This is not my usual post, especially for my card blog. But a cousin posted a link to one of the best explanations I’ve seen on how we developed vaccines 40-50 years ago and how we are doing it today.
It is “part of a new age of vaccine technology, in which we can send our own bodies the instructions on how to protect themselves” that has greatly shortened vaccine development and production time without sacrificing the efficacy. It’s amazing to think about what we know (and are learning) about the human body and how it functions.
I hope this helps you understand the approach to the new COVID vaccines and future vaccines we may need for other diseases and virus.
Thanks for stopping by today. Hugs to all of you, and happy stamping!
