US CDC polio case map November 2023

The Global Polio Eradication Initiative (GPEI) recently confirmed six countries reported additional polio cases in 2023

These countries include Pakistan, which reported its fifth wild poliovirus type 1 (WPV1) case this year.

According to the GPEI, the other countries include Chad, the Democratic Republic of the Congo (DRC), Guinea, Nigeria, and Somalia, which reported more circulating vaccine-derived poliovirus type 2 cases.

The DRC also reported four more cases involving circulating vaccine-derived poliovirus type 1.

While it has been about three months since the World Health Organization (WHO) confirmed that the spread of the poliovirus remained a Public Health Emergency of International Concern, the WHO continues to remind Member States that the risk of the emergence of polio has increased due to low vaccination coverage. 

Polio is a crippling and potentially deadly disease that affects the nervous system. 

Most people with polio do not feel sick. In rare cases, polio infection causes permanent loss of muscle function (paralysis). Polio can be fatal if the muscles used for breathing are paralyzed or if there is an infection of the brain.

To warn international travelers, the U.S. Centers for Disease Control and Prevention issued an updated Global Polio Alert - Level 2, Practice Enhanced Precautions, Travel Health Notice on September 11, 2023, regarding polio outbreaks and poliovirus detections in 31 countries.

The CDC says that before visiting any of these destinations, adults who previously completed the full, routine polio vaccine series may receive a single, lifetime booster dose of the polio vaccine.

As of November 2023, various polio vaccines are available worldwide.

Since the launch of the World Health Organization's (WHO) global strategy to accelerate the elimination of cervical cancer three years ago, a further 30 countries, including Bangladesh, Indonesia, and Nigeria, have introduced a Human papillomavirus (HPV) vaccine into their vacation schedules.

As of November 17, 2023, 140 countries have now introduced HPV vaccinations into national programs.

Governments and communities are leading the way by declaring commitment and developing strategies to eliminate HPV cervical cancer, a sexually transmitted disease.

On Cervical Cancer Elimination Day of Action, Member States have a renewed commitment to eliminate this vaccine-preventable cancer.

"In the last three years, we have witnessed significant progress, but women in poorer countries and poor and marginalized women in richer countries still suffer disproportionately from cervical cancer," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General, in a press release.

"With enhanced strategies to increase access to vaccination, screening, and treatment, strong political and financial commitment from countries, and increased support from partners, we can realize our vision for eliminating cervical cancer."

There are effective HPV vaccines that protect males and females against cancers caused by HPV. 

According to the U.S. Centers for Disease Control and Prevention (CDC), these vaccines include 9vHPV, 4vHPV, and 2vHPV. In the U.S., HPV vaccination has been recommended for women since 2006 and for men since 2011. 

As of August 2023, the CDC reported that in 2022, 76% of people aged 13–17 had received one or more HPV vaccine doses.

HPV vaccines are generally available at health clinics and pharmacies in the U.S.

Clinical Infectious Diseases, ciad704 November 2023

During the 2022–2023 influenza season in the United States, the highest influenza-associated pediatric hospitalization rate was reported in a decade.

To understand this uptick in cases, researchers published a Major Article on November 16, 2023, focused on acute respiratory illness-associated emergency department or urgent care (ED/UC) encounters or hospitalizations among those six months–17 years during October 2022–March 2023.

This U.S. CDC-funded analysis estimated influenza A vaccine effectiveness (VE).

Among ED/UC patients, 15.2% of influenza-positive versus 27.1% of influenza-negative patients were vaccinated. The VE was 48% (95% confidence interval [CI], 44%–52%) overall, 53% (95% CI, 47%–58%) among children aged six months–4 years, and 38% (95% CI, 30%–45%) among those aged 9–17 years.

Among hospitalizations, 17.5% of influenza-positive versus 33.4% of influenza-negative patients were vaccinated; VE was 40% (95% CI, 6%–61%) overall, 56% (95% CI, 23%–75%) among children ages six months–4 years and 46% (95% CI, 2%–70%) among those 5–17 years.

These researchers concluded vaccination against seasonal influenza remains the most effective public health strategy to protect against influenza illness and severe complications and that during the 2022–2023 influenza season, vaccination reduced the risk of influenza-associated ED/UC encounters and hospitalizations by less than half (overall VE 40–48%).

US CDC measles outbreak map September 2023

The U.S. Centers for Disease Control and Prevention (CDC) today published a Morbidity and Mortality Weekly Report revealing that global coverage of the measles-containing vaccine (MCV) has declined to the lowest levels since 2008.

The CDC confirmed that from 2000 to 2022, measles vaccination prevented approximately 57 million deaths worldwide.

