COVID-19 Vaccine Trials

Since mid-2020, COVID-19 vaccine trials have taken place around the world for numerous vaccines.

Moderna Vaccine Trials

Pfizer Vaccine Trials

Major Problems With Pfizer COVID-19 Vaccine Trials

Nonrandomization of Primary Comorbidity
Lack of Blinding

Researcher David Wiseman, PhD walks through how Pfizer trials were unblinded, and details the problems associated. https://podcasts.apple.com/us/podcast/ep-989-how-pfizer-completely-fudged-its-safety-and/id1065050908?i=1000541261581

Ventavia Whistleblower

Pfizer employed third party companies to conduct their vaccine trials, as has become common in the pharmaceutical industry. A trial observer working for Ventavia, Brook Jackson, took note of a number of serious problems affecting the conduct of the trial. She emailed her observations to the Food and Drug Administration at which point she was promptly fired. Her story was not told publicly until over a year later in the British Medical Journal.10)

Sinovac Vaccine Trials

The Sinovac inactivated vaccine (candidate) was tested on rhesus macaques with reportedly good results.11)

AstraZeneca Vaccine Trials

In animal trials, Oxford's AstraZeneca vaccine failed to prevent infection by SARS-CoV-2, though there were signs of reduced disease in some of the animals.12)

CanSinoBIO Vaccine Trials

  • Immunogenicity and safety of a recombinant adenovirus type-5-vectored COVID-19 vaccine in healthy adults aged 18 years or older: a randomised, double-blind, placebo-controlled, phase 2 trial 13)

Janssen Vaccine Trials

Safety and Efficacy of Single-Dose Ad26.COV2.S Vaccine against Covid-1914)

Mix and Match Trials

Trials are ongoing to determine the effectiveness of mixing and matching different COVID-19 vaccine products, such as the MOSAIC study in Canada.

Critiques of COVID-19 Vaccine Trials

The phase III COVID-19 vaccine trials were never set up to demonstrate reduction in serious outcomes or interruption of transmission of the SARS-CoV-2 virus.15)

Regulator Concerns

An article was published in the British Medical Journal on March 21, 2021, 'The EMA covid-19 data leak, and what it tells us about mRNA instability' by Serena Tinari,16) looking at some of the 40MB of data that was hacked from the European Medicines Agency and sent to the BMJ. Some of the leaked emails express significant concern, in late November 2020, about the stability of the mRNA found in the products, worrying about “truncated and modified mRNA species present in the finished product” that would compromise efficacy.

“The complete, intact mRNA molecule is essential to its potency as a vaccine,” professor of biopharmaceutics Daan J.A. Crommelin and colleagues wrote in a review article in The Journal of Pharmaceutical Sciences. “Even a minor degradation reaction, anywhere along a mRNA strand, can severely slow or stop proper translation performance of that strand and thus result in the incomplete expression of the target antigen.”17)

Crommelin and colleagues note that specific regulatory guidance for mRNA based vaccines has yet to be developed, and The BMJ’s attempts to clarify current standards were unsuccessful.

By late December, the Agency had decided that “the quality of this medicinal product (Comirnity), submitted in the emergency context of the current (covid-19) pandemic, is considered to be sufficiently consistent and acceptable.”18)

Lack of Transparency

Aaron Siri has documented how the FDA has actively participated in obscuring data and documents related to COVID-19 vaccine trials. https://aaronsiri.substack.com/p/fda-doubles-down-asks-federal-judge?justPublished=true
