The potential benefits of immunostimulants as vaccine adjuvants or prophylactic treatments have been investigated.
Vaccine adjuvants are administered with a vaccine to increase the speed and magnitude of the immune response to vaccination. They are particularly helpful in vaccines with low immunogenicity.
Immunostimulation may also be used prophylactically to lower the risk of infection in animals and reduce mortality rates.
As understanding of the immune system improves, the potential for improving animal welfare through immunomodulation increases. However, it is important to acknowledge that sustained stimulation of the innate immune response may not be appropriate, and the potential implications of any therapeutic intervention should be considered.
