The BA.2.86 Variant: A New Challenge in the Fight Against COVID-19
The battle against COVID-19 has been a relentless one, marked by the emergence of new variants of the virus. While the world grappled with the Alpha, Beta, Delta, and Omicron variants, a new player has entered the scene: BA.2.86. This variant, a descendant of the Omicron strain, is raising questions and concerns among scientists and health officials. In this article, we will delve into what we know about the BA.2.86 variant, its characteristics, potential implications, and how we can continue to navigate the pandemic in its presence.
Understanding the BA.2.86 Variant
1. Origin and Evolution
The BA.2.86 variant, also known as the “stealth Omicron,” is believed to be a sublineage of the Omicron variant (B.1.1.529). It was first identified in Botswana and South Africa in late 2021, where Omicron itself was initially discovered. Like its predecessor, BA.2.86 carries numerous mutations in the spike protein of the virus, which plays a critical role in its ability to infect human cells. These mutations allow it to spread rapidly and, in some cases, partially evade immunity from previous infections and vaccinations.
2. Increased Transmissibility
One of the most concerning features of the BA.2.86 variant is its increased transmissibility. Early data suggests that it may spread more easily than the original Omicron variant, which itself was already highly contagious. This heightened transmissibility has led to a surge in cases in several countries, prompting concerns about overwhelmed healthcare systems and the potential for more severe outcomes.
Potential Implications of the BA.2.86 Variant
Vaccine Evasion and Immunity
The most pressing question surrounding BA.2.86 is its potential to evade immunity gained through vaccination or prior infection. Preliminary data indicates that while some vaccine effectiveness against this variant may be reduced, vaccines still provide substantial protection against severe illness and hospitalization. Booster shots have become a crucial tool in enhancing immunity against BA.2.86 and other variants, emphasizing the importance of keeping vaccination campaigns active and robust.
It’s essential to note that the immune system is a complex and adaptive system. Even if a variant partially evades immunity, the body’s defense mechanisms can still provide a substantial defense against infection and severe disease. Thus, vaccines remain a vital part of our strategy in the fight against BA.2.86.
Antiviral Treatments and Therapeutics
As the virus continues to mutate, the development of antiviral treatments and therapeutics becomes increasingly important. These treatments can offer a lifeline to individuals who contract COVID-19, especially in cases where the virus may partially evade immunity. Research into effective antiviral drugs and monoclonal antibodies that target various strains of the virus, including BA.2.86, is ongoing and holds promise in reducing the severity and duration of illness.
Navigating the BA.2.86 Era
In the face of the BA.2.86 variant and future potential variants, it is crucial to maintain a multifaceted approach to managing the COVID-19 pandemic:
Vaccination and Boosters
Widespread vaccination, including booster shots, remains our most potent tool against the virus. Health authorities must continue to promote and facilitate vaccination for all eligible individuals. Booster programs need to be agile, adapting to emerging variants to ensure ongoing protection.
Public Health Measures
Basic public health measures such as mask-wearing, social distancing, and good hand hygiene continue to be essential in reducing the spread of the virus. These measures not only protect individuals but also contribute to the overall reduction in transmission within communities.
Surveillance and Genomic Sequencing
Vigilant surveillance and genomic sequencing are critical to tracking the emergence of new variants. By identifying these variants early, we can better understand their characteristics and inform public health responses. This data helps guide vaccine development and treatment strategies.
Global Collaboration
The COVID-19 pandemic has highlighted the importance of global collaboration. Variants like BA.2.86 know no borders, and controlling the virus requires coordinated efforts between nations. Sharing knowledge, resources, and vaccines is crucial in ensuring equitable access and a comprehensive response.
Conclusion
The BA.2.86 variant is another twist in the ever-evolving story of COVID-19. While it presents challenges, it’s important to remember that we have faced variants before and adapted our strategies to combat them. The tools at our disposal, including vaccines, treatments, and public health measures, remain effective in mitigating the impact of this new variant.
As we move forward, our focus should be on enhancing our vaccination efforts, developing effective therapeutics, and maintaining the public health measures that have proven effective in reducing transmission. The BA.2.86 variant serves as a reminder that the pandemic is not over, but with continued vigilance and cooperation, we can navigate this new challenge and move closer to a world where COVID-19 is no longer a dominant threat.
United States: The World Health Organization said on Friday that it had approved its first shot of vaccines against the mpox for use in adults, saying that it is a progression toward eradicating the disease in Africa.
More about the news
This approval is significant for organizations like Vaccines Alliance Gavi and UNICEF as they can now purchase it from Bavarian Nordic A/S.
Buying supplies is, however, a challenge since the product is manufactured by only one company.
According to WHO Director-General Tedros Adhanom Ghebreyesus, “This first (authorization) of a vaccine against mpox is an important step in our fight against the disease, both in the context of the current outbreaks in Africa and in future,” ABC News reported.
Previously, the UN health agency endorsed the two-dose mpox vaccine targeting the adult population who are 18 years and above. As for WHO, even though they did not advise the use of the vaccine for people below the age of 18, in particular cases, vaccines can be given to infants, children, and adolescents “in outbreak settings where the benefits of vaccination outweigh the potential risks.”
What more has the WHO recommended?
The WHO has also pointed out that it has been making an “access and allocation mechanism” to execute an even and fair distribution of mpox tests, treatments, and vaccines to the countries that need them most.

