Data source: VAERS (Vaccine Adverse Event Reporting System)

Data through 2026 · Updated quarterly

Built by TheDataProject.ai · © 2026 VaccineWatch

Important: VAERS accepts reports of adverse events following vaccination. For any given report, there is no certainty that the reported event was caused by the vaccine. Reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. Most reports to VAERS are voluntary, which means they are subject to biases. This data cannot be used to determine if vaccines cause or contribute to adverse events.

⚠️

Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

Why Vaccinate at Birth?

Hepatitis B can be transmitted from mother to infant during birth. Babies infected at birth have a 90% chance of developing chronic infection, which can lead to liver cancer and liver failure. Vaccination at birth provides immediate protection.

Some VAERS reports for hepatitis B involve very young infants, which can include health events that coincide with the neonatal period rather than being caused by the vaccine.

Expected Side Effects

Common:

  • Soreness at injection site
  • Mild fever
  • Fatigue

Rare:

  • Allergic reaction (very rare)
  • Temporary joint pain

Hepatitis B vaccine is considered one of the safest and best-studied vaccines available. It has been administered billions of times worldwide since its introduction in 1982.

⚠️ Remember: VAERS reports show correlation, not causation. A report filed after vaccination doesn't mean the vaccine caused the reported event. Always consult your healthcare provider for medical advice.
