The 65th American Society of Hematology Annual Meeting and Exposition, a premier event in classical and malignant hematology, takes place Dec. 9-12 in San Diego, California, and online. Registration is open for members, non-members, groups, exhibitors, and media. The ASH event features more than 7,000 accepted abstracts representing cutting-edge science in hematology. International travelers attending the meeting in person should be aware that citizens of some foreign countries may require a visa to enter the United States. However, there is a virtual option available during the registration process, allowing attendees to experience the latest breakthroughs in hematology through real-time session broadcasts, access to on-demand recordings, and interaction with speakers.
