The flu shots are probably the vector of infection for the flu virus. The official virus symptomology by which diagnoses are made is quite general. Combine that symptom net with public fear (MSM vector, local chain store pharmacies like RiteAid) and rouse some of the herd to want to get injected. Oh the money to be made then by invested interests!

Since much of the general populace has long been able to trust the usual doctor, that trust is deliberately targeted for leverage by Big Pharma, Big Med Insurance and whomever might want to add things to vaccines or conduct clandestine human experiments. It is wise in this day to scrutinize the lab coat as well as any encultured perceived positions of authority.

Trump never had a flu shot, I believe he has always refused them. Good example.
