Rotavirus vaccine

An oral vaccine against rotavirus infection, a common cause of diarrhoea and sickness, is given as two doses for babies aged 8 and 12 weeks, alongside their other routine childhood vaccinations.

The vaccine is given as a liquid straight into the baby's mouth for them to swallow.

What is rotavirus?

Rotavirus is a highly infectious stomach bug that typically strikes babies and young children, causing an unpleasant bout of diarrhoea, sometimes with vomiting, tummy ache and fever.

Most children recover at home within a few days, but nearly 1 in 5 will need to see their doctor, and 1 in 10 of these end up in hospital as a result of complications such as extreme dehydration.

Since its introduction into the vaccination programme, the rotavirus vaccine has prevented more than 70% of cases.

The brand name of the rotavirus vaccine used in the UK is Rotarix.

Read the patient information leaflet (PIL) for Rotarix.

Which babies can have the rotavirus vaccination?

Rotavirus vaccination is available routinely on the NHS as part of the childhood vaccination programme for babies aged 8 weeks and 12 weeks.

How does the rotavirus vaccine work?

The vaccine contains a weakened strain of rotavirus. This helps your baby to build up immunity, so that the next time they come into contact with rotavirus they will not get the disease.

How effective is the rotavirus vaccine?

The rotavirus vaccine is very effective and gives good immunity to rotavirus infection. Since the introduction of the rotavirus vaccine in 2013, cases are down by 69%.

The vaccine is given routinely to children in the US and many other countries around the world in Europe, Asia and Latin America.

How safe is the rotavirus vaccine?

There is a lot of evidence showing that the rotavirus vaccine is safe. Rotarix has been used extensively in many countries, including Belgium, Finland, Austria and Canada, for 5 to 6 years and no safety concerns have been raised.

What are the side effects of the rotavirus vaccine?

The vast majority of babies won't have any problems at all after having their rotavirus vaccination, although some babies who have the vaccine may become restless and irritable, and some may develop mild diarrhoea in the days following vaccination.

It is possible for a baby to get rotavirus infection after being vaccinated - but this is uncommon and the illness is usually milder than it would have been if they hadn't been vaccinated.
