Flu vaccine for infant

So I vaccinate my baby- he’s 5 months old so we’re approaching him being able to get a flu shot at his 6 month appt. I myself have only had the flu shot once in my life and that’s when I was pregnant. I worked in an OBGYN office and it was mandatory or wear a mask, so I got it. Otherwise I’ve never seen a need truly for it. Anyways what are your thoughts on the flu shot for babies? This is mainly for vaccinating parents. Not trying to start some big feud.
