A brief history
Rotavirus was identified in 1973 by Ruth Bishop and colleagues studying childhood diarrhoea. Its name refers to its wheel-like appearance under an electron microscope. Before vaccination, infection was almost universal in young children and a major cause of severe gastroenteritis.
How does it spread?
The virus spreads when microscopic traces of infected stool reach the mouth, often through hands, toys or other surfaces. It can survive in the environment and spread readily in households and childcare settings. Handwashing and cleaning remain important alongside vaccination.
Symptoms and possible complications
Rotavirus can cause vomiting, fever and watery diarrhoea. Babies and young children may lose fluid quickly and become dehydrated. Poor feeding, fewer wet nappies or unusual drowsiness need prompt medical advice. The vaccine reduces severe rotavirus illness but does not prevent every cause of vomiting or diarrhoea.
Where it may be relevant
- Infants eligible within the strict routine-programme age limits
- Babies receiving doses through NHS childhood services
Dose schedules
The clinician will select the appropriate licensed schedule after reviewing age, health, previous doses and departure date.
Routine infant course
Eligible infants
Strict upper age limits apply to both doses.
Who may be eligible
- Infants young enough to start and finish the course within current age limits
Who may not be eligible
- Anyone with a confirmed severe allergic reaction to a previous dose or a vaccine ingredient
- People who are acutely unwell with a significant fever may need vaccination deferred
- Pregnancy, breastfeeding, immune suppression and current medicines must be reviewed individually
- Older children and adults are not eligible
- Previous intussusception, severe combined immunodeficiency and some gastrointestinal conditions are contraindications
Potential side effects
- Temporary stomach discomfort, nausea or diarrhoea
- Headache or tiredness
- An allergic reaction is possible but uncommon
Important risks and precautions
- A severe allergic reaction is very rare and requires urgent treatment
- Protection is not absolute, so relevant food, water, bite or exposure precautions remain important
- The exact product and schedule must be confirmed during a clinical assessment
- There is a very small increased risk of intussusception; urgent assessment is needed for severe abdominal pain, repeated vomiting or blood in stool
