Singapore's Communicable Diseases Agency reported on 4 September 2026 an increase in flu cases, though infections are not more severe than usual. Vaccination is specifically recommended for seniors aged 65+, children 6 months to under 5 years, and people with underlying medical conditions. The 2026 seasonal flu vaccine is available at CHAS GP clinics, polyclinics and participating pharmacies (for eligible adults 18+). Work pass holders can also ask their clinic about getting vaccinated, but should check the cost first since government subsidies mainly apply to citizens and PRs.
