Omicron estimated to be 2.9% of COVID-19 variants in U.S. – CDC

December 14, 2021; 12:11 PM EST

(Reuters) – The Omicron variant was estimated to be 2.9% of the COVID-19 variants circulating in the United States as of Dec. 11, according to data from the U.S. Centers for Disease Control and Prevention.

For the week ended Dec. 4, Omicron constituted 0.4% of all variants in the country, based on the specimens sequenced.

The agency also estimated that the fast-spreading variant, first detected in South Africa, Botswana and Hong Kong in late November, was 13.1% of circulating COVID-19 variants in New Jersey, New York, Puerto Rico and Virgin Islands for the week ended Dec. 11.

The first known U.S. Omicron case was identified on Dec. 1 in a fully vaccinated person who had traveled to South Africa. The CDC said the earliest date of symptom onset was Nov. 15 in a person with a history of international travel.

The 7-day moving average of daily new cases increased 37.3% from the previous average, with the Delta variant predominant in the United States. The Delta variant accounts for over 96.7% of all U.S. cases, according to CDC data.

The United States on Sunday reached 800,000 coronavirus-related deaths, a Reuters tally showed, as the nation braces for a potential surge in infections because of more time spent indoors as a result of winter holidays and colder weather.

The World Health Organization said on Sunday that while preliminary findings from South Africa suggest Omicron may be less severe than Delta, it remains unclear as to what extent Omicron may be inherently less virulent.

Former FDA commissioner Scott Gottlieb on Twitter questioned whether the 3% accurately reflected the prevalence of the variant here but said it was clear the incidence of Omicron is rising quickly.

AI can help predict whether a patient will respond to specific tuberculosis treatments, paving way for personalized care

Tuberculosis is the world’s deadliest bacterial infection. It afflicted over 10 million people and took 1.3 million lives in 2022. These numbers are predicted to increase dramatically because of the spread of multidrug-resistant TB.

Why does one TB patient recover from the infection while another succumbs? And why does one drug work in one patient but not another, even if they have the same disease?

People have been battling TB for millennia. For example, researchers have found Egyptian mummies from 2400 BCE that show signs of TB. While TB infections occur worldwide, the countries with the highest number of multidrug-resistant TB cases are Ukraine, Moldova, Belarus and Russia.

The COVID-19 pandemic set back progress in addressing many health conditions, including TB.

Researchers predict that the ongoing war in Ukraine will result in an increase in multidrug-resistant TB cases because of health care disruptions. Additionally, the COVID-19 pandemic reduced access to TB diagnosis and treatment, reversing decades of progress worldwide.

Rapidly and holistically analyzing available medical data can help optimize treatments for each patient and reduce drug resistance. In our recently published research, my team and I describe a new AI tool we developed that uses worldwide patient data to guide more personalized and effective treatment of TB.

Predicting success or failure

My team and I wanted to identify what variables can predict how a patient responds to TB treatment. So we analyzed more than 200 types of clinical test results, medical imaging and drug prescriptions from over 5,000 TB patients in 10 countries. We examined demographic information such as age and gender, prior treatment history and whether patients had other conditions. Finally, we also analyzed data on various TB strains, such as what drugs the pathogen is resistant to and what genetic mutations the pathogen had.

Looking at enormous datasets like these can be overwhelming. Even most existing AI tools have had difficulty analyzing large datasets. Prior studies using AI have focused on a single data type – such as imaging or age alone – and had limited success predicting TB treatment outcomes.

We used an approach to AI that allowed us to analyze a large and diverse number of variables simultaneously and identify their relationship to TB outcomes. Our AI model was transparent, meaning we can see through its inner workings to identify the most meaningful clinical features. It was also multimodal, meaning it could interpret different types of data at the same time.

Once we trained our AI model on the dataset, we found that it could predict treatment prognosis with 83% accuracy on newer, unseen patient data and outperform existing AI models. In other words, we could feed a new patient’s information into the model and the AI would determine whether a specific type of treatment will either succeed or fail.

We observed that clinical features related to nutrition, particularly lower BMI, are associated with treatment failure. This supports the use of interventions to improve nourishment, as TB is typically more prevalent in undernourished populations.

We also found that certain drug combinations worked better in patients with certain types of drug-resistant infections but not others, leading to treatment failure. Combining drugs that are synergistic, meaning they enhance each other’s potency in the lab, could result in better outcomes. Given the complex environment in the body compared with conditions in the lab, it has so far been unclear whether synergistic relationships between drugs in the lab hold up in the clinic. Our results suggest that using AI to weed out antagonistic drugs, or drugs that inhibit or counteract each other, early in the drug discovery process can avoid treatment failures down the line.

Ending TB with the help of AI

Our findings may help researchers and clinicians meet the World Health Organization’s goal to end TB by 2035, by highlighting the relative importance of different types of clinical data. This can help prioritize public health efforts to mitigate TB.

While the performance of our AI tool is promising, it isn’t perfect in every case, and more training is needed before it can be used in the clinic. Demographic diversity can be high within a country and may even vary between hospitals. We are working to make this tool more generalizable across regions.

Our goal is to eventually tailor our AI model to identify drug regimens suitable for individuals with certain conditions. Instead of a one-size-fits-all treatment approach, we hope that studying multiple types of data can help physicians personalize treatments for each patient to provide the best outcomes.

