Flu shot??

Okay guys. I'm not here to get hate or anything. I have a honest question. Should I have my 6 month old get a flu shot?? My husband is against vaccines so he says no. But he's fine if I do whatever. And honestly don't really know what to do. His mom is against them also. I'm not against and I wouldn't say I'm for because I don't know much about them. The Dr highly suggests it. The pharmacist at my work says I should wait until next year because she is so young. She doesn't go to daycare she is watched by her grandma. Just wanted some advice on what to do.
