Strangles is a highly contagious upper respiratory tract infection spread by direct or indirect contact with infected horses. Horses of all ages are susceptible to Strangles, which is caused by Steptococcus equi infection. Strepvax® II is an equine vaccine approved for vaccinating healthy horses of all ages as an aid in the prevention of Strangles due to Streptococcus equi infection.

Strepvax® II contains a killed bacteria and is well tolerated by most horses. When combined with good hygiene and isolation of affected individuals, Strepvax® II will help to limit the occurrence of clinical disease. This is the only S. equi vaccine that can be administered to horses intramuscularly (IM), providing ultimate convenience.

Supplied as a single dose syringe (with needle) or 10 dose bottle (needles and syringes sold separately).

Do you only give 3 doses for the first vaccination and then just once annually per year after that? I assume that but I wanted to be certain that I don't have to vaccinate 3x per year because I don't want to improperly vaccinate.

Hi! Thanks for the question. You will need to consult with your veterinarian about questions concerning proper dosage.

Is the strep and Vetera Gold XP+VEE dose the same for miniature horses as it is for full size horses?

Asked by: Cathy
Hello there! That is a great question for your vet! Most dosages are based on 1000 lb horses so I would get their advise for exact dosing!

Rated 5 out of 5 by from Strepvax II - Strangles preventionI use this vaccine for all my horses because some of them go to shows, trail rides and clinics where they can be exposed to Strangles from all the other horses present. Don't want the traveling horses to bring home germs to my broodmares and foals.
