According to Reuters reporting, AstraZeneca is voluntarily withdrawing its COVID-19 vaccine Vaxzevria as global demand has declined in 2024.

The University of Oxford, Serum Institute of India Pvt. Ltd., and AstraZeneca co-produced Vaxzevria COVID-19 (AZD1222). The European Medicines Agency initially authorized Vaxzevria in February 2021.

The London-based company indicated that the decision to pull Vaxzevria from the global market was due to the "surplus of available updated vaccines" adapted to newer and emerging variants of COVID-19, Reuters reported on May 6, 2024.

"We are incVaxzevria's role Vaxzevria played in ending the global pandemic. According to independent estimates, over 6.5 million lives were saved in the first year of use alone, and over three billion doses were supplied globally," AstraZeneca told The Telegraph in a statement.

Over the past month, other COVID-19 vaccine producers have reported significant decreases in consumer demand.

In the U.S., the Food and Drug Administration recently announced it intends to issue its recommendations for 2024-2025 COVID-19 vaccines in mid-June 2024.

ImmunityBio, Inc. announced today that the drug substance had been completed and successfully qualified for “fill finish” (filling vials and finishing packaging), sufficient for 170,000 doses of 400mcg ANKTIVA®.

ANKTIVA (nogapendekin alfa inbakicept-pmln) is the first U.S. FDA-approved immunotherapy for non-muscle invasive bladder cancer that activates natural killer cells, T cells and memory T cells for a long-duration response.

Coupled with the recent announcement of a partnership with the Serum Institute of India for enhanced BCG vaccine availability, this provides the Company with a significant initial supply of ANKTIVA for commercial and clinical trial use in advance of the full operation of the Company’s drug substance and fill-finish manufacturing plants in California and New York.

In 2024, Anktiva will be priced at $35,800 per dose. The cost of the BCG vaccine is additional.

Since the Company’s merger with NantKwest in 2021, ImmunityBio has made significant capital investments in personnel, plants, and equipment to ensure the global capacity of the ANKTIVA drug product for both the commercial launch and clinical trials in bladder cancer and other tumor types in its pipeline.

Both drug substance and drug product facilities are nearing completion to ensure sufficient capacity and multiple GMP manufacturing sites for ANKTIVA in its approved indication and for clinical trials and future indications.

“Our belief in the importance of this molecule and its potential to evolve immunotherapy to the next level guided our strategic plan to invest for the future with anticipation of ANKTIVA’s approval,” said Rich Adcock, CEO & President ImmunityBio, in a press release on May 7, 2024.

“I’m grateful for our employees and our investors who have supported and believed in our commitment to invest for our long-term vision and future.”

The Company is applying its science and platforms to treating cancers, including developing potential cancer vaccines, immunotherapies, and cell therapies that we believe will sharply reduce or eliminate the need for standard high-dose chemotherapy.

TCompany says these platforms and their associated product candidates are designed to be more effective, accessible, and easily administered than current standards of care in oncology and infectious diseases.

ECDC chikungunya case map April 2024

Valneva SE today reported its financial results for the first quarter ending March 31, 2024, and provided corporate updates.

On May 7, 2024, the Company announced IXCHIQ®, the world's first and only licensed chikungunya vaccine, recorded initial sales of €0.2 million in the first quarter in the U.S.

In a press release, Peter Bühler, Valneva's Chief Financial Officer, commented, "The first quarter performance has been in line with our expectations. We are aiming to further capitalize on the travel industry recovery during the rest of the year (2024), including ramping up sales for IXCHIQ® to support our commercial sales growth while executing on our key R&D milestones."

IXCHIQ® is also under regulatory review in Canada, Brazil, and Europe, where it was granted accelerated assessment by the European Medicine Agency's Committee for Medicinal Products for Human Use. Decisions on these submissions are expected in 2024.

The U.S. Centers for Disease Control and Prevention (CDC) recently adopted the U.S. Advisory Committee on Immunization Practices recommendations, which include the chikungunya vaccine for persons aged ≥18 traveling to a country or territory with a chikungunya outbreak

In addition, the CDC says the chikungunya vaccine may be considered for those traveling to a country or territory without an outbreak but with evidence of chikungunya virus transmission among humans within the last five years. 