WHO has suggested that a dose could be split in the event that there is a shortage of the vaccine since one dose was proven to be 50 percent effective, and it is important to gather more information on the efficacy of the vaccine when used as a single shot.
About the vaccine
The Bavarian Nordic mpox vaccine was earlier named and approved by several developed countries in Europe and North America during the mpox outbreak in the year 2022.
In millions of adults, doses have proven that the vaccine assists in decelerating the virus distribution, but little is known about children.
Director-general of the Africa Center for Disease Control and Prevention said last month that seventy percent of the patients are below the age of 15 in Congo, where the outbreak is most severe, and children under the age of 15 are the majority of fatalities at 85 percent.
However, the WHO noted that more than 120 countries had confirmed more than 103 thousand legion cases of mpox since the start of the outbreak two years ago, ABC News reported.
As of Sunday, it recorded 723 people in well over a dozen countries in Africa have perished from the disease.
United States: The World Trade Center Health Program has been covering the medical expenses for cancer, respiratory ailments, mental health conditions, and musculoskeletal disorders linked to work at the site ever since it was established by an act of Congress and signed into law by President Barack Obama in 2011.
More around the news
Recently, researchers have started to look into cognitive impairment and dementia afflicting first responders at rates far higher than in the general population.
The study findings are urging healthcare providers to be more expressive regarding lobbying the World Trade Center Health Program, which is overseen by the CDC, to include dementia among the illnesses covered.
What more are the experts stating?
According to Benjamin Luft, the director of a program at Stony Brook University that cares for and monitors the health of first responders, “I’m hoping they will,” and “They have a systematic process in which they evaluate the scientific data. We’ve spent a huge amount of time and effort to establish that exposure to the neurotoxins and dust could cause these problems, and so should be eligible for coverage,” the Washington Post reported.

Lust has been working as a senior author of a study whose findings were published this summer and involved more than five thousand respondents who regularly undergone tests for over a decade.
They found that the ones with maximum exposure to the dust, as well as neurotoxic debris at the WTC, would have fourteen times more chances of becoming infected with dementia before the age of 65.
As per Ray Dorsey, a professor of neurology at the University of Rochester, the small-sized ordinary dust particles, which are termed fine particulate matter, could enter the nose and reach the brain to cause damage, the Washington Post reported.
However, as Dorsey said, “The nose is the front door to our brain,” and “Dust and chemicals set up shop in the small area of our brain, then spread to the parts of the brain important for memory.”
United States: A drug has recently received approval for the treatment of obesity in adults and teenagers. It has been proven to be efficient for kids starting from the age of six when taken together with the necessary lifestyle changes – a new study found.
More about the news
A medication called liraglutide, used in adults with obesity, reduced body mass, attenuated weight gain, and enhanced favorable biomarkers in children aged between six and eleven years, research reported in a medical conference on Tuesday, and to the New England Journal of Medicine, ABC News reported.
Following the trial, the company that manufactures the drug, Novo Nordisk, has sought permission from the US authorities to apply the medication in children in that age bracket, the spokesperson said on Tuesday.
Should the medication be approved, it would be the first treatment for the kind of obesity experienced by over 20 percent of kids in the age group of 6 through 11 in the United States, according to the US CDC.

What do the study results show?
According to Dr. Claudia Fox, a pediatric obesity expert at the University of Minnesota, who led the study, “To date, children have had virtually no options for treating obesity,” and “They have been told to ‘try harder’ with diet and exercise,” ABC News reported.
Like most drugs with antiemetic properties, side effects include gastrointestinal effects in those administered the drug, including nausea, vomiting, and diarrhea, among others.
However, physicians and parents would have to research those risks and the absence of knowledge about the safety of employing such drugs in young children.
According to Dr. Melissa Crocker, a pediatric obesity specialist at Boston Children’s Hospital, “Having a medication for that age group, if approved, would be a really nice tool to have, but we’re also going to have to be careful about how widely we start using it,” ABC News reported.

“And I would answer that differently at six than I would at 11,” she added.
About Liraglutide
Liraglutide belongs to a class of drugs known as GLP-1s, which currently boast some of the biggest-selling drugs in the world, such as Wegovy and Mounjaro.
The medications make them resemble hormones that control hunger, feelings of being full or satiated, and digestion. Although this drug is given as a daily injection, it has been approved under the name of Victoza as a treatment for diabetes in adults and in children that are at least ten years of age and for Saxenda under the treatment of obesity affecting adults and children aged between 12 to 17 years.
The new study, also funded by Novo Nordisk, enrolled 82 children with a mean age of 10 and a baseline weight of 70kgs or 154. 2 pounds. In this sample, the average starting BMI was 31, categorizing the childhood population as obese or overweight.
