The Recommendation and Why It Matters in Singapore
The Health Promotion Board (HPB) recommends annual influenza vaccination for all children from 6 months to under 5 years. Children in this age group are among the most vulnerable to complications from influenza, including febrile seizures, pneumonia, ear infections, and hospitalisation.
In Singapore, influenza circulates year-round unlike temperate countries where there is a single winter flu season. However, Singapore has two peak periods:
Vaccinating 2 to 4 weeks before the peak period gives the best protection. If you are unsure which strain is circulating, your PD or polyclinic can advise on the most relevant time to vaccinate.
Under 6 Months: Cannot Vaccinate, So Protect by Cocooning
Infants under 6 months are too young to receive the influenza vaccine. They are also among the most vulnerable if they contract influenza, as their immune systems are still developing. The protection strategy for this group is called "cocooning."
Cocooning Strategy
All household members and regular close contacts of a newborn under 6 months should receive annual influenza vaccination to create a protective ring around the baby. This includes:
- Both parents
- Siblings
- Grandparents who regularly care for the baby
- Domestic helpers
- Any other regular caregivers
If you are pregnant, receiving influenza vaccination during pregnancy (especially in the second or third trimester) passes some antibody protection to your baby, providing some protection in the early months before they can be vaccinated.
Two Doses for First-Time Recipients
Children under 9 years who are receiving the influenza vaccine for the very first time need two doses, given at least 4 weeks apart. This is because their immune system has never encountered the flu before, and two doses are needed to build adequate protection.
In subsequent years, only one annual dose is required. The vaccine formulation changes each year to match the predicted circulating strains, which is why annual vaccination is important even for children who were vaccinated the previous year.
Children with asthma or chronic conditions: Children with asthma, diabetes, heart conditions, or other chronic diseases are at higher risk of severe influenza complications. Annual vaccination is strongly recommended for this group. Speak to your PD about the optimal timing.
Cost and Where to Get the Flu Vaccine
The influenza vaccine is not part of the NCIP and is not free. It is paid for by parents, though Medisave can be used at approved clinics.
| Venue | Approx Cost Per Dose | Notes |
|---|---|---|
| Polyclinic | S$20 to S$35 | Subsidised for SC/PR; Medisave claimable |
| CHAS GP Clinic | S$25 to S$50 | CHAS subsidies may apply; Medisave claimable |
| Private Paediatrician | S$50 to S$80 | Consultation fee on top; Medisave claimable at approved clinics |

Flu Vaccine Practicalities in Singapore
The flu vaccine is available at polyclinics and CHAS-registered GP clinics across Singapore, as well as private paediatricians. For children under 9 years who are receiving the flu vaccine for the first time, two doses are needed in the first year, given 4 weeks apart. After that first year, one dose annually is sufficient. The flu vaccine is reformulated each year to match the strains expected to circulate, which is why it needs to be given annually even if your child received it the year before. Singapore does not have a single flu season the way northern hemisphere countries do. Two peaks occur each year, typically February to April and again July to September, so the vaccine can be given at any point and ideally 2 to 4 weeks before a peak period. The flu vaccine is MediSave-claimable for eligible patients under the National Adult Immunisation Schedule (NAIS) and related co-payment schemes.
