OK, I have to modify that advice somewhat. I came across this: http://www.goatworld.com/articles/enterotoxemia/enterotoxemia3.shtml >But any older animal that has not had its yearly boosters is at risk, as is a >yearling that did not receive at >least 2 vaccinations no earlier than 2 months of age AND a booster at 6 months >of age, thus has NO >antibodies left at 1 year of age! It's a good article. It's target toward goat owners, so it's not 100% applicable to sheep, but worth reading. I lost a goat yesterday to what I believe was enterotoxemia. I probably could have saved her if I'd had the anti-toxin on hand, so I strongly advise everybody to buy some. It's cheap insurance.
