Title : Association between COVID-19 vaccination and menstrual disturbances: A retrospective cohort analysis.


In the wake of the COVID-19 pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2), the global healthcare landscape has undergone a profound transformation. This transformation has been marked by the rapid development and deployment of COVID-19 vaccines by various pharmaceutical laboratories, including Pfizer-BioNTech, AstraZeneca, Sinovac, Johnson Pharm, and Moderna. While these vaccines have provided a ray of hope in the battle against the virus, they have also been accompanied by a spectrum of adverse reactions, ranging from common side effects like fever and headaches to more severe incidents such as anaphylaxis and myocarditis. However, amid the discussions surrounding these adverse reactions, there has been a lesser-explored topic - menstrual disturbances following COVID-19 vaccination. Despite being less documented in clinical trials, there have been reports of irregular menstruation, prolonged bleeding, intermenstrual bleeding, and menorrhagia in women after receiving the vaccine. To shed light on this intriguing phenomenon, a retrospective cohort study was conducted in Colombia, involving 139 women of reproductive age who reported experiencing menstrual alterations post-vaccination. The study's findings revealed a significant association between COVID-19 vaccination and menstrual disturbances, with amenorrhea and dysmenorrhea being the most frequently reported alterations. Additionally, as the number of vaccine doses increased, the prevalence of menstrual alterations also rose. This presentation delves into the multifaceted impact of COVID-19 on public health, the rapid development of vaccines, and the associated adverse reactions, with a particular focus on the intriguing and relatively understudied domain of menstrual disturbances following vaccination

  • Researchers attending the congress can use the presented information as a starting point for further investigation. The data on menstrual disturbances following COVID-19 vaccination, for instance, may inspire additional studies to better understand this phenomenon, leading to improved healthcare recommendations.
  • In essence, the research presented at the congress can act as a catalyst for further academic exploration, providing valuable insights into a relatively understudied area of vaccine-related health issues. It not only offers opportunities for expanding research agendas but also enriches the educational experiences of students by bringing real-world, contemporary health challenges into the classroom.
  • In summary, while the research may not provide a direct, ready-made solution to a specific design problem, it offers valuable information that can influence design decisions and approaches, promote adaptability and interdisciplinary collaboration, and underscore the importance of patient-centered and data-driven design. These indirect benefits can ultimately contribute to more efficient and effective design outcomes, especially in healthcare-related contexts.
