The hepatitis A vaccine provides protection against the hepatitis A virus. The vaccine, called Havrix or VAQTA, is made from inactivated whole virus of hepatitis A, states Medline. This means that you are being injected with the hepatitis A virus, but it is not in its active form. You will not get hepatitis A from this vaccination. This vaccine is given as a two-part series, with the second dose recommended within 6 to 12 months of the first dose. This vaccine is recommended for those who travel internationally, those who use injectable drugs, homosexual men, military personnel, and those with chronic liver disease. Speak with your physician if you think you may be a candidate for the hepatitis A vaccine. There are some side effects of this vaccination that you should be aware of.
Injection Site Complications
You may experience redness, swelling, or bruising at the injection site, states Medline. These side effects should diminish within a few days following vaccination. You can use a cold compress to alleviate injection site swelling. For discomfort, acetaminophen or ibuprofen may be used with your doctor's consent. According to the Centers for Disease Control and Prevention (CDC), this side effect occurs in about 1 out of 2 adults, and up to 1 out of 6 children.
Headache and Fever
Headache and fever may occur following vaccination for hepatitis A. These side effects should only last for a couple of days following vaccination. An over-the-counter pain reliever such as acetaminophen or ibuprofen will help manage headache and diminish fever. If headache and fever persist and become severe, contact your healthcare provider. It may be a sign of something more serious that does not involve your recent vaccination.
Muscle Aches and Fatigue
You may experience muscle aches and fatigue after vaccination with the hepatitis A vaccine. Your muscles may ache or feel sore, and you may feel more tired and sleepy than usual. Check with your healthcare provider to see if you may use acetaminophen and ibuprofen to relieve these symptoms.
Loss of Appetite and Nausea
Following hepatitis A vaccination, you may experience loss of appetite, an effect that occurs in approximately 1 out of 12 children, according to the CDC. You also may experience nausea after receiving the vaccine. Eating a bland diet with smaller meals more frequently may help alleviate nausea. Liquid nutritional supplementation, such as Pediasure (for children) or Boost (for adults), can be used in those who experience loss of appetite and nausea.
