Discussion on Strangles Intranasal - Problems | |
Author | Message |
Posted on Saturday, Apr 1, 2000 - 12:06 pm: I am reporting the problem my barn is currently having after administering the Pinnacle Intranasal Equine Strangles Vaccine (Fort Dodge Animal Health).Several horses in our barn developed abscesses after being given the Pinnacle Intranasal Vaccine and their regular immunization shots at the same time. Thanks Dr. O. for the good coverage in the articles Administering Intranasal Modified Live Vaccines and Vaccines and Vaccination Schedules for Horses. Both have pin pointed what we believe caused the problem, administering the intranasal at the same time as the injection. We have been told that Fort Dodge Animal Health mailed out "Dear Dr." letters about this problem, however our vet did not receive one. While it's late for me to be reading this, I'm glad the information is presented for other horse owners. First of all I wanted to spread a work of caution to those using or considering using this or other intranasal vaccines. BE SURE TO FOLLOW DR. O's GUIDELINES, washing hands after giving this vaccine is extremely important. Don't give injectables at the same time. Second, I'm hoping that someone will be able to give advice on the follow up care. (If anyone has the text of the cautionary letter from Fort Dodge, I would appreciate you posting it.) The horses developed abscesses at the injection site ranging in severity from small to over softball size. These developed several days after the vaccination was given. They also have troubles bending their necks downward (this varies among the horses). The abscesses have been lanced and cultured (informal report is that while it is infection, there was a lot of pus, no strangles is present). They are on injected penicillin and an oral antibiotic. This treatment only started this week, however all seem to be doing well, just seeming a little "off" in their attitude (vaccinations were given approximately 2 weeks ago). Hopefully now that the abscesses are draining, this will clear up soon. Dr. O. other than the antibiotics, is their any other course of treatment that should be considered in this situation. I was one of the luckier horse owners, as my horse did not have the reaction. However are there any precautions I should take? I'm also trying to decide whether or not to go through with the second dose of the intranasal since my horse appears to have responded normally. I'm worried about a lesson horse my kids may show this summer. He had one of the strongest reactions. We are also concerned about an older horse that developed one of the larger abscesses. At his age, is there an increased chance of bastard strangles? (I did read the tip in another post about using temperature readings to "monitor" the internal abscess formation.) Even though it appears that the infection is localized, our barn manager is using extreme precautions making sure that while the abscesses are draining, infection is not transmitted any further. I appreciate any insight or recommendations. |

Posted on Sunday, Apr 2, 2000 - 11:31 am: This complication is becoming increasingly reported. It is not the administration of the vaccine that is causing these reactions. It is the contamination of injection sites prior to the injection that is causing this problem. WHen you give the inection you are pushing the attenuated Strangles into the muscle.You can give the IN Strangles with the other injections as long you follow the rules: Before even touching the Pinnacle the other injections need to be pulled up and administered to prevent contamination of the injection sites. I would think (am pretty sure) EARLY administration of Penicillin would short circuit abscess formation. But the problem is one of diagnosis: the other injections can cause nonabscess reactions that look the same. DrO |
