Influenza, more commonly known as “the flu,” is a contagious respiratory infection that can cause mild to severe illness. In Singapore, flu season does not follow a strict winter cycle, but the Ministry of Health (MOH) aligns vaccination recommendations with global influenza activity by offering both Southern and Northern Hemisphere formulations each year.

With the Northern Hemisphere Flu Vaccine Singapore now available for the 2026 season, many are asking: Should I get this version? What does it cost? Where is it available?

What Is the Northern Hemisphere Flu Vaccine Singapore & Why It Matters

The Northern Hemisphere Flu Vaccine Singapore refers to the vaccine formulation updated for strains expected to circulate in the Northern Hemisphere flu season, which usually peaks from November to February.

Key points:

• Updated twice yearly: The World Health Organization (WHO) convenes experts to recommend flu vaccine composition in February (for the Northern Hemisphere) and September (for the Southern Hemisphere).

• Quadrivalent coverage: Most vaccines in Singapore are quadrivalent, protecting against two influenza A strains and two influenza B strains.

• Local adoption: Singapore, though equatorial, offers both vaccine versions so residents are covered year-round and protected against the most likely circulating strains.

Why People Should Get the Northern Hemisphere Flu Vaccine Singapore

1. Protection against current strains

   
   

   Influenza viruses evolve rapidly. The Northern Hemisphere vaccine reflects the latest WHO-recommended strains, which may differ from those in the Southern Hemisphere version.

2. Prevent serious complications

   
   

   Influenza can lead to pneumonia, hospitalization, and in some cases, death — especially among young children, seniors, and people with chronic conditions.

3. Protect family and community

   
   

   Vaccination not only reduces your personal risk but also limits spread to vulnerable groups, including infants and elderly family members.

4. Reduce healthcare burden

   
   

   By preventing flu outbreaks, vaccination helps reduce clinic visits and hospital admissions during peak season.

According to HealthHub, annual flu vaccination is recommended for everyone aged 6 months and older, with particular emphasis on high-risk groups.

Cost of Northern Hemisphere Flu Vaccine Singapore – Subsidies & Out-of-Pocket

Cost depends on your age, medical condition, and subsidy eligibility.

MediSave can often be used to offset part of the co-payment.

Difference Between Northern & Southern Hemisphere Flu Vaccines

Many ask: Isn’t the flu vaccine the same everywhere? The answer is no.

In some years, the two versions may share identical strains. In other years, they differ in one or more strains based on circulating surveillance. This is why some people in Singapore may receive both vaccines in one calendar year, especially if they travel frequently.

• Common destinations: Japan, South Korea, China, Taiwan, Europe, US.

• Peak holiday season: School breaks, Christmas, New Year, Lunar New Year.
