The seasonal flu vaccine this year protects you against three influenza viruses that are thought to be most common.   Around two weeks after you are vaccinated antibodies develop that protect against the influenza virus infection. Keep in mind that a Flu vaccine will not protect you against flu-like illnesses that are caused by non-influenza viruses. Vaccinations begin in September and are available until May.  Get a vaccination today from your Loveland Physician or participating pharmacy.
