Medical mavericks - the history of self-experimentation. Part 2, Discovering vaccines.

The second in a four-part series, presented by Michael Mosley, looking at the history of medical self-experimentation. This part features people in medical history who have sought out vaccines. We begin by looking at the latest research into how hook worm infection can suppress the over-active immune systems of people who suffer from allergies. Then Mosley traces the history of self-experimentation in the quest for vaccines including Pasteur's discovery of a rabies vaccine, Wright's work with a vaccine for typhoid and the many attempts to find a polio vaccine. The programme is filled with historical medical information, archive footage, expert accounts and is highly informative for anybody interested in the history of medical self-experimentation or vaccination.
