1 Feline stomatitis is a severe, painful inflammation of a catâs mouth and gums. 2  Dental disease, certain viruses, and some other inflammatory conditions can cause feline stomatitis.  The long-term outcome can vary. Many cats require long-term treatment to control the condition.
Vaccine Adverse Event Reporting System. The Vaccine Adverse Event Reporting System (VAERS) is a United States program for vaccine safety, co-managed by the U.S. Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA).
The Centers for Disease Control admits that the reported number of adverse effects of vaccines is probably only 10% of actual adverse effects. The Physician's Desk Reference cites adverse reactions to the hepatitis B in less than 1 percent. However, if more than 70 million American children receive the vaccine, that means more than 700,000 children are likely to suffer adverse reactions.
