Researchers in Ulm have discovered protein contamination in the Astrazeneca vaccine.
This could be the reason for some of the side effects of the vaccine.
Munich - The vaccine from Astrazeneca * does not have the best reputation *.
Although even Chancellor Angela Merkel was vaccinated against Corona * with Astrazeneca, many citizens have reservations about the preparation, especially in connection with cerebral vein thrombosis.
Now a research group from Ulm University has made amazing discoveries in Astrazeneca vaccination doses, as

Focus Online
.
Astazeneca: Unwanted proteins in the vaccine - effect influenced?
Accordingly, the batches examined contained components that should not be part of the vaccine at all: larger proportions of human and viral proteins, which apparently come from the seed cultures for the vector viruses.
According to the researchers, it is conceivable that the contamination could influence the vaccine effect and promote side effects - for example sinus vein thrombosis.
Instead of the expected 12.5 micrograms of protein, the samples contained up to 32 micrograms.
Further analyzes followed, which revealed that the vaccine contained more than 1,000 proteins and protein fragments, most of which were not intended.
One third of these were of viral origin and two thirds of human origin.
Impact for vaccinates from Astrazeneca: "Should not have any negative effects"
What does that mean for the vaccinated?
"The majority of the proteins found should not have any negative effects on vaccinated people," explains research director Stefan Kochanek to the portal.
But he also warns: “Extracellular heat shock proteins are known to modulate innate and acquired immune responses and to intensify existing inflammatory reactions.
They have also been linked to autoimmune reactions. "
Effectiveness of vaccination reduced by excess proteins?
Researchers are calling for improvements
The researchers went on to explain that the excess viral proteins could make the vaccine less effective.
In addition, the proteins are said to be responsible for the strong side effects *: "We consider it likely that the protein contamination documented here is involved in the strong clinical reactions with flu-like symptoms that are often observed one or two days after the vaccination."
The researchers call on the manufacturers to clarify the contamination and improve the vaccine.
“This could not only increase safety, but also increase the effectiveness of the vaccine.” The removal of all protein residues is normally an important quality standard.
