The Centre for Health Protection of the Department of Health Aug. 23, 2023

The Government of Hong Kong Special Administrative Region's Centre for Health Protection (CHP) of the Department of Health today announced it is closely monitoring a human case of avian influenza A(H5N6) in the Mainland.

The CHP report on August 23, 2023, says the 27-year-old woman lives in Dazhou, Sichuan, and was admitted for treatment on July 22. This report did not disclose how or where she became infected with 'bird flu' nor the outcome.

On July 23, 2023, the Alert Response Level under the Government's Preparedness Plan for an Influenza Pandemic was activated.

From 2014 to date, 86 human cases of avian influenza A(H5N6) have been reported by Chinese health authorities. A high percentage of infections (52%) lead to death.

The CHP says that travelers to the Mainland or other affected areas must avoid visiting wet markets, live poultry markets, or farms. And they should strictly observe personal and hand hygiene when visiting any place with live poultry.

The Food and Agriculture Organization of the United Nations, the World Health Organization (WHO), and the World Organisation for Animal Health urged countries in July 2023 to work together across sectors to save as many animals as possible and to protect people. 

The current outbreaks of avian influenza ("bird flu") have caused devastation in animal populations, including poultry, wild birds, and some mammals. Although primarily affecting animals, these outbreaks pose ongoing risks to humans, says the WHO.

Since the annual flu shot is not designed to be effective against bird flu viruses, the U.S. government has invested in various avian influenza vaccines.

In June 2023, the U.S. Centers for Disease Control and Prevention confirmed about 20 million H5N1 and 12 million H7N9 vaccines were available in the U.S. National Strategic Stockpile.

Regeneron Pharmaceuticals, Inc. today announced that the U.S. Biomedical Advanced Research and Development Authority (BARDA) entered into an agreement with the Company to support the clinical development, clinical manufacturing, and regulatory licensure process of a next-generation COVID-19 monoclonal antibody (mAb) therapy for the prevention of SARS-CoV-2 infections, which cause COVID-19 in people.

The agreement is part of the U.S. Department of Health and Human Services (HHS) 'Project NextGen' initiative to advance innovative vaccines and therapeutics for COVID-19.

Regeneron's most advanced next-generation antibody candidate under this agreement is expected to enter clinical trials in 2023.

For the new COVID-19 program announced on August 22, 2023, HHS will fund up to 70% of Regeneron's costs for certain clinical development activities for a next-generation mAb therapy. 

The new BARDA contract has an estimated value of up to approximately $326 million of government funding.

Regeneron's first COVID-19 mAb cocktail, REGEN-COV, was granted Emergency Use Authorization in November 2020, with nearly 3 million doses delivered to the U.S. Government between 2020 and 2022.

"We're pleased to expand our longstanding BARDA relationship, which is predicated on Regeneron's decades of investment in deep scientific research and enabling technologies," said Leonard S. Schleifer, M.D., Ph.D., Board Co-Chair, President and Chief Executive Officer of Regeneron, in a press release.

"Although COVID-19 has moved to an endemic stage, many people – including those with immunocompromising conditions – continue to face exposure that impacts their everyday life and could cause serious health consequences."

Previously, the U.S. CDC wrote some immunocompromised people benefit from mAb therapy instead of COVID-19 vaccination.

Under the NextGen project structure, Regeneron independently invents and proposes an antibody candidate, which BARDA and Regeneron will evaluate and agree upon for further development, manufacturing, and regulatory activities.

BARDA and Regeneron have previously worked together to deliver novel medicines for Ebola.

The new program announced today falls under Regeneron and BARDA's ongoing Other Transactions Agreement initiated in 2017 to develop a portfolio of antibodies targeting up to ten pathogens that pose significant risks to public health.

U.S. CDC RSV detection map August 22, 2023

In the United States, the timing of seasonal respiratory syncytial virus (RSV) outbreaks throughout the country is generally reported between October - April most years.

The 2022–23 season it started later than in 2021–2022 but earlier than prepandemic seasons, suggesting a return toward normal seasonality.

Furthermore, the state of Florida is often a bell-weather state for RSV detections, as it is in 2023.

Florida’s RSV season is longer than the rest of the nation and has distinct regional patterns. For this reason, the state is segmented into five RSV regions, each with its own season. 

The Florida Department of Health recently announced RSV activity during week #33 had increasing detection and admission rates.

As of August 19, 2023, two RSV outbreaks were confirmed in Martin County, located north of Jupiter. Last week, one RSV outbreak occurred in Jacksonville, Florida.

