Can the nasal-spray flu vaccine LAIV (FluMist®) be used together with influenza antiviral medications?
If a person is taking an influenza antiviral drug (including Symmetrel (amantadine) for Parkinson’s disease), then the nasal-spray flu vaccine should not be given until 48 hours after the last dose of the influenza antiviral medication was given. If a person has received the nasal-spray flu vaccine, an influenza antiviral medication should not be given until 2 weeks after the nasal-spray flu vaccine was administered.
