Question: What are the side effects of hepatitis vaccinations? I just got my hepatitis b shots in school today, please tell me what the side effects are! I got some side effects like less energy and sore body parts but what are other side effects.

Answer: Serious side effects after administration of the hepatitis B vaccine are extremely rare. There have been some anecdotal reports of the association of hepatitis B vaccination with chronic illness such as autoimmune disorders. However, there have been no scientific data supporting these claims. Large-scale immunization exercises have been ongoing in many other countries and in the United States, and thus far there has been no association of hepatitis B vaccination with serious adverse events. No clear association has been demonstrated between hepatitis B vaccination and disorders such as Guillain-Barre syndrome, transverse myelitis, optic neuritis, and seizures. Even then, such alleged associations are still being studied to further ensure the safety of the vaccine. A recent study demonstrated that persons who developed rheumatoid arthritis following hepatitis B vaccination were actually genetically susceptible to rheumatoid arthritis, making it difficult to correlate the occurrence of rheumatoid arthritis with hepatitis B vaccination. Considering the large number of doses of HBV vaccine administered and the very low numbers of serious adverse reactions, it is possible that adverse reactions reported after hepatitis B vaccination may represent coincidence rather than causation.
