Marburg

Priority List of Adverse Events of Special Interest for

Marburg Virus

Version 1.1 (Updated 02 October 2024)

The SPEAC Executive Board welcomes input on this AESI list and will update it periodically. Please share input with the SPEAC and Brighton Collaboration team at bc-coordinator@taskforce.org.

This list of potential Adverse Events of Special Interest (AESI) that could follow vaccines to prevent Marburg Virus Disease (MVD) was developed based on criteria established by the Safety Platform for Emergency Vaccines (SPEAC), which include:  
  1. A known association with immunization or a specific vaccine platform. 
  2. The occurrence during wild-type disease due to viral replication and/or immunopathogenesis. 
  3. A theoretical association derived from animal models.  
Special populations, including pregnant women, children, adolescents, and immunosuppressed individuals, may experience an increased frequency and severity of any of the AESIs listed as relevant to all populations. There are also specific AESI that are of particular relevance to special populations, and these are listed according to the population. It is important to note that children, pregnant women and immunocompromised individuals may also have increased severity of expected local and systemic reactogenicity, as well as unexpected autoimmune conditions.  

Note: Several AESI highlighted in gray are included due to their presence in MVD itself but are only relevant for possible live-attenuated vaccines (e.g. live attenuated MARV, measles vector, etc). These are not recommended to include for all platforms, e.g. Adenovirus-vectored vaccines.  

This list is based on available data for MVD vaccines, for consideration in deployment of investigational MVD vaccines in response to the 2024 outbreak in Rwanda.  Adaptions may be needed depending on the application.

Priority List of Adverse events of special interest for

Mpox

Version 1.0 (Updated 17 September 2024)
Likely due to direct viral infection and relevant mostly to live-attenuated vaccines.
Recommend applying FDA 2007 Toxicity Grading Scales: https://www.fda.gov/regulatory-information/search-fda-guidance-documents/toxicity-grading-scale-healthy-adult-and-adolescent-volunteers-enrolled-preventive-vaccine-clinical#:~:text=Toxicity%20Grading%20Scale%20for%20Healthy%20Adult%20and%20Adolescent
§ Late sequela of MVD with evidence of viral persistence in tissue.
Hemorrhagic disease should have clinical evidence of spontaneous bleeding

** Evidence of spontaneous bleeding would suggest hemorrhagic disease. Evidence of spontaneous bleeding includes ≥ 1 of: bruising, purpura, epistaxis, petechiae, hematuria, hematemesis, hematoma, hematochezia, persistent bleeding from venipuncture sites, hemorrhagic oozing of skin lesion, conjunctival bleeding, vaginal bleeding (unless menstruating), occult bleeding from rectum, intracranial bleeding. These are included in the CD for thrombocytopenia; and the Companion Guide for thrombocytopenia has a glossary of terms relevant to spontaneous bleeding.
†† Organ involvement may present individually; severe infection would result in multisystem involvement.
§§ Theoretical concern about enhanced disease due to binding Abs to MARV antigens.
¶¶ One case report (Johannesburg ex Zimbabwe: Gear JSS, BMJ 1975 ); and evidence in Ebola virus disease.

*** Guidelines for data collection exists as part of the GAIA project: https://brightoncollaboration.org/global-alignment-of-immunization-safety-assessment-in-pregnancy-gaia/
 The Stillbirth CD publication update is pending.
§§§ BC CD for hypertensive disorder of pregnancy
¶¶¶ Age-based risk for children aged ≤ 5 y.

**** BC tools exist for Generalized convulsive seizure and Fever.
