The COVID-19 vaccine may in fact be the most fast-tracked vaccine ever created in all history. However, this rush to be first to the market necessitated the elimination of required safety testing steps, such as animal testing.
Pfizer, in collaboration with BioNTech, began human trials in the U.S. of a COVID-19 vaccine on May 11, 2020. If it seems to be successful, the vaccine could be released as early as September 2020 with an FDA-approved Emergency Use Authorization or (EUA).
Like Moderna and several other competitors, the Pfizer/BioNTech vaccine is using messenger RNA or (mRNA) rather than live or attenuated, inactivated viruses grown in animal cells.
Previous attempts to create coronavirus vaccines have failed, due to coronaviruses triggering production of two different types of antibodies, one that fights disease, and one that triggers “paradoxical immune enhancement” that often results in very serious disease and/or death.
Vaccines that caused paradoxical immune enhancement initially looked very promising, as they produced very robust antibody responses. Yet when exposed to the wild virus, ferrets and children became severely ill and many died.
Which does make us ask the question…
Is something rushed out into the market like this, really safe for me or my family?