However, there has been an 18% increase in estimated measles cases and a 43% increase in estimated measles deaths in 2022 compared with 2021.

Measles is highly contagious, infecting about 90% of people following exposure to the virus, says the CDC.

As of November 17, 2023, disruptive measles outbreaks were reported globally.

All six World Health Organization regions have committed to eliminating measles; however, no region has achieved and sustained measles elimination. 

The CDC recently reported that Yemen (28,247) and India (24,301) have reported the most measles cases over the past year.

Measles is a highly contagious, vaccine-preventable disease that requires high population immunity for transmission to be interrupted.

Measles vaccination programs began in the United States in 1963 and continue in 2023.

As of November 2, 2023, a total of 41 measles cases were reported by 18 jurisdictions.

The majority of these measles cases are related to international travelers.

Furthermore, the CDC published a global Watch-Level 1, Practice Usual Precautions, Travel Health Notice in September 2023, identifying measles outbreaks in 39 countries. 

On August 17, 2023, the CDC conducted a COCA webinar urging all healthcare providers to ensure their patients were up to date on the measles vaccination.

Various measles vaccines are available worldwide. In the U.S., most clinics and pharmacies offer measles vaccination services.

PharmaJet® today announced the start of the first human clinical trial for a Venezuelan Equine Encephalitis (VEE) vaccine delivered with PharmaJet Precision Delivery Systems.

The Phase 1 study, sponsored by PharmaJet, aims to identify the optimal dose, vaccination schedule, and delivery system most suitable for use in subsequent broader clinical evaluations of the VEE DNA vaccine candidate.

VEEV is a mosquito-borne alphavirus that has caused sporadic outbreaks and epidemics in North Central and South America. Aerosolized VEEV is highly infectious with greater mortality rates than natural infection and is listed as a potential biothreat agent with no approved human vaccine or therapeutic.

Disease outbreaks frequently involve equines– horses, donkeys, mules, zebras – and humans.

DNA vaccination has proven particularly effective at eliciting protective immune responses against the alphavirus challenge.

As previously reported, the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) and PharmaJet found, in a non-human primate challenge study, that a prime and single boost by either the intramuscular (Stratis) or intradermal route (Tropis) resulted in humoral and cellular immune responses that provided significant protection against VEEV disease and viremia.

These results paved the way for advancing the candidate vaccine into human trials and approval to proceed was recently granted by the Institutional Review Board (IRB), the Army's Office of Human Research Oversight, and the FDA.

President and CEO of PharmaJet, Chris Cappello, said in a press release, "The PharmaJet Precision Delivery Systems are optimized for field use and have also shown immunogenicity levels higher than with needle-syringe."

"We look forward to the clinical results from the human trial of this promising DNA vaccine candidate with our commercially available needle-free precision delivery systems."

The VEE DNA vaccine candidate is being evaluated as part of a multi-year agreement between PharmaJet and the Joint Science and Technology Office of the U.S. Defense Threat Reduction Agency.

The study, in collaboration with USAMRIID, aims to advance further the clinical assessment of the vaccine with the PharmaJet Precision Delivery Systems: Tropis Intradermal and Stratis Intramuscular.

PharmaJet Systems effectively delivers nucleic acid-based vaccines compatible with military operations and the warfighter environment, in addition to being preferred by end-users compared to other delivery technologies.

According to IDSE News, the recently approved half-life monoclonal antibody offering passive immunization to prevent lower respiratory tract infections in infants caused by the respiratory syncytial virus (RSV) has increased availability.

The U.S. Centers for Disease Control and Prevention (CDC) recommends passive immunization to protect infants under eight months and some older babies at increased risk of severe illness caused by RSV. 

“CDC and FDA are committed to expanding access to this important immunization so that more parents have peace of mind during the winter virus season,” said Dr. Nirav D. Shah, CDC’s principal deputy director, in a press release.

On November 16, 2023, the CDC released more than 77,000 additional 100-mg doses of Beyfortus™ (Nirsevimab-alip) to physicians and hospitals through the Federal Vaccines for Children (VFC) Program and commercial channels.

The co-producer of Beyfortus, Sanofi, stated in October 2023 that demand for this RSV product had been higher than anticipated.

On October 23, 2023, the CDC published a Health Alert Network Health Advisory to provide options for clinicians in the context of a limited supply of Betforus. The CDC previously announced it had transitioned to an allocation-based system for distributing Beyfortus.

As of October 2023, Sanofi's price for Beyfortus through the VFC program is $395.00 for 100mg and $395.00 for 50mg through March 2024.

AstraZeneca CEO Pascal Soriot recently informed Reuters, "We've had to deliver what is needed (for the U.S.), and next year, the volume suddenly will go up quite a bit."

