newbie question. After worming, are the eggs safe to eat afterwards?

Wazine is the only medication currently approved for poultry deworming. It is NOT approved for egglayers, however. There is NO medication approved for egglayers. So you would be going off-label to deworm your layers.
On BYC most posts that I have read mention tossing eggs for a couple of weeks after wormers. Of course it is always best to talk with your veterinarian and get a prescription. They sell the wormers without a prescription, however, and there are numerous threads on valbazen (albendazole), safeguard (fenbendazole) and wazine. Other wormers too, like ivermectin.
If you sell eggs or meat, this could be an issue for you, as food safety is a legal issue.
Wazine only kills large roundworms and thus if your chickens have other types of worms they can die from a worm infestation even after giving Wazine.
I have read on BYC one account of how the advice was given (I think from a county extension office or someplace like that) to destroy the flock for a worm infestation (egglayers) since *I believe* as community poultry specialists legally that is all they can recommend (unless they are vets). But as backyard pet flock owners of course we make our own decisions. Just be sure to research it carefully and be aware that the pharmaceutical companies don't have the monetary incentive to do the research necessary to claim how many days to toss eggs.
Additionally, it is important to recognize that if we constantly give the same wormer (without rotation of wormers) to our poultry, we are likely creating resistant worms.
It is your food supply, or your pets we are talking about, and thus making an informed decision is vital unless going to the vet (which not all of us can afford).
Addendum: Some vets will do a fecal float test for worms for a small fee (false negatives are possible). This may be a good option for some folks, as worming medications are hard on chickens and can even kill a sickly chicken.
