Ixchiq (cvx 317)

This vaccine is used to prevent disease caused by the chikungunya virus in adults who are at high risk of being exposed to the virus.

This vaccine will not treat an active infection that has already developed in the body, and will not protect against other diseases spread by mosquitoes.

Like any vaccine, the chikungunya vaccine may not provide protection from disease in every person.

Tell your doctor if you take other medicines or have any other medical conditions or allergies.

You should not use chikungunya vaccine if you are allergic to it or its ingredients, or if you have a weak immune system (caused by disease or by using certain medicines).

Tell your doctor if you have or have ever had:

• a bleeding or blood clotting disorder such as hemophilia;
• an allergic reaction to any vaccine;
• any other medical condition; or
• any illness with a fever above 100.5 degrees F (38.0 °C).

Tell your doctor if you are pregnant or plan to become pregnant. Your doctor should decide if you need this vaccine, especially if you have a high risk of infection with chikungunya. Having chikungunya during pregnancy may cause complications or medical problems for the baby.

If you are pregnant, your name may be added to a pregnancy registry to monitor the effects of chikungunya vaccine on the baby.

Inform your baby's doctor if you received chikungunya vaccine during pregnancy, especially within the last 14 days before giving birth. It is not known if the chikungunya vaccine will pass the virus to the baby.

Ask a doctor if it is safe to breastfeed after receiving this vaccine.

Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Chikungunya vaccine may cause low white blood cell counts. This usually happens within the first week after getting the vaccine. Tell your doctor if you have fever, mouth sores, skin sores, sore throat, or cough. Your white blood cell counts may return to normal within 1 month.

You may have a severe reaction after receiving the vaccine. Call your doctor right away if you have fever, weakness, tiredness, headache, or severe muscle, back, or joint pain. These symptoms may interfere with your daily activities, may require a hospital stay, or may last for weeks or months.

Common side effects of Ixchiq may include:

• pain, redness, swelling, or tenderness where the vaccine was injected;
• headache, fever, weakness, tiredness; or
• muscle or joint pain.

This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.

This vaccine is given as a one-time injection (shot) into a muscle. You will receive this vaccine in a doctor's office, clinic setting, or pharmacy.

You may faint after receiving the chikungunya vaccine. You will be watched for a short time to make sure you are safe.

You should still use protection against mosquito bites even after you have received the vaccine. This includes wearing the appropriate clothing, insect repellents, and mosquito nets.

Since chikungunya vaccine is given as a one-time injection, you are not expected to follow a dosing schedule.

Since this vaccine is given by a healthcare professional, it is unlikely that you will receive too much chikungunya vaccine.

Follow your doctor's instructions regarding any limitations on food, drinks, or activities.

Before getting this vaccine, inform the doctor about all other vaccines you have had recently.

Also inform the doctor about all your other medicines, particularly:

• a blood thinner--warfarin, Coumadin, Jantoven.

This list is not complete. Other drugs may interact with chikungunya vaccine, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are included in this medication guide.
