Health & Safety Precautions

Health & Safety Precautions 

Our UC Davis team is eager to see you in-person at the UC Davis Conference Center this December, however the health and safety of attendees and staff is the number one concern.  We are closely monitoring the COVID-19 pandemic and recognize that this is a dynamic situation. We will continue to follow WHO, CDC, State and UC Davis guidelines for safely hosting events. We ask for your patience while we navigate these new paths, so that we can ensure attendees can come together again in-person safely.

While some states and countries are allowed to meet in-person with safety precautions in place, we understand that this is not the case across the globe. Therefore, the 2022 conference will be hosted as a robust and hybrid event to accommodate those who are unable to attend in-person.

In-Person Attendees

All in-person symposium attendees are expected to adhere to and abide by all safety precautions in place to protect against the spread of COVID-19. Our multi-layered safety approach includes prevention, protection, and mitigation components.

  • Prevention: Our Air Quality Research Center team has determined that proof of COVID-19 vaccination will be required for all registrants attending ASIC. Every in-person attendee, speaker, exhibitor, and all ASIC staff will be required to show proof that they are fully vaccinated with a vaccine approved for emergency use by the U.S. Food and Drug Administration or the World Health Organization before receiving registration badge and materials.
  • Protection: All attendees are required to wear a mask over their nose and mouth while indoors at all times except when actively eating or drinking. Presenters are required to wear a mask at the podium while giving a presentation or answering questions. Your safety and the safety of our staff is of priority and we thank you in advance for following these rules so that staff or security will not have to request you wear your masks.
  • Mitigation: We have a shared responsibility to help prevent the spread of COVID-19; therefore, we are asking each attendee to stay home from the conference if you are feeling unwell, or have felt unwell in the past 72 hours. Each day, attendees who are able to participate in-person will be asked to submit a short Daily Symptom Survey upon arrival at the UC Davis Conference Center designed by UC Davis to confirm their status. 

We are continuing to design more comprehensive guidelines to allow attendees to participate in a safe environment while networking and interacting with the other attendees. We will be relying on in-person attendees for personal accountability and self-compliance. We appreciate your assistance as we work together to curb the spread and keep all attendees healthy.

Thank you in advance for behaving in a manner that will keep all attendees safe.

How will you confirm vaccination?

We will have staff on-site that will check your vaccination record. You will be required to show proof of your vaccination through an electronic vaccination card, physical vaccination card, or a copy of your vaccination card. Our staff will match that record to your personal ID to ensure the names are the same and you will be admitted to receive your registration materials. 

Who needs to be vaccinated?

Everyone who attends ACM in-person will need to be fully vaccinated.

How do I become vaccinated?

You can find a clinic near you that will provide a vaccination by searching on

Unvaccinated Individuals

You can still participate in ACM as a virtual attendee.

Medical or Religious Exemptions for vaccination 

You can still participate in ACM as a virtual attendee.

Have Antibodies and Recovered from COVID 

The CDC strongly advises that all who have had COVID should also be vaccinated. Learn more about the risks of reinfection. In light of this evidence, ACM is requiring all attendees to be fully vaccinated by November 21, 2022 in order to attend the in-person meeting in Davis.

Otherwise, you can still participate in ACM as a virtual attendee.

Fully Vaccinated Definition 

By December 5, 2022 you must be 2 weeks post your final dose:

  • Second dose in a 2-dose series, such as with the Pfizer or Moderna vaccines, or
  • The one shot of a single-dose vaccine such as with Johnson & Johnson's Janssen vaccine
  • Or other vaccine dose recommendations as listed by the WHO

In most cases this means you will need your final vaccination dose by November 21, 2022.

What if I don't get vaccinated in time?

If you will not be fully vaccinated by November 21, 2022, you can attend as a virtual participant.
