The cost varies depending on eligibility for influenza vaccination subsidies. CHAS, Merdeka Generation, Pioneer Generation, and eligible MediSave holders may receive subsidies for flu vaccination. CDC vouchers, MBS@GOV, and Baby Bonus may also be used. We also work closely with insurance and corporate partners to ensure accessibility to flu vaccinations. You may contact us for more information.

No, fasting is not required before receiving the flu vaccine. You may eat and drink normally before your vaccination.

In fact, having a regular meal beforehand can help reduce the chances of dizziness or feeling faint, especially in children, elderly individuals, or those who are sensitive to injections.

However, if you are feeling unwell, have a high fever, or have concerns about allergies or previous vaccine reactions, it is best to inform your doctor before vaccination so suitability can be assessed.

No. If you are currently down with influenza or have an active flu infection, flu vaccination should be postponed.

If you are acutely unwell with fever and flu symptoms, your immune system is already fighting an infection. Receiving the flu vaccine at this time will not help treat the current illness and may make it harder to distinguish vaccine side effects from worsening symptoms.

It is recommended to wait until you have fully recovered before receiving the flu vaccine. Once you are well, vaccination can help protect you from other circulating influenza strains and reduce the risk of future infections.

If you are unsure whether your symptoms are due to influenza or another illness, you may contact us to assess your condition and advise on the appropriate timing for vaccination.

It takes approximately 2 weeks after vaccination for your body to develop adequate immunity.

Protection typically lasts about one year, which is why annual flu vaccination is recommended.

Additionally, influenza viruses change over time, and immunity decreases. Annual vaccination ensures protection against the most current circulating strains.

Yes. The flu vaccine can usually be given together with other vaccines, including COVID-19 vaccines, subject to medical assessment.

Common side effects include:

• Mild pain or swelling at the injection site

• Low-grade fever

• Fatigue or muscle aches

Serious side effects are rare.

No. The flu vaccine cannot cause influenza. Some people may experience mild flu-like symptoms as the immune system responds, but this is not flu infection.

Yes. Flu vaccination is safe and recommended during pregnancy and helps protect both mother and baby.

Yes. Children aged 6 months and above can receive the flu vaccine. Vaccination helps reduce school-related transmission and serious complications in young children.

Please inform us if you:

• Are allergic to flu vaccine or any of the other ingredients of the flu vaccine

• Have a history of Guillain-Barré Syndrome (a rare condition where the body’s immune system attacks the nerves)

• Have a severe allergy to eggs

Our clinic doctor will assess suitability before administration.

The flu vaccine does not cause influenza. However, some people may experience mild flu-like symptoms after vaccination because the body’s immune system is responding to the vaccine.

After vaccination, your immune system recognises the inactivated virus particles (or viral proteins) and begins producing antibodies. This immune response can temporarily cause symptoms such as:

• Mild fever

• Fatigue

• Muscle aches

• Headache

These symptoms are not the flu. They are a sign that your body is building protection against influenza and usually resolve within 1–3 days.

In contrast, actual influenza infection typically causes more severe symptoms, lasts longer, and may lead to complications such as pneumonia or hospitalisation. If symptoms persist beyond a few days or worsen significantly, medical review is recommended.

Flu vaccination can be done any time of the year in Singapore due to year-round influenza circulation. Early vaccination is recommended before:

• Peak flu periods

• Overseas travel

• School terms or major gatherings

Yes. Influenza vaccines used in Singapore are approved by the Health Sciences Authority (HSA) and have been safely administered worldwide for many years. Most side effects are mild and temporary, such as soreness at the injection site or low-grade fever.

Flu vaccine effectiveness varies yearly depending on circulating strains, but vaccination significantly reduces the risk of severe illness, complications, and hospitalisation, even if infection occurs.
