ALIS'21 is a medical student congress organized by Acıbadem University medical students on September 4-5, 2021. Due to the pandemic conditions, the congress was held online and focused on the main theme of "Obstetrics & Gynecology." Originally planned for 2020 but postponed due to the sudden outbreak of the pandemic, this congress was the result of two years of hard work. The congress featured 10 expert speakers, whose presentations formed the core of the program. Participants were awarded through AIMS (Acıbadem University International Medical Student Research Awards) following oral and poster presentations. With 11 productive workshops that carried a multidisciplinary spirit, the congress became an unparalleled event, especially considering the circumstances of that period.
