The vaccines in catalogs are the same ones vets order. There are no differences. You must be careful when ordering though for several other reasons: 1. Vaccines must be refrigerated. When mailed, they have cool packs which do not last longer than a day. Order vaccines when the weather is cool or at the first of hte week with next day air so they don't sit in a hot truck all weekend. Also, try to order vaccines from the company located closest to you. 2. Rabies vaccines can be ordered by the "public" in only a few states. Most places will not ship rabies vaccines unless you are a vet or work for one. 3. Many other states require a license to order vaccines or syringes. Know your state laws or read the fine print in catalogs for details. [Posted in FML issue 1642]
