I remember this rule fom school: we use yet in a negative or interrogative clause with meaning that something hasn't been done up to the present time.
According to cambridge dictionary it can be used to indicate action from now and for a particular period of time in the future, like in these examples:
She won't be back for a long time yet.
Our holiday isn't for weeks yet.
