As above, lambivac is a vaccination to prevent clostridial disease and dose is 2ml for sheep or goats (though it is recommended to dogoat boosters every 6 months instead of once a year) and there is zero milk and meat withdrawal.
Worming is a different story entirely, I would recommend speaking to your vet who can discuss when, if and how to worm your goats, often based on checking faecal samples for worm eggs to make sure they need worming.
Wormer will need dosing to weight and can be a different dose to sheep depending on type of wormer so do quiz your vet and weigh, or measure girth and length and follow the formulas for estimating goat weight online, to make sure it is correct. Depending if they need worming, different wormers have different withdrawal periods so again, check with your vet.
