2023 Vaccination Policy

Having recently announced our upcoming ticket sales for Mosaic Experiment 2023: Celestial Chaos, you may be asking, “What is the Vaccination Policy for 2023?”

Update 6/14/23

In preparation for Mosaic Experiment 2023, we would like to announce the following suggestions to help prevent the spread of COVID at the 2023 event. We recognize that the Government has declared an end to the COVID crisis (4/4/23), however, as a community, we want to provide a safe event for all. Therefore, we will be suggesting the following:

  • If you have access to a test, please test before your arrival at Mosaic Experiment.

  • If you are ill, please practice civic responsibility and do not attend the event.

  • If your child is ill, they should not attend the event.

If you develop symptoms at the event, it will be requested that you take a test (we recommend bringing a test with you to the event). If you test positive, it is expected that you will leave the event.

We will be requiring all attendees to be fully vaccinated as defined by the CDC:

  • 2 weeks (14 days) since a person received one dose of an accepted single-dose-series COVID-19 vaccine (e.g., Janssen/J&J); OR

  • 2 weeks (14 days) since a person’s second dose in a 2-dose series of an accepted COVID-19 vaccine; OR

  • 2 weeks (14 days) since a person received the full series of an accepted COVID-19 vaccine (not placebo) in a clinical trial; OR

  • 2 weeks (14 days) since the person received 2 doses of any “mix-and-match” combination of accepted COVID-19 vaccines listed in Table 2 administered at least 17 days apart.


If you are not yet fully vaccinated, please use this guide below to help you plan:

  • Pfizer: 1st dose by August 16th, 2nd dose by September 13th

  • Moderna: 1st dose by August 9th, 2nd dose by September 13th

  • Johnson & Johnson: single dose by September 13th.

If you purchase a ticket and have not received your final dose by September 13th, 2023, you will not be admitted to the event and your ticket will not be refunded. 


What about boosters? Though we are not currently requiring booster shots in order to attend, we are highly recommending the newer bivalent booster, as it has been shown to significantly decrease risk of serious illness or hospitalization from the Delta and Omicron variants. If in doubt, get boosted!


Exemptions to being vaccinated: we will be making exceptions for children ages 0-5 due to the lack of an approved vaccine dose for that age bracket and their lower risk profile, as well as for those who qualify due to a valid medical reason as determined by the CDC: i.e., those who have had a severe allergic reaction after a first vaccine dose or have a known allergy to a component of the vaccine. If you fall into one of these exemptions, you MUST email us at gate@mosaicexperiment.com by September 14, 2023 to provide verification of this exemption.


Our wonderful Gate team will be checking your physical vaccine card or a screenshot of your digital vaccine record or a full photo of the card with all information clearly visible along with your ID when you arrive. If you are vaccinated but have misplaced your card, please contact your medical provider or the service location where you received your vaccine in order to obtain a replacement card or record as you will need this in order to attend! Please direct all questions you may have to gate@mosaicexperiment.com. 


We appreciate you doing your part by practicing the principle of Civic Responsibility and getting vaccinated to help ensure we have as safe a burn as reasonably possible when it comes to taking precautions against the spread of COVID-19 and its variants. If needs arise, we will be providing updates to this policy as we get closer to this year’s Mosaic Experiment. See you on the Razorgrass!
