White House Chief Medical Adviser Anthony Fauci said Friday it should be about two weeks before scientists fully understand how transmissible and severe the omicron variant of the coronavirus that causes COVID-19 truly is, and until then, people need to get vaccinations and booster shots. 

During a briefing by the White House COVID-19 Response Team, Fauci said South African researchers are leading the way but even their studies will take another week or two to get clinical data. The omicron variant was first identified in South Africa and there are more and longer-term cases to study there, he said. 

The White House response team repeated a message delivered earlier this week by President Joe Biden, that omicron is a variant of concern. Fauci presented new data showing both the Moderna and Pfizer-BioNTech vaccines are markedly boosting antibodies and stressed the need for people to get vaccinated. 

U.S. Centers for Disease Control and Prevention Director Rochelle Walensky said her agency is working with health departments across the United States to help them quickly conduct the genome sequencing necessary to isolate and identify the omicron variant. She said the CDC is far more effective at this process than it was earlier this year. 

Walensky stressed that while the focus is on the omicron variant, the delta variant of the virus is dominant in the U.S. and responsible for 99.9 percent of all cases in the country, especially among the unvaccinated.

White House COVID-19 response coordinator Jeff Zients told reporters that 2.2 million vaccinations – including more than one million boosters – were administered in the U.S. on Thursday, the highest single-day total since May.

Zients said Biden has outlined areas where his administration is taking action to address the potential threat posed by the omicron variant, including vaccinations and boosters for adults, getting kids vaccinated, providing free home testing kits, strengthening travel rules and getting the rest of the world vaccinated.

To the last point, Zients said the U.S. has donated 1.2 billion doses of vaccine for global distribution, more than all other nations combined. Friday alone, he said, the U.S. shipped 11 million doses of vaccine, nine million of which were designated for Africa.

The World Health Organization has recognized Botswana for its efforts to prevent the transmission of HIV from expectant mothers to unborn children. Officials say no children born to HIV-positive mothers this year had the virus.

WHO awarded Botswana the ‘silver tier’ status this week; The silver tier certification is given to countries that have lowered the mother-to-child HIV transmission rate to under five percent and provided prenatal care and anti-retroviral treatment to more than 90 percent of pregnant women.

Botswana has achieved the WHO’s target of an HIV case rate of fewer than 500 per 100,000 live births.

WHO regional director for Africa Matshidiso Moeti, in awarding the certificate in Gaborone on Thursday, said Botswana has demonstrated that an AIDS free generation is possible.

“I want to applaud, this is huge accomplishment by Botswana, which we know has one of the most severe HIV epidemics. This achievement demonstrates that an HIV/AIDS free generation is possible. It also marks an important step towards ending AIDS across the entire continent. Perhaps most importantly, it illustrates the remarkable progress that can be achieved when the needs of mothers living with HIV and their children, are prioritized.”

Botswana has the world’s fourth highest HIV prevalence but has made strides in fighting the virus.

President Mokgweetsi Masisi says the award recognizes the country’s progress towards an HIV-free generation.

“The award is given to Botswana and Batswana as testimony for the success of our efforts as a country in the path to eliminate mother-to-child transmission of HIV. We are excited by this development because we have been battling the HIV/AIDS pandemic for many years. The award therefore, which is the first to be awarded to an African country, demonstrates that our efforts have not been in vain,” Masisi said. Also noting that HIV rate significantly decreased from 37.4 percent in 2003 to 18.4 percent in 2019.

HIV-positive young women, like Tlotlo Moilwa, say the country is on a reassuring path.

“The reasons that drive this change is that the moment a woman is pregnant, they are also tested for HIV and if the result is positive, at that very moment, they enroll for prevention of mother-to-child transmission. This means they cannot infect the unborn baby or even during birth,” Moilwa expressed.

With the country making strides in preventing mother-to-child HIV transmissions, Moilwa says the future is much brighter for her and other HIV-positive women.

“I see a huge change for our future. If you look at the youth living with HIV at the moment, a lot of them got infected at birth. If right now babies are born HIV negative, it means that there will not be HIV positive young people in the future if we are to take care of ourselves.”

According to WHO, 15 countries globally, have been certified for eliminating mother-to-child HIV transmission, but none had an epidemic as large as Botswana.

