Pharmaceutical companies fund med schools in the USA. My MD went to med school in Nigeria and did not push vax on me. Quite the opposite. Best doctor I ever had.
And advertise heavily in medical journals, and hold expensive, lavish "conferences" for doctors in resort locations. A friend of mine's doctor husband went to a pharm-sponsored "conferences" for two nights in Las Vegas and he called home and told her they were showing porn. Other friends have reported "conferences" in ski resorts, in Hawaii, on cruise ships; and lots of "holiday gifts" and assorted trinkets are given by visiting drug reps to prescribing doctors with the brand names of drugs on them.
