What will be the attendance options for APHA 2021?

APHA 2021 will be a mix of in-person and virtual sessions and events held in Denver and online. While many people are eager to travel and connect to their peers in person, we understand that many people are uncomfortable or unable to travel. They will have the option to attend virtually and still experience the Annual Meeting and Expo.

What safety precautions are you taking for in-person attendees?

APHA recognizes the need to provide APHA 2021 attendees with the safest experience possible.

Based on the latest CDC recommendations and in line with guidelines from local authorities in Denver:

  • All in-person Annual Meeting attendees and contractors must be fully vaccinated to participate. Full vaccination is defined as two shots of the Pfizer or Moderna COVID vaccine and one shot of the Johnson & Johnson product (or a comparably approved vaccine if you are an international attendee).
  • Facial mask wearing is required for all indoor activities at the Annual Meeting.

We also encourage all attendees to get their annual flu vaccine before attending.

It can take up to six weeks to complete the full schedule for COVID vaccines that require two doses to achieve full efficacy and 14 days for the influenza vaccine. So please plan accordingly. For those traveling from overseas, please be aware of restrictions placed on your country of origin, as travelers from some countries are required to quarantine for two weeks.

We will provide appropriate physical distancing in meeting rooms and hand sanitizer throughout the meeting venue.

For more, read our Annual Meeting Infection Control update and our Annual Meeting participation policies.

How do in-person attendees verify their COVID-19 vaccination status?

Your vaccination status will be verified on-site prior to admittance to in-person Annual Meeting activities.

  • Bring your electronic (via the CLEAR app) or official CDC vaccination card (a copy or photo of the card is acceptable) and government-issued ID to prove you are vaccinated.
  • If you are using the CLEAR app, you just need to set up a Digital Vaccine Card, not the full Health Pass.
  • Upon arrival at the Colorado Convention Center, attendees will go through a checkpoint to show their vaccination status and receive an identification sticker for their meeting badge. This sticker must be on your badge to access meeting activities.
What if I want to switch my registration from in-person to virtual, or from virtual to in-person?

You can change your registration status by sending a request via email to Please include your registration number, which can be found at the top of your registration confirmation.

No refund will be given for switching to virtual. If switching to in-person, you will be required to pay the difference between the cost of a virtual registration and an in-person registration.

Why aren't all Denver sessions available for live online viewing?

Cost restrictions prohibit APHA from livestreaming all content from Denver. By providing recordings of in-person sessions only, we are able to reduce the cost for the virtual audience, allowing more people to participate than ever before. The virtual audience will still have live and on-demand access to more than 300 virtual sessions plus the recordings of all Denver presentations.

When will the online program be available?

The online program is now available at

Will presenters be required to register for the in-person or the virtual meeting?

All presenters must be members of APHA and registered for the Annual Meeting. In-person presenters must be registered for the in-person meeting. Virtual presenters may register for the virtual meeting or the in-person meeting. Virtual presenters can present from Denver using their own laptop.

What time zones will be used?

The schedules for both the in-person and virtual meeting will refer to Mountain Time as the in-person meeting takes place in Denver.

Why are roundtable sessions only being offered virtually?

All roundtables sessions will be done virtually due to concerns around physical distancing. A typical roundtable session allows up to 10 participants at a table. Going virtual allows more attendees to interact with the presenters. We have taken your feedback from last year's virtual roundtables and are working to improve the experience.

Why are poster sessions only being offered virtually?
Last year, we received an overwhelming, positive response about virtual poster sessions. We learned that presenters liked this option because they were able to create a fine-tuned presentation ahead of time. This year, we are dedicating two days to poster presentations and are adding a live component.
As a virtual attendee, will I be able to ask questions or participate in discussions?

Yes, the virtual audience will be able to ask questions at virtual sessions and at the limited livestreamed sessions.

Will sessions be recorded for on-demand viewing?

Poster sessions and roundtable presentations will be pre-recorded. Virtual oral sessions are being recorded and will be available for on-demand viewing. In-person oral sessions are being recorded in Denver and will be available for on-demand viewing only. All content will be available for three months following APHA 2021.

When should I travel to Denver?
