A new study, published in the PLOS Journal on 10/23, by contributing authors from the Scripps Institute and the University of Pennsylvania, is titled: "A structural explanation for the low effectiveness of the seasonal influenza H3N2 vaccine."
Oops. Low effectiveness? The public has been taught to believe the vaccine is quite effective.
Here is a key quote from the study: "It is common to use chicken eggs for culturing clinical isolates and for large-scale production of vaccines. However, influenza virus often mutates to adapt to being grown in chicken eggs, which can influence antigenicity and hence vaccine effectiveness."
Translation: The virus in the vaccine mutates, in the chicken eggs, and therefore the patient's immune system responds to the wrong version of the flu virus.
Here is another quote: "Our study describes a mechanism [that explains]…the low influenza vaccine effectiveness and reaffirms the urgency for replacing the egg-based production of influenza vaccines."
