Step 1: Designing and Administering Vaccines

March 23, 2014
Our first meeting was a success!

1) List 4 types of vaccines:
-live attenuated (pathogen is alive, but weakened)
-inactivated (pathogen is dead)
-subunit (just a piece of the pathogen + an 'adjuvant' like alum)
-toxoid (the toxin produced by the pathogen, chemically inactivated)


2) Model them with donuts:
-scraped off the frosting (measles, mumps, chickenpox)
-smashed (polio, Hep A, rabies)
-sprinkles only + alum adjuvant (Hep B, pertussis, HPV)
-cream filling 'toxin' (diphtheria, tetanus)

3) We examined the kitchen-shelf version of alum (used for canning vegetables) and went over how it stimulates the immune system and is used in subunit vaccines.

4) Wet lab:  Alexi made her very own REAL vaccine!
-protein from the inside of the flu virus + alum + saline

5) Centrifuge vaccines to demonstrate that protein is fully adsorbed (stuck to) to alum

6) Inject real research subjects: nine 'black 6' mice
-injected intramuscularly, just like how most vaccines are given to humans