In the U.S., RSV infections cause thousands of hospitalizations among young children and adults aged ≥65. The U.S. Centers for Disease Control and Prevention (CDC) RSV detection 5-week moving average graphs for each state are displayed at this link.

This RSV season, the U.S. government has approved RSV vaccines and monoclonal antibody therapeutics available in specific clinics and pharmacies as of August 22, 2023.

The CDC says people should speak with a healthcare provider if these new therapeutics are appropriate for their health.

Novavax, Inc. today announced that its updated protein-based XBB COVID vaccine candidate induced neutralizing antibody responses to the EG.5.1 and XBB.1.16.6 subvariants in small pre-clinical studies.

As of August 22, 2023, SARS-CoV-2 coronavirus XBB sublineage variants are overwhelmingly responsible for the majority of current COVID-19 cases in the U.S. and European Union.

"Our data have shown that Novavax's protein-based COVID vaccine induces broadly neutralizing responses against XBB subvariants, including EG.5.1 and XBB.1.16.6," commented Filip Dubovsky, President of Research and Development, Novavax, in a press release.

Non-clinical data previously showed that Novavax's COVID vaccine candidate induced functional immune responses for XBB.1.5, XBB.1.16, and XBB.2.3 variants, indicating a broad response that could potentially be applicable for forward-drift variants.

Novavax is submitting applications for its XBB.1.5 COVID vaccine candidate to regulatory authorities globally.

Novavax COVID-19 vaccine brands (Nuvaxovid, CovoVax, NVX-CoV2373, TAK-019) have been authorized in about 40 markets.

The Novavax COVID-19 Vaccine, Adjuvanted, has not been approved or licensed by the U.S. FDA but is authorized for emergency use. Novavax vaccines are available in specific clinics and pharmacies in the U.S.

US FDA approval Aug, 21, 2023

The U.S. Food and Drug Administration (FDA) today approved ABRYSVO™, the first vaccine approved for use in pregnant women to prevent lower respiratory tract disease (LRTD) and severe LRTD caused by respiratory syncytial virus (RSV) in infants from birth through six months of age.

Abrysvo is approved for use at 32 through 36 weeks gestational age of pregnancy, says the FDA.

Previously, the FDA approved Pfizer Inc.'s Abrysvo in May 2023 to prevent LRTD caused by RSV in individuals 60 and older.

"RSV is a common cause of illness in children, and infants are among those at highest risk for severe disease, which can lead to hospitalization," said Peter Marks, M.D., Ph.D., director of the FDA's Center for Biologics Evaluation and Research, in a press release on August 21, 2023.

"This approval provides an option for healthcare providers and pregnant individuals to protect infants from this potentially life-threatening disease." 

Recently, the FDA approved Beyfortus™ for infants born during or entering their first RSV season and for children up to 24 months of age who remain vulnerable to severe RSV disease through their second RSV season.

On July 17, 2023, Beyfortus became the first extended half-life monoclonal antibody offering passive immunization to prevent LRTI caused by RSV. 

RSV is a highly contagious virus that causes respiratory infections in individuals of all age groups, causing frequent outbreaks. Most individuals can be expected to be infected with RSV by the time they reach two years of age, says the FDA.

In most parts of the U.S., RSV circulation is seasonal, typically starting in Florida and peaking in the winter.

A study published by PLOS Medicine in July 2023 concluded RSV disease burden is high in the nearly 600 million children under five living in 121 low-income and middle-income countries. The peak age of community-based RSV incidence is 4.8 months.

A recent study concluded the high proportion of children too young to be vaccinated among unvaccinated Invasive meningococcal disease (IMD) cases suggests that starting the vaccination earlier may prevent more of these cases. 

The JAMA Network published an Original Investigation on a screening cohort study and matched case-control study on August 18, 2023, which found high effectiveness of a 4-component recombinant protein–based (4CMenB) vaccination and more significant reduction in incidence rate ratios (IRR) for early-start vaccination schedules in preventing invasive serogroup B meningococcal disease.

This case-control study represents the most comprehensive multiregional evaluation of the effectiveness of 4CMenB vaccination in the pediatric population of Italy.

Vaccine effectiveness (VE) data obtained from a large group of serogroup B IMD cases with the simultaneous application of 2 independent computational methods (screening and case-control) are unique to the literature.

And VE was firmly greater than 90% in children old enough to receive the first vaccine dose.

Regional differences in the vaccination schedule allowed population-based comparison of outcomes and confirmed the greater efficacy associated with early-start strategies. At the same time, a lack of protection in the very early months of life was apparent even when starting immunization at age two months, prompting the identification of extended prevention strategies.

