In 2021, the MumBubVax.org.au website was expanded to include an interactive Flu Decision Aid to support pregnant women to make informed decisions about flu vaccination during pregnancy. 

​

The Decision Aid contains highly credible information about influenza and its impacts on pregnant women and their babies, and on the risks and benefits of the available vaccines. It also contains a digital tool that allows women to reflect on their own values and concerns, and to prioritise these for discussion with healthcare providers.
