Karen Taylor asked:
How often should our dogs be re-vaccinated (boosters)?
Hi Karen, thanks for your question about booster vaccinations. This is an area that’s become quite controversial in the last few years, and there’s a lot of confusion about the subject. In addition, there’s a lot of very poor-quality information out there, so I’ll try to make this quite clear and obvious!
To put it as simply as possible – see your vet every year for a health check, and discuss your vaccination strategy with them.
For more detail… now read on!
What are vaccinations?
Put simply, a vaccination is a way of teaching your dog’s immune system how to recognise and defeat the micro-organism that causes an infectious disease, without the risks (of illness, potential long term health problems or death) inherent in a “natural” infection.
This is achieved in one of three ways:
1) A weakened form of the disease-causing organism.
These are called “modified live” or “attenuated” vaccines, e.g. for Distemper and Parvovirus; the organism included is unable to multiply and/or cause clinical disease, but it is active enough to stimulate a strong immune response. Most modified live vaccines give a stronger and more long-lasting immune response than an inactivated vaccine; however, they aren’t suitable for every disease (because some organisms cannot be weakened enough to make them safe)…
