A flu vaccine given as a spray into each nostril, with no injection.

Fear of needles is one of the main reasons children (and many adults) skip their yearly flu vaccine. In Singapore, flu vaccination is available in two forms: the injectable flu vaccine, and a nasal spray flu vaccine for healthy individuals aged 2 to 49. This article explains how the nasal spray works, who it suits, and what to expect. 

What Is the Nasal Spray Flu Vaccine?

The nasal spray flu vaccine is a live attenuated influenza vaccine (LAIV). It contains weakened flu viruses that do not cause influenza illness, but train the immune system to recognise and fight the flu. Because it is given through the nose, it builds protection where flu viruses first enter the body.

It is a trivalent vaccine, covering three flu strains: two influenza A strains (H1N1 and H3N2) and one influenza B strain (B/Victoria lineage).

How Is It Given?

The vaccination involves no injection:

1. You sit comfortably while the doctor or nurse prepares the sprayer.

2. One spray is given into each nostril.

3. Breathe normally — there is no need to inhale deeply or sniff.

4. No recovery time is needed.

Who Can Get the Nasal Spray Flu Vaccine?

It is indicated for healthy individuals aged 2 to 49 years. It may be an option for:

• Children who are afraid of needles

• Parents who want a calmer vaccination experience for their child

• Teenagers and adults who prefer to avoid injections

• Families getting vaccinated together

Who Should Not Take the Nasal Spray Flu Vaccine?

The nasal spray is not suitable for everyone. It is generally not recommended for:

• Children under 2 years old, and adults above 49 years old

• Pregnant women

• People with weakened immune systems, or who live with or care for someone severely immunocompromised

• Anyone who has had a severe allergic reaction to a previous flu vaccine or any of its components

• Children and teenagers on long-term aspirin therapy

• Young children with asthma or a history of wheezing

If you or your child falls into any of these groups, the doctor will usually recommend the injectable flu vaccine instead.

Possible Side Effects of Nasal Spray vs Injectable Flu Vaccine

Both vaccines protect against seasonal flu. The doctor will recommend the option that fits your age and health.

Nasal Spray Flu Vaccine Side Effects

Most side effects are mild and short-lived:

• Runny or stuffy nose

• Sore throat (more common in adults)

• Mild fever in young children

• Headache or tiredness

Why Get a Flu Vaccine Every Year in Singapore?

Singapore has flu activity throughout the year, and the virus spreads easily in schools, offices and crowded places. Annual flu vaccination reduces your risk of infection, lowers the chance of serious complications, and helps protect those around you — including babies, older adults and people with chronic conditions.

Flu Strains Covered for the 2026/27 Season

As of October 2026, the nasal spray flu vaccine for the 2026/27 season covers:

Flu viruses change from year to year, so the strains in the vaccine are updated each season to match those expected to circulate.
