A First in Human Study Investigating the Safety of an Unloaded and Loaded (With a Tetanus-containing Vaccine Booster) Microneedle Patch in Healthy Adults

The purpose of this research study is to check whether the MNS Miracus Patch (the study's investigational device, a small patch made up of microneedles that dissolve in the skin and can potentially deliver vaccines in a pain-free way) is safe to use and tolerated by humans when administered for 10 minutes, both as a plain patch (with no vaccine) and as a loaded patch (with the tetanus- containing vaccine included). This study will also investigate whether the patch delivers the correct dose of the vaccine in the loaded patches by checking the immune response of participants. As the device has not been tested clinically in humans before, this will be a first-in-human study involving healthy participants only, who have not previously received the full course of tetanus diphtheria vaccinations. This research study will take approximately 4-6 weeks of the participants' time. The study consists of a screening period up to 2 weeks to determine if participants are eligible for the study. Upon confirmation of eligibility, participants will enter the 'double-blind' study where they will receive one patch in clinic. Double-blind means that neither the participant nor the study doctor will know if the individual is receiving the empty or loaded patch. Participants will be randomly selected to receive the empty or loaded patch, and the number of participants will be equal in each group. During the study, participants will be asked to complete questionnaires, have photographs taken of their skin, give blood and urine samples and undergo general health checks including physical exam and vital signs. The clinical trial is funded by Microneedle Solutions Ltd. And Innovate UK, and will recruit 30 participants at one site in the UK only.

Maternal Immunization With Tetanus Toxoid, Reduced Diphtheria Toxoid, Reduced-dose (2 µg) Recombinant Pertussis Vaccine (TdaP2gen) and Its Effect on the Immune Response in Thai Infants up to 15-18 Months Old

Pertussis remains a major global public health problem. In Thailand, pertussis vaccination is recommended during pregnancy at 20-32 weeks' gestation, together with routine childhood diphtheria-tetanus-pertussis vaccination administered as a primary series at 2, 4, and 6 months and booster doses at 18 months and 4-6 years of age. TdaP2gen, a newly developed combined tetanus, diphtheria, and recombinant genetically detoxified acellular pertussis vaccine containing 2 µg pertussis antigen, has shown favorable safety and non-inferior immunogenicity compared with existing pertussis vaccines. However, data on its use in pregnant women, transplacental antibody transfer, and potential immune interference in infants remain limited. This study aims to evaluate the safety and immunogenicity of TdaP2gen in pregnant women, assess antibody transfer to newborns, and investigate immune responses to tetanus, diphtheria, and pertussis following primary and booster pertussis-containing vaccinations in infants and toddlers, including comparisons between whole-cell and acellular pertussis-containing vaccine schedules.

Risk Assessment of Community Spread of Multiple Endemic Infectious Diseases in a One Health Perspective

RACSMEI addresses the high burden of infectious diseases in low- and middle-income countries, including Cambodia, where limited surveillance and laboratory capacity often obscure etiologies and transmission dynamics. This knowledge gap hinders the design of effective prevention and control strategies. RACSMEI will improve understanding across multiple pathogens using a multidisciplinary One Health approach. We will answer key questions on burden, ecology, transmission and population immune status to inform targeted and culturally appropriate interventions. The project combines a nationally representative One Health survey, social-science methods, and multiplex, diverse diagnostics to efficiently test for 57 priority pathogens, including zoonotic and vector-borne agents, vaccine-preventable and elimination-targeted diseases, enteric, respiratory, and environmentally transmitted pathogens and selected neglected tropical diseases and parasites relevant to Cambodia. Mathematical modelling will reconstruct and forecast transmission dynamics and assess the potential impact of future public-health strategies. By integrating intersectoral data and innovative methods, RACSMEI will generate actionable evidence for public-health authorities, support precision One Health interventions, and help reduce disease burden in affected communities. The project also aims to ensure the transferability of methods and insights to other countries facing similar challenges.
