Knowledge, perception and maternal immunisation practices of obstetricians in Singapore for the Tdap and influenza vaccines

Obstetricians' knowledge and perception of evidence-based recommendations may influence the uptake of antenatal tetanus, diphtheria and pertussis (Tdap) and influenza vaccination. Our survey aimed to assess the knowledge, perception and practices of local obstetricians regarding delivery of antenatal Tdap and influenza vaccines, and perceived barriers to maternal immunisation. There was generally adequate knowledge that Tdap and influenza vaccination in pregnancy was safe, effective and beneficial. However, knowledge regarding recommendations in local guidelines was poorer for Tdap compared to influenza vaccination. Lack of time for patient education was the top perceived barrier for both Tdap and influenza vaccination. A significant proportion of obstetricians cited uncertainty regarding recommendations as a reason for not routinely offering maternal immunisation. These findings demonstrate an urgent need to raise awareness of evidence-based recommendations regarding maternal immunisation, and to promote Tdap and influenza vaccination during antenatal visits so as to improve maternal immunisation rates in Singapore.
