Flu shot?


I’ve never had a flu shot and it’s never been an issue for me. Last year my husband, and my baby, and I all got the flu. I honestly wouldn’t have even known that’s what we had except that my daughter (under a year old) had a wellness checkup that day and they tested her for the flu. She barely showed any symptoms and was completely fine. But no my husband is worried and wants her to get a flu a shot this year. Does anyone know the pros/cons of this?
