Pilot Study of Evaluating Attitudes toward Childhood Immunization among Healthcare Workers in Japan

Providing appropriate immunization information during the perinatal period is important for improving immunization rates among infants and children; however, the distribution of immunization information by healthcare workers (HCWs) is not standardized in Japan. We investigated HCWs' attitudes toward childhood immunization and factors related to vaccine hesitancy. We conducted a cross-sectional descriptive survey of HCWs involved in childhood immunization in Niigata City, Japan, from November 2017 to January 2018. We assessed contextual, individual and group, and vaccine/vaccination-specific influences. Of 290 HCWs, 139 (47.9%) returned completed questionnaires. Most HCWs (87/139, 64.9%) reported providing immunization information verbally to parents; 51/87 (58.6%) spent fewer than five minutes doing so. Pediatricians provided vaccines based on the parents' best interest, whereas public health nurses and midwives emphasized government policy. Nurses had greater hesitancy related to personal perceptions and social/peer factors than pediatricians (p < 0.001). Nurses were significantly more likely than pediatricians to suggest that children receive more shots than necessary (p < 0.01). Nurses tended to have more negative attitudes toward vaccination and little awareness of immunization promotion compared to pediatricians. Thus, all HCWs involved in childhood immunization should receive sufficient information to provide timely and appropriate immunization to infants and children.

Automated summary

The distribution of immunization information by healthcare workers (HCWs) is not standardized in Japan, and vaccine hesitancy is higher among nurses compared to pediatricians. Nurses have more negative attitudes towards vaccination and lesser awareness of immunization promotion.
