How do I know if I received a bivalent booster?

We recognize that it can be a little confusing to figure out which kind of vaccine you may have received, so we will be going off of the dates that the bivalent boosters became available. The requirements may differ depending on your country of residence.

For attendees in the United States:
  • If you completed an initial vaccine course (2-dose or single-dose), then you must have obtained a Moderna or Pfizer-BioNTech booster on or after September 1, 2022.
  • If you did not complete an initial vaccine course, you must have obtained a single Moderna or Pfizer-BioNTech vaccine dose on or after April 19, 2023.
For attendees in Canada:
In addition to an initial vaccine course, you must have received a booster on or after the following dates:
Booster Manufacturer Date
Moderna September 1, 2022
Pfizer-BioNTech October 7, 2022
If you received a vaccine course and/or booster outside of those two countries, please reach out to us ahead of time at covid@mysterium.net.
