Vaccination Frequently asked Questions

(Also see the AAEP recommendations for immunization)

Q. Why shouldn't I give all my horse's vaccines at the same time?

A. Giving every vaccine at once potentially stresses your horse more than is necessary. The immunity may not be as high, as the system attempts to react to many different antigenic challenges. Fewer vaccines at a time likely allow the immune system to concentrate specifically and mount a more effective defense. 

Q. Why should I give Flu/Rhino vaccine multiple times a year?

A. Immunity from the Flu/Rhino vaccine is short lived-about two months. Some experts believe that "over vaccination" may contribute to increased susceptibility to the neurologic form of Rhino. Every three months (four times a year) is an effective happy medium, important for active, traveling horses

Q. Should my horse get the strangles vaccine?

A. Strangles, or Strep equi, is a very contagious bacterium that typically causes respiratory infections and swollen lymph n odes. The vaccine(Pinnacle I.N.) is very effective in decreasing infections and stopping outbreaks. This intranasal vaccine has been safer and much less reactive than the intramuscular type. Due to possible rare immune reactions, it is recommended that blood be drawn for a titer prior to the first vaccine in older horses, or those that may have been exposed to the disease. It is usually a recommended vaccine. 

Q. Should my horse get the Potomac Horse Fever (PHF) vaccine?

A. PHF is typically a severe diarrhea caused by protozoa (Ehrlichia). There have been several cases in the area over the fast few years, likely picked up by drinking contaminated water from streams. This very effective vaccine is recommended.
