This vaccine is used for horses that are older than 9 months of age, it helps protect against rhinopneumonits and will also help protect pregnant mares against abortions that could be caused by the sickness. This vaccine prevents respiratory diseases from EHV 1P and EHV 1b and EHV 1 which can cause abortions in pregnant mares.

In pregnant mares it should be administers at the fifth, seventh, and ninth month of pregnancy, Pneumabort-K is the only vaccine with federal approval to prevent abortions it is sold in 1 dose syringes and also in 10 dose vials, it should be kept cold at all times avoiding freezing, and once it is opened entire contents should be used.

Horses with a history of EHV infection and disease, including neurological disease, are likely to have immunity consequent to the infection that can be expected to last for 3 to 6 months or longer in older horses. Booster vaccination can be resumed 6 months after the disease occurrence.

While this approach does not guarantee protection of individual horses against the potentially fatal neurological form of EHV-1, the hope is that reduced nasal shedding of infectious EHV-1 by recently vaccinated horses will indirectly help protect other horses by reducing the dose of virus to which they are exposed.
