Since the beginning of human history, we have been at war with an
invisible enemy. Microbes. These tiny organisms can spread terrible
diseases. Ramses V, Pharaoh of Egypt may have died of smallpox; in 1918
a new illness called the Spanish Flu killed 50 million people in 18
months; and in the fourteenth century the black death killed more than a
quarter of the population. In more recent times Covid 19 has changed the
way we live. But there's good news too! Human scientists have learned to
fight back. In the 18th century edward Jenner developed the first
vaccine, and since the 1930s penicillin has saved millions of lives. And
many microbes are helpful. They help our digestion, give us powerful
medicines and even food. This is the Microbe Wars. It's good, it's bad
sometimes it's ugly, but it's a scientific journey filled with
innovation and hope.
