RESEARCH SCOPE AND PRIORITY PATHOGENS
ISIDORe preparedness actions: anticipation avoids escalation
To try to avert future pandemics, and advance the development of the appropriate countermeasures, the ISIDORe project proposes calls for proposals to support research on the pathogens with epidemic potential from the list of ISIDORe Priority Preparedness Pathogens (PPPs).
- Diagnostics
- Surveillance and epidemic management
- Vector biology and vector control
- Natural history of infectious diseases / Deciphering & understanding pathogens’ biology, host-pathogen interactions and host responses to infection
- Therapeutics
- Vaccines
Proposals focusing on research that would improve preparedness to a range of pathogens are especially encouraged.
For example:
- Development of multi-pathogen and/or flexible diagnostic strategies
- Development of broad-spectrum antiviral therapeutics
- Development of versatile vaccine platforms

Priority Pathogens
Limitations apply to pathogens marked with a * – please see the dedicated subsection below
RG4 PATHOGENS
Ebola virus*

Marburg virus
This refers to all members of the Marburg marburgvirus species.
Nipah virus
This refers to all members of the Nipah henipavirus species.
Hendra virus
This refers to all members of the Hendra henipavirus species.
Lassa virus
This refers to all members of the Lassa mammarenavirus species.
New World arenaviruses
This refers to species within the Mammarenavirus genus which cause viral haemorrhagic fevers, including but not necessarily limited to the members of the Guanarito, Junin, Lujo, Brazilian, Chapare and Machupo mammarenavirus species.
CCHF virus
This refers to all members of the Crimean Congo haemorrhagic fever orthonairovirus species.
RESPIRATORY PATHOGENS
Zoonotic betacoronaviruses
This refers to all members of the subgenera and species of the Betacoronavirus genus, known to cause human disease, or with a potential to, including, but not necessarily limited to, the Sarbecovirus subgenus and Severe acute respiratory syndrome (SARS)-related coronavirus species as well as the Merbecovirus subgenus and Middle East respiratory syndrome (MERS)-related coronavirus species.
Influenza A
This refers to all the members of the Alphainfluenzavirus influenzae species. The members of the Beta-, Delta– and Gammainfluenzavirus species are eligible for support in projects proposing pan-influenza approaches applicable to Influenza A.
Y. pestis*
This refers to all members of the Yersinia pestis species. The focus for ISIDORe’s scientific programme is pneumonic plague.
M. tuberculosis / bovis*
This refers to all members of the Mycobacterium tuberculosis and Mycobacterium bovis species.
C. burnetii
This refers to all members of the Coxiella burnetii species.
VECTOR-BORNE PATHOGENS & THEIR VECTORS
Rift valley fever virus
This refers to all members of the Rift valley fever phlebovirus species.
Zika virus
This refers to all members of the Zika virus species.
Chikungunya virus
This refers to all members of the Chikungunya virus species.
West Nile virus
This refers to all members of the West Nile virus species.
Dengue virus*
This refers to all members of the Dengue virus species.
Japanese encephalitis virus*
This refers to all members of the Japanese encephalitis virus species.
Yellow fever virus*
This refers to all members of the Yellow fever virus species.
Tick-borne encephalitis virus
This refers to all members of the Tick-borne encephalitis virus species.
Plasmodium*
This refers to all members of the species known to cause malaria in humans: Plasmodium i) falciparum, ii) vivax, iii) malariae, iv) ovale curtisi, v) ovale wallikeri and vi) knowlesi.
B. burgdorferi*
This refers to all members of the Borellia burgdorferi species.
OTHER PATHOGENS WITH EPIDEMIC OR PANDEMIC POTENTIAL
Pathogen X
This refers to the causative agent of Disease X that “represents the knowledge that a serious international epidemic could be caused by a pathogen currently unknown to cause human disease” (WHO). Please note that here, we are targeting projects proposing universal solutions to infectious threats (e.g., “universal” vaccine platforms, highly flexible diagnostic tests, etc.). Applicants are not expected to identify certain know pathogens as potential future Pathogens X.
Orthopoxviruses
This refers to all members of the Orthopoxvirus genus known to cause human disease, or with a potential to, including but not necessarily limited to the Variola virus and Monkeypox virus species.
Non polio enteroviruses
This refers to all members of the species within the Enterovirus genus (except those listed below) and known to cause non polio human disease, or with a potential to.
Polio enteroviruses
This refers to the serotypes (1, 2 & 3) within the Enterovirus C species known to cause polio in humans.
limitations
Limitations on some topics apply, due to the existence of countermeasures, as well as current dedicated funding channels or support programmes, for some of the ISIDORe PPPs.
