Needle-Free Flu Protection: The Intranasal Flu Vaccine is Now Available in Singapore

Influenza continues to be one of the most common viral infections globally — and yearly vaccination remains the most effective way to prevent severe illness, hospitalisation, and community spread. At District Family Clinics, we now offer a needle-free intranasal flu vaccine, giving patients a more comfortable and convenient option.

Why Get a Flu Vaccine?

Flu vaccination offers multiple health benefits:

• Reduces risk of infection

• Lowers severity of illness if you do get the flu

• Prevents complications such as pneumonia

• Reduces hospitalisations and time off work

• Helps protect vulnerable individuals through community immunity

Vaccines work by training your immune system to produce protective antibodies, so your body is ready when exposed to the virus.

Intranasal vs Intramuscular (Injection) Flu Vaccines

Traditionally, flu vaccines are given by injection. However, the newer intranasal vaccine offers comparable protection with several added advantages.

Intranasal Vaccine (Needle-Free)

• Delivered through the nostrils

• Activates mucosal immunity, the body’s first line of defence

• Produces secretory IgA antibodies right at the virus entry point

• Shows strong immune response and good tolerability in clinical studies

• Pain-free and ideal for people who dislike injections

Injection (IM) Vaccine

• Stimulates a strong systemic (bloodstream) immune response

• Long-standing and widely used option

• Suitable for most adults and seniors

Which Works Better?

Studies and meta-analyses suggest that when well-designed, intranasal flu vaccines can be as effective as — or sometimes more effective than — injections. Singapore’s HSA has approved the first intranasal option, FluMist Trivalent, confirming its safety and reliability.
