What makes Chinese vaccines to covid19 toxic

SPF is the abbreviation of  Specific Pathogen Free.

  In 1950, Sunrise Farm established the first commercial SPF chicken flock.

In 1959, the Regional Poultry Research Institute of the United States Department of Agriculture established SPF chicken flocks for laboratory research based on research needs.

In 2016, SPF breeding eggs were introduced (ie stolen) from the United States by Chinese Communist party (CCP) and the first SPF chicken flock was successfully cultivated in Shandong, which filled the domestic gap.

In addition to being used to make vaccines for animals such as chickens, SPF eggs have a more important purpose --- to make vaccines for humans.

How to use SPF eggs for vaccine research? Take an example of leukemia vaccines.

If you want to produce a leukemia vaccine, you can inject the leukemia seed virus into the SPF egg, which is to put 300 eggs on three hundred pillows of the same height. After the seed virus is diluted to a certain level, the eggs are injected into the embryo. Big head and small head. There is a gap on the big head. It is called the air chamber. It is used for embryo breathing. When the needle is inserted, it needs to pass through the membrane of the air chamber to put the poison down and enter the allantoic fluid (similar to human amniotic fluid), then the pinholes on the eggshell were sealed, and the hatching continued. After 72 hours of incubation, the seed poisons planted began to reflect on the chicken embryos, and antibodies were produced (research results show that at 72 hours, the amniotic fluid is most, The antibody is the highest.) The allantoic fluid is what is needed to produce the vaccine. After it is extracted, it is filtered. After the filtration, the antibody-containing fluid is left, and the live vaccine can be made. If it is an ordinary chicken embryo, it will have viruses such as encephalitis, influenza, and Newcastle disease, which cannot be filtered out, and SPF eggs are planted with any virus, and there will be no other virus bacteria.

After the vaccine is produced, how to ensure the titer? Researchers need to inject the SPF experimental chickens for experiments to determine the effect of the vaccine.

But what the CCP stole was the SPF technology used for animal vaccines which disallowed 35 viruses within the eggs while SPF eggs for human vaccine disallowed 40 viruses.
