I have a venom token on my animals card on slot 1. Does it disappear If I play the sponsor quarantine lab or does it just work for the effects that are triggered after the card is played ?

It only prevents future effects from affecting you.

It only stops you from gaining new tokens: https://boardgamegeek.com/thread/282442 ... 3#39953553

If you were vaccinated after already being sick, it's too late to prevent the illness.
