How did Vaccines start?
Edward Jenner is considered the founder of vaccinology in the West in 1796, after he inoculated a 13 year-old-boy with vaccinia virus (cowpox), and demonstrated immunity to smallpox. In 1798, the first smallpox vaccine was developed.
How do they weaken a virus for vaccines?
There are four ways that viruses and bacteria are weakened to make vaccines: Change the virus blueprint (or genes) so that the virus replicates poorly. This is how the measles, mumps, rubella, and varicella vaccines are made.

How old are vaccines?
We begin our history of vaccines and immunization with the story of Edward Jenner, a country doctor living in Berkeley (Gloucestershire), England, who in 1796 performed the world’s first vaccination. Taking pus from a cowpox lesion on a milkmaid’s hand, Jenner inoculated an eight-year-old boy, James Phipps.

The smallpox vaccine, introduced by Edward Jenner in 1796, was the first successful vaccine to be developed. He observed that milkmaids who previously had caught cowpox did not catch smallpox and showed that inoculated vaccinia protected against inoculated variola virus.
How are vaccines made CDC?
The fluid containing virus is harvested from the eggs. For inactivated influenza vaccines (i.e., flu shots), the vaccine viruses are then inactivated (killed), and the virus antigen is purified. The manufacturing process continues with quality testing, filling and distribution.
