Childhood vaccine
Rotavirus Vaccine
The rotavirus vaccine protects babies against a common cause of severe diarrhoea and vomiting. It is given as drops into the mouth at 8 and 12 weeks.
What it protects against
It protects against rotavirus, a very common infection that causes diarrhoea and vomiting in babies and young children and can lead to dehydration and hospital admission.
Who it's for
Babies, given as two doses of oral drops at 8 and 12 weeks of age. There are age limits for starting and finishing the course.
How it works
It is a live but weakened form of the virus given by mouth, which prompts the gut’s immune system to build protection.
Safety
Safety and side effects
It is safe and well tolerated. Some babies may be a little irritable or have mild diarrhoea afterwards. Because it is a live vaccine, there are specific precautions for babies with a severely weakened immune system.

Answers
Rotavirus Vaccine: frequently asked questions
Why is the rotavirus vaccine given as drops?
Because rotavirus infects the gut, an oral vaccine builds protection where it is needed. The drops are given straight into the baby’s mouth and are usually well accepted.
Is there a time limit for the rotavirus vaccine?
Yes. There are age limits for starting and completing the course, so it is important to give it on time. If your baby is late, ask your GP surgery whether they can still have it.
