Other Pathogens with Epidemic Potential

ISIDORe preparedness action

Will the next global infectious threat be an orthopoxvirus, or an enterovirus? Will it be even caused by a known pathogen? Can we be ready for the next pathogen X?

The ISIDORe consortium supports scientists with an interest in epidemic-prone pathogens, including pathogen X.

Researchers are invited to submit any proposal that:

  • Can be advanced by access to at least one of our services,
  • Falls under one of the following sections (see SCOPE), and
  • Is focused on pathogen X or at least one of the three pathogen classes specifically identified below.


Access to In vivo models will only be granted to applicants with projects demonstrating sufficient justification (including in vitro evidence and choice of model) for using animals for scientific purposes.

For access to Regulatory advice services, please select the Section closest to your countermeasure of interest.

Services such as Access to clinical samples and Access to clinical trials are not available for this call.

Please consult our full service offer here.


Your proposal must align with at least one of the Sections below:

Section 1: Surveillance & epidemic management
Section 2: Natural history of infectious diseases / Deciphering & understanding pathogens’ biology, host-pathogen interactions and host responses to infection
Section 3: Diagnostics
Section 4: Therapeutics
Section 5: Vaccines
Section 6: Social sciences & epidemiology
Section 7: Vector biology & vector control (if applicable)


Your proposal must focus on at least one of the following pathogens (to see the full list of ISIDORe PPPs, follow this link):

ISIDORe PPPsComments and/or limitations
Pathogen XCausative 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). Any plausible candidate would be eligible, given coherent justification. Proposals focused on the development of preparedness tools (flexible diagnostic method, “universal” vaccine platform, etc.) are eligible under Pathogen X.
Non polio enterovirusesNone
Polio enterovirusesNone
