Differences in timeliness, completeness and drop-out rates of MMRV and DTP containing vaccines among Ultra-Orthodox Jews and others in a deprived Northern Israel city: an ecological study

Vaccine coverage was lower in UO neighborhoods, even in a peripheral city where coverage in non-UO areas is already low. Coverage differences between UO and non-UO populations decreased with time for MMRV1 but not DTP. Our findings suggest timeliness should be considered alongside non-vaccination, and vaccination behavior may be vaccine-specific in the UO population.
