Brief Summary

The goal of this InTroDuce-Programme interventional trial aims to test whether a web-based educational program can improve pregnant women's knowledge about Influenza and Tdap vaccinations and increase their intention to get vaccinated in the future. The main questions it aims to answer are: Does the InTroDuce-Programme increase knowledge and future intention of pregnant mothers to get vaccinated against Influenza and Tdap? How does demographic factors, attitudes and barriers affect vaccination decisions among pregnant mothers? Researchers will compare InTroDuce-Programme to standard care (routine antenatal care) to see if InTroDuce-Programme works to improve knowledge and future intention of pregnant mothers to be vaccinated against Influenza and Tdap. Participants will: Receive the web-based educational module (InTroDuce-Programme), which covers the importance, safety, and effectiveness of vaccinations, as well as addressing common concerns. Be followed up one month after the intervention. Answer questionnaires before and after the intervention to measure changes in vaccination knowledge and future intention to get vaccinated
