Part 2: “Unexpected things happen when you start fiddling with the innards of living cells.”

 What constitutes “fiddling with cells”?

Yesterday, I posted that:

  • The above warning from the book Code Breaker resonated with me
  • My most trusted med-science sources told me that the warning was applicable to covid vaccines
  • Specifically, all of the current emergency- approved covid vaccines “fiddle with cells”

All of which begs the question: What constitutes “fiddling” and what might be the ”unexpected results” ?

Let’s drill down on that question…


All of the current emergency-approved covid vaccines are fundamentally different than the traditional vaccines that have been used in the past.

The “classical” battle-tested vaccines typically inject a person with a minute amount of the suspect pathogen (or a very near variation of it) that activates a person’s immune system … putting it in a high state of readiness to fend off the disease if and when they were exposed to it.

The traditional vaccines didn’t “fiddle with the innards of cells” … or, in any way, mingle with a person’s cellular DNA.

No harm, no foul.


Not so with the  current crop of emergency-approved vaccines.

Note: As of now, no covid vaccines have been fully approved by the FDA. Pfizer, Moderna and J&J are all currently being administered under an emergency use authorization.

Simply stated, they inject RNA or DNA that finds its way to cells and induces production of preventative antigens that fight off the coronavirus.

Pfizer & Modera are mRNA vaccines (the “m” stands for “messenger).

The vaccine particles “bmp into cells” and fuse to them, releasing the mRNA into the cells.

The cells “read” the mRNA genetic sequence and build spike proteins that combat the coronavirus.

Two key points: (1) Pfizer & Moderna contain RNA, not DNA, and (2) the RNA penetrates cells, but not the cells’ nuclei (where DNA is stored).

Though mRNA hasn’t been used as a vaccine modality in the past, it has been researched for decades and generally presumed to be safe — both short- and long-run since it “fiddles” with cells, but does not penetrate cells’ DNA-storing nuclei. And, the fragile mRNA from the vaccine is “eventually destroyed by the cell, leaving no permanent trace.”

For more detail (and some clever graphics) see the NY Times summary of How the Moderna vaccine works.


OK, that covers the the two emergency-approved mRNA vaccines (Pfizer & Moderna).

Based on clinical trials and vaccinations to date, both have proven to be very effective and reasonably safe … especially for older adults.

Note:The general presumption of short-tern safety has recently been called into question because of the incidence of myocarditis (inflammation around the heart) among teens and young adults, especially young men,  See: The CDC’s All-or-Nothing Approach to Teen COVID Vaccination Is All Wrong

That’s why I readily took the Moderna shots as soon as I could (and would have taken Pfizer if it had been offered).

But, what about the J&J vaccine?

Well that’s where, in my opinion, things get a bit stickier.
