Health and Saftety Protocols
We encourage you to monitor this page to stay abreast of the latest updates on health and safety protocols for THSNA 2022.


The safety of meeting attendees is THSNA's top priority, and we believe the most effective way to ensure the safety of all attendees is for them to be vaccinated against COVID-19. Please note that proof of vaccination will be required for all attendees.

Attendees should be aware that, while THSNA will make every effort to reduce the risk of COVID-19 transmission on site, it is possible that attendees will come in contact with people in airports, hotels, and around the hotel who could potentially carry the virus, which is why THSNA is requiring attendees to be fully vaccinated for their own safety, as well as the safety of others.

For the purposes of right of entry to the THSNA 2022, a person is considered fully vaccinated:

  • Two weeks after receiving the second dose in a two-dose series, such as the Pfizer and Moderna vaccines; or
  • Two weeks after receiving a single-dose vaccine, such as the Janssen (Johnson & Johnson) vaccine

Please note that booster shots will not be required but are strongly encouraged.

On-site Safety Measures 

Public health guidance on preventing the transmission of COVID-19 continues to evolve, and THSNA will base its on-site protocols on the latest guidance from the CDC in addition to local regulations in Chicago.


The wearing of protective masks is not required but is strongly encouraged of all attendees and THSNA staff.

International Attendees

International attendees should always check current travel restrictions to the U.S. on the Centers for Disease Control and Prevention (CDC) website, before planning your travel, to make sure you will be able to enter the U.S. In addition, please monitor local regulations at home to ensure that you will be able to return from the U.S.
