Breakthroughs – The term breakthrough has an established history in vaccinology—counting up these events is necessary to know how well inoculations are working in and out of trials.


Evidence-based medicine – Medical practice or care that emphasizes the practical application of the findings of the best available current research.  


Fully vaccinated – To reduce the risk of getting infected or seriously sick  with a disease, and decrese the chances that the virus will be passed on to others.  Often vaccine effective rates are given as a percentage such as 95% effective.  This mean you have a 5% chance of getting the disease.  This term is often misunderstood.   It takes your body several weeks to become disease resistant after vaccination.

Vaccine-acquired immunity – Immunity via a vaccine such as Polio vaccine.  this takes place in the days and weeks following a vaccination where the bodies immune system developed antigens to inactivate a pathogen.

Vaccinology – A field recently that has come into existence.  An expertise related to the creation and deployment of vaccines. The field ‘borrows’ from epidemiology, immunology, infectious disease, pediatrics, preventive medicine, public health and virology.
