here is something to read and what i got out of this that is critical for this thread is:
Vets are NOT required to report adverse reactions to vaccines This is why we do not see the true statistics of what is happening with vaccinations. Also many reactions show up as life long illnesses that are triggered by them and not necessarily a life or death situation after the vaccination. Again it states to be given to healthy dogs only.
