Vaccine Safety
The hepatitis B vaccine is considered one of the most safe and effective vaccines ever produced. In the U.S., 40 million Americans have received the vaccine. Outside the U.S., 750 million persons have received the vaccine. Three shots can protect a person for a lifetime.

| chronic illness | seizures |
| multiple sclerosis | sudden infant death syndrome (SIDS) |
| guillain-barre syndrome | chronic fatigue syndrome |
| transverse myelitis | rheumatoid arthritis |
