Many of you are looking for the flu vaccine, but you can't find it at pharmacies.
However, you might be able to get your hands on Tamiflu, which treats you after you start to feel sick.
Doctors say Tamiflu helps stop the virus from replicating in your body -- sometimes cutting the amount of time you are sick by up to half.
Pharmacists say it only works if you take a dose within 48 hours of feeling symptoms.
But remember, try to avoid getting sick in the first placed by washing your hands and avoid touching your face.
Also, stay home if you're feeling sick. New research finds just breathing can spread the flu.
You can also reduce your risk by getting the flu vaccine, if you can find it at your pharmacy.
