Experts from Yale University have discovered an alarming syndrome linked to the mRNA Covid vaccines.
Persistent spike proteins in the body are thought to cause some of long Covid's symptoms, by keeping the body in a constant state of inflammation.
This was true in patients who received their vaccines between 36 and 709 days prior.
Dr Iwasaki said: 'That was surprising, to find spike protein in circulation at such a late time point.
'We don’t know if the level of spike protein is causing the chronic symptoms, because there were other participants with PVS who didn’t have any measurable spike protein.
We performed ...vaccine mRNA-specific RNAScope probes in the core needle biopsies of the ipsilateral axillary LNs (lymphnodes) that were collected 7–60 days after the second dose of mRNA-1273 or BNT162b2 vaccination and detected vaccine mRNA collected in the GCs (germinal centers) of LNs on days 7, 16, and 37 postvaccination, with lower but still appreciable specific signal at day 60
immunohistochemical staining for spike antigen in mRNA-vaccinated patient LNs (lymphnodes) varied between individuals but showed abundant spike protein in GCs (germinal centers) 16 days post-second dose, with spike antigen still present as late as 60 days post-second dose.
A new study by Australian researchers revealed that one third of patients who suffered from myocarditis after getting a COVID-19 vaccine still had heart scarring more than a year later. This is according to cardiac imaging that showed persistent late gadolinium enhancement (LGE), which is typically an indicator of heart scarring.
In the study, the median time between the day the person received the vaccine and when they underwent follow-up imaging was 548 days; the longest interval among those studied was 603 days.
The researchers wrote: “We found that the incidence of persistent myocardial fibrosis is high, seen in almost a third of patients at >12 months post diagnosis, which could have implications for the management and prognosis of this predominantly young cohort.”
Mass spectrometry examination of biological samples was used to detect the presence of specific fragments of recombinant Spike protein in subjects who received mRNA-based vaccine.
The specific PP-Spike fragment was found in 50% of the biological samples analyzed, and its presence was independent of the SARS-CoV-2 IgG antibody titer. The minimum and maximum timeat which PP-Spike was detected after vaccination was 69 and 187 days, respectively.
