  5. Initial Vaccinations • Core vaccines • Adult horses • Initial 2 dose series 4-6 weeks apart • Re-vaccinate annually • Foals and Weanlings • Timing dependent on vaccination status of mare • Require 3 dose series

  6. Initial Vaccinations • Risk based vaccines • Adult horses • Initial 3 dose series 4-6 weeks apart* • Annual to semi-annual revaccination • Foals and Weanlings • 3 dose series for most vaccines • Most given around 6 months of age

  13. WEE Courtesy of Dr. Beatrice Sponseller

  14. WEE/EEE • Transmitted by mosquitoes • Fever and depression initially • Progresses to head pressing, blindness, muscle tremors

  15. WEE/EEE

  16. WEE/EEE • Vaccinate prior to mosquito season—Spring time best • Annual vaccination • 6 month revaccination • Horses in high prevalence area • Immunocompromised horses

  17. West Nile Virus Courtesy of Dr. Beatrice Sponseller

  18. West Nile Virus • Transmitted by mosquitoes • Mild fever, anorexia and depression • Gait abnormalities • Onset of neurologic signs are usually sudden • Personality changes • Muscle tremors

  19. West Nile Virus • Vaccinate prior to mosquito season—Spring time best • Annual vaccination • 6 month revaccination • Horses in high prevalence area • Juvenile (<5 years of age) • Geriatric horses (>15 years of age) • Immunocompromised

  20. Risk based vaccines

  21. Equine Herpes Virus • Transmitted by contact with infected horses and fomites • Two common subtypes • EHV-1 • Neurologic and respiratory signs • EHV-4 • Respiratory signs

  22. Equine Herpes Virus • Vaccinate annually • Initial 3 dose series • 6 month revaccination • Juvenile (<5 years) • Horses on breeding farms or in contact with pregnant mares • Performance or show horses at high risk • Pregnant mares • Vaccinate 5, 7 and 9 months of gestation

  23. Influenza • Highly contagious and transmitted through the air • Most commonly affects 2-3 year olds • Sudden onset of fever (103-105F), serous or mucopurulent nasal discharge, anorexia, depression and dry, deep cough

  24. Influenza • Vaccinate annually • Initial series depends on type of vaccine used • Modified live intranasal vs. inactivated injectable • 6 month revaccination • Horses with on going risk of exposure

  25. Potomac Horse Fever • Fever, anorexia, depression • Reduce gut motility/sounds proceed diarrhea • Diarrhea can be moderate to severe • Concurrent colic signs

  26. Potomac Horse Fever • Exposure to waterways and rivers increases risk • Peak incidence in July and August • Vaccinate semiannually to annually • Initial 2 dose series • Revaccination intervals of 3-4 months in areas of high prevalence for disease

  27. Strangles • Transmitted by contact with infected horses or fomites • Fever, lethargy, and serous nasal discharge • Affected lymph nodes usually are firm initially but soften before rupturing • Many affected will never have abscessed lymph nodes

  28. Strangles • Semi-annual to annual vaccination • 2 dose series for intranasal vaccine • 40% of exposed vaccinated horses will still get sick
