we do not want dogs to have to endure an episode of disease to develop
their own protection, we turn to the creation of active immunity by
vaccination. This is the deliberate triggering of the immune
response by the giving of a small, weak dose of the disease in order to
stimulate the production of anti-bodies.
vaccines are divided into four main categories:
The lethal effect of some organisms is brought about by the fact that they produce poisonous substances called toxins. The body reacts to these by producing specific anti-bodies called anti-toxins which are capable of neutralising toxins. This can be done artificially by injecting a toxoid which is a detoxified toxin. Toxoids are generally made by inactivating toxins either by heat or chemical means and on injection they stimulate immunity and booster doses may be needed over 1, 2, or 3 years.
4. Mixed Vaccines
It is possible to make mixed vaccines provided that care is taken to ensure the compatability of the antigens. Mixed vaccines may contain, for example, two live antigens, several dead antigens or even a combination of live and dead antigens. Such vaccines make it possible to establish an effective degree of protection against diseases with a minimal number of injections.