Persons aged >65 years, particularly those with underlying medical conditions, are likely to have at least moderate exposure* to mosquitoes OR Persons staying for a cumulative period of 6 months or more. Moderate exposure could include travelers with at least two weeks (cumulative) of exposure to mosquitoes in indoor or outdoor settings.

Chikungunya is a viral disease transmitted to humans through the bites of mosquitoes infected with the chikungunya virus.

As of May 2024, the World Health Organization says chikungunya was identified in nearly 115 countries, primarily in the Region of the Americas.

According to the European Centre for Disease Prevention and Control, approximately 70,000 chikungunya cases and 15 deaths have been reported worldwide in 2024.

NYC Dept Public Health mpox case trends April 2024

New York City's Deputy Commissioner, Division of Disease Control, Celia Quinn, MD, MPH, issued a statement confirming that mpox continues circulating in the city.

As of May 3, 2024, Health Advisory #12 reported the overall number of mpox cases is low compared to the 2022 outbreak. For most of 2023, the NYC averaged about 2 to 20 monthly cases.

Since October, there has been an average of 36 monthly cases, with a peak count of 51 in January 2024.

Of the 256 cases from October 2023 through April 15, 2024:

  • 73% (188) were not vaccinated or had received only one dose,
  • 94% were among men,
  • 3.9% (10) of the infected people were hospitalized,
  • Most were Black or Hispanic and between the ages of 25-44.

NYC confirmed the commercialization of the U.S. FDA-approved JYNNEOS® Mpox Smallpox vaccine is underway. As of May 2024, healthcare providers can order JYNNEOS through their distribution partners to make it available for at-risk individuals at local pharmacies.

Mpox is a contagious disease caused by the monkeypox virus. The U.S. Centers for Disease Control and Prevention and NYC continue to report only Clade II mpox cases in 2024.

Last week, the U.S. Government Accountability Office noted in a May 2, 2024 report that the Strategic National Stockpile (SNS) wasn't clear on how and from whom to request mpox supplies, including causing confusion and delays in mpox vaccine deliveries. 

About 30% of U.S. jurisdictions during the mpox outbreak said the process for requesting SNS inventory did not follow written guidelines.

BioNTech SE today reported financial results for the first three months of 2024, and provided an update on its corporate progress.

Total revenues reported were €187.6 million for the three months in 2024, compared to €1,277 million for the comparative period in 2023.

The Germany-based company stated the year-over-year change was mainly due to lower commercial revenues from the sales of BioNTech’s COVID-19 vaccine worldwide, resulting from endemic-level demand for COVID-19 vaccines.

“In the past weeks, we have reported positive preliminary data for our individualized and off-the-shelf mRNA-based candidates, which further underline the potential of our iNeST and FixVac platforms. We look forward to providing more updates this year across our oncology portfolio, including our bispecific antibody and ADC programs,” said Prof. Ugur Sahin, M.D., CEO and Co-Founder of BioNTech, in a press release on May 6, 2024.

“In the remainder of the year, we plan to develop and commercialize a variant-adapted COVID-19 vaccine and accelerate our clinical development activities towards realizing the full potential of our oncology pipeline with a view to becoming a commercial company with marketed medicines for cancer and infectious diseases.”

BioNTech and Pfizer developed, manufactured, and delivered their Omicron XBB.1.5-adapted monovalent Comirnaty COVID-19 vaccine, which has received multiple regulatory approvals, including full approvals, authorizations for emergency or temporary use, or marketing authorizations, in more than 40 countries and regions.

BioNTech says it is now focused on preparing for variant strain vaccine adaptation to be ready for commercial launch ahead of the upcoming 2024/2025 vaccination season, pending approvals.

ECDC measles outbreaks 2024

As outbreaks of vaccine-preventable diseases continue to occur in European countries, vaccinations and booster doses are recommended. Everyone should check with their healthcare providers to ensure they are up-to-date with recommended vaccines, says the European Centre for Disease Prevention and Control (ECDC).