Globally, the 2023 RSV season's activity was generally low or decreasing except in some Europe, Central America, Caribbean countries, and the United States as of mid-November 2023.

In the U.S., there are variations in the timing of RSV outbreaks between regions and between communities in the same area, says the CDC.

WHO TB map

Longhorn Vaccines and Diagnostics today presented new data from an animal study of LHNVD-301, the company's lead tuberculosis (TB) vaccine candidate.

The data presented at The Union World Conference on Lung Health 2023 on November 15, 2023, showed that a mycobacterium tuberculosis (MTB) vaccine could generate broader protection against pathogens susceptible to antimicrobial resistance (AMR).

LHNVD-301 is an unconjugated, peptide-based vaccine that combines a MTB heat shock protein epitope and a peptidoglycan (PGN) epitope.

PGN is a cell wall component of bacteria that plays a vital role in infections.

The combination of heat shock protein and PGN generates broad reactive antibodies.

It represents a novel approach that combats AMR while targeting tuberculosis by combining multiple epitopes specific to MTB and common to gram-positive bacteria into a peptide vaccine.

Longhorn CEO Gerald W. Fischer, MD, commented in a press release, "We are developing LHNVD-301 to address MTB as a global threat and combat AMR."

"Unconjugated peptides targeting epitopes of multiple pathogens enable a cost-effective, easily scalable approach for vaccine development, which is crucial for covering those most at risk for TB."

While TB is an ancient disease, outbreaks caused an estimated 10.6 million infections and 1.3 million deaths in 192 countries and areas in 2022.

As of November 2023, 16 TB vaccines are available globally, and various BCG vaccine candidates are under development.

AMA 2023

UCB announced today that BIMZELX® is commercially available for treating moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.

BIMZELX is the first and only approved psoriasis treatment (humanized IgG1 monoclonal antibody) designed to selectively inhibit two key cytokines driving inflammatory processes – interleukin 17A (IL-17A) and interleukin 17F (IL-17F).

BIMZELX (bimekizumab-bkzx) is available as an autoinjector and a pre-filled syringe.1 BIMZELX may be administered subcutaneously by a healthcare professional, or a patient may self-inject after proper training.

The U.S. Food and Drug Administration approved BIMZELX on October 17, 2023.

People living with moderate-to-severe plaque psoriasis should talk to their healthcare provider to see if BIMZELX may be right for them. However, avoid the use of live vaccines in patients treated with BIMZELX. 

"While the treatment landscape for psoriasis has evolved in recent years, many unmet needs remain for the more than 7.5 million adults in the U.S. living with the disease," said Dr. Jeffrey Stark, Head of Medical, U.S. Immunology, UCB, in a press release on November 14, 2023.

"With BIMZELX now available, patients and their healthcare providers have access to a treatment that has proven to deliver rapid, complete consistently, and maintained skin clearance from the first dose."

The approval of BIMZELX is supported by data from three Phase 3, multicenter, randomized, placebo, and/or active comparator-controlled trials, which evaluated the efficacy and safety of BIMZELX in 1,480 adults.

Patients treated with BIMZELX achieved superior levels of skin clearance at week 16 compared to those who received ustekinumab (ranked secondary endpoint, BE VIVID; p<0.0001), placebo (co-primary endpoint, BE READY and BE VIVID; p<0.0001) and adalimumab (co-primary endpoint, BE SURE; p<0.001), as measured by at least a 90 percent improvement in the Psoriasis Area & Severity Index (PASI 90) and an Investigator's Global Assessment (IGA) response of clear or almost clear skin (IGA 0/1). Ranked secondary endpoints included PASI 75 at week four and PASI 100 (complete skin clearance) at week 16.

Through BIMZELX Navigate, UCB offers tailored patient support to all those with moderate-to-severe plaque psoriasis upon receiving their BIMZELX prescription. Eligible patients living in the U.S. may enroll in BIMZELX Navigate at https://www.bimzelx.com/patient-support.

The AMA's What Doctors Wish Patients Knew™ series provides physicians a platform to share what they want patients to understand about today's healthcare headlines.

The AMA wrote living with psoriasis can be incredibly frustrating and challenging. Itchy, scaly skin can hinder daily activities, affect emotional well-being, and diminish the overall quality of life.

The encouraging news is that there are strategies to ease the challenges of living with psoriasis.

Frontiers in Immunology 2023

Nouscom recently announced the completion of its Series C equity financing, raising $72 million that will be used to continue advancing and expanding Nouscom's wholly-owned clinical pipeline to achieve multiple clinical value catalysts.

