On May 18, 2021, the Oregon Health Authority (OHA) updated its mask guidance for fully vaccinated individuals, following CDC guidance issued the prior week. The new guidance includes two new documents – a new Statewide Reopening Guidance on Masks, Face Coverings, Face Shields and a document entitled Interim Guidance for Fully Vaccinated Individuals. The state also issued two new required signs (businesses should, but are not required to, post one or the other).
