Believe: Complexity – Thu – 21-03-04



We live in historic times because the Covid-19 vaccines are a breakthroughs in creation of vaccines. It used to be vaccines were made by weaking a virus. But with the Pfizer vaccine, scientist have learned to genetically engineer a vaccine. Listen to this description from Wired.com:

“The active ingredient inside their shot is mRNA—mobile strings of genetic code that contain the blueprints for proteins. Cells use mRNA to get those specs out of hard DNA storage and into their protein-making factories. The mRNA inside Pfizer and BioNTech’s vaccine directs any cells it reaches to run a coronavirus spike-building program. The viral proteins these cells produce can’t infect any other cells, but they are foreign enough to trip the body’s defense systems.”1

This is the description of what happens inside a human cell. Very smart researchers have studied genetics and the human immune system — a highly complex system. Now scientists can use that knowledge to create a vaccine in record time.

The cell’s function is an example of irreducible complexity,2 meaning something so complex that no part can be removed without the whole ceasing to function. Something this complex does not evolve bit by bit over time, the entire system is needed to function. If it took years of research to understand DNA and advance to engineering a vaccine, don’t you think it required God’s intelligence to design the cell  and human immune system in the first place?
