The Department of Health said the move to vaccinate all babies against the highly infectious bug will mean that thousands of young children will be spared hospital stays and hundreds of thousands of GP visits.
At present, the virus causes 140,000 diarrhoea cases a year in under fives across the UK, and lead to around 14,000 hospital stays.
Vaccination experts believe the immunisation programme will halve the number of vomiting and diarrhoea cases caused by rotavirus and there could be 70% fewer hospital stays as a result.
Children will receive the vaccine, to be given orally as two separate doses of liquid drops, as part of their routine vaccination programme.
