Biodistribution and Spike Protein Safety of mRNA Vaccines: An Update
It’s easy to misinterpret science, and it takes more effort to understand the true narrative.
In the past few months, there has been a push for the idea that the spike proteins related to mRNA vaccines are toxic to our bodies. The vaccine can cause spike protein deposition in the ovaries, for example, but is this really true? I wish there were a yes or no answer to this question, but the science behind it isn't so straightforward. Rest assured, however, that the mRNA vaccines aren't toxic to the ovaries or any other tissues.
This article will explain why, as objectively as possible, and also serve as an update to a related article about spike protein safety I wrote back in December 2020 and another one about mRNA vaccine biodistribution I wrote four months ago.
How Covid-19 vaccines work in brief
Nearly all the vaccines against Covid-19 use the SARS-CoV-2’s spike protein to induce immunity in some way or another. (SARS-CoV-2 is the coronavirus that causes Covid-19.)
The mRNA vaccine, for example, uses lipid nanoparticles (LNPs) to deliver mRNA into cells. This mRNA instructs the cell to make the spike proteins of SARS-CoV-2 that provoke immune…
