6M Vaccines & flu shot

So my daughter turned 6 months old yesterday, she had her 6 month vaccine & i allowed her doctor to give her the flu shot..

What are the side effects your children get their vaccines/flu shots?

My daughter is usually just more clingy, fussy, & more sleepy.

But today she’s been throwing up (not much), & has been running a low grade fever. I have given her some Tylenol.

But wasn’t sure if that was normal? She’s also teething, so I’m not sure if the throwing up part is caused by the extra saliva..
