The Green Pass is a digital or paper certificate that shows whether someone has received at least one COVID-19 vaccine dose.
It also shows if someone has tested negative or has recently recovered from the virus.

He said this after he and a number of other politicians and medical experts received threats on social media.
The government said that teachers will need a Green Pass when schools reopen this month after the summer holidays.
