Flu Cases Climb in Singapore: Health Authorities Push Vaccination for Seniors, Young Kids, and At-Risk Residents

Singapore – Singapore is seeing more flu cases, and health authorities want vulnerable residents protected before things get worse. The Communicable Diseases Agency (CDA) is urging people at higher risk of severe infection to get their flu shot without delay.

According to a news report, the CDA issued the advisory on Friday, September 4, 2026. The agency confirmed influenza is on the rise, though there is no sign that infections are more severe than usual.

Who Should Get Vaccinated

The CDA is encouraging those most at risk to receive the 2026 Southern Hemisphere (SH) flu vaccine if they haven’t already. This group includes:

  • Seniors aged 65 and above
  • Children aged six months to under five years
  • People with underlying medical conditions

If you or a family member falls into any of these groups, this advisory is worth acting on.

Where and How to Get Your Shot

There’s good news on supply. The CDA says there is enough of the 2026 SH vaccine to go around, so you can approach your healthcare provider directly. You can book an appointment through:

  • vaccine.gov.sg/flu or your nearest polyclinic
  • Participating CHAS GP clinics
  • Retail pharmacies (for adults aged 18 and above)
  • Your enrolled clinic, if you’re a Healthier SG member

A Delay in the Next Vaccine Batch

Here’s something to plan around. The 2026–2027 Northern Hemisphere (NH) flu vaccine, usually available by end-September, is now expected in early to mid-October 2026 — about two weeks later than normal.

The hold-up is an industry-wide delay in developing the new vaccine, which carries a two-strain change from the current SH version. That change is meant to better match the viruses expected to spread in the coming season.

What This Means for You

The Expert Committee on Immunisation has shared clear guidance to help you decide your next step:

  • Not yet vaccinated? If you’re in a vulnerable group, consider waiting for the NH vaccine, as it’s expected to offer better protection.
  • Want protection now? You can get the SH vaccine today, but still plan to get the NH vaccine later, with at least eight weeks between doses.
  • Already had the SH shot? Wait for the NH vaccine as your next dose, keeping a minimum eight-week gap.

Whatever your situation, a quick chat with your doctor can help you time it right and stay protected through the season ahead.
