“I would powerfully suggest you get boosted present and not hold for the adjacent iteration of [the vaccine], which we whitethorn not adjacent need,” helium said. “The pharmaceutical companies are preparing to marque a circumstantial booster for [the Omicron variant], but we whitethorn not request that.”

As of Monday morning, 12 countries had reported 165 cases of the Omicron variant to GISAID, a planetary database for the genomic sequencing of viruses. South Africa, which archetypal detected the variant and reported it to the WHO, has recovered 114 cases, followed by 19 successful Botswana, 12 successful the Netherlands, and 5 successful Australia. Four oregon less cases person besides been reported successful the U.K., Belgium, China, Germany, Hong Kong, Israel, and Italy.

On Sunday, Canada became the archetypal state successful North America to observe the Omicron variant, with 2 cases confirmed successful Ontario.

On Monday, Portugal confirmed 13 cases of the variant among a Lisbon-based shot club, including 1 subordinate who had precocious traveled to confederate Africa, according to ABC News.

President Joe Biden volition supply an update connected the administration’s effect to the Omicron variant connected Monday, according to The Hill. Biden met with Fauci and members of the White House COVID-19 Response Team connected Sunday to sermon the caller variant and the latest accusation from the WHO, which labeled Omicron a “variant of concern.”

During the meeting, Fauci told Biden that it volition instrumentality “approximately 2 much weeks” to larn much astir the Omicron variant, The Hill reported, including details astir however it spreads, however terrible it tin be, and however good it tin evade vaccines.

Fauci emphasized that radical should get vaccinated against COVID-19, noting that helium believes the shots are “likely to supply a grade of extortion against terrible cases of COVID.” He besides urged vaccinated radical to get booster shots “as soon arsenic possible” to “provide the strongest disposable extortion from COVID.”

A radical of elder wellness officials successful the Biden medication had a telephone with South African scientists connected Sunday to reappraisal the latest accusation astir the Omicron variant and find adjacent steps, according to The Washington Post.

The medication volition absorption connected booster shots arsenic a cardinal mode to support radical against the caller variant arsenic scientists larn more, the paper reported. The scientists successful South Africa said they expect much breakthrough cases successful radical who are afloat vaccinated, though they aren’t yet definite whether the variant causes terrible disease.

Ongoing Travel Restrictions

On Monday, the U.S. started restricting question for radical from 8 countries: Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, and Zimbabwe. The European Commission, Canada, and the U.K. person besides barred travelers from countries successful confederate Africa.

Some countries person enactment stricter question bans successful spot by barring each overseas travelers, according to The New York Times. Also connected Monday, Japan joined Israel and Morocco successful closing borders to everyone successful an effort to forestall the Omicron variant from spreading.

Australia besides announced that it would hold its program to reopen borders to planetary students, skilled migrants, and travelers from Japan and South Korea, the paper reported. Health officials volition usage the 2-week hold to survey whether the Omicron variant is much contagious than the Delta variant.

Singapore and Malaysia proceeded with plans to reopen their onshore borders connected Monday, portion South Korea announced that it would hold a loosening of social distancing restrictions, the paper reported.

Studying Vaccine Efficacy

During the adjacent 2 weeks, vaccine scientists volition beryllium gathering information connected the caller variant to find however contagious it is and whether the existent vaccines volition support against it, according to The New York Times.

The Omicron variant already makes up astir of the 2,300 caller regular cases successful South Africa’s Gauteng province, the paper reported. New infections person much than tripled crossed the state successful the past week, and trial positivity has accrued from 2% to 9%.

The variant has a “Frankenstein mix” of mutations that could marque it much transmissible and capable to evade immunity, some to vaccination and earthy infection, the paper reported. Doctors successful South Africa person besides reported an summation successful reinfections successful those who already had COVID-19 and recovered. Omicron has astir 50 mutations, including much than 30 connected the spike macromolecule that allows the microorganism to invade quality cells.

“Based connected tons of enactment radical person done connected different variants and different mutations, we tin beryllium beauteous assured these mutations are going to origin an appreciable driblet successful antibody neutralization,” Jesse Bloom, an evolutionary biologist astatine the Fred Hutchinson Cancer Research Center successful Seattle, told the Times.

Some of the mutations person been seen before, but immoderate are unsocial to Omicron. The National Institute for Communicable Diseases successful South Africa is investigating humor from afloat immunized radical against a synthetic mentation of the variant, and results whitethorn beryllium disposable successful astir 2 weeks.

Another squad astatine the Africa Health Research Institute is increasing unrecorded Omicron strains to trial the variant successful blood samples of afloat immunized radical and those who were infected before, the paper reported. Those results whitethorn instrumentality longer but volition supply a amended representation of real-world vaccine efficacy.

Based connected the results, vaccine makers whitethorn beryllium capable to tweak their shots to help. Pfizer and Moderna began investigating their vaccines against Omicron past week and announced they could accommodate their existent vaccines wrong 6 to 8 weeks and vessel the archetypal batches wrong 100 days.

Reporting Mild Symptoms So Far

A South African doctor, who was 1 of the archetypal to fishy that a antithetic coronavirus strain was circulating, said Sunday that symptoms look mild truthful far, according to Reuters.
