[Hepatitis A Vaccine, Inactivated]
- Patient Information:
Details with Side Effects
VAQTA [Hepatitis A Vaccine, Inactivated] is an inactivated whole virus vaccine derived from hepatitis A virus (HAV) grown in cell culture in human MRC-5 diploid fibroblasts. It contains inactivated virus of a strain which was originally derived by further serial passage of a proven attenuated strain. The virus is grown, harvested, purified by a combination of physical and high performance liquid chromatographic techniques developed at the Merck Research Laboratories, formalin inactivated, and then adsorbed onto amorphous aluminum hydroxyphosphate sulfate. One milliliter of the vaccine contains approximately 50 units (U) of hepatitis A virus antigen, which is purified and formulated without a preservative. Within the limits of current assay variability, the 50U dose of VAQTA (hepatitis a vaccine, inactivated) contains less than 0.1 mcg of non-viral protein, less than 4 x 10–6 mcg of DNA, less than 10–4 mcg of bovine albumin, and less than 0.8 mcg of formaldehyde. Other process chemical residuals are less than 10 parts per billion (ppb).
VAQTA (hepatitis a vaccine, inactivated) is a sterile suspension for intramuscular injection.
VAQTA (hepatitis a vaccine, inactivated) is supplied in two formulations:
Pediatric/Adolescent Formulation (12 Months Through 18 Years of Age): each 0.5 mL dose contains approximately 25U of hepatitis A virus antigen adsorbed onto approximately 0.225 mg of aluminum provided as amorphous aluminum hydroxyphosphate sulfate, and 35 mcg of sodium borate as a pH stabilizer, in 0.9% sodium chloride.
Adult Formulation (19 Years of Age and Older): each 1 mL dose contains approximately 50U of hepatitis A virus antigen adsorbed onto approximately 0.45 mg of aluminum provided as amorphous aluminum hydroxyphosphate sulfate, and 70 mcg of sodium borate as a pH stabilizer, in 0.9% sodium chloride.
What are the possible side effects of hepatitis A vaccine (Havrix, Vaqta)?
You should not receive a booster vaccine if you have ever had a life-threatening allergic reaction after the first shot.
Keep track of any and all side effects you have after receiving this vaccine. When you receive a booster dose, you will need to tell the doctor if the previous shots caused any side effects.
Becoming infected with hepatitis A is much more dangerous to your health than receiving the vaccine to protect against it. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.

What are the precautions when taking hepatitis a vaccine, inactivated (Vaqta)?
Before getting hepatitis A vaccine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients (such as neomycin, formalin, latex in some vials/prefilled syringes), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: bleeding problems (such as hemophilia, low platelets, anticoagulant treatment), current illness with fever.
If you have decreased immune function from other medications (see also Drug Interactions) or other illness (such as HIV, leukemia, lymphoma, other cancer), your body may not make enough antibodies to protect you from hepatitis A...
