Hepatitis B is a contagious virus that causes damage to the cells of the liver that can eventually lead to cirrhosis and liver cancer. Hepatitis B can be contracted through child-birth, sexual contact with an infected partner and contaminated needles. Getting the hepatitis B vaccine can offer additional protection against the disease. There are some side effects associated with this vaccination.
Fever
According to the Centers for Disease Control and Prevention, or CDC, up to about one person in 15 may develop a fever of 99.9 degrees Fahrenheit after vaccination with the hepatitis B shot. Physicians may recommend the use of an over-the-counter medication such as acetaminophen for the relief of fever following vaccination. Some pediatricians may recommend giving acetaminophen prior to vaccinating a child. Any fever that persists or worsens should be brought to the attention of a doctor. If a patient is ill with something more serious than a cold the vaccination may be postponed until a later date, says MedlinePlus.
Injection Site Complications
Patients may develop an injection site reaction following vaccination with the hepatitis B shot. Symptoms can include redness, swelling, tenderness, and soreness at the site of injection. Some people may develop a small bruise at the affected area. The application of a cool compress may help to reduce swelling and soreness at the site. Parents of vaccinated children should use caution while holding and changing the child as not to place additional pressure on the site of injection. Up to about one person in four may experience these effects, reports the CDC.
Moderate or Severe Side Effects
In some cases, the hepatitis B vaccine may cause a moderate or severe side effect. Symptoms can include high fever, behavior changes, difficulty breathing, wheezing, hives, paleness, weakness, a fast heart beat or dizziness, says the CDC. Patients who are allergic to bakers yeast or those who have had a serious reaction to a hepatitis vaccine in the past should not receive this vaccine. Those who experience these side effects following vaccination should seek immediate medical attention.
