Side effects of Hep B vaccine

Hepatitis B vaccine (HBV)

The Hepatitis B Vaccine is generally regarded as a safe vaccine. But, as with any medical intervention or medication, it is not risk free. The following is a list of some of the possible side effects of the Hepatitis B Vaccine (HBV) when given to adults and babies.

The more commonly known side effects can include:

  • Temporary soreness at the injection site (5-15%).
  • Infection of the injection site (less than 1%).
  • Low grade fever (0.6% to 3.7% in babies, 2-3% in adults) within a day or so of the injection.
  • Nausea, dizziness, tiredness, aching muscles and joints in the day or so after the injection.

The very rare side effects can include:

  • A very high fever soon after the injection, believed to be due to a reaction because of a yeast allergy.
  • An allergic reaction to the vaccine soon after the injection (known as 'anaphylaxis'), reported in adults, about 1 in 600,000 (or 0.00016%). The person can develop an overall rash, look pale and feel faint; have a fast pulse and low blood pressure, in some cases having difficulty breathing and possibly stomach cramps and diarrhoea.
  • A condition called 'periarteritis nodosum' or 'polyarteritis nodosum', reported in adults. This is an autoimmune connective tissue disease affecting the outside of the small to medium arteries, causing them to become inflamed. This condition is believed to be an extremely rare reaction to the Hepatitis B vaccination but can shorten a person's life expectancy. It is believed the risks associated with the Hepatitis B virus, outweigh rare risks such as periarteritis nodosum.

There have been reports of certain conditions associated with the administration of the Hepatitis B Vaccine. However, at this stage there is no strong evidence to support the conclusion that this vaccine has caused these conditions. These include:
