I agree with you Maruf. In France a titanus ampoule costs 3.6 USD. Only production and retail costs. No hidden costs, research and capital costs were amortized long ago (some other vaccines cost more than 100 USD). The shot by a nurse is 4.1 USD. No hidden costs : it is in her consultation room, she foots any renting, heating ... bills of her office. On the contrary she returns a part of these 4.1 USD in her annual revenue taxes. I went once to a physician to have a titanus shot. I had to insist to pay him ; it was contrary to his etiquette to be paid for a shot; I explained him that one week before it took him 45 min to try to cure me for 29 USD (28 USD paid by my insurance anyway).
