A Study on the Self-Reported Physician-Diagnosed Cardiac Complications Post mRNA Vaccination in Saudi Arabia

Introduction The advent of mRNA-based vaccines has been a pivotal milestone in the global response to the pandemic, prompting widespread vaccination campaigns, including in Saudi Arabia. This study investigates self-reported physician-diagnosed cardiac complications post mRNA vaccination in Saudi Arabia, recognizing the need to monitor these rare events. The research aimed to study the self-reported physician-diagnosed incidence, nature, and associated factors of cardiac complications in this distinctive demographic group of post-mRNA vaccinations. Due to the scarcity of specific vaccine safety data, the study sought to provide data supporting public awareness and recommendations for global public health practices. Emphasizing ethical considerations, the study focuses on local factors, contributing valuable insights into the safety profile of mRNA vaccines, and aiding informed decision-making for public health strategies in Saudi Arabia and globally. Material and methods In a cross-sectional design, the study employs a culturally adapted questionnaire covering demographic details, vaccination history, health conditions, and perceptions. A rigorous development and validation process ensured the reliability of the questionnaire. A sample size of 804 participants was collected through an online survey link distributed via social media through the groups. Statistical analyses explored associations between demographic variables, vaccination behaviors, health diagnoses, and perceptions using IBM SPSS version 23 and Microsoft Excel. Results Significant associations were found among demographic variables, vaccination behaviors, health diagnoses, and perceptions of self-reported physician-diagnosed cardiac complications post mRNA vaccination in Saudi Arabia. Key findings included a high mRNA vaccine uptake with a frequency of 747 (92.79%) and a mere frequency of 218 (27.11%) reporting cardiac complications post vaccination. The study highlighted diverse influences on vaccine decisions, with a frequency of 384 (47.76%) expressing neutral confidence in vaccine safety. The study contributes to the global understanding of mRNA vaccine safety, emphasizing the unique Saudi demographic context. Methodological rigor, ethical considerations, and acknowledgment of limitations enhance credibility. Collaborative efforts and tailored recommendations for public health policies and communication strategies are underscored. Conclusion This study on self-reported physician-diagnose