Current, population-based evidence about VE and reduction in IRRs associated with 4CMenB has been reported in studies conducted in the UK, Australia, Canada, Portugal, and Italy, with heterogeneous methods and across different healthcare settings and age groups. 

The estimates of VE for 4CMenB ranged from 59% to 100% in fully vaccinated cohorts.

PAHO Chikungunya outbreak map August 2023

A Perspective was recently published highlighting a seldom discussed and hard-to-spell mosquito-transmitted disease's impact on thousands of people's health in 2023.

Chikungunya is an arboviral disease caused by the chikungunya virus (CHIKV), afflicting tropical and sub-tropical countries in 2023. Chikungunya outbreaks are primarily found in Africa, Asia, Brazil, and the Indian subcontinent.

For example, about 324,000 chikungunya cases have been reported in the Americas in 2023. As the Republic of Paraguay's ongoing Chikungunya outbreak confirms, this disease can be devastating.

Furthermore, it has been identified as a priority pathogen by the Coalition for Epidemics Preparedness Innovations (CEPI) and an emerging infectious disease.

And its impact has been measured.

Recent studies suggest that disability-adjusted life years (DALYs) due to CHIKV infection are as high as 106,089 DALYs lost globally.

The good news in 2023 is that significant progress has been made in developing several CHIKV vaccine candidates to prevent the disease.

Recently, Vaneva SE's VLA1553 monovalent, single-dose, live-attenuated vaccine candidate was assigned by the U.S. FDA a Prescription Drug User Fee Act review goal date at the end of 2023.

This perspective article published by the journal Nature on August 18, 2023, summarizes CEPI's efforts and strategic considerations for developing a CHIKV vaccine.

U.S. TSA August 2023

The Transportation Security Administration (TSA) recently announced that it was expanding TSA PreCheck® with Telos Corporation at ten airports in the U.S.

Telos began enrolling its first applicants during trial periods in Annapolis, Md., Chantilly, Va., Ashburn, Va., and Las Vegas. 

Since TSA first launched the TSA PreCheck application program for low-risk travelers in December 2013, active membership in the program has grown to more than 15 million passengers.

About 99% of TSA PreCheck® passengers wait less than 10 minutes at 200 airports.

“TSA PreCheck is a trusted traveler program that improves overall aviation security and provides time and convenience benefits to its members,” said TSA Administrator David Pekoske in a press release on August 15, 2023.

“This expansion of enrollment providers will increase the network of locations where applicants may go to complete their TSA PreCheck membership.”

Moving forward, TSA PreCheck members may renew their memberships online with Telos or IDEMIA (TSA PreCheck’s original enrollment provider), regardless of who they enrolled with initially.

As of August 20, 2023, TSA reported airport screening activity had regained volumes last seen in 2019.

The U.S. Department of State issued an updated Level 1 travel advisory for the Argentine Republic on August 18, 2023.

The State Department says visitors should exercise standard precautions when visiting Argentina in 2023, as some areas have increased risk.

For example, the City of Rosario has been issued a Level 2: Exercise Increased Caution advisory.

The State Department says criminal elements are active in Rosario (Santa Fe province), increasing civil unrest.

Additionally, U.S. Embassy personnel are required to give advance notice before traveling to Rosario, which is located about 300 km northwest of Buenos Aires.

In 2022, Statista reported Argentine Patagonia received nearly 3.9 million overnight visitors, with January welcoming about 454 thousand people.

If you decide to travel to Argentina, enrolling in the free Smart Traveler Enrollment Program makes it easier to be located in an emergency.

From a health perspective, the U.S. CDC suggests various travel vaccinations, including for dengue outbreaks, when visiting Argentina in 2023.

GAVI the Vaccine Alliance August 2023

Gavi today reported the Republic of Kenya is innovating to help every eligible child get four malaria vaccine doses in 2023.

As of August 18, 2023, about 96.5% of eligible children in Vihiga County in Kenya have received at least one RTS,S vaccine dose.

However, only 30% of eligible children in Vihiga are yet to complete the four-dose regimen that maximizes the WHO-approved malaria vaccine's effectiveness.

Part of the so-called "Lake-endemic region" in Kenya, a particularly mosquito-plagued set of districts abutting Lake Victoria, Vihiga has been offering malaria vaccinations since 2019.

The positive impact of malaria vaccination is already being measured.

More than a million Gavi-supported RTS,S (Mosquirix™) vaccine doses have been administered to some 400,000 children across the Lake-endemic counties, and Dr Abdourahmane Diallo, WHO Kenya Representative, confirms that those jabs, in concert with other malaria-control measures, have led to a demonstrable decline in case" .

