The covid vaccine spike protein sequence circulates in your blood for at least 28 days.

In this study done in Denmark, a clinic followed their Hepatitis C patients  after receiving the Pfizer or the Moderna vaccine.  In 10 of 108 patient samples, full-length or traces of SARS-CoV-2 spike mRNA vaccine sequences were found in blood up to 28 days after COVID-19 vaccination.

What makes this study important and fascinating is this: according to the powers that be at the “vaccine companies”, The half-life of mRNA translation is estimated to be short, from hours to a day and translation is described to span up to 10 days [4-6 days on average]. The Infectious Diseases Society of America (IDSA) informs that the vaccine mRNA is degraded quickly by normal intracellular processes and states that there is no evidence for long-term detection of mRNA vaccines in vaccinated individuals by RNA-sequence.

That is not true.  This study shows that the MRNA does not break down in hours to a day, nor does the translation of the MRNA end as it should in the 4-10 day window.

This study has implications for all future MRNA vaccines.  If the MRNA is not degrading in hours to a day as advertised, this study concludes that changes need to be made to how we make MRNA vaccines.

“We expect that vaccine mRNA detected in plasma is contained within LNPs and that the LNPs in plasma have been slowly released from the injection site either directly to the blood or through the lymph system. Without the LNPs protecting the mRNA, the mRNA would rapidly degrade. This allows prolonged spike protein production giving an advantage for a continuous immune response in some persons. Current studies on half-life of mRNA vaccines could have underestimated the half-life of the LNPs, primarily using results from half-life of studies of mRNA in the cytosol of human cells. A future prospective study to establish the half-life of mRNA vaccines in vaccine recipients could be performed using mRNA vaccine-specific PCRs. These findings are interesting and should lead to further research into the design of LNPs and the half-life of LNPs and mRNA vaccines.

Sadly, they also add the “we are not antivax” disclaimer at the end, but I suspect that was to get the info out there and not get the publish of their findings banned.
