Health & Safety Guidelines at ACS Summer School

Updated February 2, 2022

Mask & COVID Vaccination Requirements

The ACS Summer School on Green Chemistry & Sustainable Energy will be a mask and vaccination required event for ALL students, instructors, and ACS staff who plan to attend. All individuals will need to be fully vaccinated by July 1, 2022, 14 days from the start of the event. Acceptable proof of vaccination will be required. All attendees are expected to fully comply with all health and safety guidelines. Failure to adhere to the requirements could lead to removal from the venue or other disciplinary action.

In light of events surrounding COVID-19, this is an appropriate time to remind ourselves of the risks incident to participating in the Summer School. Even with every reasonable precaution to keep you safe as outlined for you by the CDC, ACS cannot fully eliminate all risks of harm to attendees or guarantee their safety, especially from risks posed by COVID-19 or its variant strains. Ultimately, you are responsible for your own safety.

Updates regarding health and safety protocols will be made as more information becomes available.

  • Will vaccinations be required to attend ACS Summer School on Green Chemistry & Sustainable Energy in-person?

    Yes, full vaccination will be required for all students, instructors, and staff who seek to gain access to the in-person event in Golden, CO.

  • What is considered full vaccination? Which vaccinations will be accepted?

    According to the Centers for Disease Control (CDC), people are considered fully vaccinated for COVID-19 two weeks after they have received the second dose in a two-dose series (e.g., Pfizer/BioNTech or Moderna), or two weeks after they have received a single-dose vaccine (e.g., Johnson & Johnson’s/Janssen).

    Vaccination guidance applies to COVID-19 vaccines authorized for use and for emergency use by the U.S. Food and Drug Administration (i.e., Pfizer-BioNTech, Moderna, and Johnson and Johnson (J&J)/Janssen COVID-19 vaccines), and COVID-19 vaccines authorized for emergency use by the World Health Organization (WHO) (i.e. Pfizer-BioNTech, Moderna, and Johnson and Johnson (J&J)/Janssen, Oxford/AstraZeneca, Covishield, Covaxin, Sinopharm/BBIBP-CorV, and Sinovac/CoronaVac), on or before February 15, 2022.