As of November 13, 2023, the funding proceeds will support the following initiatives:

Readout from Nouscom's ongoing randomized Phase 2 clinical trial for NOUS-209, an off-the-shelf vaccine targeting 209 shared neoantigens, in combination with pembrolizumab for the treatment of Mismatch Repair/Microsatellite Instable Metastatic Colorectal Cancer.

Final readout from the ongoing Phase 1b study and advancement of NOUS-209 monotherapy in Lynch Syndrome carriers investigating the potential to intercept, prevent, or delay cancer before it occurs. LS carriers have a genetic predisposition to and, consequently, a higher risk of developing certain cancers. Promising initial results from this study were reported on October 31, 2023.

Completion of a Phase 1b study evaluating NOUS-PEV, a personalized cancer immunotherapy, in combination with a checkpoint inhibitor in patients with advanced melanoma and entry into randomized Phase 2 trials in indications with high unmet medical needs.

Nouscom has also exclusively out-licensed VAC-85135, an off-the-shelf immunotherapy developed under a multi-project agreement, which is currently under evaluation in a Phase 1 clinical trial for the treatment of Myeloproliferative Neoplasms sponsored by Janssen Research & Development and Bristol Myers Squibb.

Dr. Marina Udier, Chief Executive Officer of Nouscom, commented in a press release, ".... This financing will allow us to further accelerate development across our wholly-owned clinical portfolio reporting multiple clinical trial readouts, including from our ongoing randomized Phase 2 clinical trial with NOUS-209."

"These Phase 2 data, if positive, have the potential to position Nouscom's neoantigen-based cancer vaccines amongst the most thrilling developments in the field."

According to a Review Article published by the journal Frontiers in Immunology in February 2023, Neoantigen vaccines are based on epitopes of antigenic parts of mutant proteins expressed in cancer cells. These highly immunogenic antigens may trigger the immune system to combat cancer cells.

US CDC Burkina Faso chikungunya outbreak map November 2023

While most chikungunya virus (CHIKV) cases have been reported throughout the Americas in 2023, this mosquito-transmitted virus is causing outbreaks in about 115 countries.

Approximately 320,000 CHIKV cases and over 340 related deaths have been reported worldwide this year.

To alert international travelers, the U.S. Centers for Disease Control and Prevention (CDC) recently published a Level 2 - Practice Enhanced Precautions, Travel Health Advisory, regarding chikungunya outbreaks in Burkina Faso.

As of November 9, 2023, several districts have reported cases.

Burkina Faso Public Health Emergency Response Operations Center confirmed 89 chikungunya cases in Pouytenga in the Center-East region in September 2023.

Senegal, Burkina Faso's west African neighbor, has reported 210 chikungunya cases in 2023.

According to the CDC, chikungunya disease is caused by the virus and is spread to humans through mosquito bites.

If infected, you should seek medical care if you develop fever, joint pain, headache, muscle pain, joint swelling, or rash during or after travel.

If you are pregnant, reconsider travel to Burkina Faso, particularly if you are close to delivering your baby, says the CDC.

Mothers infected around the time of delivery can pass the virus to their baby before or during delivery. Newborns infected in this way are at risk for severe illness, including poor long-term outcomes.

Based on the U.S. Food and Drug Administration's recent approval of the IXCHIQ® Chikungunya Vaccine, Live (VLA1553), this disease can be prevented with a vaccine.

Other CHIKV vaccine candidates are conducting late-stage clinical trials in 2023.

US CDC malaria map 2023

Despite decades of efforts to control malaria outbreaks, there were over 24 million cases in 2021. The African Region continues to shoulder the heaviest malaria burden, comprising 95% of patients globally, reports to the World Health Organization (WHO).

Unfortunately, children are particularly vulnerable during malaria outbreaks, as nearly half a million African children die from malaria every year.

In October 2023, the WHO recommended the programmatic use of malaria vaccines to prevent P. falciparum malaria in children living in endemic areas.

According to Gavi, the Vaccine Alliance, the approved malaria vaccines are delivering positive results.

On November 7, 2023, Gavi confirmed in a news article that the Mosquirix™ (RTS,S/AS01) malaria vaccine reduced mortality from all causes by 13% in children in the age group eligible for vaccination.

In addition to the significant reduction in all-cause mortality, the vaccine was also responsible for a 22% reduction in hospitalization for severe clinical malaria in children eligible for the vaccine.

"This means.....more children are going to be saved from death in Africa," commented John Bawa, PATH Malaria Vaccine Implementation Lead for West Africa.

As of November 2023, the Mosquirix vaccine is available in African countries, including Malawi, Kenya, and Ghana. Eighteen countries across different African regions are set to receive millions of doses over the next few years.

The Mosquirix vaccine was created in 1987 as part of a collaboration between GlaxoSmithKline and the Walter Reed Army Institute of Research that began in 1984.