New Zealand will adopt what is being called a “traffic light” system to curb the spread of COVID-19 and limit the use of lockdowns.

New Zealand’s planned traffic light system has red, amber and green categories, and gives more freedoms to the fully vaccinated. The biggest city, Auckland, is a red zone, mainly because of its high number of COVID-19 cases. Residents there are allowed into cafes, gyms and hairdressers, but there are limits on capacity and proof of vaccination is mandatory.

Much of the country is under the less stringent amber traffic light. The settings will be reviewed in two weeks.

Michael Baker, a public health and epidemiology professor at the University of Otago in Wellington, said the new system is designed to boost vaccination rates.

“There is a band across the central North Island of districts with relatively low vaccine coverage,” he said. “They are automatically going into the red-light classification. This system has two main purposes. One is really to limit transmission of the virus, so it means that if you are indoors, you are indoors with other vaccinated people. But the other thing it does it is sending a very strong message to the unvaccinated, a very strong nudge — you need to get vaccinated. So, I think it will be effective at doing that.”

New Zealand’s Health Ministry estimates that about 86% of the eligible population has received two vaccine doses.

New Zealand has had some of the world’s toughest pandemic controls.

The country’s international borders are expected to remain closed to most foreign nationals until well into next year.

Prime Minister Jacinda Ardern said the omicron variant is a reminder of why New Zealand needs to maintain its “careful approach” to the virus.

With 5 million people, the South Pacific country has recorded 12,000 coronavirus cases and 44 deaths since the pandemic began.

The traffic light system replaces previous coronavirus alert levels. A recent delta variant outbreak forced New Zealand government to abandon its COVID-zero strategy in favor of a strategy that prioritizes containment. The previous approach was designed to eliminate the virus in New Zealand through border closures and strict lockdowns.

Omicron is unlikely to have completely outsmarted the vaccines, experts say, even with its unusual array of mutations. 

There are a lot of unknowns, but they expect that the shots will still do what they do best: Keep people out of the hospital and out of the grave.

Omicron raised alarms when it was first identified during a sharp spike in cases in South Africa. The World Health Organization added it to its list of variants of concern last week.

The virus contains dozens of mutations, including several that are thought to make it more infectious and others that appear to help it evade the immune system.

“But I think it’s still very possible that vaccines will hold up against severe disease, even with those mutations,” said Dr. Carlos del Rio, a professor of medicine at Emory University and president-elect of the Infectious Diseases Society of America.

That’s what has happened with every variant so far. With delta, he noted, “breakthrough” infections among vaccinated people have increased, but those cases are mostly mild.

Omicron seems to be better able than other variants to infect people who have already had COVID-19, according to early data from South Africa. But people with reinfections generally have not been seriously ill.

Experts are recommending boosters for people who can get them. U.S. officials have authorized them for everyone age 18 and older. 

Open questions 

Researchers will have more questions than answers about omicron for the next few weeks while they study the variant. They don’t yet know for sure how the virus stacks up against other variants in terms of how easily it infects or how sick it makes its victims.

Hospitalizations have increased in South Africa during the omicron surge, but it’s not clear if that’s because the virus causes more severe infections or because more people are getting infected. Most of the country is not vaccinated. 

Scientists need to figure out whether the rise in infections is “vaccine failure or failure to vaccinate,” said Dr. Walter Orenstein, associate director of the Emory University Vaccine Center.

“If it’s vaccine failure, is it a problem of time since the last dose and waning immunity?” Orenstein said. 

Though it does not yet seem to be necessary, some companies are working on modifying their vaccines to better protect against the new variant.

Moderna and the Pfizer-BioNTech partners say they can have a new vaccine ready in about three months. Johnson & Johnson says it is working on a new version but did not give a timeline. Oxford University told Reuters news agency that the vaccine it produces with AstraZeneca is still highly effective but that it can quickly update it if necessary. 

Many companies have started developing modified vaccines against previous variants, but none has gone to regulators for approval.

The U.S. Food and Drug Administration says it will not require drugmakers seeking approval for their updated vaccines to go through a process as lengthy as the one for the original versions. Much like with the annual flu vaccine, a few tests for safety and immune response will do.

Multiple cases of the omicron coronavirus variant have been detected in New York, health officials said Thursday, including a man who attended an anime convention in Manhattan in late November and tested positive for the variant when he returned home to Minnesota.

