1. Monovalent Vaccines
These are vaccines that provide protection for one disease at a time. The rabies vaccine is a good example. Only the rabies viral agent is added to the liquid in this vaccine.
2. Multivalent Vaccines
In a multivalent vaccine, several bacterial or viral agents are added to the liquid the dog will ingest. Sometimes up to 8 or 9 diseases are addressed in one vaccine. There is usually a core vaccine, such as one called Duramune that protects against 4 of the most common dog viruses in one.
3. Modified Live Vaccines (MLV)
4. Killed Vaccines
In this type of vaccine, the actual viruses or bacteria are
killed and then put into the liquid. There's no way they can multiply
within the pet's body. Thus, more of the particles are introduced in
hopes of triggering the immune response. There are also added chemicals
to help the process. The disadvantage of this can be an increased risk
that the dog will develop an allergic response.
5. Recombinant Vaccines
Certain antigens on infectious organisms stimulate a greater antibody response than others. In a recombinant vaccine, a laboratory technician breaks up the genes of the virus and isolates the parts that will produce the best immune response. In this vaccine, the whole virus is not present, which creates safety for the animal.
6. Injectable Vaccines
Some vaccines are injected into the dog's muscle or under his skin. The first is called intramuscular and the second subcutaneous. Some vaccines can be given either way, but the rabies vaccine, for example, has to be given intramuscularly. In any injectable vaccine, the eyes, nose and mouth must be avoided.
