Does anyone know how long the mRNA of a vaccine will linger in a human?
If it lingers only few months, then pretty much all possible related side effects should show up by then.
I think it is too early to reach any conclusion regarding longevity of mRNA in humans because there were no mass inoculations of mRNA until only 3 months ago.
But I have not heard of many deaths from covid-19 of the 55 million people who received the vaccine so far. On the other hand almost all people who have died from covid-19 were never vaccinated.
Median half-life of about 10 hours. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC403777/
Not weeks, nor months. Half-life of 10 hours. If the vaccine has 1,000,000,000 mRNA strands in it, they're all gone within a week.
Don't buy a ticket on the fear train. The first recipients in the Phase 1 clinical trials got their shots in March of 2020. They're doing just fine.