In addition to the conventioneer, tests showed five other people recently infected with COVID-19 had the variant, health officials said. They included a person in the city’s Long Island suburbs who had recently traveled to South Africa, residents of Brooklyn and Queens, and another case possibly linked to travel.

“No cause for alarm. We just want to make sure that the public is aware of information when we receive it,” said Governor Kathy Hochul.

New York City Mayor Bill de Blasio said the geographic spread of the positive tests suggested the variant was undergoing “community spread” in the city and wasn’t linked to any one event.

The news came a day after the U.S. announced its first case of the variant had been detected in California, in a person who had recently traveled to South Africa.

Officials reported another case Thursday in a Colorado woman who had recently traveled to southern Africa.

The Anime NYC 2021 convention Nov. 19-21 drew about 50,000 people, according to event organizers, and attendees were required to wear masks and show proof of having received at least one dose of a COVID-19 vaccine.

Officials in New York said they were working to trace attendees of the convention, which was held at the Jacob K. Javits Convention Center as New York City prepared to host the annual Macy’s Thanksgiving Day Parade and braced for throngs of tourists to return after the U.S. opened up to vaccinated international travelers.

Infections were expected

Officials in the city of 8.8 million said they expected it would be only a matter of time before the new variant was reported in the city. City Health Commissioner Dave Chokshi urged people who attended the event to get tested.

“We should assume there is community spread of the variant in our city,” de Blasio said in a statement.

The Minnesota man began experiencing mild symptoms Nov. 22. He had been vaccinated and received a booster shot in early November, according to health officials in his home state. He sought COVID-19 testing Nov. 24, and his symptoms have subsided, officials said.

Minnesota Health Commissioner Jan Malcolm said the man had not traveled outside the U.S. recently.

“Just given the timing … it seems quite possible, perhaps the most likely, that this transmission happened at the arena convention in New York City, but that’s not definitive,” Malcolm said.

Nov. 22 was the same day the person infected in the California case returned to the U.S. from South Africa. The California traveler, who was vaccinated, developed mild symptoms and tested positive Monday.

Much remains unknown about the new variant, including whether it is more contagious, as some health authorities suspect, whether it makes people more seriously ill, and whether it can thwart the vaccine.

Omicron is classified by the World Health Organization as a “variant of concern” as scientists work to determine how it may compare with the predominant delta variant in terms of transmissibility and severity. Scientists also are studying the degree to which existing vaccines and therapies protect against omicron.

Scientists in South Africa first reported it, but the samples came from several countries in southern Africa. And health officials in the Netherlands now say it was found there prior to the South Africa detection.

‘Get vaccinated’

As comfort over air travel returns, it’s inevitable that new variants like omicron will spread from country to country and state to state, said professor Danielle Ompad, an epidemiologist at New York University’s School of Global Public Health.

“We shouldn’t panic, but we should be concerned,” she said.

Hochul said the case involving the Minnesota visitor underlined the need for everyone who is eligible to get vaccinated against COVID-19 or receive a booster shot if they have not already.

“There is one way to address this — New Yorkers, get vaccinated, get boosted, and get ready,” the Democrat said.

Japan’s consul general in New York, Kanji Yamanouchi, delivered the opening remarks at the convention.

A spokesperson for the consulate said Yamanouchi was vaccinated and received a booster shot about three weeks ago. He said staffers at the consulate underwent testing as a precaution.

“He had absolutely no problem in his health condition,” said the consulate’s spokesperson, Kenju Murakami, noting Thursday it had been nearly two weeks.

A website for the convention says that Anime NYC is mounted by Leftfield Media, an event company based in Shelton, Connecticut. A company spokesperson did not immediately respond to an email requesting comment.

Peter Tatara, its founder and event director, referred questions to company spokespeople. He said he had been tested “multiple times” since the event.

New York City Council Ben Kallos, who appeared at the event with the Japanese ambassador, said a rapid antigen test taken Thursday showed he was negative for the virus.

“I can attest to the fact that my vaccine was checked and I got a wristband, and the person who tested positive for omicron was also fully vaccinated,” Kallos said, urging his “fellow anime fans” to get tested. “So it goes to show you, even when you follow all the precautions, we’re still seeing breakthrough cases.”
