Livestock vaccination campaigns are often favorites of the humanitarian aid community because they engage a lot of local people, can spend large sums of money relatively quickly, and popular sentiment is that “you can’t go wrong with vaccinations, right?”
The answer, as with most things, is that you CAN go wrong with vaccinations if the specific circumstances are not carefully considered.
Mass vaccination of livestock is a potent tool in controlling and preventing diseases, safeguarding what in many societies comprises the most important single family resource. On the other hand, poorly thought-out campaigns may provide little benefit for animal owners. At worst, they can render animals even more vulnerable to disease.
