1. What is IXCHIQ and what is it used for

IXCHIQ is a vaccine that helps protect adults 18 years of age and older against disease caused by the chikungunya virus (CHIKV).

Chikungunya is a disease caused by the chikungunya virus (CHIKV), which is found in subtropical regions of the Americas, Africa, Southeast Asia, India, and the Pacific region. CHIKV is transmitted to humans through the bite of an infected mosquito. Most people infected with CHIKV develop sudden fever and intense pain in several joints. Other symptoms may include headache, muscle pain, joint swelling, or skin rash. These symptoms usually disappear within 7 to 10 days but can last for months or years.

Consult your doctor, pharmacist, or nurse before deciding whether you should receive this vaccine.

How the vaccine works

IXCHIQ works by teaching the immune system (the body's natural defenses) to defend against CHIKV. The vaccine contains a weakened form of the virus that has been weakened in the laboratory so that it cannot multiply. When the body encounters this weakened version of the virus, the immune system recognizes it and produces antibodies to attack it. When a vaccinated person later comes into contact with the virus, their immune system will recognize it and be prepared to defend the body. This helps prevent illness.

2. What you need to know before you receive IXCHIQ

The vaccine must not be administered:

  • If you are allergic to the active substance or any of the other components of this vaccine (listed in section 6).
  • If your immune system has a reduced ability to fight infections and other diseases (immunodeficiency) or if you have a weakened immune system (immunocompromised) due to a disease or medication (such as cancer and chemotherapy, inherited immune problems, prolonged use of medications that weaken the immune system, such as corticosteroids or immunosuppressants, or HIV infection).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before receiving IXCHIQ:

  • If you have had a severe allergic reaction after receiving any other injectable vaccine.
  • If you have ever fainted after an injection with a needle or if needles or injections cause you anxiety.
  • If you have a bleeding problem, bruise easily, or are taking anticoagulant medications (to prevent blood clots).
  • If you have had a recent fever (body temperature above 38°C). However, you may be vaccinated if you have a mild fever or an upper respiratory tract infection, such as a cold.

Do not donate blood for at least 4 weeks after being vaccinated with IXCHIQ.

If you are unsure if any of the above applies to you, consult your doctor, pharmacist, or nurse before receiving the vaccine.

It is possible that IXCHIQ may not completely protect all people who receive the vaccine. IXCHIQ does not protect against other mosquito-borne diseases.

You must protect yourself from mosquito bites even after receiving the IXCHIQ vaccine. If you travel to countries where the chikungunya virus is still present, use insect repellent, wear long-sleeved pants and shirts, and stay in air-conditioned or screened areas.

Children and adolescents

IXCHIQ has not been fully tested in young people under 18 years of age. It must not be used in this age group.
