A groundbreaking study published today by the World Health Organization (WHO) in eBioMedicine has identified 17 endemic pathogens that frequently cause diseases globally, marking them as top priorities for new vaccine innovation. This comprehensive global analysis represents the very first systematic prioritization of endemic pathogens by the WHO, based on key criteria such as regional disease burden, the risk of antimicrobial resistance, and socioeconomic consequences for affected communities.
The study reaffirms crucial ongoing focuses in vaccine research and development (R&D), including significant diseases such as HIV, malaria, and tuberculosis, which together claim nearly 2.5 million lives annually. This stark statistic underscores the necessity for continued efforts to develop effective vaccines against these vital health threats.
Highlighting the urgent need for action, the report singles out pathogens like Group A streptococcus and Klebsiella pneumoniae as critical targets for disease control across all regions, revealing an escalating challenge posed by these pathogens’ growing resistance to existing antimicrobial treatments.
“Historical trends show that decisions regarding new vaccines have often been primarily influenced by financial returns rather than prioritizing lives that could be saved in vulnerable populations,” emphasized Dr. Kate O’Brien, Director of the Immunization, Vaccines and Biologicals Department at the WHO. “Our study offers a comprehensive view backed by regional data and expertise to evaluate vaccines that could not only significantly reduce the disease burden on communities today but also alleviate the medical expenses incurred by families and healthcare systems.”
To formulate this global priority list, WHO consulted with international and regional experts, seeking their insights on the most critical factors influencing vaccine introduction and utilization. The resulting analysis, which combined these insights with regional data specific to each pathogen, culminated in a ranked list of top 10 priority pathogens for each WHO region. These regional lists were then synthesized to produce the final global compilation of 17 endemic pathogens that require urgent vaccine research and development.
The newly established WHO global priority list of endemic pathogens for vaccine R&D aligns with the Immunization Agenda 2030, which aims to ensure equitable access to vaccines for individuals in all regions, protecting them from serious diseases. This list serves as a transparent framework to guide both regional and global agendas for new vaccine research and development, helping inform academics, funding bodies, manufacturers, and national governments on strategic directions for impactful vaccine innovation.
Additionally, this recent prioritization exercise for endemic pathogens complements the WHO R&D blueprint for epidemics, which aims to pinpoint pathogens with the potential to trigger future epidemics or pandemics, such as COVID-19 and severe acute respiratory syndrome (SARS).

They’ve released a new study in eBioMedicine that identifies 17 pathogens crying out for our attention like teenagers outside a kebab shop at 3 AM. Yes, you heard that right — 17! That’s more than some reality TV shows have contestants. Let’s dive into the delicious details, shall we?
A Serious Call for Action
The WHO’s new analysis is like a global wake-up call, prioritizing diseases that are not just poking us in the ribs but are actually causing a fair bit of mayhem in our communities. We’re talking about enduring nemeses like HIV, malaria, and tuberculosis, which continue to extinguish nearly 2.5 million lives each year. It’s enough to make you want to start a campaign for the world’s most effective mosquito repellent.
New Kids on the Block
But wait, it’s not just the usual suspects getting the nod. New entries like Group A streptococcus and Klebsiella pneumoniae have also made the leaderboard. They’ve been highlighted as major threats in every corner of the globe! Imagine being so notorious that you get recognized worldwide for the havoc you wreak. It’s practically the pathogen equivalent of a global bestseller! And with antimicrobial resistance on the rise, developing new vaccines isn’t just important—it’s critical!
Money vs. Lives: The Battle Continues
As Dr. Kate O’Brien from WHO pointed out, there’s often a misplaced emphasis on the monetary returns on new vaccine investments — when in reality, we should be focusing on saving lives in vulnerable communities. Yep, turns out that saving lives is a good PR move, WHO! Who would’ve thought? This new WHO list aims to overturn that idea with a focus backed by solid regional expertise and data. That’s right; *data* — the one thing every mate at a dinner party hates to hear about!
Pathogens on the Radar
Now, let’s unpack the WHO’s big reveal, shall we? Here are the rockstars of the list:
Pathogens Where Vaccine Research is Needed:
- Group A streptococcus
- Hepatitis C virus
- HIV-1
- Klebsiella pneumoniae
Pathogens Where Vaccines Need Further Development:
- Cytomegalovirus
- Influenza virus (yes, that old chestnut)
- Leishmania species
- Non-typhoidal Salmonella
- Norovirus
- Plasmodium falciparum (malaria)
- Shigella species
- Staphylococcus aureus
Pathogens Approaching Regulatory Approval:
- Dengue virus

Vaccines: A Global Agenda
But don’t worry, this isn’t just a grim list. The WHO’s global priority is to ensure that everyone, everywhere will benefit from vaccines that can save them from serious diseases. This isn’t just peas in a pod; this is the whole vegetable aisle! And it’s a clear road map for academics, funders, and manufacturers showing where their efforts can make the most impact. Who knew public health could have such a strategic visual?
Conclusion: A Call to Arms!
In conclusion, WHO’s new list highlights the urgent need for bolstering vaccine research and development in a way that could revolutionize health outcomes in low and middle-income countries. Anyone got a good fundraising idea? This could be great fodder for a telethon. Because how about we save some lives instead of just talking about saving the world at a few high-brow cocktail parties? It’s time to act on this list and turn the tide against these pesky pathogens once and for all!
