Should I Give My Baby the Rotavirus Vaccine?
Rotavirus is the most common cause of severe diarrhoea in young children. There is a strict age deadline for the vaccine and a strong recommendation from Singapore paediatricians.
What Rotavirus Is and What the Vaccine Prevents
Rotavirus is the most common cause of severe gastroenteritis (diarrhoea and vomiting) in infants and young children worldwide. Before the vaccine was introduced, almost every child got rotavirus at least once before age 5.
Why Rotavirus Is Particularly Concerning
- Extremely contagious: spreads via hands, surfaces, and contaminated water
- Can cause severe dehydration in babies, sometimes requiring hospitalisation and IV fluids
- Incubation period of just 48 hours; symptoms include profuse watery diarrhoea, vomiting, and fever
- No specific antiviral treatment: management is supportive (fluids and rest)
- Singapore's childcare centres, where many infants spend full days, are high-transmission environments
The rotavirus vaccine is approximately 85 to 98% effective against severe rotavirus disease. It significantly reduces the risk of hospitalisation for gastroenteritis in vaccinated children.
Vaccine Options: Rotarix vs RotaTeq
Two rotavirus vaccines are available in Singapore. Both are oral (drops, not injections) and are equally effective. Your PD may offer one or the other based on their clinic's supply.
| Feature | Rotarix (GSK) | RotaTeq (Merck) |
|---|---|---|
| Number of doses | 2 doses | 3 doses |
| First dose timing | From 6 weeks; must be before 12 weeks | From 6 weeks; must be before 12 weeks |
| Schedule | At 2 months and 4 months | At 2, 4, and 6 months |
| Final dose deadline | Before 24 weeks (6 months) | Before 32 weeks (8 months) |
| Route | Oral drops | Oral drops |
Critical deadline: The first dose of any rotavirus vaccine must be given before 15 weeks of age (just under 4 months). The final dose must be completed before the deadlines above. If these windows are missed, the vaccine cannot be given due to an increased risk of intussusception (a rare but serious bowel obstruction) when the vaccine is given to older infants. There are no exceptions to this age rule.
Cost in Singapore
Rotavirus vaccine is not part of the NCIP and is not free. It is available at private paediatric clinics. The cost varies by clinic and brand.
| Vaccine | Cost Per Dose | Total Series Cost | Medisave Claimable |
|---|---|---|---|
| Rotarix (2 doses) | S$200 to S$400 | S$400 to S$800 | Yes (at approved clinics) |
| RotaTeq (3 doses) | S$180 to S$350 | S$540 to S$1,050 | Yes (at approved clinics) |
The S$4,000 Medisave Grant for Newborns can cover a significant portion of rotavirus vaccine costs at approved clinics. Ask your PD if they are Medisave-approved for this vaccine.
Strong Recommendation from Singapore Paediatricians
Most Singapore paediatricians strongly recommend the rotavirus vaccine for all infants. Key reasons in the Singapore context:
- Many Singapore infants attend infant care from 2 to 3 months, where the risk of rotavirus transmission among babies is high
- Singapore's weather supports year-round rotavirus circulation
- Hospitalisation for severe gastroenteritis in infants is distressing and disruptive; the vaccine nearly eliminates this risk
- The vaccine is safe and well-tolerated; only mild, temporary loose stools are typical
- The cost is justified given the risk reduction, especially for families with children in group care
Timing is everything: Discuss the rotavirus vaccine with your PD at your 2-month well-baby visit (or earlier). Because the first dose window opens at 6 weeks and closes at 15 weeks, you have a narrow window to start. Do not delay this conversation.