  • IVI will complete the technology transfer by 2025
  • Oral Cholera Vaccine to be manufactured by Biological E. Limited for India and international markets

 

March 20, 2024, SEOUL, Republic of Korea and HYDERABAD, India — The International Vaccine Institute (IVI), an international organization with a mission to discover, develop, and deliver safe, effective, and affordable vaccines for global health, today announced that it has commenced a technology transfer of simplified Oral Cholera Vaccine (OCV-S) to Biological E. Limited (BE), a leading India-based Vaccines and Pharmaceutical Company.

 

Following the signing of a technology license agreement in November last year, IVI has begun providing the technical information, know-how, and materials to produce OCV-S at BE facilities and will continue to support necessary clinical development and regulatory approvals. IVI and BE entered this partnership during an unprecedented surge of cholera outbreaks worldwide and aim to increase the volume of low-cost cholera vaccine in India as well as the global public market.

 

IVI will complete the technology transfer by 2025 and the oral cholera vaccine will be manufactured for India and international markets by Biological E. Limited.

 

Dr. Jerome Kim, Director General of IVI, said: “In an era of heightened risk of poverty-associated infectious diseases such as cholera, the world needs a sustainable source of high-quality, affordable vaccines and committed manufacturers to supply them. We are pleased to partner with Biological E., a company with a proven history of making life-saving vaccines accessible globally, to address this supply gap and protect communities from this deadly, though preventable, disease.”

 

Ms. Mahima Datla, Managing Director, Biological E. Limited, said: “We are glad to be in collaboration with IVI for the manufacture of simplified Oral Cholera Vaccine. Our efforts are aimed to not only combat the disease but to also be part of a sustained legacy of innovation, collaboration, and health stewardship. Together with IVI, we are happy to be shaping a healthier and more resilient future by making this vaccine accessible globally.”

 

This technology transfer and licensing agreement is the sixth of its kind for IVI, transferring such technology to manufacturers in India, the Republic of Korea, Bangladesh, and South Africa. All these partnerships have led to or seek to achieve, pre-qualification (PQ) from the World Health Organization, a designation that enables global agencies such as UNICEF to procure the vaccine for the global market. BE already has 9 vaccines with WHO PQ in its portfolio, and IVI and BE will pursue WHO PQ for OCV-S as well, following national licensure in India.

 

Dr. Julia Lynch, Director of IVI’s Cholera Program, said: “The cholera situation is dire, and the availability and use of oral cholera vaccine is an essential part of a multifaceted approach to cholera control and prevention, especially as outbreaks increase and the global vaccine supply remains strained. With more manufacturers like BE entering the market, the future supply situation looks strong. IVI remains committed to ensuring the availability of the oral cholera vaccine and to developing new and improved vaccines that are equally safe, effective, and affordable and made around the world, for the world.”

 

OCV-S is a simplified formulation of OCV with the potential to lower production costs while increasing production capacity for current and aspiring OCV manufacturers. IVI’s development of OCV-S and ongoing technology transfers are part of an institutional strategy to confront cholera with 3 main goals: 1) Ensure supply of OCV 2) Improve cholera vaccines 3) Support OCV use and introduction. The Bill & Melinda Gates Foundation has been supporting IVI’s cholera program since 2000 and is funding this latest technology transfer to BE.

Bolsonaro Indicted By Brazilian Police For Falsifying Covid-19 Vaccine Records

Federal police in Brazil have indicted former President Jair Bolsonaro for falsifying his Covid-19 vaccine card in order to travel to the United States and elsewhere during the pandemic.

Federal prosecutors will review the indictment and decide whether to pursue the case - which would be the first time the former president has faced criminal charges.

According to the indictment, Bolsonaro ordered a top deputy to obtain falsified Covid-19 vaccine records of himself and his 13-year-old daughter in late 2022, right before he flew to Florida for a three-month stay following his election loss.

Brazilian police are also waiting to hear back from the US DOJ on whether Bolsonaro used said cards to enter the United States, which would open him up to further criminal charges, the NY Times reports.

Bolsonaro has repeatedly claimed not to have received the Covid-19 vaccine, but denies any involvement in a plan to falsify his vaccination records. A previous investigation by Brazil's comptroller general concluded that Bolsonaro's vaccination records were false.

The records show that Bolsonaro, a COVID-19 skeptic who publicly opposed the vaccine, received a dose of the immunizer in a public healthcare center in Sao Paulo in July 2021. [ZH: hilarious, Reuters calling the vaccine an 'immunizer.']

The investigation concluded, however, that the former president had left the city the previous day and didn't leave Brasilia until three days later, according to a statement.

The nurse listed in the records as having applied the vaccine on Bolsonaro denied doing so and was no longer working at the center. The listed vaccine lot was also not available on that date, the comptroller general's office said. -Reuters

"It's a selective investigation. I'm calm, I don't owe anything," Bolsonaro told Reuters. "The world knows that I didn't take the vaccine."

During the pandemic, Bolsonaro panned the vaccine - and instead insisted on alternative treatments such as Ivermectin, which has antiviral properties against Covid-19. For this, he was investigated by Brazil's congress, which recommended that the former president be charged with "crimes against humanity," among other things, for his actions during the pandemic.

In May, Brazilian police raided Bolsonaro's home, confiscating his cell phone and arresting one of his closest aides and two of his security cards in connection to the vaccine record investigation.

Brazil's electoral court ruled that Bolsonaro can't run for public office until 2030 after he suggested that the country's voting system was rigged. For that, he has to sit out the 2026 election.
