Factors influencing COVID-19 vaccination intentions and the moderating effect of perceived behavioral control among pregnant women: a cross-sectional study applying the revised Theory of Planned Behavior.
So Youn Kim, Hee Sun Kang, Mijong Kim
PMID 40210298WHAT IT FOUND
Pregnant women's intention to get vaccinated was predicted by their own positive attitudes and by pressure from family or friends.
Women who felt vaccination was easy were more responsive to this social pressure. Those who felt it was difficult needed attitude-focused support instead.
Key findings
01Positive attitudes toward the vaccine and subjective norms (pressure from others) significantly predicted intention to vaccinate, explaining 44% of the variance.
02Perceived behavioral control did not directly predict intention but moderated the effect of subjective norms, with social pressure having a stronger effect on women who felt vaccination was easy.

What it does not show
Participants were recruited via convenience sampling from an online community, limiting generalizability. The study measured vaccination intention, not actual vaccination behavior. The cross-sectional design cannot establish causality.
Declared interests
The authors declared no conflict of interest. The study was supported by the Hannam University Research Fund.
The easy way to misread this
Do not assume that telling a hesitant pregnant woman that 'everyone is getting vaccinated' will work. The study shows that social pressure only significantly increases intention if the woman already perceives the vaccination process as easy. For those who find it difficult, this approach may fail.
