If you look at the human clinical trials that have been conducted this year by drug companies developing experimental vaccines for COVID-19, the participants in those trials have all been “healthy adults.” Take, for example, Moderna’s Phase 1 clinical trial for its mRNA-1273 vaccine, which included 45 healthy adults 18 to 55 years old. The same is true for the Phase 1/2 clinical trial for the BNT162b1 vaccine being developed jointly by Pfizer and BioNTech. That trial also involved 45 healthy adults between the ages of 18 and 55 years.1 2 3 4 5 6
The Phase 1 clinical trial for CanSino Biologics’ Ad5-nCoV vaccine included 108 healthy adults 45 to 60 years of age. The Phase 1/2 trial for Novavax’s NVX‑CoV2373 was limited to 131 healthy adults 18 to 59 years old. The Phase 1/2 trial for AstraZeneca/University of Oxford’s AZD1222 (formerly ChAdOx1 nCoV-19) vaccine involved 1,077 healthy adults 18 to 55 years of age.7 8 9 10 11 12
There were two age groups in Johnson & Johnson’s Phase 1/2a clinical trial for its Ad26.COV2.S vaccine. The first group consisted of 402 healthy adults 18 to 55 years old. The second group included 394 healthy elderly adults 65 years of age and older.13
All six of these experimental COVID-19 vaccine programs have at least three things in common. First, they have all moved into the Phase 3 clinical trial stage in which tens of thousands of healthy adults are being recruited to continue testing the safety and efficacy of the vaccines. Second, many of the people who participated in the trials experienced adverse events after getting the vaccines. Third, all of the participants were healthy adults.
Experimental COVID-19 Vaccines Have Produced Many Adverse Events
One reason that these COVID-19 vaccine development programs have proceeded to Phase 3 clinical trials is that the drug companies behind them determined that the earlier trials showed the vaccines stimulated sufficiently strong antibody responses by the immune system to merit further research and testing. The companies also judged the vaccines to be “generally considered” safe,14 15 16 17 18 19 20 21 22 23 24 25 even though the vaccines provoked adverse events in dozens of trial subjects–including some serious or severe adverse events, as in the case of the Moderna mRNA-1273, Pfizer/BioNTech BNT162b1, CanSino Biologics Ad5-nCoV, Novavax NVX‑CoV2373 and Johnson & Johnson Ad26.COV2.S vaccines.1 2 4 7 9 25
No serious or severe adverse events were reported in the Phase 1/2 trial for the AstraZeneca/University of Oxford AZD1222 vaccine before AstraZeneca announced on Sept. 8, 2020 AstraZeneca that it was pausing its Phase 3 trials on the vaccine in United States and the United Kingdom to investigate a case of transverse myelitis (a neurological condition caused by inflammation of the spinal cord) suffered by one of the volunteer trial participants.26 27
Phase 3 Clinical Trial for AZD1222 Still Paused Pending FDA Safety Review
The Phase 3 trial in the U.K. was resumed on Sept. 12 following a review by officials at the U.K.’s Medicines Health Regulatory Authority (MHRA), who reportedly concluded that it was safe to do so. The clinical trial in the U.S. remains on hold while the U.S. Food and Drug Administration (FDA) is investigating the “unexplained illness.” Recent news reports indicate that the FDA may, in fact, be expanding its investigation. FDA commissioner Stephen Hahn said:
Consistently, reports about the adverse events experienced by clinical trial participants receiving experimental COVID-19 vaccines have tended to downplay the events, with company spokespersons noting that vaccine reactions have been “mild or moderate” and short-lived. While they didn’t hide the fact that there were numerous serious or severe adverse events to the vaccines, neither did they highlight these reactions. Nor did they raise many concerns about the unknown long-term effects of all vaccine adverse events, regardless of their severity.3 12 25 30 31 32
Most People in the U.S. are Not Healthy
Perhaps most concerning is the apparent neglect to acknowledge the elephant in the room, which leads to the obvious question being asked by many Americans concerned about the safety of experimental COVID-19 vaccines being rushed to market: “If these vaccines are only being primarily tested on healthy adult volunteers under age 65 and a good number of them are suffering vaccine adverse events, then how will the elderly over age 65 and unhealthy adults and children react to the vaccines?”
This is not an insignificant question, given that most Americans are not healthy. Six out of 10 adults in the U.S. suffer from a chronic disease. Four out of 10 adults in the U.S. suffer from two or more chronic diseases. An estimated 10-20 million (13.5 to 27 percent) American children and adolescents suffer from a chronic illness or disability. An estimated 42.4 percent of adults in the U.S. are obese–9.2 percent qualify as severely obese. An estimated 13.7 million (18.5 percent) American children and adolescents qualify as obese. More than 131 million Americans, or 66 percent of all adults in the U.S., take prescription drugs.33 34 35 36 37
A study published in the journal Mayo Clinic Proceedings in 2016 found that less than three percent of Americans live a health lifestyle. Another study published in the journal Metabolic Syndrome and Related Disorders in 2018 found that only 12 percent of adults in the U.S. are metabolically healthy. These kind of studies abound.38 39
A sick and medicated America is the new norm. Tens of millions of children and adults in the U.S. are not healthy. How many and what kind of adverse events should they expect from experimental COVID-19 vaccines that are only being tested on healthy adults over a short period of time?
