ok as a farmer i never really dealt with goats but i looked this up for you and found this site its very useful and interesting and should provide you with a fair amount of knowledge 
http://www.allgoats.com/health.htm 
also this is from that web page but if your really unsure call your vet and ask on the phone they should help if they vallue your custom in future should you need to call them however may i recommend going to a short course ok goat keeping it'll save you a lot on vet bills if you do most things yourself .
GOAT VACCINATION PROGRAMME FOR THE PROTECTION AGAINST CLOSTRIDIAL
DISEASES AND TETANUS
 DOSE
 
Primary Course 2 doses 4 – 6 weeks apart 2ml 
Booster Every 6 months 2ml 
Kids from vaccinated does Start at 10 – 12 weeks of age 2ml 
Kids from unvaccinated does Start at 2 – 4 weeks of age 2ml 
Pregnant does  Booster 2-4 weeks before kidding 2ml 
this is just what i found and by no means is me telling you this is absolutely correct as things to do with livestock are always changing. best thing is buy the wormer and read the instructions first . hope this helps