Recently, the ECDC reported that between March 2023 and the end of February 2024, at least 5,770 measles cases, including at least five deaths, had been reported in the EU/EEA.

The European Union is a political and economic union of 27 European countries, while the European Economic Area is made up of 30 countries, including the EU, Iceland, Liechtenstein, and Norway.

As of 2024, the ECDC says 70% of measles outbreaks have occurred in those under ten, and 78% were contracted outside their countries or due to imported cases.

To inform international travelers, the U.S. Centers for Disease Control and Prevention recently listed the top ten international measles outbreaks led by Kazakhstan  (27,280), Azerbaijan, Iraq, and India.

In the U.S., the spike in measles cases this year was primarily reported in Chicago, Illinois.

It has been about three decades since the U.S. Food and Drug Administration approved the first monoclonal antibody. Since then, antibody engineering has dramatically evolved. 

The recent pandemic was the first time monoclonal antibody-based therapies were produced in significant quantities to combat a new infectious disease. Globally, clinics administered hundreds of thousands of antibody injections over the first two years of the pandemic.

Antibody therapy worked... until it didn't.

The U.S. CDC says the infectious virus's rapid evolution outpaced the benefits derived from antibodies.

According to Michael Dumiak's article published by IAVI on April 25, 2024, this experience and other issues have researchers assessing the future of antibody therapies for treating or preventing infectious diseases, including some of the most complicated pathogens, such as HIV and antibiotic-resistant bacteria.

A potential application is blocking mother-to-child transmission of HIV during birth and through the breastfeeding period.

"We are in the position that if you want more antibodies for infectious disease, you need to be very cautious," says Rino Rappuoli, scientific director of the Biotecnopolo di Siena Foundation in Italy.

The unedited, complete IAVI article is posted at this link.

Note: As of May 5, 2024, the U.S. FDA has not approved an HIV vaccine candidate.

US CDC Oropouche fever case map April 2024

In 2024, there has been an increase in the detection of Oropouche fever outbreaks in areas of the Region of the Americas.

The U.S. Centers for Disease Control and Prevention (CDC) recently confirmed Oropouche fever outbreaks in parts of Brazil, Bolivia, and Peru.

For example, between 2023 and early 2024, 1,066 human cases of the Oropouche virus were registered in the Brazilian state of Amazonas.

To alert international travelers to this health risk, the CDC issued a Level 1, Practice Usual Precautions, Travel Health Advisory, saying Oropouche fever is spread through the bites of infected midges (flies) and Culicoides paraensis mosquitoes.

The illness is often mistaken for dengue.

The Pan American Health Organization (PAHO) says travelers to these areas should seek medical care if they develop high fever, headache, muscle aches, stiff joints, nausea, vomiting, chills, or sensitivity to light during or after travel. 

Most people recover without long-term effects. 

Symptoms typically start 4–8 days after being bitten and last 3–6 days.

Oropouche fever has no cure or specific therapy, so treatment is symptomatic. Oral analgesics and anti-inflammatory agents can help with headaches and body pains.

As of May 2024, no licensed vaccines or specific antiviral treatments for Oropouche fever exist. However, recent clinical studies have used peptide vaccines to develop epitope-based vaccines, which could lead to potential use in the future.

New research presented at the Pediatric Academic Societies confirms rotavirus vaccines do not cause significant outbreaks of the disease in neonatal intensive care units (NICUs).

These researchers concluded that vaccine-strain rotavirus transmission in the NICU was rare and without clinical consequences.

The study found that 99.3% of non-vaccinated patients exposed to vaccinated patients did not test positive for the disease. Non-vaccinated patients who contracted rotavirus had no symptoms after 14 days.

Announced on May 3, 2024, these findings are significant because many NICUs avoid vaccinating against rotavirus due to a theoretical risk of transmission, yet some infants are too old to receive the vaccine once discharged from the NICU.

According to researchers, preterm infants are at higher risk of the highly contagious but preventable virus, yet few receive the vaccine in hospital settings.

This concern is because the rotavirus vaccine contains a weakened form of the virus.

