A systematic review and meta-analysis of Penner serotype prevalence of Campylobacter jejuni in low- and middle-income countries.

The results of this review suggest that an octavalent vaccine could provide up to 66.9% coverage of typable strains worldwide, and 56.8-69.0% regionally. This review also highlights the paucity of available data on capsules in LMICs; more testing is needed to inform vaccine development efforts.
