E.5 End points |
E.5.1 | Primary end point(s) |
The incidence of cases with vaccine preventable outcome (VPO) reported during the surveillance period; VPO is all moderate/ severe diarrheal cases in which LT , LT/ heat stable toxin (ST) or ST toxins (ETEC) are detected by either PCR or DNA hybridisation (and no co-pathogen is detected) from diarrheal stool samples that are collected during the first diarrheal episode |
