Reactions to EI Vaccine
See posts for 20th December - I believe a family on the NSW south coast had a horse die after being vaccinated. There should be an investigation into this currently taking place, you may be able to get in contact with the owners for advice and information as to the symptoms, possible causes etc.
I am not a vet, I am an informed person, but I understand that the flu injection may cause reactions in several ways.
The horse may be allergic to the substance used as a carrier for the modified virus.
I imagine that a horse already exposed to EI may have a reaction when the vaccine is administered as naturally-acquired antibodies may already be present.
I believe vets are administering anti-tetanus shots as part of the microchipping process, this may be to blame for your horse's adverse reaction rather than the EI vaccine itself.
A horse may develop an unrelated infection due to bacteria being introduced by a poorly-administered injection, this could result in the symptoms you have described.
Another problem with injections is air embolism, but this is usually fatal within a very short time.
Your vet should be able to discuss the various possible causes and determine what is the best treatment under the circumstances.
Even with a vaccine that is regarded as "safe", there will be some individuals who suffer extreme reactions. There are also risks associated with ANY type of veterinary intervention. However, statistics are no comfort if you are the owner of the "one-in-a-thousand" that experiences unlikely negative outcomes.
Best of luck, hope you get some satisfactory answers and that your filly gets better soon,

Very interesting reading to be had at https://www.animalhealthaustralia.com.au/shadomx/apps/fms/fmsdownload.cfm?file_uuid=955FA5A8-C0D0-9FAC-3E32-33DC206BDC68&siteName=aahc
This is the 'proof' of the updated AUSVETPLAN regarding Equine Influenza, it is coincidentally dated 24th August 2007 and makes no mention of the current outbreak. HOWEVER, in the vaccination section it makes references to racehorses being a vaccination priority in order to continue racing, it also mentions that horses owned by individuals are a low priority. The timing and content of this document is highly suspect. I would like to know what others think.
