 The study examined the incidence of interseception among infants in Canada before and after the introduction of rotavirus immunisation programmes, using data from the Canadian Institute for Health Information Discharge Abstract Database. The results showed that annual hospitalisation rates for interseception ranged from 20 to 30 per 100,000 infants, with no evidence of a trend over time. Interseception hospitalisation rates were highest in infants aged 4 to 8 months and lowest in those under 2 months or between 10 and less than 12 months. Males had higher rates than females both overall and within each age group. The rate of interseception hospitalisation after rotavirus vaccine programme introduction was 22.4, 95 per cent CI, 18.3, 27.4, compared to 23.4, 95 per cent CI, 21.5, 25.4, per 100,000 before programme introduction, indicating no significant change in rate after implementation of routine rotavirus immunisation programmes.
