Flu shot for 3YO

Hello moms,

Just wondering where you get your flu shots for your 3YO ??

Pharmacy?? Or doctors office??

My 3YO doesn’t have any appointment until she’s 4 so I’m wondering if I can go to a pharmacy to get flu shot and it will be faster????

But what do they usually ask for there?

Is it safe and they will give the right dose for their age? Do they check their vaccine records?

Also have your children gotten sick after getting the shot?

Thanks!
