NOt to mention how chronically incompetent the flu shot is a actually protecting people from the current year's seasonal influenza.
It is a loosing battle even if it is 100% protective there will still likely be a strain of influenza (not in the shot) that takes off because people's immune systems are that compromised.
There are way too many strains of influenza and it is changing too quickly to ever have a effective flu shot. Let alone all the side effects that can come with it like the explosion of autoimmunity that American healthcare systems are trying to deal with.
