Comparability Trial of the MVA-BN Vaccine Manufactured in Different Production Cells

Randomized, double-blind, phase 2b trial to assess comparability in immunogenicity, safety, and reactogenicity of MVA-BN vaccine manufactured in primary chicken embryo fibroblast (CEF) cells and the CCX.E10 quail cell line in adults

Prospective Follow-up After MVA-BN Booster Vaccination

POQS-Boosted is a prospective observational study during which individuals who received Booster vaccination against mpox with the MVA-BN vaccine will be invited to provide biological samples at multiple times over the course of two years.

Evaluate the Safety and Immunogenicity of the MVA-SIBP Vaccine in the Democratic Republic of the Congo

To evaluate the safety and immunogenicity of the MVA-SIBP vaccine using a double-blind, randomized, controlled, age de-escalation design conducted in Kinshasa, Democratic Republic of the Congo (DRC).

Open-label, Multicenter Immunogenicity and Safety Study of MVA-BN Vaccine in Children From 2 Years to Less Than 12 Years of Age Compared to Adults for the Prevention of Smallpox, Mpox, and Related Orthopoxvirus Infections

All participants will receive 2 vaccinations of the same dose of Modified Vaccinia Ankara Virus (MVA-BN) vaccine 4 weeks apart (standard regimen). Serum samples for assessment of immune response will be collected at baseline (visit of first vaccination) and at 2 weeks (week 6), 6 months (week 30), and 1 year after the second (last) vaccination.

Epidemiological and Clinical Characteristics of Human Mpox Outbreak in Equateur Province in the Democratic Republic of Congo (Part2)

The goal of this observational study is * to better understand the dominant modes of transmission * to estimate the extent of transmission among contacts by determining the secondary infection rate for human-to-human transmission at an individual level and identifying factors associated with secondary infections. * to determine the proportion of asymptomatic or pauci-symptomatic infections. * to characterize the incubation period of mpox and the duration of infectiousness, including reproduction numbers. * to assess serological responses following confirmed infection.

Epidemiological and Pathophysiological Insights Through a Cross-sectional Survey (EPIC)

This study aims to better understand how mpox is spreading in the DRC, how it affects different groups of people, and how well vaccines protect against it. The study is designed as a cross-sectional survey, meaning researchers will collect and analyze data from patients diagnosed with mpox at a single point in time. It will also use a case-control approach, comparing people who test positive for the virus to those who test negative, to identify risk factors and evaluate the effectiveness of the vaccine.
