Enhanced Participation

As part of the enhanced 2022 SOT meeting experience, registrants who are fully vaccinated against COVID-19 can attend Scientific Sessions in person in San Diego, and all registrants can watch most of them remotely through livestreams. Individuals on-site and remote also will be able to engage in live question-and-answer discussions during most sessions. In addition, all streamed sessions will be viewable on demand for all registrants upon a session’s conclusion.

Registration Confirmation and Badge Pickup

You should receive a registration confirmation via email, whether you register directly online or send your Registration Form to the SOT Registration Department via email, mail, or fax. If you don’t receive your confirmation within two weeks, please contact SOT Headquarters or call 703.438.3115.

Per California regulations, proof of full vaccination against COVID-19 is required for all on-site attendees to ensure the safety and health of all participants. To facilitate the confirmation of proof of vaccination, all badges will be picked up on-site in San Diego. Details on how vaccination proof or medical exemption documentation will be collected and reviewed will be communicated before the meeting.

Because all registrants will pick up their badges and event tickets on-site, please allow extra time upon arriving at the San Diego Convention Center to acquire your badge before your first planned activity.