“Immunization with rotavirus vaccine has been standard practice in the Children’s Hospital of Philadelphia NICU since 2007, and the safety of this practice was supported by retrospective clinical data published in Pediatrics in 2014 – however, this remains an uncommon practice in NICUs across the United States,” said Kathleen Gibbs, MD, the study’s lead neonatologist from Children’s Hospital of Philadelphia, in a press release.

“Our yearlong, prospective study, done in collaboration with the U.S. Centers for Disease Control and Prevention, suggests that the benefits of vaccinating NICU patients against rotavirus outweigh the risks. Inpatient vaccination allows protection of a vulnerable population against a common, preventable cause of severe diarrheal illness.”

According to researchers at the University of Minnesota, a common diabetes drug has been found to reduce the amount of SARS-CoV-2 coronavirus and lower the risk of COVID-19 rebound symptoms when administered early during non-severe illness.

"The results of the study are important because COVID-19 continues to cause illness, both during acute infection and for months after infection," said Carolyn Bramante, MD, principal investigator and an assistant professor at the U of M Medical School, in a press release on May 2, 2024.

This study was published in the journal Clinical Infectious Diseases on May 1, 2024.

These researchers wrote that in this randomized, placebo-controlled phase 3 clinical trial of outpatient treatment of SARS-CoV-2, metformin significantly reduced the viral load.

The mean SARS-CoV-2 viral load was reduced 3.6-fold with metformin relative to placebo (−0.56 log10 copies/mL; 95% confidence interval [CI], −1.05 to −.06; P = .027).

Those who received metformin were less likely to have a detectable viral load than placebo at day five or day 10 (odds ratio [OR], 0.72; 95% CI, .55 to .94).

Viral rebound, defined as a higher viral load on day ten than on day 5, was less frequent with metformin (3.28%) than with placebo (5.95%; OR, 0.68; 95% CI, .36 to 1.29).

The metformin effect was consistent across subgroups and increased over time.

In a related commentary, the study authors wrote, "This study makes a strong case for a potential effect of metformin on COVID-19.... and  prompts a reevaluation of existing data in support of its use."

The Rainwater Charitable Foundation, The Parsemus Foundation, UnitedHealth Group, and Fast Grants funded the clinical trial. Drs. Bramante and Jacinda Nicklas' time was supported by the National Institutes of Health

US CDC polio travel health advisory April 2024

According to an updated Travel Health Advisory, there are now 34 destinations that may have circulating poliovirus.

As of May 3, 2024, the Global Polio Eradication Initiative confirmed various countries reported WPV1, cVDPV2, and cVDPV1 polio cases this year.

On April 26, 2024, the U.S. Centers for Disease Control and Prevention (CDC) reissued its Level 2 - Practice Enhanced Precautions notice regarding recent polio outbreaks.

The CDC says that adults who previously completed the full, routine polio vaccine series may receive a single, lifetime booster dose of polio vaccine before traveling to any destination listed. And to ensure that anyone who is unvaccinated or incompletely vaccinated completes the routine polio vaccine series before departing abroad.

In the U.S., polio vaccination services are generally available at health clinics and community pharmacies.

Previously, the World Health Organization (WHO) confirmed during the 38th meeting of the IHR Emergency Committee for Polio that the spread of the poliovirus remained a Public Health Emergency of International Concern and recommended its extension for a further three months to July 2024 to reduce the risk of the international spread of poliovirus.

Unfortunately, the U.S. is included in the WHO April 2024 notice.

US CDC Philippines 2024

Amidst the global measles outbreak of 2024, a new Health Alert has been issued for the Republic of the Philippines.

On May 2, 2024, the U.S. Embassy in Manila announced the U.S. Centers for Disease Control and Prevention (CDC) issued a Level 1 Travel Health Notice for Measles in the Philippines.

The CDC recommends that all travelers to the Philippines, including infants and pre-school-aged children, be fully vaccinated against measles.

If you are unsure whether you or your travel companions are fully protected against measles, schedule an appointment to visit a healthcare provider at least one month before traveling abroad so that you have enough time to be fully immunized, says the CDC.

If you don't think you can safely receive a measles-containing vaccine, talk to your doctor and consider making alternative travel plans.

In the U.S., measles vaccines are generally available at retail pharmacies.

