zoetis Pneumabort K + 1b Horse Vaccine

For pregnant mares:  Aseptically administer one 2-ml dose intramuscularly during the fifth, seventh and ninth months of each pregnancy.
For young horses (to aid in the prevention of EHV-1 respiratory infections):  Aseptically administer one 2-ml dose intramuscularly after weaning, followed by a second 2-ml dose 3 to 4 weeks later. Revaccinate with a single 2-ml dose 6 months after the second primary dose and annually thereafter.
To ensure proper placement and retention of the vaccine, inject deep into the heavy muscles of the hindquarter.
Mild exercise to promote absorption is recommended for 1 week after injection.

• Maiden and barren mares which come in contact with vaccinated pregnant mares should be vaccinated on the same schedule as the pregnant mares with which they are in contact.
• Mares more than 5 months pregnant at the time of arrival on a farm should be vaccinated upon arrival and at 2-month intervals until foaling.
• Pregnant mares which are in contact with mares having aborted EHV-1 infected fetuses should be vaccinated. Such vaccination may provide immunity for those mares in the group which are not incubating an abortigenic infection at the time of vaccination.
