According to Dr. Richard Ennos, a retired Professor of Evolutionary Biology at Edinburgh University, his analysis of the U.K.'s COVID-19 ‘Yellow Card' vaccine data for Pfizer and Moderna vaccines suggests “unequivocal safety signals” for adverse reactions that impact blood, heart, and female reproduction. He believes that the mRNA vaccines should be withdrawn immediately based on his findings.
In the UK, there are three COVID-19 vaccines – AstraZeneca (AZ), Pfizer (PF), and Moderna (MO) – being used in a nationwide vaccination campaign to prevent harm from the SARS-CoV-2 virus.
All three vaccines provide the genetic code for the spike protein of the virus, which is linked to the development of COVID-19, so that the vaccine recipient's body can produce it. The AZ vaccine uses DNA for the spike protein genetic code and introduces it into the recipient's cells through a modified chimpanzee adenovirus vector. The genetic code used in PF and MO vaccines is modified RNA carried by lipid nanoparticles. The vaccines cannot control which tissues they reach, and how long those tissues will produce spike proteins.
The three available vaccines use new technology that has not been tested in humans before.
