A dangerous disease that can cause inflammation in the brain, Rabies can spread through the bite of infected animals. This vaccine provides up to 14 months of protection and is safe for use in horses and foals over 4 months of age. Merck’s proprietary Havlogen adjuvant stimulates the immune system and helps the vaccine maintain suspension in the bottle.
