"The answer to AIDS lies in biologics"
What is "biologics"?
Sorry, for the criptic language.
In the pharm R & D areas, there is chemistry and there is biologics.
Biologics is a very different kettle of fish, excuse the pun.
Biologics involves using living of formerly living products to develop a result. It is not like making a cake; if you use x amount of baking soda or salt in a recipe in the same amount each time you get a measured result. Using living or formerly living products in development injects the idiocyncracies of each individual "creature" itself into the process of development and manufacture.
This is why you hear about Pharm companies having to toss entire batches of vaccine. It is painfully hard to develop and just as difficult to manufacture.
By the way, researchers have kids, too and believe me, those kids are vaccinated.
Soon things will be made easier by the use of gene replication techniques in development and manufacture.
Antibiotics were developed out of the field of biologics.
Folks forget that more men died in WWI from the flu than did from war injuries. Over a million (a very high percentage of our population at the time) died of it around 1918 or so.
There was no flu vaccine.
