Dengue fever remains a significant health concern, especially in tropical countries such as Indonesia. Transmitted through the bite of infected mosquitoes, dengue can affect both children and adults and may lead to serious complications in some cases.
In addition to mosquito control and bite prevention, vaccination can be an important part of a comprehensive dengue prevention strategy. Qdenga® is a dengue vaccine designed to help protect against dengue disease.
But how many doses of Qdenga are needed? How is the vaccine administered? And what should you do if the second dose is delayed?
Here is everything you need to know.
What Is Qdenga?
Qdenga® is a live attenuated tetravalent dengue vaccine. In simple terms, it is designed to help the immune system recognize and respond to the dengue virus.
Dengue has four different serotypes, and Qdenga is designed to provide protection against dengue disease caused by these different types.
Vaccination should be considered as part of a broader dengue prevention strategy. Even after vaccination, it is still important to prevent mosquito bites and maintain a clean environment to reduce mosquito breeding.
Who Can Receive the Qdenga Dengue Vaccine?
Eligibility for Qdenga may depend on factors such as age, medical history, and individual health conditions, as well as the approved recommendations and regulations in the country where the vaccine is administered.
Before vaccination, a doctor or qualified healthcare professional will assess your medical condition and determine whether Qdenga is appropriate for you.
If you are considering the dengue vaccine for yourself or a family member, it is always best to consult a healthcare professional first.
How Many Doses of Qdenga Are Required?
Qdenga is administered as a 2-dose vaccination schedule.
Each dose contains:
0.5 mL per dose
The recommended schedule is:
- First dose: Day or Month 0
- Second dose: Approximately 3 months after the first dose

It is important to complete the recommended vaccination schedule and keep track of your next appointment.
How Is Qdenga Administered?
Qdenga should only be administered by a qualified doctor or trained healthcare professional. The vaccine is given through a subcutaneous injection, which means the injection is administered into the tissue beneath the skin. The vaccine is typically given in the upper arm.
Qdenga should not be self-administered at home. Proper preparation, handling, and administration should always be performed by trained healthcare professionals according to the appropriate medical procedures.
Before vaccination, your healthcare provider may also review your medical history and current health condition.
What Happens If the Second Qdenga Dose Is Delayed?
Missing or delaying a vaccination appointment can happen for many reasons. You may be busy, traveling, unwell, or simply forget the date of your next appointment.
Ideally, the second dose of Qdenga is administered approximately 3 months after the first dose.
If your second dose is delayed, do not panic and do not restart the vaccination schedule on your own.
The best thing to do is to contact your doctor, clinic, or healthcare provider as soon as possible. They can advise you on when the missed or delayed dose should be administered based on the latest medical recommendations and your individual situation.
If Your Second Dose Is Delayed:
- Do not ignore the missed appointment.
- Contact your healthcare provider or vaccination clinic.
- Follow the schedule recommended by your doctor or healthcare professional.
- Do not restart the vaccination schedule unless specifically instructed by a healthcare professional.
If you are unsure when you received your first dose, check your vaccination record or contact the clinic where you received the vaccine.
Does the Second Dose Have to Be Given on the Exact Date?
The second dose is scheduled approximately 3 months after the first dose. However, real-life situations can sometimes cause delays.
If your appointment is missed or postponed, your healthcare provider can advise you on the appropriate next step.
It is important not to make assumptions or change your vaccination schedule without professional medical advice.
If you have a delayed dose, contact your clinic as soon as possible so they can help you continue your vaccination schedule appropriately.
Important Things to Consider Before Receiving Qdenga
Before receiving any vaccine, it is important to inform your doctor or healthcare provider about your medical history and current health condition.
You should discuss conditions such as:
- A history of allergic reactions to vaccines or vaccine ingredients.
- Immune system disorders.
- The use of medications that may affect the immune system.
- Certain medical conditions or ongoing treatments.
- Pregnancy or breastfeeding.
Because Qdenga is a live attenuated vaccine, it may not be suitable for everyone.
This is why a medical consultation and proper health assessment before vaccination are important.
Can You Still Get Dengue After Receiving the Qdenga Vaccine?
Vaccination can help provide protection against dengue, but no vaccine can guarantee 100% protection for every individual in every situation.
For this reason, mosquito bite prevention remains important even after vaccination.
Some simple ways to help protect yourself include:
- Using mosquito repellent as recommended.
- Wearing clothing that helps reduce mosquito bites.
- Keeping your surroundings clean.
- Removing standing water where mosquitoes can breed.
- Regularly cleaning water containers.
- Supporting mosquito control measures in your home and community.
The best approach to dengue prevention includes both vaccination and mosquito bite prevention.
Why Is It Important to Complete the 2-Dose Schedule?
Qdenga is administered as a 2-dose vaccination schedule with an interval of approximately 3 months.
After receiving your first dose, it is important to remember and plan for your second appointment.
Do not assume that the first appointment is the end of your vaccination schedule.
To help you remember your next dose, you can:
- Add the appointment to your phone calendar.
- Set a reminder before your vaccination date.
- Keep your vaccination record in a safe place.
- Ask your clinic whether appointment reminders are available.
Completing your recommended vaccination schedule helps ensure that your vaccination plan is followed appropriately.
Protect Yourself and Your Family Against Dengue
Dengue can affect people of different ages and can occur in many tropical and subtropical regions.
Taking preventive steps can help protect you and your family.
If you are considering the Qdenga dengue vaccine, speak with a qualified doctor or healthcare provider to learn whether it is appropriate for you.
You may want to ask:
- Am I eligible for the Qdenga vaccine?

- When should I return for my second dose?
- What should I do if my second dose is delayed?
