Do you know what is really in the vaccines that are given to your pet? Vaccines are used to build immunity against certain diseases and will contain a modified or killed form of the organism. Vaccines also contain other ingredients that may cause adverse reactions in your pet. All vaccines will have preservatives of some sort. These are typically either antibiotics and/or thimerosal, which is a mercury based preservative. Vaccine companies and the FDA will consider these substances safe if present in certain low percentages. The problem is that you never know how a certain individual is going to react to even a small amount of a chemical or antibiotic.
I recommend that you ask what is in the vaccine that is being given your pet. I have also found that package inserts are not complete. In an effort to investigate the ingredients in a certain rabies vaccine that we have in our clinic, I found that the package insert only listed gentamycin as a preservative. When I contacted the company asking about any other ingredients, I was sent the MSDS (material safety and data sheet ) that report the presence of neomycin(another antibiotic) and thimerosal. You can ask to see the MSDS sheets or find them your self online if you know the brand of vaccine that is to be used on your pet.
Remember – vaccines are not benign and may contain other substances with the potential to cause reactions in your pet. You have the right to be informed and deserve full disclosure of what your pet is receiving.
