How is rotavirus spread?

Rotavirus is spread in poo (faeces) through hand-to-mouth contact and can be picked up from surfaces such as toys, hands or dirty nappies. It can also be spread through the air by sneezing and coughing.

It's most often spread when someone who is infected does not wash their hands properly after going to the toilet.

Washing hands and keeping surfaces clean can help to reduce the spread of the virus, but will never completely stop it. Vaccination is a much more effective way of protecting babies from getting infected.

How is the rotavirus vaccine given?

Rotavirus vaccine is given orally as a liquid straight into the baby's mouth.

What if my baby spits out the vaccine or vomits immediately after having it?

The  oral vaccine will be given again. Don't worry about overdosing. Even if some of the vaccine went in first time, there's no harm in having two doses at the same time.

When will the rotavirus oral vaccine be given to babies?

The first dose will be given at eight weeks, and the second dose at 12 weeks.

What if my baby misses the first dose of rotavirus oral vaccine?

They can have it later, up to 15 weeks. If they miss the second dose of rotavirus oral vaccine (normally given at 12 weeks), they can have that later, up to 24 weeks old.

Why can't older babies have the rotavirus vaccination?

The oral vaccine is only licensed for infants up to 24 weeks of age. Older children have very often already had a rotavirus infection, so there is no point in vaccinating them.

Also, as they get older, some babies get a condition that causes a blockage in their lower gut, called intussusception, though this is rare. It's extremely rare before 12 weeks, and most cases happen between five months and a year old.

There's a very small chance (around 5 in every 100,000 babies vaccinated) that the first dose of the vaccine might also cause this blockage to develop.

To reduce the risk of this happening, the first dose of the vaccine should not be given to babies older than 15 weeks of age.

Which babies should have the rotavirus vaccination?

The rotavirus oral vaccine is a routine childhood vaccination for babies aged two and three months.

Your baby needs two rotavirus vaccinations at least a month apart to be fully protected. If they miss one of the vaccinations, the first one can be given a month later, at 12 weeks, and the second dose a month later, at 16 weeks, if necessary.

The rotavirus vaccination is only suitable for young babies. The first dose cannot be given any later than 15 weeks and the second dose no later than 24 weeks. Babies can only have the second dose if they had their first dose before 15 weeks.

Which babies shouldn't have the rotavirus vaccination?

The rotavirus vaccine should not be given to babies who: 

  • are seriously ill with either diarrhoea and vomiting, or a fever on the day of the appointment. It's best to postpone the vaccination until your baby has recovered. There's no need to delay rotavirus vaccination if your baby is well enough to have their routine childhood vaccinations
  • have reacted very badly (including with an anaphylactic reaction) to a previous dose of the vaccine, or to any of the substances that go into the vaccine
  • are older than 24 weeks of age

Speak to your GP first if your baby has any of the following long term conditions:

  • a history of intussusception (a disorder of the intestines)
  • severe combined immunodeficiency (SCID) disorder – a rare genetic disease that makes babies very vulnerable to infection
  • fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency – which are all rare inherited disorders

Is the rotavirus oral vaccine made in eggs? Does this affect children with allergies?

This vaccine is not made in eggs and should be perfectly safe for babies with general allergies, although any baby with a history of allergy to the vaccine or constituents of the vaccine should not be vaccinated.

Does the rotavirus oral vaccine contain thiomersal?

No. None of the routine childhood vaccines contains Thiomersal.

What if my baby is ill on the day the vaccination is due?

There's no reason to postpone the appointment, unless your baby is seriously ill with a fever or diarrhoea and vomiting. If your baby is well enough to have the other routine vaccinations, they can have the rotavirus vaccine.

Here are the top vaccination tips for parents.

How long will the rotavirus vaccination protect my baby for?

We don't know for sure, but clinical trials have shown that two doses of the vaccine protect for several years.

Can I opt out if I wish?

Yes. No one can force you to have your baby vaccinated against rotavirus infection, but the evidence suggests that it's in the best interests of your child.

Read more about this and the other top questions that parents have about baby vaccinations.

Is it ok to breastfeed my baby after the vaccination?

Yes. There are no problems linked with breastfeeding babies who have recently had the rotavirus oral vaccine.

Do I need to take special care when changing my baby's nappy after rotavirus vaccination?

Yes. Because the vaccine is given to your baby by mouth, it's possible that the virus in the vaccine will pass through your baby's gut and be picked up by whoever changes their nappy.

The vaccine contains only a weakened form of the rotavirus, so traces of it in a baby's nappy won't harm healthy people.

However, it could pose a risk for people with a severely weak immune system (such as anyone having chemotherapy).

As a precaution, anyone in close contact with recently vaccinated babies should take special care with personal hygiene for two weeks following vaccination, including washing their hands carefully after changing the baby's nappy.

Will the rotavirus vaccination stop my baby getting any sickness and diarrhoea?

No. Rotavirus isn't the only cause of sickness and diarrhoea in babies, so some may still get unwell. However, the vaccine will stop about 8 out of 10 babies that have the vaccine getting severe vomiting and diarrhoea caused by rotavirus.

The more babies that have the vaccine, the more difficult it will be for the virus to spread.

My baby was premature. When should they have the rotavirus vaccination?

As with all vaccinations, the schedule should be followed from the actual date of birth, not from the date your baby was due. Therefore, your baby should have the rotavirus vaccine at 8 weeks and 12 weeks, no matter how premature they were.

Read about vaccinations for premature babies.

Can my baby receive the rotavirus oral vaccine at the same time as other vaccines?

It's perfectly safe for your baby to have the rotavirus oral vaccine at the same time as other childhood vaccines, such as the 5-in-1 and pneumococcal vaccines.
