I have gotten them at the doctor's suggestion
since I turned 58 (7 yrs).
My wife is an RN & works in a hospital geriatric center.
The hospital wants all employees to get the shots.
I don't want her bringing home some nasty virus, either.
I want to be sure I won't give it to my quadriplegic son (immune system compromised-baclofen & other drugs), or my small & infant grandkids.
I've never had a bad reaction other than the injection site being sore for a day or so.
