Vaccination is a method that helps prevent the spread of infectious diseases in animals by stimulating their immune system to recognize and fight off specific pathogens. When animals are vaccinated, they develop an immunity to certain diseases without actually suffering from the illness. This is critically important in controlling outbreaks, as vaccinated animals are less likely to become infected and thus less likely to transmit diseases to other animals.

Proper vaccination programs are designed based on the specific diseases endemic to a region or common within particular species. By ensuring that a population of animals is vaccinated, the overall herd immunity is increased, thereby reducing the incidence of disease and protecting not only the vaccinated individuals but also those who are not vaccinated due to health concerns or age.

In contrast, antibiotic treatment is typically used to treat infections that have already occurred rather than prevent them from spreading. Regular exercise contributes to overall health but doesn't have a direct role in controlling the spread of infectious diseases. Isolation can be effective for controlling diseases in specific cases, but it may not be feasible or effective in preventing the spread of diseases across larger populations or environments.
