Enhanced flu protection: Four beats three

13 marzo 2015

New research findings parallel earlier results: Adding a strain of influenza B could improve effectiveness of an influenza vaccine. Findings from this study of flu vaccines delivered by a small needle intradermally parallel earlier results that found adding a strain of influenza B could improve the effectiveness of a flu vaccine nasal spray and a traditional intramuscular vaccine that is injected as a shot in the arm muscle. All studies showed the addition of the B strain improved the antibody response to that strain and didn’t weaken the body’s immune response to other flu strains in the vaccine.
