Timeline: Vaccines

 Infectious diseases killed hundreds of million people, made empires and civilizations vulnerable, and recently took away our freedom to go out, walk, work, travel, meet friends, and visit relatives during the Covid-19 lockdown. Vaccination freed humans from most of infectious diseases of the past. By starting with a virus grown in a cow, vaccination has been propelled by new technologies such as viral growth in eggs and cell culture, chemical conjugation, recombinant DNA, genomics, and synthetic biology. The revolutionary progress in science and technologies increases the confidence that vaccines will continue to provide solutions for the wellbeing of modern society.