Visit the CDC Travelers Health webpage for travelers to the Philippines to learn more.

As of late April 2024, the CDC listed 51 countries confronting measles cases this year.

This list includes Afghanistan, Angola, Armenia, Azerbaijan, Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Côte d'd'IvoireIvory Coast), Democratic Republic of the Congo, Djibouti, Equatorial Guinea, Ethiopia, Gabon, Ghana, India, Indonesia, Kazakhstan, Kyrgyzstan, Lebanon, Liberia, Libya, Malaysia, Mauritania, Nepal, Niger, Nigeria, Pakistan, Philippines, Qatar, Republic of South Sudan, Republic of the Congo, Romania, Russia, Senegal, Somalia, Sri Lanka, Sudan, Syria, Tajikistan, Timor-Leste (East Timor), Togo, Turkey, United Arab Emirates, Uzbekistan, Yemen, Zambia.

Moderna, Inc. today reported financial results and provided business updates for the first quarter of 2024.

On May 2, 2024, the Company reported $167 million in Spikevax® (COVID-19 vaccine) sales in the first quarter of 2024, compared to $1.9 billion in the same period in 2023, a decrease of 91%.

This sales decline aligns with the anticipated transition to a seasonal COVID-19 vaccine market.

"As we anticipate the launches of our Spikevax 2024-2025 formula and RSV vaccine, we are exercising financial discipline and have intensified our focus on building and utilizing AI technologies to further streamline operations and enhance productivity," said Stéphane Bancel, Chief Executive Officer of Moderna, in a press release.

"With ten late-stage programs and additional new programs advancing toward pivotal studies, we continue to expect numerous product milestones this year across our vaccines and therapeutics portfolio."

"This is the start of a banner year for our vaccine platform as we continue to advance mRNA medicines for patients. This is just the beginning."

A recent announcement of positive interim results from the NEXTCove Phase 3 trial showed that Moderna's next-generation COVID-19 vaccine (mRNA-1283) elicited a higher immune response against both the Omicron BA.4/BA.5 and original virus strains of SARS-CoV-2 compared to Moderna's licensed COVID-19 vaccine (mRNA-1273.222).

The next-generation vaccine is designed to be refrigerator-stable and paves the way for a combination vaccine against influenza and COVID-19 (mRNA-1083). The Company is engaging with regulators on the next steps.

And Moderna's Phase 3 trial of its combination vaccine against seasonal flu and COVID-19 (mRNA-1083) is fully enrolled. The Company anticipates data from the study in 2024.

The results from a literature search published on April 26, 2024, identified 16 study records that fit the inclusion criteria for reviewing the effectiveness of the JYNNEOS® (MVA-BN) vaccine against mpox.

Where the study population was exclusively or primarily those receiving pre-exposure prophylactic vaccination, JYNNEOS's adjusted vaccine effectiveness (VE) estimates ranged from 35% to 86% (n=8 studies) for one dose.

JYNNEOS's VE for two doses ranged from 66% to 90% (n=5) for two doses.

Where only post-exposure prophylactic vaccination was assessed, adjusted VE estimates were reported for one dose only at 78% and 89% (n=2). 

These researchers concluded that 'despite heterogeneity in study design, setting, and at-risk populations, the reported VE estimates against symptomatic mpox infection for one or two doses supports deployment of JYNNEOS for mpox outbreak control.

The U.S. Food and Drug Administration initially approved JYNNEOS for smallpox in September 2019 and extended its authorization for mpox in 2022. As of late 2023, about 1.2 million doses had been administered in 57 U.S. Jurisdictions.

As of May 2024, healthcare providers in the U.S. can order JYNNEOS through their preferred wholesaler and distribution partners to make it available for at-risk individuals at pharmacies.

According to a recent analysis, JYNNEOS booster (third) doses have not been recommended.

The World Health Organization recently published Mpox External Situation Report #32, which confirmed that from January 2022 through March 2024, a cumulative total of 95,226 mpox cases, including 185 deaths, were reported.

Note: Bavarian Nordic Inc., the owner of JYNNEOS, funded the research presented in this manuscript.
