I had the flu shot in the second trimester for both my pregnancies, and both my babies are fine. The fluvax would take about 2 weeks to get full cover, so if you catch the flu from your DD, the fluvax will not protect you anyway in the next fortnight. If you do not catch the flu from your DD and get the fluvax, it will offer your baby protection while you are BF.

I get the fluvax every year and have never had a case of the flu. This does not mean you will not catch a cold or get a chest infection as there are thousands of viruses that can cause these type of illness. Flu is just the more severe virus.
