Need to Quarantine passport sticker

[ayesha_llk2]

So the officer stuck a green round sticker on my passport and mumblef something about Quarantine I didn't get. I should have asked clarification but I was tired out from the plane ride and forgot until later.

Does anyone know if the sticker color has any indication of need to Quarantine or not

Did you take both doses of an approved COVID-19 vaccine and wait out the 14-day period?
