Which one: take your chances and risk getting the flu or get the flu shot? Getting sick with the flu is like getting hit by a truck, and you risk hospitalization or death, even if you are a healthy person. Getting vaccinated as insurance for protection from influenza is a no-brainer.
Unless you are in the rare exception group, everyone older than 6 months is recommended for flu vaccination.

No – you can’t get the flu from the vaccine: the viruses that make up the flu shot are inactivated (killed), therefore they cannot cause infection.

The worst thing you get from the flu shot is a slightly sore arm. There is a 0.00001 % chance of experiencing a life threatening reaction to the vaccine. I did the math for you.
Get your flu shot.
