Hello, my name is Anita Milicic.
I lead the Vaccine Formulation Group at The Jenner Institute, University of Oxford.
This lecture will cover the concept of
vaccination and different aspects of vaccine development.
Vaccination is widely considered the most
transformative human health intervention in history.
Its role in global health security as well as
economic prosperity has come into sharp focus during the COVID-19 pandemic.
In addition to saving lives,
vaccination contributes to better health, longevity,
and high productivity and will be a vital tool
in the battle against antimicrobial resistance.

worldwide immunization efforts finally lead to smallpox elimination.
In the recent years,
we have witnessed the emergence and re-emergence of pathogens with
pandemic potential bringing new challenges for vaccine developers.
The link below is an excellent general source of information on all licensed vaccines.
The principle of vaccination or variolation as it was
termed originally dates back to at least 15th century China.
There are written descriptions of widespread practices that involved grinding up dried

the skin in the attempt to prevent often deadly natural infection.
The practice which was essentially passing
the infectious material from one person to the other,
spread through the 17th and 18th centuries across the Middle East and Africa.
The first scientific proof that vaccination can
