Vaccinations: Not Just Kid Stuff
Vaccines 101 How Are Vaccines Made?

Vaccines contain diseases that have been safely weakened. This does not cause the disease, but actually helps your body learn to fight it. There are several different types, and each is developed to fight differently against the disease it targets.

Vaccines can be grouped in the following categories:10

Type of vaccineHow it’s madeWhat it means for youExample
Live (attenuated) vaccinesThese contain a safely weakened version of the living bacteria or virus so it can’t cause disease. Because a live vaccine is the closest thing to a natural infection, your immune system reacts strongly. This means you can often get lifelong protection with only one or two doses. Measles, Mumps Rubella (MMR) and Influenza live vaccine (intranasal)
Inactivated vaccinesThe bacteria or virus is killed with chemical heat or radiation. Your immune systems reacts less strongly to these (compared to live vaccines), so you’d likely need additional doses or booster shots. Influenza inactivated vaccine (injectable)
Polysaccharide vaccinesDeveloped to recognize the sugar coating that surrounds many bacteria, these vaccines come in two forms; Plain or Conjugated Plain (or non-conjugated) vaccines provide protection for a limited time only.


Conjugated vaccines are more likely to provide a steady level of protection. They teach your body to remember the infection so it can more readily fight against it in the future.
Plain (non-conjugated):
Pneumococcal vaccines Pnemo 23® and Pneumovax 23®

Conjugated:
The new pneumococcal vaccine Prevnar 13®
