Havrix is a vaccine used to lower your risk of getting hepatitis A, which is a liver infection caused by the hepatitis A virus. This vaccine is given as an injection into the muscle. It's a routine vaccine that everyone should receive as a child. It's also recommended for people traveling to areas where hepatitis A is common.
Prevention of hepatitis A
Havrix is an inactivated vaccine that protects you from getting infected with the hepatitis A virus. The vaccine helps your body's immune system make antibodies that will attack the virus if it ever infects you.

Read the vaccine information statement for more information on the hepatitis A vaccines.
Receiving Havrix doesn't guarantee that you won't get infected with the hepatitis A virus. In addition to the vaccine, take all necessary precautions while traveling to areas where hepatitis A is common to avoid getting sick from unclean food and drinks. Some examples include avoiding raw foods, street food, bushmeat (animals not typically eated in the United States), tap water, ice, and freshly squeezed juice.
There is no specific treatment or cure for hepatitis A. If you're exposed to hepatitis A, it's recommended you get medical attention as soon as possible, regardless of vaccination status, so you can get the care you need.
Make sure to keep a record of all your immunizations and show it to your provider or pharmacist before receiving any vaccine, including Havrix, to make sure you're receiving all your vaccines on schedule.
Wait until you're healthy to get Havrix. This will help make sure your immune system protects you as best as it can. If you have a mild sickness, such as a cold or low-grade fever, you can still get Havrix. But if you feel moderately to severely sick, wait until you recover before getting this vaccine. Ask your provider if you're not sure whether or not you can get this vaccine.
If you experience a severe reaction to Havrix, you or your provider can report it to the vaccine adverse event reporting system (VAERS) website or by calling 1-800-822-7967.
Havrix can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Latex allergy | Allergy to neomycin | Allergic reaction to other vaccines
As with any vaccine, there's a rare chance that you might have a severe allergic reaction to Havrix. Your risk is higher if you're allergic to latex because the prefilled syringes contain natural rubber latex. If you have an allergy to neomycin, be aware that Havrix contains a small amount of this ingredient.
Your provider might ask you to stay at the pharmacy or clinic for a short period of time after you've received your vaccine to make sure you can get proper care in case of a serious allergic reaction. Sometimes, these reactions can happen after you've already left the clinic. Get medical help right away if you notice symptoms of a severe allergic reaction, such as closing of the throat, difficulty breathing, hives or rash, swelling of the face, feeling faint, dizziness, shaking, nausea, or chest pain.
Risk factors: Medical conditions that weaken the immune system | Taking medications that lower your immune system
Havrix might not work as well in people with a weakened immune system. This can put you at higher risk of hepatitis A, even after you've received the vaccine. If you have any medical conditions (e.g., HIV (human immunodeficiency disease) or cancer) or take medications that weaken your immune system (e.g., high-dose corticosteroids, transplant medications, cancer medications), talk to your provider first before receiving Havrix.
Havrix is given by a healthcare provider as an injection into the thigh muscle for children 12 to 23 months of age and into the shoulder muscle for adults and children at least 2 years old.
The hepatitis A vaccination series consists of 2 injections into the muscle, given at least 6 months apart.
For children aged 1 to 18 years of age, each injection is 0.5 mL.
For adults, each injection is 1 mL.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
