Hepatitis B Vaccine Information

Mild side effects from the Hepatitis B vaccine usually last 1-2 days. Mild side effects of the vaccine include redness, swelling, or itching at the injection site; headache, dizziness, fatigue, irritability or agitation, especially in children, sore throat and fever. More serious side effects include back pain, blurred vision and confusion.

The National Vaccine Injury Compensation Program may provide compensation for: (1) anaphylaxis, which is an acute allergic reaction to the antigen in the vaccine; (2) Shoulder Injury Related to Vaccine, known as SIRVA, which is a sometimes-painful injury to the shoulder where the vaccine was administered, and (3) Vasovagal Syncope, which is when a person faints because his or her body overreacts to certain triggers, such as the sight of blood or extreme emotional distress.
