Getting vaccinated against influenza helps strengthen your immunity against evolving flu strains. In Singapore, flu season typically peaks twice a year — between November to February (Northern Hemisphere) and May to July (Southern Hemisphere). As the vaccine takes about two weeks to build full protection, it’s best to get your flu shot early.
CHAS subsidies are available for vaccinations recommended under Ministry of Health’s NCIS or NAIS
Eligible Singapore Citizens and Permanent Residents may use Medisave to cover any remaining cost of Influenza vaccination.
Up to $500 or $700 per year, depending on eligibility, for individuals in high-risk groups.



There are 3 major brands of Influenza vaccine – Vaxigrip Tetra (Sanofi), Fluarix Tetra (GSK), Influvac Tetra (Abbott). They are all quadrivalent vaccines (covers 4 strains), therefore the name “Tetra.”
Flu vaccine is for all! From as young as 6 months to the elderly! They are given annually and depending on the prediction of the next predominant strain of the flu season, either the Northern Hemisphere or the Southern Hemisphere will be administered. They are safe and effective in the prevention of Influenza infection.
The body usually takes 2 weeks to manufacture the antibodies after the flu shot.
It’s recommended to take the shot on an annual basis, you may take it at any time of the year, as long as it’s due (i.e. > 1 year since your last flu vaccine)
No, there is no need to avoid any food, shower or exercise after vaccination. Do hydrate and rest your arm if it gets sore!
You may take simple paracetamol if you have any mild side effects after the shot for soreness in the arm or mild body aches!

As the vibrant city-state of Singapore gears up for its annual bout with the flu season, the importance of vaccination takes center stage. In the quest for robust community health, understanding the nuances of flu vaccination becomes crucial.
Influenza, commonly known as the flu, is a highly contagious viral infection that impacts millions of people worldwide annually. In Singapore, the flu season poses a significant health challenge, making flu vaccination an essential preventive measure.
Singapore, with its tropical climate, may not experience the stereotypical seasons, but the flu virus certainly knows no boundaries. The flu season typically peaks between December and February, creating a window of vulnerability for the unprepared. This is where the role of flu vaccination comes into play as a proactive defense strategy.
Vaccines such as the influenza vaccine is recommended for ALL ages, even healthy young persons, because it saves lives and reduces morbidity. They aren’t just done when traveling overseas, which is a popular misconception. They can also play a role in cancer prevention (cervical cancer and liver cancer).
Did you know that with effect from 1st November 2020, all Singapore Citizens (SCs) and Permanent Residents (PRs) can receive free or heavily subsidised vaccinations at private CHAS GP clinics under the National Adult/Child Immunisation Schedule (NAIS/NCIS)?

Almost all vaccinations under the National Child Immunisation Schedule (NCIS) are fully-subsidised (i.e. $0) while recommended adult vaccinations under the National Adult Immunisation Schedule (NAIS) have subsidies of between $35 to $125.
Starting from 1st November 2020, you can also use your MediSave to pay for the co-payment cost of the recommended vaccines. Patients who are 60 years old and above can also tap on Flexi-MediSave.
Under Healthier SG, eligible individuals with selected health conditions (e.g. Diabetes , kidney disease, lung conditions, etc., or if they are 65 and above) can receive the influenza vaccination for free at our clinics if they have chosen to be enrolled in.
See the vaccination fees table for after-subsidy-fees for Recommended Adult Vaccinations under the NAIS. The fees are also fully Medisave-claimable.
The primary goal of flu vaccination is to shield individuals from the potential ravages of the influenza virus. By stimulating the immune system to recognize and combat the virus, the vaccine significantly reduces the risk of falling prey to the flu.
Opting for flu vaccination isn't just about personal protection; it's a collective endeavour. When individuals get vaccinated, they contribute to the development of community immunity, safeguarding those who may be more susceptible to severe flu-related complications.
Influenza isn't just a common cold; it can lead to severe complications such as pneumonia, especially in vulnerable populations. Vaccination serves as a preventive measure, curbing the likelihood of these complications and mitigating the strain on healthcare resources.
Getting vaccinated before the flu season peaks is a strategic move. By doing so, individuals provide their immune systems ample time to build the necessary defenses, ensuring they're well-equipped when exposed to potential flu viruses.
The influenza virus is notorious for its ability to mutate. Consequently, the flu vaccine undergoes an annual update to align with prevalent strains. This ensures that individuals receive the most effective protection against the evolving nature of the virus.


Certain groups are more susceptible to severe flu complications and are strongly encouraged to get vaccinated. These include:
The general public is also encouraged to receive annual flu vaccinations to maintain community health and prevent outbreaks.
Timing is crucial for flu vaccination; it is best to get vaccinated before the flu season starts to ensure optimal protection. Besides vaccination, adopting good hygiene practices can further reduce the risk of flu transmission, including:
Wash hands frequently with soap and water.
Especially in crowded places or when feeling unwell.
Minimise exposure to potential sources of infection.
Recognizing flu symptoms early and seeking medical help can prevent complications and the spread of the virus.


Singapore, known for its commitment to public health, ensures that flu vaccinations are accessible across the island. From healthcare providers and clinics to workplace vaccination programs, the nation’s infrastructure is geared towards making vaccination a convenient and streamlined process.

In the dynamic landscape of Singapore’s urban life, where health is paramount, opting for flu vaccination becomes a proactive choice. It’s not just a shot in the arm against the flu; it’s a commitment to personal well-being and a collective responsibility towards community health.

The positive impact of flu vaccination is evident in various case studies and statistical data. For instance, higher vaccination rates correlate with lower incidences of flu-related hospitalizations. The public health benefits are substantial, contributing to overall community health and reducing the burden on healthcare systems.
Flu vaccination is a critical measure in protecting against influenza and its complications. By getting vaccinated, you not only safeguard your health but also contribute to the well-being of the community. As flu season approaches, take proactive steps to get vaccinated and practice preventive measures to navigate the season effectively.
