Can I call you back? <a href=" http://mirrorofrace.org/can-you-buy-propecia-online-no-prescription.pdf#curvature ">where to buy propecia cheap</a> That’s a great question, and it’s one we hear every year. And I think there’s a couple ways to answer that question. I’ll start by saying, the flu vaccine cannot give you the flu. The vaccine includes either a killed version of the virus, or a component that’s been altered in a way such that it’s not infectious. Some of the new vaccines have just a small component of the virus, one single protein, and not the virus at all, so they cannot be infectious. There’s one vaccine formulation that’s brand new this year, that’s a purified protein vaccine, and it contains a small part of the influenza virus, just a protein essentially, and that helps provide immunity from influenza. So, it’s non-infectious. It cannot give you influenza, and in fact, none of the vaccines can give you influenza.
