Actually the advice from the Goat Veterinary Society is to use Lambivac for the clostridial diseases and a separate pasteurella (Ovipast) vaccine. So initially 2 doses 2ml each of Lambivac 4 - 6 weeks apart, and about a week into the 4 weeks give a separate 2ml dose of Ovipast, and then again repeat 4 weeks later. That way the goat doesn't get a huge whoosh of vaccines all in one go. Lambivac has to be boostered every 6 months, Ovipast (I think) once a year. Advice re Ovipast is to make sure the animal is not stressed, so I wouldn't give it a newly arrived goat until they settled in well and trust you and you are able to do it quickly and without fuss. Even more important if they are in kid. (Mine get all the injections when on the milking stand and while tucking into some grub - usually they don't notice...., except sometimes when it's into the muscle)
I don't know when your goat is due to kid, but if she hasn't had any clostridial vaccinations so far (or if you are not sure she has) you should do the initial double course and hopefully time it so that the second dose is just given 2 to 3 weeks before she kids. Vaccines are injected under the skin only.
I would also do a FEC count for both worms and fluke, and treat if necessary accordingly.
