Fanfest and Corona regulations in Iceland

Hi,

Fanfest will be held very soon and I´m planning on attending again. Though, with all the Corona topic still being a thing I wanted to ask if someone from CCP who works in Iceland could leave information if there are special rules and regulations regarding coming to Iceland during those times.
Are there special things I have to watch out and consider, or is everything alright as long as I can prove vaccination and are negative?

From Travel to and within Iceland:

This might still change before May, obvs.
