1. What Qdenga is and what it is used for
Qdenga is a vaccine. It is used to help protect you or your child against dengue. Dengue is a disease caused by serotypes 1, 2, 3, and 4 of the dengue virus. Qdenga contains weakened versions of these 4 serotypes of the dengue virus, so it cannot cause the disease.
Qdenga is administered to adults, adolescents, and children (from 4 years of age).
Qdenga should be used in accordance with official recommendations.
How the vaccine works
Qdenga stimulates the body's natural defenses (immune system). This helps protect against the viruses that cause dengue if the body is exposed to these viruses in the future.
What is dengue
Dengue is caused by a virus.
- The virus is transmitted through mosquitoes (Aedes mosquitoes).
- If a mosquito bites a person with dengue, it can transmit the virus to the next people it bites.
Dengue is not transmitted directly from person to person.
The signs of dengue include fever, headache, pain behind the eyes, muscle and joint pain, sensitivity or discomfort (nausea and vomiting), swelling of the lymph nodes or skin rash. The signs of dengue usually last from 2 to 7 days. You or your child may also be infected with the dengue virus but not show signs of illness.
Occasionally, dengue can be severe enough for you or your child to need hospitalization, and in rare cases, it can cause death. Severe dengue can cause high fever and any of the following symptoms: severe abdominal pain, persistent nausea (vomiting), rapid breathing, severe bleeding, stomach bleeding, gum bleeding, fatigue, restlessness, coma, seizures, and organ dysfunction.
2. What you need to know before you or your child receive Qdenga
To ensure that Qdenga is suitable for you or your child, it is important that you inform your doctor, pharmacist, or nurse if any of the following points apply to you or your child. If there is anything you do not understand, ask your doctor, pharmacist, or nurse to explain.
Do not use Qdenga if you or your child
- are allergic to the active substances or any of the other ingredients of Qdenga (listed in section 6).
- have had an allergic reaction after receiving Qdenga in the past. The signs of an allergic reaction can include an itchy rash, difficulty breathing, and swelling of the face and tongue.
- have a weakened immune system (the body's natural defenses). This can be due to a genetic defect or an HIV infection.
- are taking a medicine that affects the immune system (such as high doses of corticosteroids or chemotherapy). Your doctor will not use Qdenga until 4 weeks after you stop treatment with this medicine.
- are pregnant or breastfeeding.
Do not use Qdenga if any of the above apply.
Warnings and precautions
- Tell your doctor, pharmacist, or nurse before receiving Qdenga if you or your child:
- have a feverish infection. Vaccination may need to be postponed until recovery.
- have ever had health problems when given a vaccine. Your doctor will carefully weigh the risks and benefits of vaccination.
- have ever fainted after an injection. Fainting, dizziness, and occasionally falls (especially in young people) can occur after or even before any injection with a needle.
Important information about the protection provided
As with any vaccine, Qdenga may not protect all those who receive it, and protection may decrease over time. You or your child can still get dengue from mosquito bites, including severe dengue. You or your child should continue to protect themselves against mosquito bites even after vaccination with Qdenga.
After vaccination, you or your child should consult a doctor if you or your child think you or your child may have a dengue infection and have any of the following symptoms: high fever, severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums, fatigue, restlessness, and blood in the vomit.
Other protective measures
You or your child should take precautions to avoid mosquito bites. This includes using insect repellents, protective clothing, and mosquito nets.
Young children
Children under 4 years of age should not receive Qdenga.
Other medicines and Qdenga
Qdenga can be administered with the hepatitis A vaccine, the yellow fever vaccine, or the human papillomavirus vaccine at a different injection site (a different part of the body, usually the other arm) during the same visit.
Tell your doctor or pharmacist if you or your child are using, have recently used, or might use any other medicine or vaccine.
In particular, tell your doctor or pharmacist if you or your child are taking any of the following substances:
- Medicines that affect the body's natural defenses (immune system) such as high doses of corticosteroids or chemotherapy. In this case, your doctor will not use Qdenga until 4 weeks after you stop treatment. This is because Qdenga may not work as well.
- Medicines called "immunoglobulins" or blood products that contain immunoglobulins, such as blood or plasma. In this case, your doctor will not use Qdenga until 6 weeks and preferably 3 months after you stop treatment. This is because Qdenga may not work as well.
Pregnancy and breastfeeding
Do not use Qdenga if you or your daughter are pregnant or breastfeeding. If you or your daughter:
- are of childbearing potential, you or your daughter should take precautions to avoid becoming pregnant for a month after vaccination with Qdenga.
- think you or your daughter might be pregnant or are planning to have a baby, ask your doctor, pharmacist, or nurse for advice before using Qdenga.
Driving and using machines
Qdenga has a minor influence on the ability to drive and use machines in the first few days after vaccination.
Qdenga contains sodium and potassium
This medicine contains less than 1 mmol of sodium (23 mg) per 0.5 ml dose; i.e., it is essentially "sodium-free".
This medicine contains less than 1 mmol (39 mg) of potassium per 0.5 ml dose; i.e., it is essentially "potassium-free".
3. How Qdenga is administered
Qdenga is administered by a doctor or nurse as an injection under the skin (subcutaneous injection) in the upper arm. It must not be injected into a blood vessel.
You or your child will receive 2 injections.
The second injection is administered 3 months after the first.
There are no data in adults over 60 years of age. Consult your doctor to see if Qdenga is beneficial for you.
Qdenga should be used in accordance with official recommendations.
Instructions for preparation of the vaccine for doctors and healthcare professionals are at the end of the leaflet.
If you or your child miss a Qdenga injection
- If you or your child miss a scheduled injection, the doctor will decide when to administer the missed injection. It is important that you or your child follow the doctor's, pharmacist's, or nurse's instructions regarding the follow-up injection.
- If you forget or are unable to return at the scheduled time, ask your doctor, pharmacist, or nurse for advice.
If you have any further questions on the use of this vaccine, ask your doctor, pharmacist, or nurse.
