ACS Spring 2023 Vaccine Requirements 

Safety is a core value of the American Chemical Society and will continue to be our ultimate guide for actions affecting ACS members, staff, meeting attendees, and other stakeholders. Given the decrease in the severity of the pandemic and because the CDC has loosened its restrictions relative to COVID-19, starting January 1, 2023, ACS will no longer require attendees to show proof of a COVID-19 vaccination for events. We do, however, strongly encourage attendees to take their health and well-being (and that of their fellow attendees) seriously when attending ACS events. We encourage you to follow all the appropriate health-related guidance for you as an individual. If you are experiencing any COVID-19, flu-like, or other viral symptoms or are feeling sick, please do not attend an ACS event and take advantage of any hybrid or virtual programming that might be available. We reserve the right to change this guidance at any point for any ACS-sponsored event.
