Rotavirus

Can a child get rotavirus after being vaccinated?

Yes. Children may get infected with rotavirus more than once even those who are vaccinated. The immunity developed from natural infection with rotavirus or via rotavirus vaccination does not provide full protection from future infections. However, children who are vaccinated are less likely to get sick from rotavirus as compared to those who are not vaccinated. At least 90% of vaccinated children are protected from severe rotavirus diarrhoea.

How is rotavirus transmitted?

Rotavirus is among the most common infectious diseases affecting young children. It typically spreads between patients and care takers who don’t maintain strict hand hygiene, leading to vicious cycle of recurring infection within a family.

Rotavirus Symptoms

Rotavirus symptoms typically begin about 2 days after exposure to the virus, which can persist for 3 to 8 days.

• Severe watery diarrhoea
• Vomiting
• Fever
• Stomach pain
• Dehydration
• Reduced urination
• Dry mouth and throat
• Dizziness when standing
• Crying with little to no tears
• Unusual sleepiness or irritability

Some children may only experience milder symptoms, while others may develop severe symptoms and complications such as severe diarrhoea or rotavirus gastroenteritis.

Rotavirus Treatment

There is no specific medication to treat rotavirus infection, but your healthcare provider may recommend treatments to manage the symptoms.

• Stay Hydrated: Drinking plenty of fluids is the most effective way to combat dehydration.
• Get Medical Attention for Severe Dehydration: If dehydration becomes severe, hospitalisation may be necessary and intravenous (IV) fluids are administered directly into the veins to quickly restore hydration levels.

Rotavirus Vaccine Schedule in Malaysia

Currently, there are two rotavirus vaccines licensed in Malaysia namely RotaTeq, which is given in 3 doses at ages 2,4,6 months and Rotarix, which is given in 2 doses at ages 2 & 4 months. These vaccines are given orally instead of intramuscular injection. All doses of rotavirus vaccine should be completed before the child turns 8 months old.
