TL;DR: The RTS detects epidemic onsets at an earlier stage, facilitating more detailed epidemiological analysis, compared with that of the NESID, and identified a strong correlation, confirming the reliability of the RTS.
Journal ArticleDOI
Persistence of Antibodies against Diphtheria, Tetanus, Pertussis, and Poliovirus Types I, II, and III Following Immunization with DTaP Combined with Inactivated Wild-Type Polio Vaccine (DTaP-wIPV).
TL;DR: The need for an additional preschool booster immunization using DTaP-wIPV is suggested, as a significant increase in anti-PT antibodies was observed in 6 subjects, suggesting subclinical infection.
Journal ArticleDOI
Bias of vaccination coverage in a household questionnaire survey in Japan.
TL;DR: The results suggested that vaccination coverage from a household questionnaire survey in Japan might not be extremely biased by either non-responses or incorrect answers.
Journal ArticleDOI

TL;DR: The VIS improved parent comprehension of infant immunization in Japan, and future studies should examine if the effects of such an intervention persist and affect vaccine uptake throughout childhood.
Journal ArticleDOI

TL;DR: Enteropathogenic Escherichia coli (EPEC) strains produce a bundle‐forming pilus (BFP) that mediates localized adherence to intestinal epithelial cells and functional deficiency due to frameshift mutation and subsequent nonsense mutation in perA reduced BFP expression in typical EPEC strains isolated in Japan.
