Can I use homeopathic vaccines to protect my pet instead?

There is no legal requirement for homeopathic vaccines (or nosodes, as they're sometimes called) to perform efficacy or safety trials to satisfy the licensing authorities. In fact, where serious attempts have been made to prove efficacy - for example in a parvovirus challenge experiment - nosodes failed to prevent either illness or death.

We have no wish to disparage homeopathy in general; but there is certainly no evidence to suggest that homeopathic vaccines are powerful enough to protect against infectious diseases.
