting from “very excessive” COVID ranges in eight African international locations, a degree that carries an “keep away from journey” designation. The State Division additionally raised the international locations to degree 4, which implies “don’t journey.”
►The WHO says it skipped two letters within the Greek alphabet — Nu and Xi — in naming the brand new variant omicron as a result of Nu is just too simply confused with the phrase “new” and since Xi is a typical final title, in line with an announcement from the company.
►The CDC this week dropped its share of vaccinated adults in Pennsylvania by almost 5 share factors, to 68.9% from 73.7%, in what apparently was a knowledge correction to weed out duplicates.

Fauci known as President Joe Biden’s choice to limit journey from South Africa and different international locations within the area “prudent” and instructed People to not panic however to take the variant critically as well being specialists study extra about omicron. He additionally urged vaccinations, including that booster photographs give “a really, crucial edge” in averting the virus, together with probably harmful variants.
Scientists look ahead to solutions to key questions
Scientists say there may be nonetheless a lot to study concerning the omicron variant, together with key questions that stay unanswered.
Ashish Okay. Jha, dean of Brown College’s college of public well being, famous three metrics for evaluating the potential impact of a variant in a Twitter thread: if the brand new variant is extra transmissible than the present predominant variant, if the variant causes extra extreme illness and if it’ll render prior infections or vaccines much less efficient.
All these questions stay largely unanswered, although Jha mentioned it’s “tremendous unlikely” that the variant will render vaccines ineffective.
Specialists say it might take weeks to know if present vaccines are much less efficient in opposition to omicron. Epidemiologist Céline Gounder estimated it might take about two weeks to make this dedication.
Gounder mentioned 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 occurring in South Africa as omicron spreads?
In two weeks, South Africa has gone from low transmission charges to fast development in new instances. The spike in instances occurred after a cluster of infections amongst college college students in Pretoria, one of many nation’s capital cities, grew to tons of then hundreds, spreading to Johannesburg, South Africa’s largest metropolis.
Scientists say the brand new variant is probably going liable for as many as 90% of the brand new instances, in line with South Africa’s well being officers.

Regardless of the nation’s case numbers remaining comparatively low with 2,828 new confirmed instances Friday, Mathivha urged hospitals to have essential care beds prepared in case of the “worst case situation” that omicron has the same impact as delta.
Mathivha additionally inspired vaccinations. About 40% of South African adults are at the moment vaccinated, and vaccination charges are decrease amongst youthful adults.
Omicron’s affect on vaccines unclear, however contingency plans already rolling out
Well being specialists have mentioned it’ll possible be weeks earlier than the world has good information about how omicron might scale back the effectiveness of present vaccines, however Moderna has already introduced a three-point technique to fight the brand new variant.
Moderna says its technique for responding to omicron includes three choices for reinforcing COVID-19 vaccination, ought to the variant show problematic for present vaccines.
The three choices, in line with a Friday launch from the corporate: A better dose booster, photographs at the moment being studied which are designed to “anticipate mutations comparable to people who have emerged within the omicron variant” and an omicron-specific booster — which is already within the works.
Andy Slavitt, who beforehand served as Biden’s White Home senior adviser for COVID response, mentioned in a tweet that each Moderna and Pfizer-BioNTech have estimated a vaccine to fight a brand new variant might be developed in about 3 months, with some regulatory and logistical hurtles to comply with.
“If we begin in early December, new vaccines might be accessible by summer time in a lot of the world,” Slavitt tweeted.
A number of media organizations on Friday reported Pfizer-BioNTech is finding out the brand new variant and expects information inside weeks. If warranted, a focused vaccine might be developed inside 6 weeks and ship inside 100 days, the experiences say.
Johnson & Johnson can be testing its present vaccine in opposition to omicron, in line with CNBC.
Professor Andrew Pollard, director of the Oxford Vaccine Group, instructed BBC Radio he was cautiously optimistic present COVID vaccines can be efficient in stopping critical sickness from the omicron variant, including that mutations in omicron seem like in related areas because the mutations in different variants.
“That tells you that regardless of these mutations present in different variants the vaccines have continued to stop critical illness as we’ve moved by way of alpha, beta, gamma and delta,” Pollard, whose workforce developed the AstraZeneca vaccines, mentioned. “Not less than from a speculative standpoint now we have some optimism that the vaccine ought to nonetheless work in opposition to a brand new variant for critical illness however actually we have to wait a number of weeks to have that confirmed.”
