The Third Pandemic

The third pandemic began in 1855 in China and spread to India. Over the course of that one year, more than 12 million people died in those two countries alone. The root of transmission via infected fleas was identified during this pandemic. There is a functional plague vaccine, but it still has its problems with longevity on the logistical side. It takes multiple courses to immunize. Antibiotics are still effective against plague. For now. Thank goodness for now.
