In life and in science, changes have consequences. With hindsight, the bad ones are easy to see, some may argue. But when we examine the natural consequences of changes in the arena of Covid vaccine science, one might be forgiven for asking: surely someone must have cautioned against doing that? Of course it behoves us to state here, before we examine those consequences: that’s why new drug/vaccine products are supposed to be thoroughly tested before they are given to large populations.

In 2005, Drs. Weissman and Kariko discovered a way to protect foreign mRNA from the body’s immune system. That scientific milestone would be key to the advancement of the mRNA vaccines in 2020.

Recently, the University of Pennsylvania Tweeted a picture of the Drs. Weissman and Kariko receiving their Covid vaccination, and reminding us of that milestone. One tweet commenting that they should receive the Nobel prize for their discovery.
