Common name:

RV1, rotavirus vaccine

Protects against rotavirus.



Rotarix® is an oral vaccine given at 6 weeks and 3 months of age. 

For safety reasons, the first dose of Rotarix can only be given to babies younger than 15 weeks of age. The last dose of Rotarix can only be given to babies younger than 25 weeks of age.

The vaccine contains live weakened rotavirus.

In countries like New Zealand, a course of either Rotarix vaccine will protect around 8 babies in 10 from severe rotavirus infection and needing to be admitted to hospital because of rotavirus infection.

Responses to vaccine

Rotarix (RV1)

Responses to vaccine

Common responses

  • Mild diarrhoea or vomiting
  • Mild abdominal pain

Rare responses

  • Intussusception (bowel obstruction)

As with any medicine, very rarely, severe allergic reactions occur following immunisation. For this reason we ask people to wait 20 minutes after receiving vaccines.

In Depth

Vaccine type: liveiattenuated virus vaccine (oral)

Schedule and administration

  • Rotarix is given to babies as two oral doses at the 6 week and 3 month immunisation visits.
  • Rotarix is given orally, only, and should never be injected.
  • The first dose must be given before 15 weeks of age (up to and including 14 weeks 6 days old). If dose one not given by this age, then no doses can be given. Subsequent doses of Rotarix must not be given once a baby is aged 25 weeks or older (latest is 24 weeks and 6 days).
  • Rotarix can be administered concurrently with other vaccines, including all the National Immunisation Schedule vaccines.
  • It is recommended to give Rotarix before injected vaccines as the sugar solution helps to mitigate any pain caused by these injections.
  • A dose does not have to be re-administered if the infant spits it out, regurgitates or vomits immediately after administration.
  • Infants can have breast milk, formula or food before and after immunisation.

Special considerations

Further medical advice should be sought for any baby suspected or known to have a weakened immune system, for example due to HIV/AIDS or treatment with long term steroids, or any baby who has cancer or who is undergoing treatment for cancer.

Catch-up doses

Catch-up of the first Rotarix dose can only be given to babies younger than 15 weeks of age, i.e. up to and including the age of 14 weeks 6 days. If the first dose is not given BEFORE 15 weeks of age, NO doses can be given.

A second dose of Rotarix can only be given to babies younger than 25 weeks of age, i.e. up to and including the age of 24 weeks 6 days. NO Rotarix doses can be given to babies aged 25 weeks or older.

Special vaccine storage and preparation considerations

No special considerations, store as per cold chain between +2°C to +8°C.

Vaccine safety

One or two babies in 10 may have mild vomiting or diarrhoea during the 7 days after immunisation. However, studies suggest these symptoms may be unrelated to rotavirus vaccine because around the same number of babies who received a placebo liquid not containing rotavirus also developed these symptoms. The weakened rotavirus from the vaccines may be found in stools for up to 28 days after the first immunisation and up to 15 days after the second dose. However, after changing nappies caregivers only need to follow standard hygiene measures, i.e. wash their hands using soap and water and dry them well, or use liquid hand gel.

The risk of intussusception after a rotavirus vaccine is very small and the risks from rotavirus infection are much larger. Generally, the benefits of immunisation against rotavirus are considered to exceed the risk of intussusception.

Although the risk of intussusception after rotavirus immunisation is very small, it is recommended that parents seek medical advice if their baby develops intermittent crying/screaming episodes, pull their knees towards their chest and vomit, or develop pink or red coloured jelly-like stools.

Vaccine should not be given to any baby who:

  • Has severe combined immunodeficiency (SCIDS)
  • Has previously had intussusception and with condition that predisposes the infant to intussusception
  • Had a severe allergic reaction (anaphylaxis) to any component in the vaccine or to a previous doses of the vaccine

Rotarix should be postponed for any baby with moderate to severe fever, vomiting or diarrhoea.

Babies in hospital, including those in neonatal units, can be immunised. The vaccine can be administered to a baby who lives with someone who is immunocompromised or receiving immunosuppressive therapy. After changing nappies caregivers are recommended to follow standard hygiene measures, i.e. wash their hands using soap and water and dry them well, or use liquid hand gel. 

Vaccine effectiveness

In countries like New Zealand, a course of Rotarix vaccines will protect around 8 babies in 10 from severe rotavirus infection and needing to be admitted to hospital because of rotavirus infection

here has been an over 90% reduction in rotavirus hospitalisations in industrialised and resource-deprived countries. As of January 2015, at least 75 countries worldwide had implemented rotavirus vaccination as part of the national immunisation schedule. 

Prior to the introduction of rotavirus vaccine to the New Zealand Immunisation Schedule in 2014, 500–800 hospital admissions in children aged under 5 years annually were related to rotavirus gastroenteritis in the years 2010–2014. In 2015, after the introduction of rotavirus vaccine, the annual rate of rotavirus hospital admissions fell to less than 100.
