Rotavirus is the most common cause of childhood diarrhoea worldwide. Infants and young children in crèches and children's hospitals are most often infected. Susceptibility is greatest between 6 and 24 months of age. Usually by three years of age most people have been infected and have acquired immunity to the virus. The virus is also a common cause of diarrhoea in the elderly living in long-term care facilities and homes for older adults.

Rotarix™ vaccine was introduced in Ireland in December 2016 for all babies born from 1st October 2016 onwards. Rotarix™ is a live attenuated monovalent vaccine. Vaccine is administered orally in two doses at 2 months and 4 months. Both doses must be administered by 8 months old. Further information on rotavirus vaccine is available on the HSE website
