This is an excellent vaccine that I believe all horses should get. It is effective, a lot cheaper than a vet call and a sick horse, and did I mention it works great? Prevents illness due to Streptococcus equii, an upper respiratory virus.

Pros: prevents against Strangles/Strep

Cons: none

Great product for stangles prevention. Has fewer side effects than some strangles vaccines.

Pros: Great protection, ease of administration

Cons: None
