For years, respiratory syncytial virus (RSV) has been a daunting shadow over the first two years of a child’s life. In Singapore, where the virus doesn’t follow the seasonal patterns seen in temperate climates but persists year-round, the battle to protect newborns has entered a new phase. While the introduction of maternal vaccines marked a milestone, the current landscape reveals a critical gap between medical availability and actual public uptake.
The challenge is clear: while the science proves that maternal vaccination can slash infant hospitalizations by over 80%—as seen in data from the United Kingdom—local hospital admission rates remain stubbornly stable. The question now is not whether the vaccines work, but how healthcare systems can bridge the gap to ensure every newborn starts life with a shield of antibodies.
The “Uptake Gap”: Why Maternal Vaccination Isn’t Yet a Silver Bullet
Medical professionals are observing a frustrating paradox. Awareness is rising, and more expectant mothers are opting for the jab between 32 and 36 weeks of pregnancy, yet the numbers aren’t high enough to create “herd-like” protection or a measurable dip in pediatric ward admissions.
Several friction points continue to hinder universal adoption. Cost remains a primary hurdle; with a single dose ranging from S$250 to S$350 and no current government subsidies for the maternal RSV jab, many parents view it as an optional luxury rather than a medical necessity. When coupled with lingering concerns about vaccine safety and the duration of protection, the “wait and see” approach becomes common.
RSV isn’t just a “bad cold.” Recent research from Singapore General Hospital indicates that patients hospitalized with RSV can face long-term health complications that are comparable to, or even exceed, those seen after influenza or Omicron COVID-19 infections.
The Shift Toward a Multi-Layered Defense Strategy
The future of RSV prevention is moving away from a single-point solution toward a “layered” approach. We are seeing a transition from relying solely on maternal antibodies to a combination of maternal and pediatric interventions.
The Rise of Infant-Specific Immunization
A significant trend is the approval of RSV vaccines specifically for infants up to 24 months of age. This provides a critical safety net for babies whose mothers were unable or chose not to be vaccinated during pregnancy. By diversifying the timing and target of the vaccine, healthcare providers can capture a wider percentage of the vulnerable population.
Integration into Routine Antenatal Care
Leading institutions, such as the National University Hospital (NUH), are already shifting the conversation. Rather than treating the RSV vaccine as an “add-on,” it is becoming a standard part of routine antenatal discussions. This “shared decision-making” model helps demystify the vaccine, allowing doctors to address safety concerns in real-time before the 32-week window closes.

Predicting the Next Wave: Subsidies and Policy Shifts
As the burden of RSV-related hospitalizations continues to strain pediatric intensive care units, the conversation regarding subsidies is likely to intensify. Historically, vaccines are added to national immunization schedules based on disease burden and cost-effectiveness.
If data continues to show that high uptake significantly reduces the need for expensive hospital stays and intensive care, there will be a strong economic argument for the Ministry of Health to include maternal RSV vaccination in subsidized schedules. A shift toward subsidy would likely trigger a rapid spike in uptake, potentially mirroring the success seen in the UK model.
Start the conversation about RSV protection with your OB/GYN during your second-trimester scans. Because the window for maternal vaccination is narrow (typically 32–36 weeks), having the information early prevents last-minute stress and allows you to budget for the cost if subsidies are not available.
Comparing Global Outcomes: The UK Benchmark
Singapore’s journey reflects a global trend in pediatric medicine. In the UK, where maternal RSV vaccination has been more widely integrated, the results are staggering: a reduction in infant hospital admissions by more than 80%. In some cases, when administered earlier in pregnancy, protection reaches 85%.
The disparity between these results and the current stability of Singapore’s admission rates highlights a fundamental truth in public health: the efficacy of a drug is irrelevant if the delivery system (access and affordability) is flawed. The trend for the next few years will likely be an aggressive push to align local delivery systems with these global benchmarks.

Frequently Asked Questions
Q: When is the best time for a pregnant woman to receive the RSV vaccine?
A: In Singapore, the vaccine (Abrysvo) is typically administered between 32 and 36 weeks of pregnancy to ensure maximum antibody transfer to the newborn.
Q: Is the RSV vaccine subsidized in Singapore?
A: Currently, the maternal RSV vaccine is not part of the National Adult or Childhood Immunisation Schedules and is not subsidized, costing between S$250 and S$350.
Q: Can infants be vaccinated if the mother wasn’t?
A: Yes. Newer vaccines approved for children up to 24 months of age provide an alternative path for protection.
Q: Does the vaccine prevent all RSV infections?
A: While it may not prevent every single infection, data suggests it significantly reduces the severity of the illness, making hospitalisation much less likely.
