Purpose: The adult tetanus, reduced diphtheria, and acellular pertussis (Tdap) vaccinehas been introduced in order to provide individual protection and reduce the risk of transmitting pertussis to infants. We assessed the knowledge and acceptabilityof the Tdap vaccine around pregnancy. Materials and Methods: This study was a cross-sectional survey of women of childbearing age (20‒45 years) who visited obstetrics and gynecologic units of primary, secondary, or tertiary hospitals. They were asked to fill in a questionnaire assessing their knowledge, attitudes, and acceptabilityof Tdap. Results: The questionnaire was completed by 308 women; 293 (95.1%) had not received information from doctors about Tdap, and 250 (81.2%) did not know about the need for vaccination. A significantly important factor related to subjects’ intention to be vaccinated, identified by stepwise multiple logistic regression,was the knowledge (OR 13.5, CI 3.92‒46.33) that adult Tdap is effective in preventing pertussis for infants aged 0‒6 months. Additionally, 276 (89.6%) consideredthe recommendation of obstetric doctors as the most influencing factor about Tdap vaccination. Conclusion: In Korea, most women of childbearing age seem to be neither recommended nor adequately informed about the vaccination, although our population was not a nationwide representative sample. Information given by healthcare workers may be critical for improving awareness and preventingpertussis
