The impact of the rotavirus vaccine on diarrhoea, five years following national introduction in Fiji

Fig. 1. Incidence rate ratios (post-rotavirus vaccine vs. pre-rotavirus vaccine introduction) for all-cause diarrhoea and all cause admissions and rotavirus diarrhoea CWMH admissions, Savusavu inpatients and Savusavu outpatients. An incidence rate ratio above one (the black line) represents an increase in incidence rate from the pre-rotavirus vaccine period and an incidence rate ratio below one represents a decrease in incidence rate from the pre-rotavirus vaccine period.
