2022 SIOP Annual Conference

Health and Safety

We look forward to welcoming SIOP conference attendees to Seattle!

We continue to keep health and safety considerations top of mind, monitoring and adjusting plans according to Centers for Disease Control and Prevention and World Health Organization recommendations, governmental, public health, and venue regulations and recommendations as they pertain to COVID-19.

Please note that all in-person registrants, by the nature of their participation in the meeting in Seattle, agree to the health and safety waiver and assumption of risk.


COVID-19 Precautions for In-Person Conference Attendees

UPDATE:  APRIL 6, 2022


SIOP is partnering with 42Chat, an intuitive digital platform, for managing the secure collection of vaccination and testing information. This service will communicate directly with in-person registrants via text message—no need to download an app or create a login. When a registrant successfully uploads their documentation, the service will provide them with credentials to access to the conference activities. In-person registrants will receive an email with more information about connecting with this platform. See below for details vaccination and negative test requirements.


To encourage self-monitoring of symptoms while onsite, conference participants will receive a health screening questionnaire each morning (April 27-30) via text message from 42Chat, the platform described in the prior section. Completing and “passing” the screening will be a requirement for earning access to the conference activities each day, in addition to the vaccination or testing requirement.


There is a testing facility available in the convention center and others in the local area. Attendees choosing the negative testing method of verification need to plan ahead to ensure they understand the requirements and the necessary timing of tests.


Unless otherwise required by the venue, SIOP will follow the CDC “Community Levels” guidance for masking. Use the CDC’s search tool to find the level in King County, Washington, where Seattle is located, and follow the guidance provided. Masks are welcome.


SIOP is introducing a color-coding system for the badge lanyards this year, in which different color lanyards will indicate each attendee’s comfort level. Signage at registration will describe the colors, but please also recall that not all attendees can perceive color, so having patience and grace with each other will go a long way towards helping us all have a positive SIOP Annual Conference experience.

For more information, please see the health and safety information provided by the Washington State Convention Center (soon-to-be renamed the Seattle Convention Center) at https://wscc.com/safetyfirst.


What to Know about the “Vaccine or Test” Requirement for the 2022 SIOP Annual Conference


  What vaccine types are acceptable?

Fully vaccinated is defined as an individual who has received all the required doses of an FDA authorized COVID-19 vaccine (two doses of the Moderna or Pfizer-BioNTech vaccines, or one dose of the Johnson & Johnson vaccine) or a WHO-authorized COVID-19 vaccine series, AND 14 days have passed since the final dose.


  What types of COVID-19 tests are acceptable?

A negative FDA-authorized or approved molecular (e.g., PCR) test, or an FDA authorized or approved antigen (e.g., rapid) test administered within the previous 72 hours by a testing agent, including a laboratory, health care provider, or pharmacy. Self-administered tests or at-home kits are not accepted.


Note that PCR tests may take 2-3 days for lab processing, so please plan ahead so test results are available on the first day of the event. You will also need to retest while in Seattle if you plan to attend more than one day (given the “administered within 72 hours” requirement.)


Planning Ahead

It will take all of us in the SIOP community working together to protect the health and safety of all who are participating in the SIOP Annual Conference. For questions about COVID protocols, please contact healthandsafety@siop.org.


Previous Health & Safety Updates

UPDATE: March 12, 2022


Effective March 12, the State of Washington has lifted its mask mandate, with King County (where Seattle is located) and the Washington State Convention Center following suit.

As such, SIOP plans to follow the CDC’s new "Community Levels” guidance regarding masking.

Currently, King County is in the “Low” level, meaning that wearing a mask will be optional during the SIOP Annual Conference.

Please note that this decision is subject to change, and that SIOP reserves the right to reinstitute a masking policy for our Annual Conference at any point until and throughout the conference dates. Please also note that attendees are welcome to wear masks and that disposable masks will be available at the registration desk for attendees those find themselves in need of one.


SIOP will continue to require proof of Covid-19 vaccination or a negative test to participate in-person at the conference in Seattle. Details about this requirement follow.

Please note that early next month, we will reevaluate the testing requirement. There are not plans to eliminate it, rather, we will assess the pandemic conditions and event logistics and determine whether to permit alternate types of testing that may be more convenient to source both pre-event and onsite than what is currently required.

UPDATE: February 28, 2022

The state of Washington will be lifting its mask mandate on March 12, per an announcement from Governor Jay Inslee. We will monitor the impact of this decision on King County, WA, the City of Seattle, WA, and the Washington State Convention Center and provide an update on masking conditions at the SIOP Annual Conference when we are able.

UPDATE: February 16, 2022

We received notification from our meeting venues in Seattle that the local public health order requiring vaccination verification or testing for indoor establishments will no longer be in place effective March 1, 2022 (read more here and here).

King County, where Seattle is located, has indicated that the basis for their decision to end the requirement includes the facts that 80% of King County residents are fully vaccinated, and that COVID-19 infections and hospitalizations in King County are dropping.

We are celebrating this good news out of Seattle, while also recognizing that our conference will bring in attendees from many places, including from regions where vaccination rates are low and infection and hospitalization numbers are not as encouraging.

As such, SIOP currently plans to continue a “vaccination or test” requirement for our conference in April. The specifics may be adjusted as pandemic conditions change in the coming weeks (e.g., the testing could be updated to accept self-administered tests), but current and prospective registrants for the in-person SIOP Annual Conference in Seattle should still anticipate a “vaccination or test” requirement for our event.
