FLU SHOT?

so my doctor is highly suggesting me to get the flu vaccine. I’m not against it i just don’t want to get it. I feel as if there is no need because you can still catch the flu wether your vaccinated or not. They say it just puts you at lower risk for the symptoms or whatever but what about all the chemicals that’s in the vaccine? I’m debating wether to get my daughter the flu shot. We get all of our other shots just haven’t gotten the flu shot yet but with all these cases of the flu going around I’m unsure about it like the side effects and long term etc. any moms who have kids or have already gotten vaccinated or chose not too can state your opinion below. I just want to get a better insight what do you guys think?