The U.S. CDC Kenya"s Amy Herman-Roloff quantifies that decline at 50%.

The precise burden of malaria in sub-Saharan Africa has remained elusive, wrote researchers in an article published by the journal BMC Medicine.

Infection with Plasmodium falciparum is a frequent event for individuals living in stable transmission areas in Afric. Not all new infections cause illness in partdue tof acquired immunity, says the CDC.

In Africa, two malaria vaccines have been in use during 2023.

In addition to malaria, the CDC included Kenya in a recent polio outbreak travel advisory. When visiting polio outbreak areas, the CDC recommends travelers ensure they have been fully immunized.

A cross-sectional study from the Mayo Clinic Study of Aging published on August 16, 2023, aimed to quantify the clinical trial eligibility criteria for lecanemab and aducanumab treatment for people with early Alzheimer's Disease (AD).

These AD therapies, which are not preventive vaccines, recently received U.S. FDA authorization.

The data indicates that few people are eligible for the anti-beta amyloid monoclonal antibody (mAbs) therapies.

Two hundred thirty-seven participants (mean age 80.9) with mild cognitive impairment or mild dementia and increased brain amyloid burden comprised the study sample.

The mAb aducanumab trial's exclusion criteria reduced the number of available participants, narrowing those eligible to 12 (5.1% of 237).

The common exclusions related to other chronic conditions and neuroimaging findings.

"At first glance, applying clinical trial criteria to real-world practice may seem overly conservative," noted Stephen Salloway, MD, of Brown University in Providence, Rhode Island, and co-authors, in a related editorial published on August 16, 2023.

The journal Neurology published this Research Article: Eligibility for Anti-Amyloid Treatment in a Population-Based Study of Cognitive Aging.

The U.S. CDC published a Morbidity and Mortality Weekly Report (MMWR) today that concluded all adults at risk for mpox should receive Bavarian Nordic JYNNEOS® (MVA-BN) vaccine, irrespective of childhood smallpox vaccination status.

Immunologic studies have demonstrated some long-term immunologic memory from childhood smallpox vaccination that is cross-protective against mpox. Still, such immunity might have waned by May 2022, when the global outbreak began.

On August 18, 2023, the MMWR disclosed although persons aged >50 years likely received a childhood smallpox vaccination, they might have more comorbidities and a higher risk for severe mpox than those aged ≤50. 

This study found among 29,984 adults with mpox, those aged >50 years had higher prevalences of immunocompromising conditions and HIV and lower prevalence of symptoms than younger people.

Among 1,020 adults aged >50 with vaccination data, prevalences of pruritus, constitutional symptoms, and hospitalization were lower among those who received the JYNNEOS vaccine than those who had not.

This finding underscores the importance that persons at risk for mpox, particularly adults aged >50 years, receive the recommended JYNNEOS vaccination. JYNNEOS vaccination is recommended for all adults at risk for mpox irrespective of receipt of childhood smallpox vaccination, wrote these researchers.

The JYNNEOS vaccination services remain available in most health clinics and pharmacies in U.S. cities, London, and in various other locations.

It's unknown how long JYNNEOS protection last or if protection might decrease over time, says the CDC. 

On August 3, 2023, the U.S. government ordered an additional $120 million worth of JYNNEOS vaccines.

US CDC flu season trends August 18, 2023

While the 2023-2024 flu season in the Northern Hemisphere is accelerating, influenza infections have already caused significant mortalities in the U.S.

The National Center for Health Statistics (NCHS) Mortality Surveillance data available on August 17, 2023, reported that 6.1% of the deaths during week #32 were due to pneumonia, influenza, and/or COVID-19.

Among the deaths reported during week #32, six listed influenza as an underlying or contributing cause of death on the death certificate.

Additionally, the U.S. Centers for Disease Control and Prevention (CDC) reported the total number of influenza pediatric deaths for this flu season has reached 168.

Furthermore, 1.3% of patient visits reported were due to respiratory illness, including fever, cough, or sore throat.

An analysis published by the Journal of Infectious Diseases on August 1, 2023, found the risk of flu-related intensive care admission was seven-time greater in unvaccinated people in certain countries.

The CDC recommends an annual flu shot for most people six months of age to reduce future deaths.

Updated flu shots are available, over 100 million so far, in health clinics and pharmacies in the U.S. Last flu season, about 173 million flu shots were distributed in the U.S.

The CDC encourages influenza vaccinations before and during the flu season.

Note: The CDC stated on August 18, 2023, the data presented are preliminary and may change as more data are received and processed.
